These baked egg cups are a quick, nutritious, and flavorful breakfast option perfect for meal prep. Packed with fresh spinach and creamy feta, they are easy to make ahead and reheat well.
If using frozen spinach, thaw and squeeze out excess water to avoid soggy cups. Do not overfill muffin cups to prevent overflow. Beating eggs well before adding fillings traps air for fluffier cups. Egg cups firm up as they cool. Variations include adding sautéed veggies, cooked sausage or bacon, or using dairy-free cheese alternatives.
