Typically our frittata recipes call for using an oven-safe nonstick skillet. If you aren’t sure about putting your skillet in the oven, use the following modification: follow the recipe until it calls for adding beaten eggs to the skillet. Instead, add the ingredients from the skillet into the mixing bowl with your egg mixture. Stir quickly to combine, and transfer everything into a parchment lined baking pan (example pictured below). Bake in a 375 degree oven for 10 minutes or until puffed in the center and slightly golden at the edges.
