Sautéed onions, mushrooms, gruyere, pecorino, and half & half are whisked together with eggs, poured into a sheet pan, and baked to create these delightful and crowd-friendly sheet pan eggs.
Sauté the veggies. Melt the butter over medium heat in a large skillet. Add the onions, season with salt, and sauté until translucent. Add the mushrooms and sauté until browned and tender. Set aside.
Scramble. Crack the eggs into a large mixing bowl and add the half and half, salt, and ground black pepper. Whisk until the eggs are well beaten, and everything is combined.
Put it all together. Stir the sauteed veggies and the two cheeses into the egg mixture.
Bake. Pour the egg mixture onto the prepared sheet pan. Use a rubber spatula to spread the mixture evenly over the sheet pan if necessary. Bake for 20 minutes or until the eggs are set, and the top is golden brown.
Serve. Remove the eggs from the oven and allow them to cool for a few minutes before slicing them into squares and serving.
Add-Ins: Customize these sheet pan eggs to your liking by adding or removing ingredients. Experiment with different cheeses and mix-ins. Try fresh herbs like chives, parsley, or tarragon. Boost the veggie content with sautéed bell peppers, zucchini, spinach, or your favorite veggies. Add cooked bacon or breakfast sausage for extra protein.
Use a rimmed baking sheet to prevent spills in the oven.
Parchment paper is recommended to prevent sticking; non-stick spray or foil may not work as effectively.
Avoid over-beating the eggs, which can result in a rubbery texture.
Work quickly after whisking the eggs to maintain their light, fluffy texture.
Bake until the center sets, as overcooking can lead to toughness. Check for doneness 5 minutes before the recommended cooking time.
Storage: Cool the eggs, store them in an airtight container, and refrigerate for up to 4 days. To freeze, cut the sheet pan eggs into individual portions, and store them in an airtight container or freezer bag for up to 3 months. Thaw in the fridge before reheating.
