How to Season a Carbon Steel Pan

Why Carbon Steel Needs Seasoning

Carbon steel pans are made of bare metal that will rust and stick without a protective seasoning layer. Seasoning — the process of baking thin layers of oil onto the surface — creates a polymerized coating that protects the metal, prevents sticking, and improves with every use. Here's how to season a carbon steel pan from scratch.

What You'll Need

• Cast iron and carbon steel seasoning oil
• Flaxseed oil (optional, for hardest seasoning)
• Paper towels
• Tongs
• Oven or stovetop
• Dish soap (for initial cleaning only)

Step 1: Remove the Factory Coating

New carbon steel pans come with a protective coating to prevent rust during shipping. Remove it by scrubbing with hot soapy water and a scrubber. Rinse thoroughly and dry completely on the stove over medium heat. This is the only time you'll use soap before seasoning.

Step 2: Apply the First Oil Layer

Once the pan is completely dry and still warm from the stove, apply a very thin layer of seasoning oil to the entire surface — interior, exterior, and handle. Use a paper towel to spread it evenly, then wipe off as much as possible. The layer should look almost invisible. Too much oil = sticky, gummy seasoning.

Oven Method (Most Even Results)

1. Place the oiled pan upside down in the oven on the middle rack
2. Put foil on the rack below to catch drips
3. Bake at 450°F (230°C) for 45–1 hour
4. Turn off oven and let cool inside
5. Repeat 3–4 times for a durable base seasoning

Stovetop Method (Faster)

1. Heat the oiled pan on the stove over medium-high heat
2. Heat until the oil smokes and stops smoking (polymerization complete)
3. Let cool slightly, apply another thin layer, heat again
4. Repeat 3–4 times

The stovetop method is faster but may season unevenly. The oven method produces more consistent results for the initial seasoning.

How to Know It's Working

After 3–4 rounds, the pan should have a dark brown to black, semi-glossy finish. It should feel smooth, not sticky. If it's sticky, you used too much oil — heat it again for another 30 minutes to finish polymerizing.

Maintaining the Seasoning

• After every use: clean with hot water and chain mail scrubber, dry on stove, wipe with thin oil layer
• Cook fatty foods regularly — bacon, steak, stir-fries all build seasoning
• Avoid cooking acidic foods (tomatoes, wine) until the seasoning is well established

Final Thoughts

Seasoning a carbon steel pan takes a couple of hours the first time but requires minimal active effort. The result is a pan that becomes more non-stick with every use — a true kitchen workhorse that improves with age.
