if I'm making a frittata with my cast iron skillet will it stick? I don't have any nonstick ovenproof pans.
If it is perfectly seasoned, it prob won't stick, but just in case, use extra oil or butter
Why not line it with parchment paper?
I wouldn't think of using a non-stick pan. The cast iron skillet works perfectly. I melt some butter or coat the bottom of the pan with olive oil before I add the egg mixture and the frittata comes out perfectly, golden brown.
Butter is your friend - if you use parchment, make sure to butter that too.
