Cast Iron Cookware FAQ

Seasoning cast iron involves coating it with a thin layer of oil and baking it at a high temperature to create a non-stick surface. Wash and dry your pan, spread a thin layer of vegetable oil or shortening over the surface, and bake it upside down in a preheated oven at 375-400°F (190-204°C) for an hour. Allow it to cool in the oven.

It’s not recommended to put cast iron cookware in the dishwasher. The harsh detergents and soaking can strip the seasoning off your cookware. It’s best to wash cast iron by hand with warm water and, if necessary, a small amount of soap.

Rust is not dangerous, but it can make food taste metallic and can continue to degrade the cookware if not treated. Rust can typically be removed with a little bit of steel wool or a stiff brush and then re-season the cookware after drying it completely.

Cooking highly acidic foods like tomatoes in newly seasoned cast iron can strip the seasoning due to the acids reacting with the iron. Once your cookware is well-seasoned through multiple uses, this becomes less of a problem. For fresh seasoning, limit the cooking time for acidic foods.

A sticky surface usually indicates excess oil was left on the pan during the seasoning process. To fix this, bake the cookware for longer or at a higher temperature to fully polymerize the oil. Ensure to use a very thin layer of oil when seasoning.

Store your cast iron in a dry place. If stacking pans, place a paper towel between them to absorb moisture and prevent scratches. Ensure they’re fully dry to prevent rust formation.

Food sticking can be due to insufficient seasoning or the pan not being adequately preheated. Ensure your pan has a good layer of seasoning, and always preheat it before adding food for the best non-stick performance.

Wash and scrub the cookware to remove rust and debris. Dry thoroughly, apply a thin coat of oil, and bake upside down in the oven at 375-400°F (190-204°C) for an hour. Allow it to cool in the oven. Repeat as necessary.

Beyond avoiding prolonged cooking of acidic foods in a freshly-seasoned pan, cast iron is versatile. However, cooking strong-smelling foods (e.g., fish) might leave lingering odors that could transfer to other foods. Regular cleaning and maintenance mitigate this issue.

Yes, metal utensils can be used on cast iron, but be mindful not to gouge or scrape the pan aggressively. Wooden, silicone, or plastic utensils are gentler on the pan’s seasoning, especially for newer cookware.
