Deciding between the instant heat of propane and the smoky depth of charcoal no longer means giving up counter space or maintaining two separate grills. A gas charcoal combo grill merges both cooking styles into a single unit, giving you the flexibility to sear a steak over gas flames on a weeknight or spend a Sunday slow-smoking pork shoulders over lump charcoal without leaving your patio.
I’m Mohammad Maruf — the founder and writer behind AirfryerBite. I’ve spent years analyzing fuel systems, burner layouts, and material construction across dozens of dual-fuel grills to identify which models actually deliver consistent heat and real charcoal flavor without frustrating assembly or flimsy metal.
This guide breaks down the top contenders for your backyard by comparing cooking area, BTU output, grate materials, and temperature control features so you can confidently choose the best gas charcoal combo grill for your specific cooking style and space.
How To Choose The Best Gas Charcoal Combo Grill
Buying a dual-fuel grill means balancing two different heat systems in one chassis. The wrong choice can leave you with a gas side that struggles to sear or a charcoal side that smothers instead of smokes. Here is what actually matters when comparing models.
Primary Cooking Area vs. Total Advertised Space
Manufacturers love to quote total square inches that include warming racks and side shelves. Focus on the primary cooking area — the actual grates where meat touches flame. A model with 450 to 520 square inches of primary space comfortably handles 12 to 16 burgers or a full brisket. Anything less than 333 square inches per side in a combo unit feels cramped when cooking for more than four people.
Burner Configuration and BTU Distribution
Total BTU output matters less than how that heat is spread. A two-burner gas side rated at 24,000 BTU can sear beautifully if the burners run the full length of the cooking chamber. Three-burner setups around 37,000 BTU offer better zone control — you can crank one side for direct heat while using the other for indirect roasting. Look for independent control valves per burner, not a single gas rail.
Grate Material: Cast Iron, Porcelain-Enameled, or Stainless Steel
Porcelain-enameled cast iron grates are the sweet spot for combo grills. They hold heat like raw cast iron but resist rust and food sticking better than bare cast iron. Stainless steel grates last longer in humid climates but never reach the same searing temperature as enameled cast iron. Avoid thin chrome-plated wire grates — they warp under high heat and lack the thermal mass needed for good grill marks.
Charcoal Side Airflow and Ash Management
The charcoal compartment needs more than just a grate and a lid. Adjustable dampers on the firebox and smokestack let you control oxygen flow for low-temperature smoking versus high-heat searing. A height-adjustable charcoal pan adds real versatility, letting you bring coals closer for crust or drop them down for slow cook sessions. Removable ash pans or ash drawers make cleanup faster than scooping ash out of a fixed firebox.

In‑Depth Reviews
1. Oklahoma Joe’s Canyon Combo DLX
Oklahoma Joe’s builds this unit around a true offset smoker barrel paired with a three-burner gas grill, giving you 1,434 square inches of total cooking area. The 36,000 BTU gas side fires up quickly for direct grilling, while the charcoal firebox with adjustable dampers and smokestack allows proper low-and-slow smoking at 225°F. Two large rubber-treaded wagon-style wheels roll easily over grass or gravel, making it practical for moving around a large yard or driveway.
The integrated fuel gauge on the propane tank is a thoughtful touch — you can see how much gas remains without lifting the tank. Three tool hooks keep spatulas and tongs off the side shelves, and a flat bottom shelf holds extra wood splits or a spare propane tank. The pivoting cool-touch lid handles are comfortable even during long smoking sessions.
Assembly is the main hurdle here. At 191 pounds and with a horizontal smoker design, this grill requires at least two people and several hours to put together. The painted steel interior requires seasoning and regular maintenance to prevent rust. For backyard cooks who want one station that smokes properly and grills fast, this combo delivers the most dedicated smoker performance of any model here.
Why it’s great
- True offset smoker firebox for authentic low-and-slow smoking
- Massive 1,434 sq. in. total cooking area handles large gatherings
- Fuel gauge and large wheels add genuine convenience
Good to know
- Heavy unit at 191 lbs with complex assembly
- Painted steel interior needs regular care to prevent rust
2. MFSTUDIO 3 In 1 Gas and Charcoal Grill Combo
The MFSTUDIO combo uses three stainless steel burners to deliver 37,000 BTU across the gas side, which is enough raw power to get cast iron grates screaming hot for steakhouse-quality searing. The 520 square inches of primary cooking area sit on porcelain-enameled cast iron grates, combining the heat retention of cast iron with an enamel coating that resists rust and makes food release easier. An adjustable enameled charcoal tray on the charcoal side gives you control over coal proximity for different cooking techniques.
Two double-layer hoods with built-in thermometers let you monitor temperatures on both sides without lifting the lid and losing heat. The side burner adds 170 square inches of warming rack space, and the full-size slide-out grease tray plus ash drawer make post-cook cleanup relatively painless. Integrated tool hooks keep your utensils within reach without cluttering the cooking surface.
Assembly requires attention to detail — the manual advises not to tighten screws completely until the main frame is built, which is a common point of confusion for first-time builders. The steel frame feels solid once assembled, but the casters are more suited for smooth patios than rough terrain. This grill is ideal for cooks who prioritize high-heat gas performance and want a charcoal side that handles smoking rather than just grilling.
Why it’s great
- 37,000 BTU output delivers serious heat for searing
- Porcelain-enameled cast iron grates combine durability with non-stick performance
- Slide-out grease tray and ash drawer simplify cleanup
Good to know
- Assembly process has specific sequencing that can confuse builders
- Wheels work best on smooth, level surfaces
3. Captiva Designs Propane Gas Grill and Charcoal Grill Combo
Captiva Designs focuses on making the post-cook experience as smooth as the cooking process. The grease tray beneath the gas section is angled so that drippings flow directly into a hanging collection cup, while the charcoal side uses a full-length slide-out ash tray. Both systems remove completely for dumping, cutting cleanup time significantly compared to fixed pan designs. The 520-square-inch primary cooking area uses porcelain-enameled cast iron grates that distribute heat evenly across the three stainless steel burners.
Independent controls for the gas and charcoal sides mean you can run one zone at high heat and the other at a lower temperature simultaneously. The 61-inch-long cooking counter provides enough room to manage multiple dishes at once. A side burner expands your options for sauces or sides without stepping away from the main grates.
At 462.99 retail position, this is a premium mid-range option where the investment goes into material upgrades rather than raw size. The alloy steel frame is sturdy, but the unit lacks the heavy-duty wagon wheels found on larger competitors. It rolls adequately on a concrete patio but feels less stable moving over grass. For backyard cooks who value efficient cleanup and consistent heat, this model reduces the friction of dual-fuel grilling.
Why it’s great
- Grease tray tilt design channels drips directly into collection cup
- Full-size slide-out ash drawer and grease tray simplify maintenance
- Porcelain-enameled cast iron grates provide even heat distribution
Good to know
- Wheels are better suited for patios than rough terrain
- Side shelf space is adequate but not generous
4. GREEN PARTY 3 Burner Propane Gas and Charcoal Grill Combo
What sets the GREEN PARTY combo apart is the emphasis on airflow engineering. Lid-mounted dampers and an invisible front air vent allow oxygen regulation without opening the hood, which means the charcoal side can maintain a stable temperature for smoking or low-and-slow cooking with minimal heat loss. The height-adjustable charcoal pan features a crank mechanism that lets you move the coal bed closer for searing or further away for indirect roasting — a genuine temperature-tuning tool rather than a fixed grate.
The three main burners plus side burner deliver 37,000 BTU total, giving you enough power on the gas side for fast weeknight grilling. Porcelain-enameled cast iron grates cover the 685 square inches of combined cooking area, and the grease management system channels runoff into a removable cup. The ash collection tray slides out from the charcoal section, making disposal quick between sessions.
This model targets the intermediate griller who wants to experiment with temperature control techniques rather than just flipping burgers. The damper system takes some practice to dial in, but once you learn the relationship between vent position and charcoal side temperature, you can hold steady heat for hours. Assembly is typical for this category — plan on a solid afternoon with a second person.
Why it’s great
- Lid-mounted dampers and front air vent for precise temperature control
- Crank-adjustable charcoal pan for versatile coal positioning
- Dual cleanup systems — grease cup and slide-out ash tray
Good to know
- Damper system requires some learning to master
- Assembly demands several hours and two people
5. Char-Griller Dual-Function 2-Burner E5030
Char-Griller has been a steady name in the dual-fuel segment for years, and the E5030 shows why. The 24,000 BTU output from two stainless steel burners is modest compared to three-burner competitors, but the burners run the full length of the cooking chamber, distributing heat evenly across the 870 square inches of total cooking space. The porcelain-coated cast iron grates hold heat well and release food easily, and the EasyDump ash pan lets you clear out charcoal residue without tipping the entire unit.
Dual temperature gauges monitor each side independently, so you can track the gas zone and charcoal zone separately without opening the hood. Electronic ignition fires up the gas side with a button push, and the side shelf with utensil hooks provides practical prep space. The metal handle and powder-coated finish keep maintenance requirements manageable for a grill at this price tier.
This unit sits at the entry point of meaningful dual-fuel performance. The 24,000 BTU total means you won’t get the same searing intensity as higher-BTU models, but for standard grilling tasks like burgers, chicken, and vegetables, the heat output is adequate. The alloy steel frame feels sturdy for its class, though the overall build quality reflects the cost-conscious design. It is a solid starter grill for anyone new to the gas-charcoal combo format.
Why it’s great
- Full-length burners provide even heat across the gas cooking surface
- EasyDump ash pan simplifies charcoal cleanup
- Porcelain-coated cast iron grates offer good heat retention
Good to know
- 24,000 BTU output is lower than many three-burner models
- Powder-coated frame requires care to prevent chipping
6. LAUDLIFE Gas and Charcoal Grill Combo with Side Burner
LAUDLIFE emphasizes structural stability with a reinforced metal frame rated to support up to 250 pounds without wobbling. That matters when you have a loaded charcoal side, a full propane tank, and several pounds of meat spread across the grates. The 30,000 BTU total heat output comes from a three-burner gas system with piezo ignition, meaning no battery is needed to light the grill. The 748 square inches of cooking area include two warming racks that keep finished food hot while you finish the rest of the batch.
Non-stick porcelain-enameled grates cover the primary cooking surface, and the company claims they are rust-proof for long-term durability. The side burner adds additional flexibility for sauces or vegetables, and the integrated shelves and hooks keep tools and seasonings organized during cooking. The five-year customer support promise adds peace of mind for a purchase at this level.
This grill sits in the middle of the pack on cooking area and BTU output but leads on frame rigidity. If you plan to wheel the grill around frequently or cook heavy loads like multiple briskets, the reinforced chassis reduces the nervous wobble common in lighter combo units. The gas-only design recommendation against natural gas conversion is worth noting — this one runs exclusively on propane.
Why it’s great
- Reinforced frame supports up to 250 lbs without wobbling
- Piezo ignition eliminates battery dependency
- Non-stick porcelain-enameled grates simplify cleanup
Good to know
- Propane-only design; natural gas conversion not supported
- Assembly requires careful attention to frame alignment
7. Grills House ZH3005Y-SC 2-Burner Gas and Charcoal Grill Combo with Offset Smoker
The ZH3005Y-SC adds a dedicated offset smoker compartment to the standard dual-fuel format, giving you 1,020 square inches of total cooking space spread across gas, charcoal, and smoker zones. The 197-square-inch offset smoker has its own side door for adding charcoal and removing ash without opening the main chamber, which helps maintain stable smoking temperatures. Two 12,000 BTU stainless steel burners handle the gas side, while the 3-level adjustable charcoal pan lets you set coal height for searing, roasting, or smoking.
Piezo ignition fires the gas side without batteries, and dual lid-mounted thermometers let you monitor both main compartments. The warming rack adds 157 square inches for keeping food hot, and the side burner rated at 10,000 BTU expands your cooking options for sauces or sides. This is the only model in the lineup that gives you three distinct cooking zones in one chassis.
Customer reports consistently mention that the assembly instruction booklet is poorly organized — several users noted that small parts were hidden inside other compartments, causing confusion. Plan for a four-hour build with two people. Once assembled, the grill performs well for its price bracket, but the alloy steel construction and one-year warranty indicate cost-conscious engineering. It suits budget-minded cooks who want smoker capability without buying a separate rig.
Why it’s great
- Dedicated offset smoker compartment with side door for fuel access
- Three cooking zones — gas, charcoal, and smoker — in one unit
- 3-level adjustable charcoal pan for versatile heat control
Good to know
- Assembly is time-consuming and instruction manual is poorly organized
- One-year warranty is shorter than some competitors offer
8. Grills House ZH3005-SC 2-Burner Gas and Charcoal Combo Grill
The ZH3005-SC is the slightly smaller sibling of the ZH3005Y-SC, dropping the offset smoker to land at 823 square inches of cooking area across gas and charcoal sides. The 333-square-inch gas zone and 333-square-inch charcoal zone are equal, which means you get balanced capacity for both fuel types. Two 12,000 BTU stainless steel burners plus a 10,000 BTU side burner deliver 34,000 BTU total, and the piezo ignition lights the gas side without batteries.
A right-side shelf provides prep and storage space, and the lid of the side burner doubles as an additional work surface when not in use. The charcoal side features a height-adjustable pan, a smoke stack, and a side air vent for temperature control. Dual lid-mounted thermometers display temperatures for both sides independently, so you don’t need to lift the hood to check conditions.
This model targets buyers who want dual-fuel capability but don’t need the extra smoker compartment or the wider footprint of the ZH3005Y-SC. At 78.3 pounds, it is lighter than the offset-equipped version, making it easier to move around a patio. Assembly challenges mirror the larger model — the instructions are sparse, and hidden part placement frustrates builders. The one-year warranty is standard for this price range, but the overall build quality feels adequate rather than premium.
Why it’s great
- Equal 333 sq. in. gas and charcoal cooking zones for balanced use
- Piezo ignition and dual lid-mounted thermometers for convenience
- Lighter weight (78.3 lbs) for easier patio repositioning
Good to know
- Assembly process is frustrating with poorly written instructions
- One-year warranty and alloy steel build reflect entry-level construction
9. FDSAG 28-Inch Built-In Gas Grill with Charcoal Conversion
The FDSAG 28-inch built-in grill takes a different approach to dual-fuel capability — instead of separate gas and charcoal chambers, it uses a single 48,400 BTU four-burner gas system with included charcoal trays that convert the cooking surface to charcoal mode when you want smoky flavor. The 304 stainless steel construction is a significant upgrade from the alloy steel and painted steel found on most cart-style combo grills, offering superior corrosion resistance for permanent outdoor kitchen installations.
The 577 square inches of grilling space break down into 405 square inches of primary cooking area on durable cast iron grates and 182 square inches of warming rack. Built-in thermometers and illuminated control knobs make nighttime cooking easier, and the removable front grease trays slide out for straightforward cleaning. The grill can be installed as a built-in unit in an outdoor kitchen island or used freestanding on a countertop.
This is a niche product within the combo category. Rather than offering simultaneous gas and charcoal cooking, it allows you to switch between fuel types by swapping the included charcoal trays in place of the gas burner components. That means you cannot run both fuels at the same time. The price point reflects the premium stainless steel materials and the built-in form factor rather than dual-fuel versatility. It suits homeowners building a permanent outdoor kitchen who want the option to cook with charcoal occasionally without dedicating a separate appliance.
Why it’s great
- 304 stainless steel construction offers superior rust resistance for built-in use
- 48,400 BTU output delivers powerful searing capability
- Illuminated knobs and built-in thermometer enhance nighttime usability
Good to know
- Cannot grill with gas and charcoal simultaneously
- Designed primarily for built-in installation, not a mobile cart grill
