How to Re-Season a Cast-Iron Skillet in the Oven

Pale canola oil in a clear glass bowl

Re-season cast iron with an extremely thin coating of suitable oil and controlled oven heat. A thick, wet layer can create sticky patches rather than a durable cooking surface.

Clean and dry first

Remove rust or sticky residue as needed, then hand-wash and dry the skillet completely. Follow the pan manufacturer’s guidance if it has special coatings or features.

Spread a small amount of neutral oil over the pan and wipe off as much as possible with a clean cloth. The skillet should look barely oiled, not glossy with puddles.

Follow a proven heating method

Place the pan in a ventilated oven at the temperature and duration specified by the pan or oil method, using heat-safe handling. Allow it to cool safely. Repeat only if needed rather than applying thick coats.
