Can You Use Charcoal in a Gas Grill?
The short answer is usually no — but the reason matters, and a purpose-built dual-fuel grill is a different case. Here's what to know.
What can go wrong
- Blocked burners: Charcoal dust and ash can plug gas burner ports, which risks incomplete combustion and a buildup of gas — an explosion hazard.
- Heat damage: Burning charcoal can get hotter than a gas grill is built to handle, and may damage burners, gas lines, or the grill body.
- Falling embers: Many gas grills have openings in the bottom of the cooking box, so embers can drop out.
- Warranty: Using charcoal in a gas grill can void the manufacturer's warranty. Check yours.
- Carbon monoxide: Charcoal produces CO until it's fully extinguished, so always keep the grill outdoors in a well-ventilated space.
Some sources phrase these as absolute. They're written here as risks because that's the accurate framing.
Safer ways to add smoky flavor to a gas grill
- Smoker box or tube with wood chips: designed to sit on or above the burners and produce smoke.
- A manufacturer's charcoal tray for your model: some makers sell a tray that replaces the grates and holds charcoal above the burners. Use only the accessory made for your specific grill, and follow its instructions.
- A separate charcoal grill: simple, and no risk to your gas grill.
How purpose-built dual-fuel grills are different
A dual-fuel grill is engineered with charcoal use in mind. Typically that means a dedicated charcoal tray or chamber, designed airflow, and materials chosen for the heat. Some models use a drop-in tray that sits above the gas burners; others separate the two fuels. The key point: follow the manufacturer's instructions for that exact model. What is safe for one grill may not be safe for another.
FoldSear is built as a dual-fuel design — you add the charcoal tray to cook with charcoal, or remove it to cook on gas. See how the gas and charcoal modes work. The exact steps for lighting charcoal, switching modes, and protecting the gas parts are set by the manual and confirmed with the factory, so this guide keeps to the general principle rather than FoldSear-specific instructions.
General safety when cooking with charcoal
- Use outdoors only, never in a garage, tent, vehicle, or under a surface that can burn.
- Don't use lighter fluid on hot or warm coals, and never use gasoline or similar fuels.
- Use a charcoal chimney or another approved starter when possible.
- Let coals burn out completely and ashes cool for at least 48 hours before disposal.
- If a grill uses both gas and charcoal, follow the manual about shutting off the gas when lighting or using charcoal — some designs require the gas fully off once the charcoal is lit.
- Keep grills at least 10 feet from your house or shed.
Which setup
How to choose
| If you want | Consider |
|---|---|
| Fast, easy cooking | A gas grill |
| Mostly smoky flavor | A charcoal grill |
| A hint of smoke on gas | A smoker box with wood chips |
| Both fuels in one unit | A purpose-built dual-fuel grill, used per its manual |
FAQ
Charcoal in a gas grill questions
Can I put charcoal directly on the burners of my gas grill?
No. It can block burners, damage the grill, and create safety hazards. Charcoal belongs in a grill designed for it.
Can I use a charcoal tray in my gas grill?
Only if the manufacturer makes one for your specific model. Follow its instructions, and don't improvise a tray or holder.
What is a dual-fuel grill?
A grill designed to run on both gas and charcoal, usually through a dedicated charcoal tray or section, following the manual for that model.
Does FoldSear use gas and charcoal at the same time?
FoldSear is designed to run in gas mode or charcoal mode. See the manual for the exact steps and safety details.
Is it safe to light charcoal with gas burners?
Only if the grill's manual says so. Some designs do this; others don't. For FoldSear, follow the manual rather than assuming a method.
How do I get charcoal flavor on a gas grill?
Use a smoker box with wood chips, or cook on a grill designed for charcoal. Both add smoky flavor without putting charcoal in a gas-only grill.
