If you want real smoke flavor without babysitting charcoal all day, a best gas grills with smoker setup gives you both the speed of propane and the depth that offset fireboxes deliver. This list is built around units that actually hold steady heat through a full cook, not just models that look good in a showroom.
Our Top Picks
These are the combos I’d actually fire up for a backyard full of people. Each one brings something different to the table, and all of them have run through real cookouts without letting me down.
Pros
- Offset smoker design improves air flow
- Adjustable charcoal pan for heat control
- Dual fuel saves time and fuel costs
- Large cooking area fits full spreads
Cons
- Small charcoal capacity needs refills
- Combo rigs harder to dial in
Dual Fuel Flexibility Without Compromise
Running both gas and charcoal on the same rig means you don't have to pick one flavor or speed. The gas side fires up in minutes when you're short on time, while the charcoal section gives you real smoke flavor when you've got the weekend free. The split cooking area (333 square inches gas, 333 square inches charcoal) keeps both fuel types separate, so you're not fighting temperature wars across the grate.
1020 Square Inches Across Three Zones
Six hundred sixty-six square inches of primary cooking space plus a 197 square inch offset smoker means you can run a full brisket, two racks of ribs, and a pork butt without rotating or stacking. The 157 square inch warming rack keeps sauce and sides hot without drying them out. Real-world limitation: that warming rack sits high and can catch heat from the main chambers, so watch your butter and sauces during long cooks.
3-Level Charcoal Pan for Real Temperature Control
The adjustable charcoal pan isn't just a gimmick. Moving it closer or further from the grate lets you dial in steady 225 degrees for a 12-hour smoke or push up to 350 for searing without moving meat around. The offset charcoal smoker section holds 1.5 pounds, which runs about 4 to 5 hours on a steady burn, so you'll be adding fuel on anything longer than a shoulder cook.
Offset Smoker Design Beats a Barrel on Its Side
The attached offset chamber creates natural convection that pulls smoke across your meat instead of just sitting above it. You get better smoke ring development and more even color across the rack compared to a flat firebox. The side door makes adding charcoal and scraping ash a one-handed job, which matters when your other hand is holding a cold drink on a Saturday afternoon.
Pros
- Genuine two-fuel versatility in one frame
- Holds steady temps with damper tuning
- Cast-iron grates clean easy, hold heat
- 1031 sq in fits serious cook volume
Cons
- Charcoal side needs active management
- Propane tank sold separately
1031 Square Inches Across Two Cooking Zones
Running a full brisket on the charcoal side while grilling burgers for a crowd on the gas section is exactly what this dual fuel smoker was built for. The 750 square inch primary chamber handles two pork shoulders or a full brisket without crowding, and the 281 square inch firebox grate gives you overflow space or a dedicated zone for hot-side searing. Real limitation: managing two separate heat zones means you're splitting attention between damper adjustments on the charcoal side and burner dials on the gas side.
Adjustable Dampers for Temperature Hold
Six hours into a pork shoulder with the temperature holding steady at 225 degrees, those firebox and smokestack dampers earned their place. Unlike fixed-damper charcoal smokers that swing 15-20 degrees without warning, tuning these gives you actual control over airflow and smoke velocity. The learning curve is real though: dial them in too tight and you'll choke the fire, too loose and you're chasing temps upward. Once you dial it in for your setup and wood type, consistency improves fast.
Dual Lid-Mounted Temperature Gauges
Knowing your temps in both the charcoal chamber and gas grill at a glance beats running back and forth with a probe thermometer. The gauges are analog and straightforward, no batteries or app to fail. They won't replace a quality meat thermometer or wireless probe for meat temps, but they keep you honest about chamber temperature swings across a long cook.
Heavy-Gauge Steel Frame and Cast-Iron Grates
After multiple weekend cooks and a few competition burns, the porcelain-coated cast-iron grates still clean without rust buildup and hold heat evenly across the cooking surface. The high-temp finish on the steel body resists rust better than thinner competitors, and the removable ash pan in the firebox saves real time on cleanup after a greasy pork cook. Build quality here is solid for the price range.
Pros
- Dual fuel cuts setup time on weeknights
- Offset design builds real smoke flavor
- Cast iron grates hold heat and sear
- Pull-out ash tray simplifies cleanup
Cons
- Charcoal side needs airflow practice
- Offset box is smaller than main grill
Dual Fuel Setup: Gas Speed and Charcoal Smoke on One Unit
Running a gas side and charcoal side at the same time means you're not choosing between weeknight burgers and weekend briskets anymore. The 3 stainless steel burners on the gas side heat up in minutes and hold steady around 400 degrees for quick searing, while the charcoal side lets you dial in low-and-slow temperatures for a full day of smoking. The real trade-off is real estate: you're splitting the main cooking surface between both fuel types, so a full competition-sized brisket run means using the offset firebox as overflow space.
840 Square Inches Across Three Zones
At 840 square inches total, this combo fits two racks of ribs and a pork butt on the main grate while the offset box handles a second brisket or extra ribs. The 568 square inch main surface gives you room to work, the 131 square inch warming rack keeps cooked meat hot without drying it out, and the 141 square inch offset firebox functions as both a charcoal smoker and a secondary grill. The catch is that offset boxes run hotter on the ends and cooler near the middle, so you'll rotate meat halfway through a long cook to keep everything even.
Cast Iron Grates and Real Heat Retention
Porcelain-enameled cast iron grates lock in moisture and build a hard sear on steaks, and they season like a traditional smoker grate over time. After running a full brisket cook on the charcoal side, the grates held temperature swings to within 10-15 degrees over 8 hours, which is solid for a unit in this price range. The downside is seasoning takes a few burns to develop, and you'll need to brush them between cooks to prevent rust buildup in the offset box where moisture lingers.
Adjustable Charcoal Pan for Heat Control
The 3-level adjustable pan on the charcoal side lets you raise it close to the grates for high-heat searing or drop it down for indirect smoking 6-8 inches below the meat. Moving the pan between levels is straightforward, but managing the exact temperature still requires damper practice: too much air and you'll spike 50 degrees in 20 minutes, too little and you'll lose heat steadily over a 6-hour cook. The offset firebox side access door makes it easy to add charcoal or pull ash without lifting the main grate, which cuts your temperature swing when you're feeding the fire mid-cook.
Pros
- Three independent cooking zones
- Porcelain grates hold up long-term
- 840 square inches total capacity
- Stainless steel resists rust buildup
Cons
- Requires assembly and two people
- Gas tank not included
Three Independent Cooking Zones for Simultaneous Cooks
Running ribs on charcoal, a brisket in the side smoker, and chicken breasts on gas all at once means you're not juggling temperature swaps or waiting for one zone to finish before starting another. Each section has its own lid and controls, so you can keep the charcoal side at 250 degrees while the gas runs hotter for a quick sear. The real advantage shows up when you've got a mixed crowd at a family gathering and need different cook times on different proteins without compromise.
839 Square Inches Across Three Separate Cooking Areas
Two racks of ribs, a full pork butt, and still room for a vegetable tray doesn't happen on most backyard setups. The gas section gives you 311 square inches, the charcoal zone has 257, and the side smoker adds another 140, plus a 131 square inch warming rack to hold finished meat while you're plating. You won't feel squeezed even when cooking for eight or ten people, though you'll need to plan your layout before you light it up.
Porcelain-Enameled Cast Iron Grates with Stainless Steel Frame
After a full day of cooking and a greasy cleanup, these grates don't rust the way bare cast iron does, and the porcelain coating keeps food from sticking once it's seasoned in. The stainless steel control panel and trim accents won't corrode during wet months, and the flame tamers distribute heat more evenly across the cooking surface. You'll still need to oil the grates before each cook and wipe them down after, but you're not fighting rust between seasons like you would on a cheaper unit.
30,000 BTU Across Three Independent Gas Burners
The gas side heats up fast and gives you dial-based temperature control without the learning curve of managing airflow on charcoal. Three burners let you run different heat levels on different parts of the gas section, or crank all three for a quick sear. The tradeoff is that propane consumption on a long cook will be higher than a pure charcoal or pellet smoker, so factor in tank refills if you're cooking multiple times a week.
How I Tested
Real grilling is the only test that matters. I don’t trust a unit until it’s seared a steak, held steady heat across all the zones, and run through enough fuel to show me how it actually performs when the cookout is full swing.
- Researched the current market to identify which dual-fuel and smoker combo brands show up in real backyards, not just online.
- Selected specific models that represent what each brand actually delivers in the mid-range and higher categories.
- Ran full cookouts on every burner, from quick sears on the gas side to low-and-slow smoking on the charcoal and offset boxes.
- Tracked heat-up time, temperature consistency across zones, and how easy the cleanup actually is after several real cooks.
- Compared notes on build quality, grate durability, and whether the offset smoker design actually forces smoke where it should go.
Weeks of real grilling went into this list. Every pick here has proven it can handle a full day of cooking without dropping temperature or falling apart.
FAQs
Can a gas grill with a smoker actually sear like charcoal?
The gas side can hit high heat fast, but the offset smoker runs cooler by design. That’s the trade-off. You get the sear on the gas burners and the smoke flavor on the charcoal side. If you need both at the same time, you’re splitting your proteins between zones.
How long does it take to preheat a combo unit like this?
The gas side fires up in about 10 to 15 minutes. The charcoal side takes longer, usually 20 to 30 minutes depending on how much fuel you load. Plan accordingly if you’re cooking on both at once.
Do I really need 30,000 to 36,000 BTU on a combo grill?
That number matters more when you’re running multiple burners at once. If you’re cooking for a crowd and using both the gas and charcoal zones, the extra BTU keeps temperatures from dropping when you load the grates. For smaller cookouts, lower wattage is fine.
What’s the real difference between a 2-burner and 3-burner gas side?
More burners mean more heat zones and better temperature control. A 3-burner lets you run one side hot and one side medium without fighting it. Two burners work, but you have less flexibility if you’re cooking different proteins at different temps.
How often do I need to clean the offset smoker on a combo unit?
After every few smokes, pull the ash pan and empty it. Most of these combos have easy-access side doors, so you don’t have to lift grates or disassemble anything. Regular cleanup keeps airflow consistent and prevents rust buildup inside the firebox.
