Every pellet grill manual has a page most owners skip straight past on the way to the first cook — the seasoning, or burn-in, step. Skipping it doesn’t just risk an off-tasting first meal; it’s also the one dry run every component gets before you trust the grill with a $60 brisket.
Quick Answer
Seasoning a new pellet grill means running it empty at high heat for 15-90 minutes (brand-dependent) to burn off manufacturing oil and cure the interior finish before the first real cook. Traeger’s own WiFIRE instructions call for 350°F for 20 minutes, then 450-500°F for 30 minutes (about 90 minutes total); Pit Boss’s own guide calls for oiling the grates, then 375°F for roughly 15 minutes. Every brand’s process differs slightly, so check your model’s manual first — but the underlying goal is the same everywhere: burn off the factory oil, cure the coating, and confirm the auger, igniter, and fan all work before food is involved.
Why seasoning matters — it’s not just tradition
Manufacturers coat the interior metal of a new pellet grill in a food-grade mineral oil during production specifically to prevent rust during shipping and warehouse storage, according to PelHeat’s rundown of the process. That oil has to burn off before the grill is used for cooking, or it can transfer a metallic, chemical off-taste to the first thing you cook. The same high-heat cycle also cures the powder-coat paint on the interior surfaces, which is what actually gives new pellet grills their long-term rust resistance — and it doubles as a real functional test of the auger, igniter, and fan before you’re relying on all three for an overnight brisket.
Burn-in temperature and time by brand
Manufacturers don’t agree on one universal number, so check your own model’s manual against this table before you start:
| Brand | Stage 1 | Stage 2 | Total time |
|---|---|---|---|
| Traeger (WiFIRE models) | 350°F — 20 min | 450-500°F — 30 min | ~90 min |
| Traeger (non-WiFi models) | 400-450°F — 30 min | — | ~30-40 min |
| Pit Boss | Oil grates + Flame Broiler Plate, then 375°F | — | ~15 min |
| RecTeq | 400°F | — | ~60 min |
| Grilla Grills | 450°F | — | ~45 min |
If your brand isn’t on this list — Camp Chef, Z Grills, Green Mountain, Weber, and several others don’t publish a single definitive burn-in number the way Traeger and Pit Boss do — the safe default that matches the pattern above is to run the empty grill at 400-450°F for 30-45 minutes with the lid closed, after first lightly oiling the grates and any interior plate with a high smoke-point oil. That’s not a substitute for your specific manual, but it lands inside the range every published brand process above actually uses.
The general process, step by step
- Do this before anything else touches the grates. Seasoning happens before the first cook, not after — mixing manufacturing oil with your first batch of food-grade oil defeats the point.
- Oil the grates and any interior plate. Pit Boss’s own instructions specifically call for a liberal coat of canola, peanut, or coconut oil worked into the grates and Flame Broiler Plate — a paper towel with spray oil, or a basting brush, both work. Skip olive oil; its lower smoke point and strong flavor aren’t suited to a high-heat burn.
- Run your startup sequence as normal, then bring the grill up to your brand’s specified temperature (see the table above).
- Hold that temperature for the full duration, lid closed, with nothing on the grates. This is also your chance to catch a dead igniter or an auger jam before real food is at stake.
- Let it cool completely before the first real cook. Once it’s cooled, the grill is seasoned and ready — no further prep needed before you load up your first rack of ribs or a full brisket.
High smoke-point spray oil for seasoning and cooking
- A neutral, high smoke-point oil avoids the burnt/bitter flavor olive oil can leave behind at burn-in temperatures.
- A pump or trigger spray gives more even, controlled coverage across grates and plates than pouring straight from the bottle.
- One bottle covers the initial burn-in and routine grate maintenance for a full season.

What a skipped seasoning step actually costs you
The two real risks aren’t hypothetical. First, an off-taste: leftover manufacturing oil burning directly onto your first meal instead of burning off empty beforehand. Second, a missed shakedown: the burn-in cycle is the only time the auger, igniter, and fan all run together under real heat with nothing riding on it — the same components covered in our pellet grill maintenance and troubleshooting guide when they fail mid-cook later. Catching a dead igniter or a jammed auger during a 15-90 minute empty burn beats discovering it three hours into an overnight brisket.
Once the burn-in is done, the ongoing upkeep is a different routine entirely — see our how to clean a pellet grill guide for the deep-clean cadence, and our best pellet grill accessories roundup for the tools worth keeping on hand beyond the seasoning oil.
FAQ
Do you really need to season a pellet grill before the first cook? Yes — every major manufacturer’s manual requires it. It burns off factory-applied rust-prevention oil, cures the powder-coat finish, and tests the auger, igniter, and fan before food is involved.
What temperature do you season a Traeger at? WiFIRE models: 350°F for 20 minutes, then 450-500°F for 30 minutes (~90 min total), per Traeger’s own support article. Non-WiFi models: 400-450°F for 30 minutes once at temperature.
How long do you season a Pit Boss pellet grill? Oil the grates and Flame Broiler Plate with a high-heat oil, then run at 375°F for about 15 minutes, per Pit Boss’s own guide.
What oil should I use to season a pellet grill? A high smoke-point oil — canola, peanut, avocado, or coconut. Skip olive oil; Pit Boss’s own instructions specifically call out its low smoke point and strong flavor as a poor fit.
What happens if you skip seasoning on a brand-new pellet grill? Manufacturing oil can transfer an off-taste to your first cook, and you lose the only full-system test of the auger, igniter, and fan before real food is on the line.
