Should an enameled cast iron pan be seasoned?
Short answer: No, you cannot season enameled cast iron cookware.

Enamel does not take seasoning in the same sense as cast iron or carbon steel. 

I don't know if seasoning would *hurt" the pan, but I've never heard of anyone seasoning their enamel cookware. So if you do try it though, let us know how it goes.

If you’re gonna season, just buy cast iron and save a lot of money.
