How to Season a Cast Iron Skillet Properly

Seasoning = baking thin layers of polymerized oil onto bare metal to create a natural non-stick coating. Most new skillets come pre-seasoned but benefit from 2-3 additional layers. Used or rusty pans need a full reset.

What You Need

• Cast iron skillet (obviously)
• High smoke-point oil (flaxseed, grapeseed, or canola — NOT olive oil)
• Paper towels or lint-free cloth
• Oven
• Aluminum foil (to catch drips)

The Process (2 hours per layer)

1. Strip old seasoning if rusty or flaking: Scrub with steel wool + dish soap until bare metal shows. Rinse and dry completely.
2. Preheat oven to 450-500°F. Place foil on bottom rack to catch drips.
3. Apply oil: Put a dime-sized amount of oil in the pan. Use a paper towel to spread it EVERYWHERE — inside, outside, handle, bottom. Then wipe it off like you're trying to remove it. The pan should look almost dry — too much oil = sticky, uneven coating.
4. Bake upside-down for 1 hour. Upside-down prevents oil pooling. You'll see smoke — that's polymerization happening.
5. Let cool in oven for 1 hour. Don't rush this.
6. Repeat 2-3 more times for a durable finish. Each layer adds protection.

Maintenance Seasoning (After Each Use)

1. Clean with hot water + stiff brush (no soap needed for daily cleaning).
2. Dry completely on stovetop over low heat (2 minutes).
3. Rub a tiny amount of oil on cooking surface while warm.

What Went Wrong

• Sticky surface: Too much oil. Strip and re-season with thinner coats.
• Flaking: Oil pooled or oven temp too low. Re-season at higher temp.
• Rust spots: Not dried properly after washing. Always heat-dry on stovetop.

Pro tip: The first 10 uses matter most. Cook fatty foods (bacon, sausage, pan-fried chicken) to accelerate seasoning. Avoid acidic foods (tomato sauce) until the seasoning is bulletproof — acid strips new layers.
