Frittata with Red Onions
Frittata is most easily served right out of the pan. Simply slice with a rubber spatula or pie server, being careful not to damage the pan.
If you want to turn the frittata out onto a cutting board, be sure to run a rubber spatula along the edges and gently under the center to release first.
Gruyere, Cheddar, gouda, and Manchego are all great cheese substitutes for this frittata.
Using a sweet bacon will cause sugar to stick to the pan and interfere with the frittata releasing after cooking.
