Seasoning a Cast Iron Pan
A well-seasoned pan changes color from dull grey to deep, matte black. If food is sticking or the surface looks spotty and rusted, it is time to build up the layers again.
Less is more with the oil
The most common error is using too much oil, which creates a sticky, gummy residue rather than a hard finish. Aim for a coat so thin it looks like the pan is completely dry.

- Lint-free cotton cloths or paper towels
- Oven-safe skillet
What goes in.
- 1 tspHigh smoke point oil (grapeseed, canola, or vegetable)
Baking the bond
You are not just greasing the pan; you are chemically bonding the oil to the metal through intense heat. If the oil does not reach its smoke point, it will remain liquid and eventually turn rancid.
The method.
Clean the surface
Scrub the pan thoroughly with hot water and a stiff brush to remove any previous buildup or rust. Dry it immediately on the stovetop over low heat to ensure zero moisture remains in the pores.
Apply the fat
Pour a tiny amount of oil into the pan. Use a cloth to rub it over every square inch—inside, outside, and the handle. Then, take a clean cloth and wipe the pan as if you made a mistake and are trying to remove all the oil you just applied.
Bake the pan
Place the pan upside down in a 450°F oven. Put a sheet of aluminum foil on the rack below to catch any stray drips. Bake for one hour.
Cool and repeat
Turn off the oven and let the pan cool completely inside. For a new or stripped pan, repeat this process three or four times to build a durable base.
When it doesn't go to plan.
If your pan feels sticky after cooling, you used too much oil; wipe it better next time and bake it for another 30 minutes.
Avoid using soap on a seasoned pan whenever possible, though a drop is fine if you've cooked something particularly pungent.
Always store your pan in a dry place to prevent surface flash-rust.
The ones that keep coming up.
Can I use olive oil?
Avoid extra virgin olive oil for seasoning. Its low smoke point causes it to burn and flake off before it can properly polymerize.
How do I know if it is ready?
The surface should feel smooth and look dark. Water should bead up on the surface rather than soaking into the iron.
