Just bought a new gas grill? Before you start cooking, it’s important to season your grill. Seasoning isn’t just for cast iron pans—it’s a key step to protect your grates, prevent food from sticking, and ensure every meal tastes great. Here’s how to season a gas grill the right way, whether you have cast iron, porcelain, or stainless steel grates.
Why Season a Gas Grill?
- Burns off manufacturing oils: Removes residues from the factory, packaging, and shipping.
- Protects your grates: Adds a thin layer of oil that helps prevent rust and corrosion.
- Keeps food from sticking: Seasoned grates make it easier to flip burgers, fish, and more.
- Improves flavor: Creates a surface that helps develop a tasty sear on your food.
What You’ll Need
- High-heat cooking oil (canola, grapeseed, peanut, or vegetable oil)
- Paper towels or a clean cloth
- Long-handled tongs
- Soap and water (for the initial cleaning)
Step-by-Step: Seasoning Your Gas Grill for the First Time
Step 1: Wash and Rinse the Grates
- Remove the cooking grates and wash them with warm, soapy water to get rid of factory residue and dust.
- Rinse thoroughly and dry completely with a towel or let them air dry.
Step 2: Coat the Grates with Oil
- Pour a small amount of high-heat oil onto a folded paper towel or cloth.
- Use tongs to rub the oil all over the top and bottom of the grates, covering every surface lightly (don’t drench them—just a thin layer).
- Tip: Avoid using butter, olive oil, or nonstick sprays—they have lower smoke points and can get sticky.
Step 3: Reassemble and Fire Up the Grill
- Put the grates back in place and make sure everything is set up according to your grill’s manual.
- Close the lid and turn all burners to high. Let the grill heat up for 15–20 minutes.
- You’ll see smoke as the oil bonds to the metal—this is normal and part of the seasoning process.
Step 4: Cool Down and Repeat (Optional)
- After 20 minutes, turn off the burners and let the grill cool with the lid closed.
- For extra protection (especially for cast iron grates), repeat the oiling and heating process once more.
After Seasoning: First Use Tips
- Brush the grates lightly before and after each cook with a grill brush.
- Before grilling, lightly oil the grates or your food to maintain a slick, nonstick surface.
- Keep your grill covered when not in use to protect the seasoned surface and prevent rust.
- No need to wash with soap after every use—just brush off food bits and wipe with oil if needed.
Frequently Asked Questions
Do I need to season porcelain or stainless steel grates?
Yes! Even porcelain or stainless grates benefit from a light seasoning to prevent sticking and add protection. Just avoid metal scrapers on porcelain to keep the coating intact.
What oil is best for seasoning a gas grill?
Use high-smoke point oils like canola, grapeseed, vegetable, or peanut oil. Avoid olive oil and butter, which can burn or get gummy.
How often should I re-season my grill?
For best results, reapply a thin coat of oil every few cooks or whenever grates start looking dry or rusty.
Can I season the grill with the burners off?
No—the oil needs high heat to bond to the metal. Always heat the grill after oiling.
Conclusion: Start Every Grill Season Right
Taking just 30 minutes to season your new gas grill sets you up for a lifetime of nonstick cooking, rust protection, and better-tasting food. Don’t skip this easy step! With regular care and a little oil, your grill will deliver great results season after season.
