For an extra layer of flavor, consider adding a clove of minced garlic to the skillet along with the mushrooms. Ensure your skillet is truly oven-safe before placing it in the oven. If unsure, use a cast-iron skillet. To prevent the frittata from sticking, you can lightly grease the skillet before adding the butter. Feel free to substitute the mozzarella and Parmesan with other cheeses you enjoy, such as Gruyere or Fontina. Allowing the frittata to cool slightly before slicing helps it hold its shape better.
