Compare bbq combo grills by fuel pairing, cooking area, heat control, grates and cleanup, with a clear checklist for patios, balconies and family cookouts.
A combo grill promises two ways to cook in one footprint, but that promise only helps if both sides match how you cook each week. The best bbq combo grills pair a fast side for weeknight dinners with a slower side for smoke flavor, without wasting patio space. Use the product table to compare fuel pairings, size and controls.
Start by naming your two most common cooks. If one is burgers on a Tuesday and the other is ribs on a Saturday, your pairing is already taking shape. The sections below match buyer groups to fuel, area, heat control, build and cleanup.
Who Should Buy Which BBQ Combo Grill?
Pick by the cook you repeat most often, then check that the second side serves a real second job. A half unused combo costs more and takes longer to clean than a single fuel grill.
Backyard Hosts Who Cook for Groups
You cook for eight or more people and need food to finish in waves. Choose a large pairing where one side sears while the other holds food warm. About 600 to 800 square inches gives room for burgers, corn and vegetables without constant shuffling. Two temperature zones matter more than compact size.
Flavor Focused Cooks Who Want Smoke and Sear
You care about bark on a brisket and a dark crust on a steak from one unit. Look for a charcoal or pellet side that holds low heat for hours, paired with a gas side that heats fast for finishing. Cast iron grates help with sear marks, and a tight fitting lid keeps smoke around food.
Small Patio Cooks With Limited Space
You have a narrow patio and every inch counts. Choose a compact pairing with fold down shelves and a footprint you have measured, not guessed. About 400 to 550 square inches still handles dinner for four if the layout is simple. Check local rules and your lease first, because some buildings limit fuel types outdoors.
Key Features to Compare
Compare these factors in order, because fuel and size decide most of your experience. When you compare best bbq combo grills side by side, note the fuel pairing, the area of each side and the control type for each model. That list stops a small extra from hiding a poor pairing.
Fuel Pairing and How Each Side Works
Fuel pairing is the heart of a combo grill. Gas heats in minutes and suits quick dinners, charcoal takes longer but gives deeper smoke flavor, and pellets feed fuel on their own for steadier low heat. Electric sides need an outlet and give the least smoke flavor. Running costs differ too, since propane and pellets are bought again and again. Choose the pairing around your two main cooks, not a rare holiday meal.
Cooking Area and Capacity
Cooking area is listed in square inches, but the split between sides matters more than the total. A family of four usually needs about 400 to 550 square inches in total, while regular hosts should look closer to 600 to 800 square inches. About 100 square inches holds roughly eight burgers. Check the warming rack separately, and confirm both lids can hold tall food such as whole chickens.
Temperature Control and Heat Output
Heat output for gas burners is shown in BTU, and a higher number helps the grill recover heat after you lift the lid, though it does not guarantee even heat. Look for separate controls for each side and, on pellet sides, a PID controller that adjusts fuel feed to hold a set temperature. For low and slow cooking you need a side that stays near 225 to 250 degrees for hours.
Build Quality and Grate Materials
A combo body takes heat from two sources, so material and thickness matter for lifespan. Thicker steel holds heat more evenly, while stainless steel grade 304 resists rust better than thinner painted steel. Cast iron grates hold heat well and leave strong sear marks, but they need seasoning and prompt drying. Porcelain coated steel grates clean more easily, yet the coating can chip if you scrape it with sharp tools.
Cleanup, Assembly and Warranty
Two fuel sides mean two cleanup jobs, so look for a removable ash pan on the charcoal side and a slide out grease tray on the gas or pellet side. A pellet hopper that empties easily helps you change pellet type and store fuel dry. Assembly often takes about one to two hours with two people. Compare warranty length for burners, grates and the firebox separately. Also check the full footprint with shelves up before you order.
Types of BBQ Combo Grills Compared
Combo grills differ mainly in which two cooking methods share one frame. If you only need one method, see our guide to the best bbq grills for single fuel options.
Gas and Charcoal Side by Side Units
This is the most common pairing, with gas on one side and charcoal on the other. You get weeknight speed plus weekend charcoal flavor. It suits mixed households where cooks disagree about fuel. The trade off is size, since two chambers make these units among the widest you can buy.
Pellet and Gas Combination Units
A pellet side gives set and hold smoking with a hopper and automatic feed, while the gas side covers fast grilling and searing. It suits cooks who want smoke flavor without tending a fire. If pellet cooking is your main interest, see our guide to the best pellet bbq grills. Pellet sides need power and dry fuel storage.
Charcoal Grill and Offset Smoker Combinations
The main chamber grills over charcoal and a smaller side firebox feeds smoke through for low and slow cuts such as ribs and pork shoulder. Flavor is the strong point. The cost is attention, since you add fuel and adjust vents during long cooks. For more on smoking pairings, see our guide to the best bbq grills and smokers.
Compact Pairings for Small Patios
Smaller combos pair a modest gas section with a compact charcoal section, or use one chamber with two fuel trays. They fit small decks where a full size unit would block a door. Capacity is limited, so you cook in batches. If propane alone fits better, see our guide to the best bbq grills propane.
Common Mistakes to Avoid
These errors often show up after the first few cooks, when returning a large grill is hardest.
- Buying the widest combo without measuring your gate leaves you with a grill that cannot reach its spot.
- Choosing a pairing for rare feasts means the second side sits unused while still needing cleaning and cover space.
- Judging size by total area alone hides a lopsided split where the side you use most is too small.
- Ignoring grease and ash access makes cleanup slow, so residue builds up and smoke flavor turns bitter.
- Placing a combo grill against a wall traps heat and can damage siding or the lid finish.
Care and Maintenance for Your Combo Grill
Preheat the grill for about 10 to 15 minutes, then brush the grates while warm and wipe them lightly with oil on a cloth. Empty the ash pan only after ash is fully cold, and clear the grease tray before it overflows. Once dry and cool, close the vents and put on a cover.
Each season, check gas hoses with soapy water and watch for bubbles that signal a leak, and replace cracked hoses before use. If you smell gas and cannot find the source, turn off the supply and contact a qualified technician instead of lighting the grill. Dry cast iron grates fully and coat them with a thin layer of oil. Store pellets dry, because damp pellets can jam the feed.
FAQ
How big of a BBQ combo grill do I need for a family cookout?
A BBQ combo grill with about 400 to 550 total square inches usually suits a family of four for a single cookout. Count both sides only if you will use both at once. For parties, cook in batches on the hot side while the other side keeps food warm.
Is a pellet hopper worth it on a BBQ combo grill?
A pellet hopper is worth it on a BBQ combo grill if you smoke at least once or twice a month. The hopper feeds pellets on its own, so long cooks need fewer checks. A larger hopper of about 15 to 20 pounds can cover an overnight cook without a refill, a detail many buyers miss.
What fuel pairing gives the strongest smoke flavor on a BBQ combo grill?
A charcoal and offset smoker pairing gives the strongest smoke flavor on a BBQ combo grill. Wood chunks added to charcoal deepen that flavor more than pellets alone do. On a pellet side, cook low for the first hour, when meat takes on smoke most readily, then raise the heat to finish.
How long should a good BBQ combo grill last with regular care?
A good BBQ combo grill should last about five to ten years with regular care and covered storage. Burners, igniters and grates usually need replacement first, so check that spares are sold before you buy. Keeping the grill off wet ground slows rust on the lower frame.
Can I use a BBQ combo grill on an apartment balcony?
You can use a BBQ combo grill on an apartment balcony only if your lease, building rules and local fire code allow that fuel type there. Many buildings ban charcoal on balconies, and some limit fuel storage. Keep a clear exit path, follow the safe distance from railings in your rules and never store a spare propane tank indoors.
Final Thoughts
Choose the pairing first, then confirm that each side is large enough and cleanup is simple enough to repeat weekly. Use the product table to compare fuel, split area and controls against your patio measurement and budget.
When you judge best bbq combo grills by how you cook on a normal week, the right pairing becomes clear. Buy the smallest combo that serves both regular cooks well, and you will use both sides often. For a narrower shortlist, see our guide to the best combo grills as a related comparison.
