My spinach feta egg bake is a delicious high-protein breakfast! Made with just spinach, egg whites, feta cheese, salt, and pepper, it’s the perfect healthy meal prep recipe to make in advance to ensure you’re getting a good amount of protein with your morning meal.
Preheat the oven to 350 degrees F. Line an 8″x8″ baking dish with parchment paper, and add a little olive oil on the parchment to prevent sticking (or use cooking spray).
Add the chopped spinach to the prepared baking dish. Pour the egg whites over the spinach, then add the salt and pepper. Stir the seasoning into the egg whites.
Sprinkle the feta cheese over the top of the egg mixture. Bake for 30-35 minutes, or until the egg whites are fully cooked. Allow cooling for 10 minutes before cutting into pieces.
