How to Prepare & Season a Charcoal Grill – Beginner & Advanced Tips

Clear out old ash to maximize airflow and help coals burn hotter.

Start with clean grates so food doesn't stick and flavors stay fresh.

Use the right amount of charcoal based on whether you're searing or doing a quick cook.

Open the vents fully while getting the fire going to help coals ignite faster.

Preheat with the lid on to stabilize and maintain your target temperature.

WARNING: CARBON MONOXIDE HAZARD Burning charcoal inside can kill you. It gives off carbon monoxide, which has no odor. NEVER burn charcoal inside homes, vehicles or tents.

Never use gasoline to light charcoal.

Do not add lighter fluid directly to burning or hot charcoal.

Make sure ashes are cold before discarding.

Barbecue away from flammable items, overhangs and trees.

Store charcoal briquet in a cool, dry place.

Dispose of ash safely in a metal container, as embers can stay hot long after cooking.

Clean grates carefully to prevent slips or injuries while brushing the surface.

Handle grates with gloves if they're warm to avoid accidental burns.

Check that vents are clear and adjust them only when the grill is stable and safe to access.

Reinstall grates securely so they don't shift when arranging charcoal or placing food.

Assemble and clean: Wipe down the grates and inside surfaces to remove dust or residue.

Coat the grates with oil: Use a high-heat oil like canola or grapeseed; apply a thin layer using a paper towel or brush.

Add charcoal and ignite: Use a chimney or lighter fluid to start a medium-hot fire.

Heat grill to 400–450°F: Keep the lid on and vents open.

Let it run for 30–40 minutes: The oil will polymerize onto the grates, creating a protective, nonstick coating.

Cool and re-oil lightly: After cooling, apply another very thin layer of oil to maintain seasoning.

This only needs to be done once, but re-oiling grates occasionally helps maintain the coating.

Empty old ash:

• Remove leftover cooled ash inside the grill to improve airflow and help charcoal burn hotter.
• Clear the ash catcher or tray so vents stay unobstructed.
• Dump ash into a metal bin once the grill is completely cool.

Clean grates:

• Brush off food debris to prevent sticking and off-flavors.
• Scrape cold grates first, then brush again once they warm up.
• Ensure the grate surface is smooth and ready for cooking.

Check vent positions:

• Make sure bottom vents are open and free of ash or debris.
• Confirm top vents move easily and aren't blocked.
• Adjust vents later to control heat, but keep them open when starting the grill.

Place or reinstall the charcoal grate (if removed):

• Set the charcoal grate securely into position before adding coals.
• Ensure it sits level so heat distributes evenly.
• Check for stability so briquets or lump charcoal don't shift.

Oil the cooking grate:

• Apply a thin coat of high-heat oil to help prevent food from sticking.
• Use a paper towel or brush to avoid buildup or dripping.
• Carefully reapply lightly after preheating using heat gloves if you prefer oiling hot grates.

How you arrange your charcoal sets the foundation for consistent heat and better cooking results. From creating a hot direct zone for searing to setting up indirect heat for thicker cuts, the right coal layout helps you control temperature and cook more efficiently.
