You want the smoky flavor of charcoal and the quick convenience of gas, but your patio has room for only one grill. A combo grill settles that argument by putting both fuel types in a single cart, so you can sear a steak on gas while brisket slowly picks up smoke on the charcoal side. The real question is which combo gets the details right — heat control, cooking space, and cleanup — and that is exactly what this guide sorts out for you.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Dual-fuel cooking opens up a whole new range of barbecue possibilities, and this look at the best combo grill options covers everything from compact two-burner models to full-size smokers built for a crowd.
Our Picks at a Glance
How To Choose The Best Combo Grill
Before you buy a dual-fuel grill, think about how you actually cook. Do you want a side-by-side layout, an offset smoker attached to the charcoal chamber, or a griddle surface in the mix? Each layout changes how you cook a full meal, and the right one depends on whether you mostly host big parties or just want weekend flexibility.
Cooking Area and Layout
The biggest difference between models is total cooking space, which ranges from around 448 square inches on compact carts up past 1,000 on the largest units. Look for a primary cooking zone that fits your usual crowd, then check whether the warming rack and any smoker box count toward that total — a 1,020-square-inch grill might still have only 666 square inches of actual grilling surface.
Gas Burners and BTU Output
BTU measures raw heat output, and higher numbers mean faster preheat and better searing. A typical two-burner combo lands around 24,000 total BTU, while larger three-burner models push past 34,000. You want enough gas power for a quick weekday cook, but remember the charcoal side does the heavy lifting when you want that deep smoky flavor.
Build Quality and Assembly Reality
Combo grills ship flat-packed, and assembly is the most common complaint across every model in this category. Expect anywhere from 30 minutes to a few hours of wrenching, and pay attention to whether the frame is alloy steel or stainless — that choice affects how the cart holds up after a few seasons of weather.

In-Depth Reviews
1. Char-Griller Dual-Function 2-Burner Combo
Our pick — 4.5★ from 400+ verified ratings; the strongest balance of quality and price.
The big-surface dual-fuel champ that switches between smoke and sear without breaking a sweat.
This combo grill earns its Best Overall badge with sheer size — 870 square inches of total cooking space lets you feed a crowd, and the separate fireboxes mean you can smoke meat on one side while grilling burgers on the other at the same time. Owners consistently praise the build quality, and the dual-fuel setup is the single most-cited reason people buy it, with the propane side proving excellent for vegetables and quick reheats.
The gas side runs on two stainless steel burners pushing 24,000 BTU, which reaches searing temperatures quickly. Two temperature gauges let you monitor each side independently, and the porcelain-coated cast iron grates hold heat well. The side burner adds a third cooking zone for sauces or a pot of corn.
The honest catch here is temperature control — gas temps run hot and are hard to fine-tune (buyers report roughly 300°F on low with one burner and 350–375°F on low with two), and the charcoal side can exceed 400°F, demanding your attention. Assembly is also a real project that buyers describe as challenging, so set aside a few hours with a second pair of hands.
What wins people over
- Massive 870 sq in cooking area for large cooks
- Dual temperature gauges for each side
- Side burner plus porcelain-coated cast iron grates
- EasyDump ash pan speeds up cleanup
The trade-offs
- Gas temperature is tough to regulate precisely
- Assembly is challenging and time-consuming
Reach for this if: you want one grill that can smoke, sear, and feed a party with 870 sq in to work with.
Look elsewhere if: you want dialed-in low-temp gas control — this one runs hot and demands monitoring.
2. Griddle Grill Combo 4-Burner
The 4-in-1 cart that flips between grill, griddle, charcoal, and stovetop for breakfast-to-dinner cooks.
This is the most flexible single cart in the lineup because it adds a stainless steel griddle surface on top of the usual gas and charcoal zones. Four main burners at 10,000 BTU each plus a 9,000 BTU side burner deliver a total of 49,000 BTU — the highest gas output in this guide — which means fast preheats and real searing power. The 448 square inches of space split between a 339 sq in main zone and a 108 sq in warming rack handle a full family meal at once.
The porcelain-enameled cast iron grates give you solid sear marks and resist rust, while the double-layer stainless lid holds heat without warping. Two large wheels and a handle make it easy to roll around the patio, and the slide-out grease tray keeps cleanup quick. Assembly runs a couple of hours, but the parts arrive labeled to keep it manageable.
The one consistent complaint is the charcoal fuel pan sitting too close to the grates with no way to adjust the distance — food can burn if you are not watching. As owners mention, it works well otherwise, and the sheer cooking versatility makes it a standout at this price.
Why it stands out: No other pick in this range combines a griddle, grill grates, charcoal pans, and a side burner in one rolling cart, and the 49,000 BTU total is the strongest gas output here.
Who should skip it: If charcoal distance control matters to you, the fixed-height pan will frustrate — plan to monitor food closely on that side.
3. Grills House ZH3005Y Combo
The biggest surface in the mid-range, with an attached offset smoker that turns it into a true BBQ rig.
If cooking space is your priority, this cart delivers a whopping 1020 square inches total, broken into a 666 sq in primary area, a 157 sq in warming rack, and a 197 sq in offset smoker. The numbers translate to real capacity — it holds up to 36 burgers at once, and the offset smoker infuses meat with deep smoky flavor while you use the main grates for faster cooks. Owners describe the versatility as the reason to buy, since gas, charcoal, and smoker can all run simultaneously.
Power comes from two stainless main burners at 12,000 BTU each plus a 10,000 BTU side burner, totaling 34,000 BTU. The piezo ignition lights without needing a battery, and the 3-level adjustable charcoal pan lets you raise or lower coal height for searing versus slow cooking. The charcoal pan holds up to 3.3 lb of fuel, with the smoker taking another 1.5 lb.
Assembly is the split decision here — some customers note a straightforward 30–60 minute build with no extra screws, while others hit unclear instructions and parts that do not line up perfectly. A few owners also flag durability concerns over time. The build quality itself earns consistent praise, and the smoked chicken results get glowing mentions.
Best for: anyone who wants an offset smoker and a full grill in one cart — 1020 sq in is the most real estate in the mid-range tier.
Keep in mind: assembly experience varies wildly by unit, and a handful of reviewers point out long-term durability worries, so check your parts early.
4. Royal Gourmet ZH3002N Combo
A side-by-side dual-fuel cart that rolls easily and hides the tank behind cabinet doors.
This one wins on maneuverability — two 6-inch wheels and two 3-inch lockable casters let you reposition it anywhere in the yard, and the bottom cabinet doors hide the propane tank and supplies for a cleaner look. The 759 square inches of cooking area splits into 592 sq in of grates and a 167 sq in warming rack, enough to cook 30 burgers simultaneously. Owners chose it partly for that tidy appearance, with the name-brand hood plate as a visual bonus.
The side-by-side layout gives you independent gas and charcoal zones, and cleanup stays simple with a slide-out ash tray on the charcoal side plus a large-capacity grease cup and tray on the gas side. Two side shelves with three integrated hooks each keep tools and seasonings within reach while you cook. Once fully assembled, the cart feels sturdy and performs well for everyday grilling.
The trade-off is assembly and initial build quality — the process takes hours with many pieces, and a few shoppers say the cart arrives with missing parts or feels less sturdy than expected while putting it together. One owner found the cooking surface smaller than anticipated for party-scale cooks, so measure your needs before committing.
Where it shines
- Great mobility with locking casters
- Cabinet doors hide the tank and gear
- 759 sq in feeds a decent crowd
- Easy slide-out ash tray and grease cup
Where it falls short
- Assembly takes hours with fiddly parts
- Some units arrive with missing pieces
Choose it for: a movable, tidy-looking combo where the tank-storage doors and easy rolling beat raw cooking capacity.
Think twice if: you need maximum surface for big parties — a few owners found the 759 sq in layout cramped.
5. Nice Cooker 663 Sq In Combo
Four porcelain-enameled cast iron grates that shrug off extreme heat and lay down even sear marks.
The defining feature here is the grates — four porcelain-enameled cast iron bars (two for the charcoal side, two for gas) rated to withstand up to 1020°F, giving you superior heat conduction and easy cleanup. The dual-zone layout splits into a gas side measuring 19.1 x 14.4 inches plus a 19.1 x 4.7 inch strip, and a charcoal side at 15.5 x 14.4 inches plus a 15.5 x 4.7 inch strip. Three 9,560 BTU burners and an 8,550 BTU side burner combine for 37,230 BTU of output, with a double-layer lid locking heat in.
Owners who got theirs assembled report even cooking and great BBQ results, with the gas side handling quick weekday cooks while the charcoal side delivers smoky ribs. The cart includes a storage cabinet for tools, side hooks, a #430 stainless bottle opener, and an easy-lifting charcoal system. Two lockable and two non-lockable 3-inch wheels keep it stable during use but easy to move.
The stainless steel frame resists rust, and the brand reportedly replaces damaged units without requiring a return.
The standout: heat-holding cast iron grates that resist rust and handle extreme temps make this a strong performer once it is built.
The catch: the build process demands patience — set aside a good chunk of time and keep the manual handy.
6. GRILL DEPOTS 2-in-1 Combo
The crowd-sized combo with three independently controlled zones and a grooved griddle pan for variety.
This cart combines a 4-burner gas grill, a charcoal grill, and a perforated griddle pan into one 673.1 square inch cooking surface, with 510.48 sq in of cast iron grids and a 162.62 sq in warming area. Three independently adjustable 10,000 BTU burners plus a 9,000 BTU side burner total 41,500 BTU, letting you manage different heat levels across zones at the same time — sear steaks on one side, cook eggs on the griddle, and smoke veggies over charcoal. The double-layer stainless lid resists warping even after months of use.
The perforated griddle pan has holes across the bottom so heat and smoke pass through food quickly and evenly, which makes it great for meat, fish, and veggies. Four wheels make it easy to roll across the patio, the pull-out oil drip tray collects grease, and the cast iron grates are non-stick for simpler cleanup. Assembly is a genuine positive here — buyers call the instructions clear and the build easy enough to finish as a two-person job.
The main limitation is the frame — it is not heavy-gauge metal, so treat it with care, and a few owners note the surface area feels limited if you stick to only gas or only charcoal. An occasional unit arrives with shipping damage, but customer service resolves those issues quickly.
Why it works
- Three cooking zones: gas, charcoal, and griddle
- 41,500 BTU across independently controlled burners
- Easy, clear assembly — a rare compliment here
- Large 673 sq in total capacity
What to watch
- Frame metal is on the lighter side
- Zone sizes shrink if you use one fuel only
Grab this if: you want to feed a crowd with gas, charcoal, and griddle all on one cart and a build that will not eat your evening.
Pass if: you need heavy-gauge construction — this frame prioritizes easy assembly over brute durability.
7. Captiva Designs Gas & Charcoal Combo
A 61-inch, family-sized cooking counter with evenly heating porcelain-enameled cast iron grates.
This premium cart stretches 61 inches wide, giving you a long cooking counter with independently controlled gas and charcoal sides. The cooking surface totals 690 square inches — 520 sq in of porcelain-enameled cast iron primary grates plus a 170 sq in stainless warm rack — and owners consistently praise how evenly the heat spreads across the grates. The dual-fuel flexibility gets its own wave of praise, with users loving the ability to cook different foods at different temperatures at the same time.
Three stainless burners work with an enameled charcoal tray to deliver even heat, and the temperature control earns a spot-on reputation. Cleanup is genuinely thoughtful: a full-size slide-out grease tray sits below the gas side with a tilt that funnels drippings into a hanging grease box, while a separate slide-out ash tray handles the charcoal side. The included adapter hose and detailed installation instructions earn positive mentions.
The honest caveats are assembly difficulty and the occasional shipping issue. Building this solo is tough — owners recommend a second person — and some units arrive with dented parts or misaligned bolt holes. A minority call the build a little flimsy for the price, though the cooking performance wins most people over.
The defining strength: even heat distribution across 690 sq in is the thing owners rave about, backed by easy slide-out grease and ash trays.
Who it is not for: solo assemblers — this one really wants two people, and shipping dents are a real possibility to inspect on arrival.
8. Sophia & William Dual Fuel Combo
A 690 sq in dual-fuel cart with a crank-adjustable charcoal tray for precise heat management.
The standout feature on this one is heat control: the charcoal side uses an adjustable tray with a crank handle, so you can raise or lower the coal bed to fine-tune temperature without lifting the grates. The gas side runs three stainless burners delivering 28,650 BTU, plus an 8,530 BTU side burner for sauces and veggies — a combined 37,180 BTU. The 690 square inches split into 520 sq in of porcelain-enameled cast iron primary grates and a 170 sq in warming rack, with 10 inches of cooking height under the closed lid.
Porcelain-enameled flame tamers over the gas burners spread heat across the full grilling surface, preventing hot and cold spots. Cleanup stays simple with a full-size push-out ash tray and a smoothly sliding grease tray with a cup for collected drippings. At 105 pounds, this is a solid, heavy cart that rolls on casters, and owners praise even heating and easy control.
The drawbacks are real: assembly runs about two hours and really needs two people, and a small number of buyers report severe rust after a couple of years, describing thin metal in the grill area. The gas side heats up slowly and tops out near 500°F, which limits aggressive searing, and the front vent is largely useless. Match those limits to your cooking style before buying.
What impresses
- Crank-adjustable charcoal tray for precise heat
- Even heat with no hot spots across the grates
- Sliding grease tray and removable ash tray
- Solid, heavy 105 lb build
Fair warnings
- Slow propane preheat, maxing near 500°F
- Some units show rust within two years
Pick this for: charcoal control — the crank tray gives you the finest heat adjustment in this price range.
skip it if: you expect blazing gas searing or worry about long-term rust on thinner metal panels.
9. GREEN PARTY 3-Burner Combo
A 685 sq in dual-fuel rig with lid-mounted dampers for hands-on flame and smoke control.
The defining feature here is the airflow system: lid-mounted dampers plus an invisible front air vent let you control oxygen and flame without opening the lid, which minimizes heat loss while you cook. Open the dampers wider for a hotter fire, close them for lower, slower heat — a level of control that suits anyone who likes to actively manage their cook. The charcoal side adds a crank-adjustable pan to set coal-to-food distance for better heat efficiency.
Gas power comes from three separate main burners plus one side burner, totaling a strong 37,000 BTU, so you can sear on one zone while slow-roasting ribs on another. The total cooking area spans 685 square inches on porcelain-enameled cast iron grates that resist rust and hold heat. Cleanup is handled by a grease management system with a cup plus a removable ash tray.
Performance earns positive reviews, but assembly splits opinion — some find it straightforward enough for one person, while others call it very challenging. A few units arrive with bent structural pieces or broken welds on the side tables, and some parts near the heat are prone to rust. The brand’s customer service draws strong praise for quickly sending replacement parts, which takes the edge off those quality worries.
Best for: grillers who want active control — the dampers and crank tray put flame management literally at your fingertips.
Consider before buying: build quality is inconsistent between units, so inspect carefully and lean on the praised customer service if anything arrives bent.
10. Sophia & William 3-Burner with Offset Smoker
The true 3-in-1 system — gas grill, charcoal grill, and offset smoker — with 840 sq in to work with.
This is the combo that adds a genuine offset smoker to the mix, making it a 3-in-1 cooking system for charcoal lovers who still want gas convenience. The attached side firebox pushes smoke and heat horizontally across the meat for that deep smoke ring, and a side access door lets you add charcoal and clean ash without lifting the grates. Total capacity hits 840 square inches — a 568 sq in main surface, a 131 sq in warming rack, and a 141 sq in offset smoker — enough to fit 30 burgers at once.
The gas side runs three stainless burners at 30,000 BTU for fast preheats and consistent temperature, while the charcoal side repeats the 3-level adjustable pan for searing low or slow-cooking high. Porcelain-enameled cast iron grates hold heat, resist rust, and create restaurant-style sear marks. Full-size removable ash and grease trays make post-cook cleanup genuinely easy.
Weight sits at a substantial 105 pounds, and buyers describe it as extremely sturdy, with food coming out great — smoked beefsteak gets glowing reports. Assembly is a bit of a struggle and takes time, but pieces all arrive present, and most owners consider it easily worth the effort. The one quibble is the top rack not moving back when the lid opens.
what separates it
- True offset smoker adds authentic smoke flavor
- 840 sq in across three cooking zones
- Extremely sturdy 105 lb build
- Easy pull-out ash and grease trays
What to expect
- Assembly is a struggle that takes real time
- Top warming rack does not pivot with the lid
Buy it for: the full BBQ package — gas, charcoal, and a real offset smoker in one sturdy cart that handles family gatherings.
Be patient with: the build; set aside a couple of hours and bring a helper, and the payoff is a very sturdy grill.
11. Oklahoma Joe’s Canyon Combo
The pitmaster’s dual-fuel rig — 1031 sq in of smoke and sear space with firebox dampers for real control.
This is the largest and most serious grill in the lineup, built for people who want authentic low-and-slow smoking plus fast gas grilling in one station. The charcoal side uses a true offset firebox with 281 square inches of grate space, enough for 15 wings or 6 burgers, while the main 750 sq in primary chamber smokes up to 2 pork shoulders and grills up to 12 burgers at once. The adjustable firebox and smokestack dampers let you maintain consistent temperatures and smoke flow like a dedicated pitmaster.
The gas side brings 36,000 BTU across three burners, reaching cooking temps quickly and holding even heat across the grates. Porcelain-coated cast-iron grates resist rust and retain heat, dual lid-mounted temperature gauges keep you honest on both chambers, and the firebox door gives easy access to load fuel without losing momentum. A removable firebox ash pan plus storage space under the grill rounds out the design.
Performance is the most-praised quality, with owners loving that they can grill and smoke at the same time and calling the smoke quality good even in its pricey tier. Assembly is straightforward and some buyers finish it in about an hour with two people. The durability feedback is mixed — a few owners mention rust appearing on the shelf surfaces quickly, especially if a cover is delayed, though most find the heavy-gauge steel built to last.
Why it leads the premium tier
- 1031 sq in total across main chamber and firebox
- Real offset smoker with adjustable dampers
- Heavy-gauge steel and high-temp finish
- Dual lid thermometers for both zones
Things to know
- Some owners see rust on shelves if no cover is used
- Large footprint at 68.9 inches wide
Pick this if: smoking and grilling are both serious hobbies — the offset design and 1031 sq in put real pitmaster capability on your patio.
Plan for: a cover from day one to protect the shelves, and a wide spot in your yard for the 68.9-inch footprint.
Understanding the Specs
Cooking Area in Square Inches
Total cooking area combines the primary grates, warming rack, and any smoker box into one number. A 1,020 sq in total might hide that only 666 sq in is actual grilling surface, so look at the breakdown. For a family of four, 400–500 sq in of primary space is comfortable; for regular parties, aim for 600 sq in or more.
BTU Output and Burners
BTU (British Thermal Units) measures how much heat a burner produces per hour. More BTU means faster preheat and hotter searing, but it does not automatically mean better cooking — even heat distribution matters just as much. Most combos land between 24,000 and 49,000 total BTU across two to four burners, with a smaller side burner for sauces.
