Season a Cast Iron Skillet the Right Way

The biggest mistake people make: using too much oil. A thin, almost-invisible layer of oil is what polymerizes into a hard, non-stick coating — a thick coat turns sticky and gummy. Seasoning is just baked-on polymerized oil, and each layer adds to the protection.

What You Need

• Oil with a high smoke point: Flaxseed, Crisco shortening, or grapeseed oil are top picks. Avoid olive oil — it smokes too low and goes rancid.
• Your oven (must reach 450–500°F / 230–260°C)
• Lint-free cloth or paper towels

Step-by-Step Process

1. Wash the skillet with warm soapy water and a stiff brush. Yes, soap is fine this one time — you're starting fresh. Rinse thoroughly.
2. Dry completely — put it on the stove over medium heat for 2–3 minutes until all moisture evaporates. Water is the enemy of cast iron.
3. Apply a tiny amount of oil all over: inside, outside, handle, bottom. Then wipe it all back off with a clean cloth until it looks like there's barely any oil left. This is the key step most people skip.
4. Place upside down in a preheated 450–500°F oven with a sheet of foil on the rack below to catch drips.
5. Bake for 1 hour, then turn the oven off and let the skillet cool inside the oven completely. Do not rush this.
6. Repeat 3–4 times for a solid base layer. Each round deepens and strengthens the seasoning.

Ongoing Maintenance

• After each cook, wipe it out while warm, rinse with hot water, dry on the stove over heat, and apply a micro-thin layer of oil before storing.
• Cooking bacon, sausage, or any fatty protein adds seasoning naturally over time.
• Avoid acidic foods (tomatoes, lemon, wine) until the seasoning is well established — acid strips the coating.
• If rust appears, scrub it off with steel wool, re-wash, and re-season from scratch.

Pro tip: The oven method is the proper way to season, but the single fastest way to build seasoning day-to-day is simply to cook with it. Fry potatoes or bacon a few times and you'll add more seasoning than any oven session. The skillet gets better the more you use it.
