Step-by-Step Instructions
Preheat the Oven and Prepare the Pan
Set your oven to 375 F. Let it fully heat before baking so the frittata cooks evenly. Take a rimmed sheet pan and grease it well with olive oil. Make sure to coat the corners and edges so the eggs do not stick. You can also line the pan with parchment paper for easier removal.
Prepare the Ingredients
Wash and chop your vegetables into small, even pieces so they cook evenly. If using onions or mushrooms, you can cook them lightly in a pan for a few minutes to remove extra moisture. Shred the cheese if it is not pre shredded. If using cooked chicken or turkey, cut it into small bite sized pieces.
Mix the Eggs and Milk
Crack all the eggs into a large mixing bowl. Add the milk, salt, and black pepper. Use a whisk to mix everything together. Keep whisking until the mixture looks smooth and slightly foamy on top. This step helps make the sheet pan eggs light and fluffy.
Add the Fillings
Add the chopped vegetables, shredded cheese, and cooked meat into the egg mixture. Stir gently until everything is evenly mixed. Make sure the ingredients are spread throughout so every bite has a good mix of flavors.
Pour the Mixture into the Pan
Carefully pour the egg mixture into the prepared sheet pan. Use a spatula or gently tilt the pan to help spread the mixture evenly. Try to make sure the vegetables and cheese are not all in one area. Spread them out so the frittata cooks evenly.
Bake the Frittata
Place the sheet pan in the center rack of the oven. Bake for 18 to 22 minutes. The frittata is done when the center is set and does not jiggle when you gently shake the pan. The top should look lightly golden. Do not over bake, as this can make the eggs dry.
Cool Before Slicing
Remove the pan from the oven and let it rest for about 5 to 10 minutes. This helps the frittata firm up and makes it easier to cut. If you cut it too soon, it may fall apart.
Slice and Serve
Use a knife or spatula to cut the frittata into squares or rectangles. Serve warm. You can also store leftovers in the fridge and reheat later.
