How to Season a Carbon Steel Pan (Step by Step)

Seasoning is what turns a raw carbon steel pan into a naturally nonstick, rust-proof workhorse. It sounds intimidating, but it is just oil and heat - about 20 minutes of work. Here is exactly how.

What seasoning is (and why it matters)

Seasoning is a thin layer of oil baked onto the steel until it polymerizes into a hard, slick coating. That layer gives carbon steel its natural release and protects it from rust. The more you cook, the darker and more nonstick it gets.

Step 1: Strip the factory coating

New carbon steel pans ship with a protective wax or lacquer. Scrub it off with hot water, dish soap, and a stiff brush, then dry thoroughly over low heat. This is the only time you will use soap heavily.

Step 2: Season with oil and heat

1. Set the dry pan on medium heat for a minute, then add a small amount of high-smoke-point oil (grapeseed, flaxseed, or canola).
2. Rub the oil over the entire surface with a paper towel - then wipe it back off so only a microscopically thin film remains. Too much oil turns sticky.
3. Heat until the oil smokes and the surface darkens, about 3-5 minutes; let it cool slightly.
4. Repeat 3-5 times. The pan shifts from silver to bronze to brown - that is the seasoning building.

Prefer the oven? Oil, wipe off, then bake upside down at 450F for an hour.

Step 3: Cook to keep it building

The best seasoning comes from cooking. Fry, sear, and saute with a little fat and the patina deepens with every use. Avoid simmering acidic foods (tomato, wine) early on - they can strip young seasoning.

How to maintain it

• Clean with hot water and a brush - skip soap and the dishwasher.
• Dry immediately and fully (rust forms on wet steel).
• Wipe a tiny bit of oil over the surface before storing.

Frequently asked questions

What oil is best for seasoning? A high-smoke-point oil - grapeseed, flaxseed, or canola.
How many times should I season? 3-5 coats to start; it deepens as you cook.
Do you season carbon steel like cast iron? Yes - the process is the same.

Alva carbon steel has no nonstick coating - no PFAS or PTFE by design - safety standards.
