The moment you start a steak on a standard grill, you dash inside to sauté mushrooms or simmer a sauce on the kitchen stove, letting smoke into the house and breaking the rhythm of an outdoor cookout. A grill with a dedicated side burner solves that friction by turning your barbecue station into a full outdoor kitchen, letting you boil corn, reduce a glaze, or sear vegetables without ever leaving the grates. Choosing the right combination of burner power, cooking area, and build quality determines whether that convenience lasts a single season or becomes a decade-long companion.

I’m Mohammad Maruf — the founder and writer behind WellFizz. Over years of analyzing backyard cooking hardware, I’ve broken down BTU ratings, stainless steel grades, and heat distribution patterns to separate grills that deliver consistent results from those that rust or underperform after a few uses.

This guide digs into the specifications that really matter for a balanced outdoor cooking station — from total surface area and material durability to the real-world heat output of both the main chamber and the auxiliary burner — helping you find the best bbq grill with side burner for your patio, deck, or campsite.

How To Choose The Best BBQ Grill With Side Burner

Selecting a grill with an integrated side burner means balancing the cooking power of the main grates with the utility of that extra burner. The table below highlights the most important specs to compare — here’s what each one means for your everyday grilling.

Total BTU vs. Per-Burner Heat

A high total BTU number looks impressive on the box, but the real question is how that heat is distributed. A 68,000 BTU grill with five main burners averages about 13,600 BTU per burner, which is solid for even cooking. A 71,000 BTU model with a dedicated sear burner can concentrate that energy into a smaller zone for steak crust. The side burner typically runs 9,000 to 12,000 BTU — enough to boil water or simmer a sauce but not to sear a large pan.

Grate Material and Cooking Surface

Porcelain-enameled cast iron grates retain heat better than bare stainless steel and create those desirable sear marks, but they are heavier and can chip if dropped. Stainless steel grates resist rust more aggressively but don’t hold heat as well, leading to cooler spots when you open the lid. The primary cooking area should comfortably fit your typical meal size — 400 to 550 square inches covers most family dinners, while 600-plus square inches handles larger gatherings.

Build Material and Cabinet Durability

The lid, control panel, and doors are often advertised as “stainless steel,” but the grade varies. 304 stainless steel resists rust and heat discoloration better than lower-grade alloys or painted steel. The cabinet should house a 20-pound propane tank securely, with a cutout that allows the tank to sit flat on the bottom shelf rather than tilting. Check that the wheels have at least two locking casters — grills can roll on uneven patio bricks if the wheels aren’t secured.

Side Burner Design and Placement

A lidded side burner doubles as a side shelf when closed, saving space and protecting the burner from rain. Open side burners offer easier access for larger pots but collect grease and debris faster. The burner’s location matters too — if it sits too close to the main lid, opening the grill can blow out the side flame on windy days. A drip tray that catches both main grill drippings and side burner spills simplifies cleanup considerably.

In‑Depth Reviews

Best Overall

1. Weber Genesis E-325 Liquid Propane Gas Grill

3 Main Burners + Sear ZonePorcelain-Enameled Cast Iron Grates

The Genesis E-325 defines the premium tier for a reason — its PureBlu burner system produces an even flame profile across the entire cooking surface, and the extra-large sear zone concentrates enough heat to lock in crust on multiple steaks at once. The porcelain-enameled cast iron grates hold heat tenaciously, and the FLAVORIZER bars vaporize drippings to create that smoke-kissed flavor without flare-ups.

Assembly time runs about ninety minutes with the BILT app guiding each step, and component fitment is notably tighter than mid-range grills — no misaligned screw holes or bent panels. The grease management system slides out from beneath the cookbox, making disposal a two-second task rather than a disassembly project. The side tables provide stable prep space, though the warming rack sits shallow and can feel cramped when loaded with multiple buns.

Long-term durability reports are strong: owners note even heat retention after years of regular use, and the porcelain coating on the grates resists rust better than bare cast iron. The main downside is the lack of a dedicated side burner on this specific model — you get a sear zone integrated into the main chamber rather than an auxiliary cooking station, which matters if you regularly boil sides outside.

Why it’s great

  • Extra-large sear zone delivers true restaurant-quality crust
  • Porcelain-enameled grates retain heat and resist rust
  • FLAVORIZER bars eliminate flare-ups while boosting flavor

Good to know

  • No dedicated side burner — sear zone is inside the main chamber
  • Warming rack is shallow for large buns or multiple side dishes
  • Premium tier requires a larger upfront investment
Most Versatile

2. Charbroil Pro Series 4-Burner Propane Gas Grill (463281024)

Amplifire Infrared TechnologyModular Griddle & Charcoal Tray

This Charbroil model breaks the standard grill mold with a modular cooking system that swaps between gas grates, a cold-rolled steel griddle, and a charcoal tray (sold separately) in under ninety seconds. The Amplifire infrared technology runs hot — reaching 500°F in under ten minutes — while preventing the flare-ups that plague traditional burner designs. The 802-square-inch total cooking area gives you real estate for twenty-five burgers or eighteen chicken breasts simultaneously.

The side burner sits under a lidded shelf that folds down to create a flat prep surface when not in use, and the 328-square-inch griddle plate fits over the main burners for breakfast spreads. Assembly requires roughly two hours, and the instructions can be vague about the electronic igniter battery pack, so expect to pause once or twice. Some units arrive with broken plastic end caps on the side shelves, though the manufacturer’s warranty and Amazon’s return policy cover replacements.

Built with an alloy steel frame and painted finish rather than full stainless steel, this grill prioritizes cooking flexibility over premium materials. The 45,000 BTU rating is modest compared to competitors, but the infrared system cooks more efficiently — lower BTU here does not mean lower heat. If you want one appliance that handles steaks, pancakes, and charcoal-grilled chicken without pulling out a second unit, this is the most functional choice.

Why it’s great

  • Swaps between gas grates, griddle, and charcoal in seconds
  • Infrared technology heats fast and prevents flare-ups
  • Massive 802 sq in total cooking area

Good to know

  • Assembly instructions can be unclear about the igniter battery
  • Side shelf plastic end caps may arrive damaged
  • Alloy steel frame is not as corrosion-resistant as 304 stainless
Sear Burner Special

3. Monument Grills 4+2 Burner Propane Gas Grill

Dedicated Sear BurnerStainless Steel Flame Tamers

Monument’s 4+2 configuration — four main burners, one side burner, and one side sear burner — delivers 72,000 BTU across 723 square inches, with the sear burner acting as a dedicated high-heat zone for finishing steaks. The stainless steel flame tamers spread heat evenly across the porcelain-coated cast iron grates, and the knob lights add visibility during evening cooking without being distracting.

Assembly typically takes around two hours, though the flex tubes connecting the side burners require careful routing to avoid kinks that restrict gas flow. The large storage cabinet fits a 20-pound propane tank plus tools, and the locking casters keep the unit planted on deck boards. Owners consistently note that the side sear burner outperforms standard side burners for achieving a proper crust, making this a strong pick for steak-focused cooks.

The brushed stainless steel finish looks premium but is lighter gauge than high-end models — the cart feels solid, not tank-like. Casters are functional rather than rugged and may need replacement after a few seasons on rough concrete. Heats quickly and cooks evenly across all burners, with minimal cold spots even when running all six at once.

Why it’s great

  • Dedicated side sear burner for restaurant-quality crust
  • Stainless steel flame tamers distribute heat evenly
  • Illuminated knobs improve visibility during night grilling

Good to know

  • Side burner flex tubes require careful routing during assembly
  • Casters are functional but not heavy-duty
  • Stainless steel is lighter gauge than premium competitors
Dual Fuel Ready

4. Monument Grills 4-Burner Natural Gas / Propane Grill

Convertible NG/LPClearView Lid

If your home has a natural gas line, this Monument model saves you from refilling propane tanks: it runs on liquid propane out of the box, but the Monument conversion kit (sold separately) switches it to natural gas in about twenty minutes. The four 304 stainless steel burners deliver 60,000 BTU across 700 square inches, with porcelain-coated cast iron grates that clean up easily and resist chipping.

The ClearView lid includes a large glass panel that lets you monitor food without opening the lid and losing heat. Assembly is straightforward for a handy person, though the side burner instructions can be confusing if you encounter them for the first time. The cabinet is made from cold-rolled sheet steel rather than full stainless, but the brushed finish on the front panel hides fingerprints well.

Users report the grill reaches nearly 700°F, providing solid heat for searing. The grease pan slides out for cleaning, and the warming rack offers 190 square inches of space for toasting buns or keeping sides warm. The panel-mounted LED controls look sharp but add a potential failure point over time.

Why it’s great

  • Converts between propane and natural gas with a simple kit
  • ClearView glass lid retains heat while monitoring food
  • 304 stainless steel burners resist corrosion

Good to know

  • Side burner assembly instructions can be tricky
  • Cabinet body is cold-rolled sheet, not full stainless
  • LED controls add a potential electrical failure point over time
Rotisserie Ready

5. Royal Gourmet GA5403C 5-Burner Propane Gas Grill

74,000 BTU Total OutputRear Rotisserie Burner

The GA5403C packs seven burners — four main (10,000 BTU each), a 14,000 BTU sear burner, a 10,000 BTU rear rotisserie burner, and a 10,000 BTU lidded side burner — into a 738-square-inch cooking area. The rear burner supports a rotisserie spit (sold separately), allowing you to slow-roast whole chickens or roasts while using the main grates for sides. The porcelain-enameled cast iron grates hold temperature well, and the lid’s powder-coated finish resists the elements better than painted steel.

Assembly takes four to five hours for most users, partly because parts come unlabeled and the instruction manual groups similar-looking bolts without clear differentiation. The side burner lid folds down into a shelf, and the right-side prep table provides ample space for seasonings and platters. The electronic ignition lights reliably even in breezy conditions, and the built-in thermometer reads accurately after a quick calibration.

Some units arrive with minor cosmetic dents from shipping, which can usually be bent back without affecting function. The sear burner is a high-heat zone rather than true infrared, but it still reaches temperatures that produce a solid crust. Over time, the diffusion plates may need replacement as they warp from repeated high-heat cycles.

Why it’s great

  • Rear rotisserie burner for slow-roasting whole birds
  • 74,000 BTU total output with separate sear and side burners
  • Porcelain-enameled lid resists rust better than painted steel

Good to know

  • Assembly is time-consuming with unlabeled parts
  • Sear burner is high-heat zone, not true infrared
  • Diffusion plates may warp after extended high-heat use
Solid Mid-Range Build

6. NutriChef NCGRIL2 5-Burner Propane Gas Grill

52,000 BTU TotalPowder-Coated Body

NutriChef’s NCGRIL2 sits at a price point that often surprises buyers with its solid feel — the powder-coated body and stainless steel control panel give it a heft that belies its mid-range positioning. Four main stainless steel tube burners produce 52,000 BTU total, plus a 10,000 BTU side burner for sauces or sautés. The heavy-duty cast iron cooking grid covers 443 square inches of primary space, adequate for four to six people.

Assembly runs about two to three hours, and the instructions are clearer than many competitors in this tier. The igniter wire must route along the designated path to avoid pinching against the tank bracket — a detail the manual covers if read carefully. The removable drip tray is a genuine plus: it slides out from the front rather than requiring you to reach under the hot grill, making post-cook cleanup significantly easier.

Heat distribution across the grates is even, and the burners respond quickly to knob adjustments. The side shelves fold for more compact storage. The painted finish on the lower cabinet is less durable than full stainless steel but holds up well when stored under a cover between uses.

Why it’s great

  • Removable front drip tray simplifies grease cleanup
  • Heats quickly and distributes heat evenly across the grates
  • Solid construction for the mid-range price tier

Good to know

  • Painted cabinet is less rust-resistant than full stainless steel
  • Igniter wire must be routed carefully during assembly
  • Primary cooking area is smaller than some competitors at 443 sq in
High Heat Entertainer

7. Royal Gourmet SG6002R 6-Burner Propane Grill

71,000 BTU TotalKnife Holder & Storage Basket

This 71,000 BTU grill features five main burners at 10,000 BTU each, plus a 12,000 BTU sear burner and a 9,000 BTU side burner, spanning 714 square inches of total cooking space. The sear burner sits between the main burners and the side burner, creating a dedicated high-heat zone that reaches temperatures capable of crusting a ribeye in under three minutes per side. The side shelves include tool hooks and a knife holder, keeping utensils within arm’s reach.

Assembly is a half-day project for most — the instructions are mostly clear, but some screw holes may not align perfectly on the steel frame, occasionally requiring you to enlarge them slightly. The stainless steel lid and cabinet doors look attractive out of the box, but the steel gauge is thinner than premium models, and some owners report rust spots forming on the cabinet after two years in humid climates. The heat spreaders may also begin to disintegrate over extended use.

For the cooking performance alone, this grill delivers serious output for large gatherings. The sear burner makes a noticeable difference in steak quality, and the warming rack keeps finishing sides hot without overcooking. A copper grill mat is a common accessory recommendation to simplify cleanup on the main grates.

Why it’s great

  • Dedicated 12,000 BTU sear burner for superior steak crust
  • 714 sq in accommodates large parties of 8-10 people
  • Knife holder and tool hooks keep utensils organized

Good to know

  • Thin steel gauge susceptible to rust in humid environments
  • Assembly may require minor screw hole adjustments
  • Heat spreaders can disintegrate after extended use
Griddle Combo

8. GRILL DEPOTS 6 Burner Propane Gas Grill

Reversible Griddle Plate620 Sq In Cooking Area

This model differentiates itself with a reversible cast iron griddle plate — smooth side for pancakes, eggs, and bacon; ridged side for steaks and chicken with the grease channeling away for leaner results. Six main burners (10,000 BTU each) power the 620-square-inch total cooking area, plus a 9,000 BTU side burner for sides. The cabinet doors offer enclosed storage for the propane tank and accessories.

Assembly requires a few hours and benefits from having a second person hold panels while bolts align. The brushed stainless steel body looks polished, but buyer feedback indicates the construction leans toward economy-grade rather than heavy-duty — fine for weekend cooks but likely not built for daily commercial use. The pull-out oil drip tray works effectively, catching grease from both the griddle and main burners in one central pan.

Cooking versatility is this unit’s strongest argument. You can sear burgers on the cast iron grates, then swap to the griddle for breakfast sides, all while simmering baked beans on the side burner. The four wheels make it easy to reposition, and the compact layout fits smaller patios better than extra-wide models.

Why it’s great

  • Reversible griddle plate for breakfast and dinner cooking
  • Central pull-out drip tray simplifies cleanup for grease and residue
  • Compact footprint fits smaller patios and decks

Good to know

  • Economy-grade construction not built for heavy daily use
  • Assembly requires a second person for panel alignment
  • Side burner is lower BTU than some competing models
Color & Heat

9. Sophia & William 4-Burner Gas BBQ Grill

Blue Stainless FinishDouble-Layer Lid

The Sophia & William grill stands out visually with a blue powder-coated lid and stainless steel accents, but the real story lies in the double-layer lid design that traps heat more effectively than single-wall lids in this price range. Four stainless steel burners generate 42,000 BTU total (32,000 BTU main, 10,000 BTU side burner), covering 542 square inches of cooking space. The porcelain-enameled cast iron grates distribute heat evenly and resist rust better than uncoated iron.

Assembly is straightforward with clear instructions, taking most users about two hours. The four galvanized casters roll smoothly, and the side burner functions well for simmering or boiling. The built-in thermometer reads accurately, and the control knobs give reliable flame adjustment from low simmer to high sear. The unit feels solid when fully assembled, with no wobble even on slightly uneven ground.

Long-term durability reports are mixed: some owners report the flame disperser supports rusting through after eighteen months, and the temperature control can jump from 300°F to 600°F without a stable middle range. For weekend use under a quality cover, this grill performs well, but it may not withstand year-round exposure in wet climates without accelerated corrosion.

Why it’s great

  • Double-layer lid design retains heat better than single-wall lids
  • Porcelain-enameled cast iron grates provide even heat distribution
  • Unique blue finish adds personality to the patio

Good to know

  • Flame disperser supports may rust after 18 months in wet climates
  • Temperature control can jump between low and high with limited middle range
  • Galvanized casters are functional but not heavy-duty
Entry-Level Convenience

10. MASTER COOK 4 Burner Gas Grill with Side Burner

52,000 BTU TotalPiezo Ignition System

MASTER COOK’s entry-level model delivers a balanced 52,000 BTU across four main burners (40,000 BTU) and a lidded side burner (12,000 BTU), with a 518-square-inch total cooking area. The piezo ignition system lights reliably on the first or second click, and the porcelain-coated warming rack keeps finished food hot without additional burner power. The cabinet hides the propane tank, creating a cleaner look than exposed-tank models.

Assembly takes about two hours, though the packaging is thin for a grill of this weight — some units arrive with bent panels or scuffed paint, though the grill itself usually remains functional. The instructions can be confusing in spots, and the drip tray is riveted into place, requiring you to remove rivets if you want to clean it thoroughly. Four wheels provide easy mobility, and the side burner lid folds into an extra shelf when not in use.

Cooking performance is decent for the price point: the main burners reach a maximum temperature around 525°F, which is sufficient for standard grilling but won’t deliver the heavy char some steak enthusiasts want. The temperature controls are smooth and precise within that range, and the automatic start makes lighting effortless. A solid introduction to gas grilling that leaves room for a future upgrade.

Why it’s great

  • Reliable piezo ignition lights on the first click
  • Lidded side burner folds into a prep shelf
  • Hidden propane tank cabinet provides a clean appearance

Good to know

  • Packaging is thin — units may arrive with minor cosmetic damage
  • Drip tray is riveted, making deep cleaning difficult
  • Maximum temperature of 525°F limits searing capability
Budget Large Cooker

11. Bestfire 68,000 BTU 5 Burner Propane Gas Grill

68,000 BTU Total304 Stainless Steel Body

The Bestfire 68,000 BTU grill packs five main burners plus a side burner into a 647-square-inch cooking area, with a 304 stainless steel body that resists rust better than the painted cabinets found on many budget grills. The 447-square-inch primary area uses porcelain-enameled cast iron grates that hold heat well, plus a 200-square-inch warming rack. Four heavy-duty wheels (two locking) make repositioning manageable despite the 88-pound weight.

Assembly is the most challenging part of ownership — expect about three hours, and start by watching the manufacturer’s video tutorial before opening any hardware bags. The instructions contain confusing steps, and some screw holes may not align perfectly. The cabinet doors are stainless steel on the front but painted steel on the sides, which can lead to surface rust if the grill lives outdoors uncovered. Some users report the metal discoloring from high-fat drippings that cause flare-ups, so keeping the flame tamers clean is important.

When properly assembled and maintained, this grill heats up fast and cooks evenly across the full surface. The side burner is genuinely useful for keeping sauces warm or boiling corn. At this price point, you get a lot of cooking real estate and decent build materials, though the overall fit and finish reflect a budget production economy rather than precision manufacturing.

Why it’s great

  • 304 stainless steel body resists rust better than painted cabinets
  • 647 sq in total cooking area fits up to 40 burgers
  • Porcelain-enameled cast iron grates retain heat evenly

Good to know

  • Assembly instructions are confusing — watch the video tutorial first
  • Side panels are painted steel, not stainless, and may rust
  • High-fat foods can cause discoloration and flare-ups

FAQ

What BTU rating should a side burner have to boil water?
A side burner needs at least 9,000 BTU to bring a standard pot of water to a rolling boil in a reasonable time. Burners rated at 10,000-12,000 BTU will boil water faster and maintain a stronger simmer for sauces or corn on the cob. Below 8,000 BTU, you may find the water takes too long to reach temperature for practical use during a cookout.
Can I convert a propane grill with side burner to natural gas?
Some grills, like the Monument Grills Convertible model, come designed for dual fuel from the factory and require only a manufacturer-approved conversion kit to switch. Most standard grills cannot be safely converted because the regulator and orifice sizes differ between propane and natural gas. Attempting an unofficial conversion can create a fire hazard and voids the warranty. Always use the manufacturer’s official conversion parts if available.
How do I prevent rust on my grill’s side burner?
Keep the side burner covered when not in use — either with its own lid (if lidded) or a full grill cover. After each use, burn off residue by running the burner on high for five minutes, then brush the burner cap with a stiff wire brush once it cools. Avoid letting greasy pans sit on the side burner after cooking, as acidic food residues accelerate corrosion on stainless steel surfaces.
What size grill fits a standard 20-pound propane tank cabinet?
Most freestanding cabinet-style grills with a side burner are designed to hold a standard 20-pound propane tank inside the lower cabinet. The tank requires a cabinet that is at least 12 inches wide, 12 inches deep, and 18 inches tall. Check the product dimensions for an accessible cutout or door that allows the tank to slide in and out without removing the grates. Some models include a tank-retaining bracket or strap to keep the cylinder secure during movement.

Final Thoughts: The Verdict

For most users, the bbq grill with side burner winner is the Weber Genesis E-325 because it delivers unmatched heat consistency, premium build quality, and the sear zone power that turns everyday grilling into restaurant-quality results, all backed by decades of reliable engineering. If you want a grill that switches between gas, griddle, and charcoal cooking in under two minutes, grab the Charbroil Pro Series. And for steak-focused cooks who want a dedicated sear burner without jumping to the highest price tier, nothing beats the Monument Grills 4+2 Burner.
