9 Best Propane Grill With Infrared Rear Burner of 2026 for Backyard Roasting

The Lion L90000 40-inch built-in propane grill is a heavy-duty outdoor cooking appliance engineered specifically for permanent outdoor kitchen islands. Designed for backyard grillers, patio entertainers, and BBQ enthusiasts who demand commercial-grade durability, this unit anchors custom cooking stations with serious performance. Its wide stance and polished stainless finish give backyard islands an upscale look while offering the muscle needed for high-volume entertaining.

Real-world cooking performance centers around cast stainless steel burners that deliver steady, high-BTU heat across an expansive 802 square inch primary grate area. Searing thick steaks achieves deep caramelization without persistent cold spots, while the wide footprint allows you to set up distinct heat zones for slow roasting sausages on one side and searing chops on the other. The rear infrared burner shines during rotisserie cooking, bathing spinning chickens or prime roasts in steady radiant heat that self-bastes the meat to perfection.

Durability is where this grill truly excels. Crafted from 16-gauge 304 stainless steel, the firebox, hood, and cooking grids resist rust, corrosion, and weather wear throughout changing seasons. The double-lined hood minimizes exterior heat discoloration and preserves steady internal temperatures when cool patio breezes pick up. Unlike budget grills that use thin sheet metal burners prone to burn-through, these cast burners maintain structural integrity across years of high-heat cycles.

Maintenance and evening usability are well thought out. The pull-out drip tray captures excess drippings to minimize the risk of grease fires, making scrape-downs simple between barbecue sessions. Dual interior halogen lights illuminate the entire grate surface, eliminating the need to balance flashlights while flipping burgers after dark. However, setup requires planning. At 200 pounds, safely sliding the grill into an island cutout takes multiple sets of hands, and you must verify island cutout measurements and non-combustible clearances beforehand.

For homeowners and outdoor cooks investing in an outdoor kitchen remodel, the Lion L90000 provides a balance of heavy commercial construction, immense cooking area, and included specialty features. It avoids the steep price markup of luxury brands while delivering the raw heat, rotisserie versatility, and longevity required for serious backyard entertaining.

With 802 square inches of primary cooking space, this grill excels at multi-course backyard meal preparation. You can sear burgers at maximum output over two burners while maintaining a low-and-slow warming zone across the remaining grates for buns, ribs, and grilled sides.

The dedicated smoker box adds practical versatility to standard propane cooking. Filling the box with hickory, applewood, or mesquite chips lets you introduce rich wood flavor into pork chops, poultry, or fish without needing to fire up an auxiliary smoker.

The infrared rear rotisserie system delivers balanced, high-temperature radiant heat directly to rotating meats. This setup seals in natural juices rapidly, allowing you to produce rotisserie chickens, pork loins, and gyros with authentic rotisserie-house texture right on your patio.

Unlike many built-in grill heads that require expensive optional add-ons, the Lion L90000 comes equipped out of the box with premium grilling accessories. The package includes a heavy-duty rotisserie kit complete with a motorized spit rod capable of handling whole birds and large roasts.

A stainless steel smoker box is also included, sitting neatly between the burners to generate aromatic smoke quickly. Dual internal halogen lamps are pre-installed inside the cookbox, ensuring seamless nighttime operation without extra patio lighting fixtures.

The Charbroil Pro Series 4-Burner Gas Grill with Amplifire Infrared Technology is a versatile outdoor cooking machine built for the homeowner who wants more than just a standard gas grill. It combines a powerful propane grill, a built-in griddle, and the ability to run charcoal (with an optional tray) all in one cabinet-style unit. This is not a portable grill for campgrounds or tailgate lots; it's a backyard centerpiece designed for weekend BBQs, patio parties, and family meals where you want to cook everything from seared steaks and chicken to pancakes and fajitas on the same surface.

Who is it best suited for? Backyard grillers who love experimenting with different cooking styles will appreciate the 60-second swap between grill grates and griddle. BBQ enthusiasts who miss that charcoal smokiness can add the Gas2Coal tray and get the best of both worlds. Patio cooks and outdoor entertainers will find the 802.9 square inches of total cooking space enough for up to 25 burgers or 12 steaks at once, plus a warming rack for keeping sides hot. The side burner is handy for simmering sauce or boiling corn while the main grates are busy.

Real-world cooking performance is strong. The Amplifire infrared system spreads heat evenly across the 535 square inches of primary grilling space, so you don't get hot spots that burn one burger while leaving another underdone. Searing steaks works well - the cast-iron grates get hot fast and leave nice grill marks. The griddle surface heats consistently for pancakes, eggs, or chopped veggies. Temperature control is straightforward with four main burners plus a side burner, and the grill reaches 500 degrees in about ten minutes. For low-and-slow cooking, you can use indirect heat with the warming rack or go charcoal mode for real smoke flavor. Fuel efficiency is decent for a 45,000 BTU grill because the infrared system uses that energy effectively.

Build quality is solid for the price point. The lid is made of painted steel, the grates are porcelain-coated cast iron that resists rust, and the cabinet is sturdy enough to hold the weight. The two 8-inch wheels and two locking casters make moving it around the patio straightforward, but at 187 pounds you won't want to shift it often. Weather resistance is adequate for outdoor storage with a cover (sold separately). The griddle insert has a rear grease slot that channels drippings into the drip tray, making cleanup simpler than a full flat top.

Ease of setup and storage requires some assembly - plan a couple of hours with a friend. Once built, the cabinet offers enclosed storage for propane tank and tools. Cleaning the griddle is straightforward with a scraper and paper towels, and the porcelain grates can be brushed clean. The drip tray catches most grease, but you'll need to empty it regularly to avoid flare-ups. One realistic limitation is that the charcoal mode requires buying a separate tray (Gas2Coal), so if you want that smoky flavor, factor in the extra cost. Also, the grill is not portable - no folding legs or compact design, so it's strictly for stationary backyard use.

Overall, this is a practical recommendation for the serious backyard cook who wants one grill that can handle a variety of meals. It swaps between modes quickly, cooks evenly, and includes the griddle without extra charge. If you have a patio or deck and regularly host gatherings, this Charbroil Pro Series delivers versatility and solid performance without the price tag of a premium brand. Just be ready for the weight and assembly, and it'll serve you well for years of outdoor cooking.

The Onlyfire 40-Inch Built-In Propane Gas Grill is engineered specifically for outdoor kitchen islands, offering serious grilling real estate for dedicated patio cooks and backyard entertainers. If you are building a custom outdoor BBQ island or upgrading an existing space, this drop-in unit provides commercial-style looks and high heat output without requiring professional assembly out of the box.

Cooking performance is anchored by four primary burners putting out 14,000 BTUs each, paired with a dedicated 10,000 BTU rear infrared rotisserie burner. This configuration produces up to 80,000 BTUs of total power, making quick work of thick steaks with high-temperature searing while retaining the flexibility for low-and-slow indirect cooks. Having four distinct cooking zones allows you to easily roast vegetables on one side while charring smash burgers on the other.

With 885 square inches of total cooking area, capacity is a major strength. You can easily feed a crowd during summer holidays, game-day watch parties, or family reunions without cooking in multiple batches. The stainless steel grates retain heat effectively, ensuring pronounced grill marks and dependable heat transfer across the entire surface.

Durability is backed by food-grade 304 stainless steel across the primary body and components. Unlike lower-grade steel that corrodes under humidity, 304 stainless offers excellent rust resistance against rain, coastal air, and ambient outdoor weather. The double-walled lid helps lock in internal temperatures while shielding the exterior from excessive heat discoloration.

Setup is straightforward because the unit arrives virtually pre-assembled, requiring you to drop it into your pre-cut counter opening, secure the grates, and connect the propane line. However, at 175 pounds, you will definitely want an extra set of hands during installation. Maintenance is kept simple thanks to a slide-out grease management tray that funnels drippings away from open flames, keeping flare-ups in check.

While it lacks natural gas flexibility without sourcing aftermarket conversion parts, this Onlyfire model shines for propane grillers seeking an expansive, reliable, and sharp-looking centerpiece for their backyard kitchen.

With four independently controlled main burners plus a rear infrared burner, managing different temperature profiles across the 885 square inch cooking grate is remarkably simple. You can easily achieve high surface temperatures for a hard crust on ribeyes, or shut off the center burners to bake delicate seafood and slow-roast chicken indirectly.

The 10,000 BTU rear infrared rotisserie burner provides radiant, focused heat directly to spinning meats, basting them in their own juices while keeping flame contact indirect. Heat recovery after opening the lid is rapid, preserving cooking temperatures even on windy patio days.

Grease management is handled through a full-width, slide-out drip tray positioned underneath the firebox. This tray catches excess fats, marinades, and food residue, making routine post-BBQ cleaning quick and preventing dangerous grease accumulation near the burner tubes.

The heavy-gauge 304 stainless steel cooking grates can be cleaned with a standard grill brush while still warm, and the smooth exterior stainless surfaces wipe down cleanly with a damp microfiber cloth and stainless cleaner to preserve their factory sheen.

The ONLYFIRE GS374 is a 32-inch built-in liquid propane grill engineered specifically for drop-in outdoor kitchen islands. Designed for backyard grillers, patio entertainers, and DIY outdoor kitchen builders, this unit offers the refined appearance and firepower of a high-end commercial unit. If you host weekend barbecues, holiday family feeds, or just love searing thick steaks outdoors on a weeknight, this grill brings the required firepower and heavy-duty construction to anchor your cooking space.

Heat consistency and raw output stand out across the primary cooking grates. Powered by four independent 14,000 BTU main burners, the grill dishes out a total of 56,000 BTUs of direct heat, complemented by a 10,000 BTU rear infrared burner for an overall output of 66,000 BTUs. This multi-burner layout lets you set up distinct temperature zones with ease. You can sear burgers over high direct flames on one side while gently roasting vegetables or keeping barbecue chicken over indirect heat on the other. The heavy-gauge hood traps heat efficiently, preventing massive temperature dips when you lift the lid.

Durability is central to any built-in outdoor setup, and ONLYFIRE uses food-grade 304 stainless steel across the construction. Unlike cheaper 430-series metals, 304 stainless steel offers superior resistance to rust, oxidation, and coastal moisture. The cooking grates are thick and solid, retaining ample thermal mass for defined grill marks while remaining resilient against high-heat wire brushing. The enclosed firebox design prevents rain, wind, and outdoor debris from interfering with burner performance, giving you reliable flame control regardless of breezy backyard conditions.

Installation and daily upkeep are refreshingly straightforward. The head unit arrives fully pre-assembled in the box, meaning you do not have to spend hours assembling nuts, bolts, and loose firebox panels. Once you slide it into your island cutout, you simply secure the gas connection. The one-touch piezo ignition sparks the burners immediately without hassle. After your cookout, the slide-out front grease tray collects dripping fats and food particles, minimizing flare-up risks and keeping grease away from your countertop masonry.

Keep in mind that this is a permanent 147-pound fixture meant strictly for masonry islands, so it is not an option for portable tailgating or campsite trips. You also need to confirm that your island cutout dimensions match the required specifications before purchasing. For serious outdoor cooks looking to elevate their patio kitchen with heavy steel and rotisserie options, this built-in model offers top-tier cooking capacity and longevity.

The core strength of this 32-inch grill lies in its multi-zone heat flexibility. The four main tube burners produce 14,000 BTUs each, giving you blistering heat across the primary 31 by 18-inch cooking surface. This output is ideal for getting high-temperature crusts on steaks, pork chops, and smash patties.

For whole birds, roasts, and kebabs, the rear 10,000 BTU infrared burner delivers radiant radiant heat without direct flare-ups. This allows fats to drip down naturally while the exterior crisps evenly. The 31 by 5.3-inch elevated warming rack provides secondary space for buns, foil-wrapped sides, or holding finished meats at serving temperature during large cookouts.

Routine maintenance is essential for preserving the luster and performance of any built-in grill. The heavy 304 stainless steel grates brush clean easily when preheated, allowing grease to burn down cleanly between sessions.

A removable slide-out drip tray catches oil, fats, and char underneath the burners. Emptying and wiping down this tray after every few cooks prevents flare-ups and keeps grease from accumulating inside the firebox. To keep the exterior hood looking pristine, occasional wiping with a dedicated stainless steel cleaner will prevent water spots and airborne pollen build-up.

The Napoleon 700 Series 32-inch built-in gas grill is a serious investment for the backyard chef who wants permanent, high-end cooking equipment. This grill head is designed to be installed into an outdoor kitchen island or custom enclosure, so it's not for campers or tailgaters – it's for homeowners who love to entertain and demand professional-grade results from their propane setup.

In real-world use, this grill shines when you're cooking for a crowd. The four main burners pump out 66,000 total BTUs, and the wave-shaped stainless steel cooking grids heat evenly while giving you those picture-perfect sear marks on steaks and burgers. The infrared rear rotisserie burner is a standout – it radiates intense heat toward the rotating meat, so whole chickens, pork loins, or rib roasts come out with crispy skin and tender, juicy interiors without constant basting. The included rotisserie kit is commercial-grade, with a heavy-duty spit rod and sturdy forks that hold large cuts securely.

Temperature control is precise thanks to the ACCU-PROBE gauge mounted on the lid. You can dial in low heat for smoking brisket or high heat for fast grilling, and the lid holds temperature well thanks to the double-wall construction. The backlit control knobs are a nice touch – they glow blue when off and turn red when the burners are lit, adding both safety and ambiance to evening cookouts. Interior halogen lights let you see exactly what's happening on the grates without lifting the lid and losing heat.

Build quality is excellent. The grill is almost entirely stainless steel, with a heavy-duty lid that resists rust and dents. The 0.354-inch thick cooking grids are virtually maintenance free – they don't need seasoning like cast iron, and you can scrape them clean with a wire brush without worrying about damaging the surface. The dual-level sear plates above the burners vaporize drippings for flavor while channeling excess grease into the angular management trays, which are easy to remove and wash. This system significantly reduces flare-ups compared to other gas grills I've used.

Installation is manageable if you have a built-in space ready. Napoleon includes a 2-inch tolerance for the cutout, so you're not forced into an exact dimension. The extra-long gas flex line and electrical wiring give you some flexibility during setup. However, at 178 pounds, this grill head is heavy – you'll want a helper (or an appliance dolly) to move it into position. Once installed, it stays put. There are no wheels, so plan your outdoor kitchen layout carefully.

If you're a backyard griller who hosts weekend BBQ parties and wants a built-in gas grill that can sear, roast, and smoke with confidence, the Napoleon 700 Series is a fantastic choice. The rotisserie capability alone sets it apart from many competitors in this price range. Just be aware that this is only the grill head – you'll need to provide the surrounding cabinetry, side burners, and storage separately. For the serious outdoor cook who values even heat, easy cleanup, and professional features like integrated lighting, this grill delivers. It's not for everyone, but for the right buyer, it's a cornerstone of the outdoor kitchen.

If you're building an outdoor kitchen and want a grill that can do it all, the Hvlwyaz 28-inch built-in gas grill deserves a close look. This is a dual fuel model, meaning you can run it on propane for quick weeknight burgers or drop in the included charcoal tray for that smoky, wood-fired flavor that BBQ enthusiasts crave. It's designed to fit into an outdoor kitchen island, with a cutout width that adjusts from 31.1 to 33.6 inches, so it should work with most standard island builds.

This grill is best suited for backyard grillers and outdoor entertainers who host regular cookouts. If you love the convenience of gas but miss the taste of charcoal, the dual fuel setup is a huge plus. You can sear steaks over high heat on the four main burners (12,000 BTUs each) or crank up the rear burner for rotisserie chicken. The total cooking area of 653 square inches gives you plenty of room for a crowd, and the cast iron grates hold heat well for nice grill marks.

In terms of real-world cooking performance, the 48,000 BTUs should provide enough power for fast grilling and decent heat consistency. The independent burner controls let you create zones for direct and indirect cooking, which is handy for thicker cuts or bone-in chicken. The rear burner adds flexibility for rotisserie cooking, though you'll need to buy the rotisserie kit separately. For low-and-slow smoking, the charcoal tray lets you add wood chips or chunks, but keep in mind this isn't a dedicated smoker - it's more of a hybrid setup that works best for shorter smoking sessions.

Build quality looks promising with heavy-duty stainless steel that should resist rust and handle harsh weather. The lid feels solid, and the overall construction seems designed for permanent outdoor installation. The LED-lit control knobs are a nice touch for evening grilling, and the one-button ignition should start reliably as long as you have fresh batteries. Cleanup is straightforward thanks to the removable front grease tray - just slide it out and dump the drippings after each cook.

That said, there are a few realistic limitations. Since this is a new product with no verified reviews, it's hard to gauge long-term durability or how well the ignition system holds up. The cutout dimensions are specific, so measure your island carefully before buying. Also, the grill requires 2A batteries for the gas functionality, which aren't included - a small annoyance but worth noting. The price point of around $1,000 puts it in competition with established brands, so you're betting on the dual fuel feature and build quality.

Overall, the Hvlwyaz 28-inch built-in grill is a practical choice for anyone who wants both propane convenience and charcoal flavor in one unit. It's ideal for backyard cooks who already have an outdoor kitchen island or are planning one. If you value versatility and don't mind being an early adopter, this grill could be the centerpiece of your patio cooking setup. Just double-check your dimensions and keep a pack of batteries handy.

The four main burners deliver a combined 48,000 BTUs, which is plenty for searing steaks, grilling burgers, or cooking for a crowd. The cast iron grates retain heat well and leave nice sear marks. The rear burner adds rotisserie capability, though you'll need to purchase the rotisserie kit separately. For charcoal mode, the included tray lets you add lump charcoal or briquettes, and you can toss in wood chips for extra smoke. Heat distribution seems even across the cooking surface, but the lack of reviews means we can't confirm long-term consistency. For best results, use the independent burner controls to set up direct and indirect heat zones.

Cleanup is one of this grill's strong points. The removable front grease tray slides out easily, so you can dispose of drippings after every cook. The stainless steel exterior wipes down with a damp cloth, and the cast iron grates benefit from regular seasoning to prevent rust. The charcoal tray can be emptied and cleaned with a grill brush. Since this is a built-in model, there are no wheels or folding legs to maintain, but you should periodically check the burner tubes for clogs and keep the ignition contacts clean. Overall, maintenance is straightforward for a grill in this class.

The Napoleon Rogue PRO-S 625 is a natural gas grill that means serious business for backyard cooks. With 5 main burners plus infrared rear and side burners, this 7-burner setup is built for those who love to entertain and crave restaurant-quality results at home. Its massive 34.75x18-inch main cooking area gives you room to grill burgers for a crowd, sear steaks, or slow-roast a whole brisket without feeling cramped.

This grill is best suited for backyard grillers and BBQ enthusiasts who have a dedicated patio setup and want a permanent natural gas hookup. It's not for campers or tailgaters due to its heavy 198-pound weight and fixed gas line, but for weekend BBQs and outdoor parties, it's a powerhouse. The infrared sear station is a standout feature, generating incredibly high heat to give steaks that perfect crust without overcooking the inside. The rear infrared burner takes rotisserie cooking to the next level, letting you spit-roast chickens or roasts evenly while the main burners handle sides.

Cooking performance is top-notch. The 5 main burners distribute heat evenly across the cooking surface, so you won't get hot spots that burn one side of a burger while the other stays raw. Temperature control is precise, allowing you to dial in low-and-slow smoking for ribs or crank it up for fast grilling. The stainless steel construction resists rust and stands up to rain and sun, so your grill stays looking sharp through years of outdoor use. The warming rack is a nice touch, keeping buns or appetizers warm while you finish the main course.

Build quality feels solid. The lid is heavy and seals well to retain heat, and the grates are durable and easy to clean. The wheels are sturdy enough to roll the grill into place, but at nearly 200 pounds, you won't want to move it often. Setup requires a natural gas line connection, so you'll need a professional if you don't have one already. Cleanup is straightforward thanks to the grease management system that channels drips away from the burners, reducing flare-ups and making post-cook wipe-down simple.

One limitation is the lack of a dedicated side burner for sauces or sides, though the infrared side burner can handle that if needed. The weight and permanent gas hookup mean this grill is a commitment, not something you pack for a camping trip. But if you have a patio and love hosting backyard parties, the Napoleon Rogue PRO-S 625 delivers consistent heat, incredible searing, and enough space to feed everyone. It's a reliable workhorse for the serious outdoor cook.

The Napoleon Rogue PRO-S 625 excels in heat consistency and searing ability. The 5 main burners provide even heat across the large cooking surface, so you can grill burgers, chicken, and veggies at the same time without worrying about hot spots. The infrared sear station reaches extremely high temperatures for that steakhouse-style crust, while the rear infrared burner ensures rotisserie cooking is evenly done. Temperature control is precise, letting you go from low-and-slow smoking for ribs to high-heat grilling for steaks with ease. The stainless steel construction retains heat well, making it efficient for long cooks.

This grill is built to last. The stainless steel body is rust-resistant and designed to handle all weather conditions, from hot summer sun to rain and snow. The heavy lid seals tightly to keep heat in, and the grates are sturdy and easy to clean. The wheels are large enough to roll the grill on a patio, but at 198 pounds, it's not meant for frequent moves. The overall construction feels premium, with no flimsy parts. The grease management system effectively channels drips away from burners, reducing flare-ups and making cleanup easier. For backyard grillers who want a permanent fixture, this is a durable choice.

The Napoleon Built-In 700 Series 38-inch Propane Gas Grill Head is a top-tier outdoor cooking appliance designed for dedicated backyard grillers and BBQ enthusiasts who want a permanent, high-performance setup. This grill head is built to be installed into an outdoor kitchen island, and it comes with everything you need to start rotisserie cooking right away: an infrared rear burner and a commercial-grade rotisserie kit. With 5 main burners producing 78,000 total BTUs, it has the power to sear steaks, roast whole chickens, and cook for a crowd, all while maintaining even heat across its 35x18-inch cooking area.

This grill is best suited for homeowners with a dedicated outdoor kitchen space who love entertaining. It is not portable for camping or tailgating, but for backyard parties and weekend BBQs, it is a workhorse. The wave-shaped stainless steel cooking grids are 9 mm thick, which is unusually heavy for a gas grill. They provide excellent heat retention and produce those deep sear marks that serious grillers look for. The grids also prevent smaller foods like vegetables from falling through, which is a practical benefit when you are cooking multiple items at once.

The infrared rear burner is the standout feature here. It is perfect for rotisserie cooking because it radiates intense heat from the back, allowing the rotisserie motor to slowly turn the meat for even browning and self-basting. The included rotisserie kit is commercial grade, meaning it can handle a large turkey or a whole leg of lamb without wobbling. The failsafe ignition system lights the burners instantly with a jet of flame, so you never have to worry about a slow start or a dead battery. The backlit control knobs glow blue when off and turn red when the burners are active, which is a nice touch for safety and visibility during nighttime grilling.

Build quality is solid. The grill is made entirely of stainless steel, including the body, burners, and sear plates. The 9 mm thick cooking grids are virtually maintenance free, and the wave shape helps distribute heat evenly while preventing food from falling through. The dual-level sear plates protect the burners from drippings while directing grease to the angular management system, which reduces flare-ups and makes cleanup easier. The integrated storage under the grill keeps the rotisserie kit safe and accessible. The extra-long flex line and 2-inch cut-out tolerance make installation easier for DIY builders, which is a practical advantage for anyone planning a custom outdoor kitchen.

One realistic limitation is the weight. At 202 pounds, this grill head is not portable. It is designed to be built in permanently, so if you are looking for a grill to take to the campsite or tailgate, this is not the right choice. Also, the price is high, reflecting the premium materials and features. For casual grillers who only cook a few times a year, this may be more than you need. However, for the serious backyard chef who wants consistent heat, excellent rotisserie performance, and a grill that will last for years, the Napoleon 700 Series is a strong investment. It delivers on heat consistency, searing ability, and smoke flavor from the rotisserie, and the grease management system keeps things clean for low-and-slow cooks. If you have the space and the budget, this grill will become the centerpiece of your outdoor kitchen for years to come.
