9 Best BBQ Grill With Side Burner | Beware the Low-BTU Trap

Check Price on Amazon

The Napoleon Rogue PRO 525 earns the top spot by combining a true infrared side burner with four high-output main burners and porcelainized cast iron cooking grids. The infrared side burner (over 12,000 BTU) delivers intense, even heat that can sear a steak or boil a pot of water faster than the standard atmospheric burners found on most side units in this list. The main cooking area of 517.5 square inches is paired with a durable black porcelain enamel lid and doors that resist weather and fingerprints, making this a grill that looks as premium as it performs after dark with white LED backlit control knobs.

Build quality is where the Rogue PRO sets itself apart from the mid-range competition. The frame uses thick metal and the included WAVE cooking grids feature reverse ridges for larger sear marks while the groove design holds juices against the food to retain moisture. Owners consistently praise the lack of flare-ups during high-heat cooking and note that even though it is gas-powered, the finished flavor closely mimics charcoal-grilled results. The 15-year spare part availability duration signals long-term support from the manufacturer — uncommon at this price tier.

The main drawbacks reported include overly excessive packaging (one reviewer noted it filled an entire recycling bin) and some units arriving with minor dents on the doors despite 90% assembly completion by delivery teams. A few users also observed that the back of the grill does not heat as evenly as the front, even with all burners on high. However, for the combination of infrared side burner performance, porcelain enamel durability, and North American manufacturing, this remains the most capable all-around BBQ grill with a side burner in its segment.

The Weber Genesis E-325 brings PureBlu burner technology — a tapered design that creates a consistent flame and even heat distribution across the porcelain-enameled cast iron grates. With 641 total square inches of cooking space (including a large sear zone for steak crust), this three-burner layout is deceptively spacious. Raised flame openings on the burners allow food debris to fall past them instead of clogging the ports, a design detail that directly translates to fewer corrosion problems over years of use. The FLAVORIZER bars catch and vaporize drippings, adding smoky flavor while funneling grease away from the burners to prevent flare-ups.

Assembly using the BILT app takes a smooth 1.5 to 2 hours, and Amazon offers professional assembly for those who prefer a hands-off experience. Owner feedback repeatedly highlights the fast heat-up time, excellent temperature recovery when the lid is opened, and the fact that even average grillers produce restaurant-quality results consistently. The side tables provide generous prep space for platters and seasonings, and the grease management system with a pull-out tray makes post-cook cleanup nearly effortless.

The most common criticism involves the warming rack being shallow — large buns or multiple skewers can feel cramped — and the grease catch tray being smaller than owners would like for long cook sessions. A few users noted that the gas can shut off unexpectedly on the low setting and that there is no built-in fuel gauge (though customer service sends a replacement gauge upon request). Despite these small gripes, the Genesis E-325 delivers the refined build quality and heat consistency that has made Weber the benchmark in residential gas grilling.

The Charbroil Pro Series breaks the mold with its modular cooking system — the Amplifire infrared technology sits beneath porcelain-coated cast iron grates, but you can swap in a heavy-duty cold rolled steel griddle (included) in under 90 seconds, or buy a Gas2Coal charcoal tray separately for impromptu charcoal grilling on the same gas-powered frame. This flexibility makes it the most adaptable grill in the mid-range category. The 45,000 BTU rating across four burners heats up to 500°F in under 10 minutes with even heat that keeps food moist and flare-ups minimal.

The 802.9 square inches of total cooking surface (535 sq in primary + 155 sq in warming rack) accommodates up to 25 burgers, and the side burner adds another station for sauces or side dishes. Owners praise the griddle for breakfast cooking — pancakes and eggs come out well — though the grease drain placement on the griddle is less ideal for bacon or sausage with heavy fat output. The warranty structure is solid: 10 years on burners, 3 years on the firebox, and 1 year on other parts, which is generous for this price tier.

Assembly is the main pain point. Several reviewers describe the instructions as unclear, especially regarding the battery pack installation for the ignition, and a missing nut can complicate the initial setup. The grill also produces heavy smoke during the required burn-in period before first use. Some users felt the charcoal tray takes longer to ignite than advertised. But for someone who wants one grill that can gas-grill, griddle-fry, and charcoal-smoke without buying three separate units, the Charbroil Pro Series delivers unmatched versatility.

The Royal Gourmet GA6402B offers the largest cooking surface in this roundup with 835 square inches total (five main burners at 10,000 BTU each, plus a 14,000 BTU sear burner and a 10,000 BTU side burner). This six-burner layout accommodates 8-10 people comfortably — the primary porcelain-enameled cast iron grates and flame tamers distribute heat evenly across the entire surface, eliminating the cold spots that plague smaller grills. The one-button electronic ignition delivers reliable starts even in humid conditions, and the four lockable caster wheels provide easy repositioning without needing to lift the heavy cabinet.

Owner satisfaction is high for the price. Multiple reviewers note that this grill performs on par with more expensive brands once assembled, delivering excellent results for steak, burgers, and even rustic bread. The blue porcelain-enameled lid resists rust and wipes clean easily. The sear burner produces a genuine high-heat zone for crust formation without overheating the entire cookbox. The side burner works well for sauces, and the rear burner (10,000 BTU) supports rotisserie cooking — though the rotisserie kit itself is not included.

Assembly is the main hurdle. Several reports estimate 3-4 hours of build time, not the 70 minutes suggested in the manual, and at least one reviewer noted that a thermal baffle part may be defective and should be discarded. The doors on some units arrived with minor dents, though the manufacturer replaced them promptly. While not as robust as a Weber or Napoleon in frame rigidity, the GA6402B represents the best value for large-surface, multi-burner cooking when side burner capacity is a priority.

The Royal Gourmet GA5403B packs seven burners (four main, one sear, one rear, one side) into a 5-burner cabinet design that delivers 74,000 BTU total output across 738 square inches of cooking space. The side burner is lidded, so it doubles as extra prep surface when not in use. The rear 10,000 BTU burner supports rotisserie cooking, and the 14,000 BTU sear burner handles high-heat steak finishing. Owners consistently mention that this grill heats up fast — one reviewer in Michigan reported reaching 750°F even in cold April weather — and that the cooking performance easily rivals more expensive competitors.

The build uses a powder-coated alloy steel frame with a porcelain-enameled lid that resists weather damage. Diamond-shaped porcelain-enameled cast iron grates produce attractive sear marks. The side shelf provides room for prep work within arm’s reach. Multiple owners describe this model as “the most grill for the money” and note that the value proposition is hard to beat for the burner count and cooking area at this price point.

Quality control issues appear in customer reports. Some units arrived with minor bent parts (easily straightened) or missing screws. One reviewer reported a serious fire hazard due to a faulty regulator, though this appears to be an isolated case. The side burner grate is too small for large pot diameters, and the cart feels slightly flimsy compared to premium frames. Assembly instructions also omit the side burner gas line routing, so you will need to trace the connections manually. For careful buyers willing to inspect and tighten every bolt, this is a high-value entry into serious multi-burner cooking.

The Captiva Designs 4-Burner focuses on delivering even heat through its porcelain-enameled cast iron main grates and stainless steel burners paired with enameled flame tamers. With 42,000 BTU total output and a 545 square inch cooking area (400 sq in primary, 145 sq in warming rack), it occupies the sweet spot for small to medium family gatherings. The side burner is fully functional for sauces and side dishes, and the full-size pull-out oil drip tray makes grease disposal fast and tidy.

Owner responses lean positive, with many appreciating the quick and even heat distribution, the sleek stainless steel cabinet appearance, and the practical storage space beneath the grill. The tool hooks and side shelves keep utensils organized. Most users completed assembly in about 1.5 hours with clear instructions, and the manufacturer offers responsive 24-hour customer support for any issues.

The most serious concern involves paint flaking inside the cookbox — one reviewer reported that paint particles (containing potential forever chemicals) came off during use, raising health and safety questions. That same reviewer experienced rapid rusting after only four uses. Other users reported minor cosmetic dents or scratches on arrival, though the seller offered rebates to resolve those complaints. If you purchase this model, inspect the interior cookbox finish carefully during the first burn-in and contact support immediately if you see any flaking. For those who get a clean unit, the performance-to-cost ratio is strong.

The Bestfire 68,000 BTU 5-Burner delivers a massive 647 square inches of cooking space (447 sq in primary cast iron grates plus a 200 sq in warming rack) and a 304 stainless steel outer body at an entry-level price. With six burners total (five main, one side) and a total output of 68,000 BTU, this grill targets buyers who want a big cooking surface without spending mid-range money. The push-button ignition, built-in thermometer, and heavy-duty wheels with two locking casters add practical convenience. The weather-resistant design means you can leave it on a covered patio year-round without immediate deterioration.

Multiple owners report that this grill heats fast, the cast iron grates cook evenly, and the side burner is genuinely useful for sauces. Assembly is manageable but requires careful attention — the instructions can be confusing, and the unit weighs about 88 pounds, so having a helper for lifting is recommended. The porcelain-enameled grates produce good sear marks on steaks and burgers, and the temperature gauge tracks accurately against external thermometers.

Significant quality concerns appear in the negative reviews. One owner reported stripped screw holes, poor fitment of parts, and a lower cabinet that appears to be tin rather than stainless steel despite the product description. Fat flare-ups caused the metal on one unit to discolor, and the base can feel top-heavy when the lid is opened fully. If you are willing to perform a thorough inspection and address any assembly defects immediately, the Bestfire offers impressive quantity of cooking area for the price. But buyer caution is warranted regarding long-term durability.

The MASTER COOK 4-Burner offers a 40,000 BTU main burner system plus a dedicated 12,000 BTU lidded side burner, totaling 52,000 BTU across 518 square inches of cooking space (400 sq in primary plus 118 sq in warming rack). The lid-mounted temperature gauge and piezo ignition system provide the basics at a price point that appeals to first-time gas grill buyers or those equipping a rental property. The stainless steel lid and control panel give it a more polished look than the price suggests, and the four casters allow easy repositioning.

Owners who had a positive experience highlight the sleek design with the hidden propane tank, the ease of assembly (approximately 1-2 hours), and the convenience of the side burner for tasks like boiling barbecue sauce or sautéing onions. The grill produces consistent heat and avoids the messy smoke and ash of charcoal. The swing-away warming rack is useful for keeping buns or low-and-slow items warm while the main grates handle direct heat.

The negatives center on temperature ceiling — one reviewer could not exceed 525°F, which prevented the high-heat char they wanted on steaks. Another noted the drip tray is riveted in place, requiring rivet removal for proper cleaning. Packaging is inadequate for the weight, and some units arrive with minor damage to the bottom panel. The side burner adjustment screw may need tweaking out of the box. For buyers who do not need extreme searing temperatures and can handle minor assembly frustrations, the MASTER COOK delivers a functional side burner experience on a tight budget.

The Charbroil Performance Series is the number-one gas grill brand in the USA for good reason — the FlavorMax cooking system uses an emitter plate design that produces consistent heat, reduces flare-ups, and keeps food juicy. With 435 square inches of primary cooking space and a 130-square-inch swing-away warming rack, this four-burner grill is sized for couples or small families rather than large parties. The electronic ignition fires reliably every time, and the GearTrax-enabled side shelf accepts a range of modular accessories (tool hooks included). The open cart design makes propane tank access simple.

Assembly is notably easier than most competitors at this level. Multiple owners completed the build in 90 minutes or less, praising the clear pictorial instructions and parts that are blister-packed by section. The grill heats up to 600°F within five minutes and maintains even temperature across the cooking surface. The lightweight cabinet is easy to move with two 7-inch heavy-duty wheels. Buyers upgrading from older Charbroil models appreciate the improved modern look in dark gray.

The main downsides are the absence of a dedicated side burner — this model uses a side shelf with tool hooks instead of a burner — so if the side burner is your mandatory feature, this is a pass. The deep 25-inch profile means standard grill covers may not fit. Some owners noted the open back design leaves the interior exposed to wind, and the entry-level build does not match the durability of pricier stainless steel competitors. For a reliable, no-fuss gas grill that gets the basics right without the side burner complexity, the Performance Series is a solid choice.
