Best Oil For Cast Iron Cookware: Top Seasoning Oils

Cast iron is a fantastic material for cookware but needs to be seasoned with oil to keep it nonstick and rust resistant. Here are the best seasoning oils for your cast iron cookware.

Cast Iron Cooking

Cast iron is an ideal cooking material for getting the perfect sear on steaks or other proteins. Cast iron is capable of holding a large amount of heat; therefore you do not get the dreaded temperature drop when you add ingredients, like your steak, to the pan. This steady consistent heat is what makes cast iron cooking so good at producing a sear, and why it’s so desirable and popularly used to make skillets and dutch ovens.

Best Oil For Cast Iron Cooking

While cast iron is an ideal cooking material, it does need to be seasoned. Seasoning your cast iron:

  • provides a non-stick surface
  • protects against rust
  • keeps it looking nice

Cast iron does not have a perfectly smooth surface. Applying a light layer of oil fills in the gaps of the rough surface. When heated, the oil becomes hardened and binds to the cast iron, achieving a hard smooth non stick surface. Layers of seasoning can be built up to achieve additional layers of smoothness.
