How to Season a New Grill or Smoker

Why Seasoning Your Grill Matters

Every new grill and smoker arrives with manufacturing oils, metal shavings, and dust from the production and shipping process. Seasoning — running a hot burn before your first cook — eliminates these residues and creates a protective layer on metal surfaces that prevents rust and improves non-stick performance over time.

Skipping this step means your first cook may taste off (chemical or metallic flavors from manufacturing oils) and your grates and interior will be more prone to rust. Seasoning takes 45 minutes to two hours depending on your grill type, and it's a one-time investment that pays dividends for the life of your equipment.

Seasoning a Gas Grill

Step 1: Inspect and assemble. Before seasoning, verify all connections are tight, the propane tank is attached properly, and all burners light correctly. Check for gas leaks by applying soapy water to the regulator and hose connections — bubbles indicate a leak that must be fixed before proceeding.

Step 2: Initial burn. Close the lid and turn all burners to high. Let the grill run at maximum temperature for 15–20 minutes. This burns off manufacturing oils and residue from the interior and grates. You may notice some smoke and an industrial smell — this is normal and expected.

Step 3: Cool and oil. Turn off burners and let the grill cool to warm but touchable. Using a paper towel or cloth soaked in high-heat cooking oil (canola, vegetable, or flaxseed oil), wipe a thin coat of oil onto all grate surfaces. Avoid saturating — you want a thin, even film, not dripping oil.

Step 4: Second burn. Relight all burners at medium-high and let the oiled grates heat for another 15 minutes. The oil will polymerize (bond to the metal), creating the beginning of a non-stick seasoning layer. You're now ready to cook.

Seasoning a Charcoal Grill

Step 1: First burn. Load a full chimney of charcoal and let it fully ash over. Spread the hot coals across the charcoal grate, replace the cooking grate, and close the lid with all vents fully open. Let it burn at maximum temperature for 20–30 minutes.

Step 2: Oil the grates. After the initial burn, use long tongs holding an oil-soaked paper towel to coat the cooking grate with a thin layer of high-heat oil. Close the lid and let the oil smoke for another 10 minutes.

Step 3: Ongoing seasoning. Charcoal grill grates — especially cast iron — continue building seasoning with every cook. After each use, brush the hot grates clean and apply a light oil wipe. This ongoing process creates a progressively better non-stick surface.

Seasoning a Pellet Grill

Most pellet grill manufacturers include a specific initial burn-in procedure in the manual. The general process involves filling the hopper with pellets, running the startup sequence, and holding the grill at a set temperature (usually 350–400°F) for 30–45 minutes.

Follow your specific model's instructions rather than a generic procedure — pellet grills have different auger priming requirements, ignition sequences, and burn-in temperatures. After the manufacturer's burn-in, you can oil the grates using the same method described for gas grills.

Seasoning an Offset Smoker

Offset smokers benefit from a more thorough seasoning process because they have larger interior surfaces exposed to the elements.

Step 1: Wash the interior. Wipe down the cooking chamber and grates with warm soapy water to remove manufacturing grease and debris. Rinse thoroughly and dry completely.

Step 2: Oil all interior surfaces. Using a spray bottle or cloth, apply a thin coat of cooking oil to every interior surface — chamber walls, lid interior, grates, and the firebox interior. This creates a base layer of rust protection.

Step 3: Run a seasoning fire. Build a small fire in the firebox using charcoal and a couple of wood chunks. Bring the cooking chamber to 250–275°F and hold it there for 2–3 hours. The oil will bake into the metal, creating a sealed surface. Add fuel as needed to maintain temperature.

Step 4: Let it cool naturally. Allow the smoker to cool completely before closing all vents and covering it. The interior should have a slightly darkened, matte appearance — this is the seasoning layer that protects against rust and improves smoke adhesion over time.

Maintaining Your Seasoning

Seasoning is not a one-time event — it builds and improves with every cook. After each session, brush the hot grates clean while they're still warm, apply a light oil wipe, and let them cool. Avoid using soap on cast iron grates, as it can strip the seasoning layer.

If you notice rust developing on grates or interior surfaces, scrub the affected area with steel wool, re-oil, and run a hot burn to re-establish the seasoning. Catching rust early is important — once it penetrates deeply into the metal, the surface becomes pitted and harder to maintain.

For grills stored outdoors, a quality cover is your first line of defense against moisture that causes rust. Even well-seasoned surfaces will eventually rust if continuously exposed to rain and humidity without protection.
