My mom always made this simple cheddar egg bake alongside our favorite coffee cake on Christmas morning. It’s an easy, crowd-pleasing dish that’s perfect for feeding a large group—make it for holiday brunch or any weekend gathering.
Sharp cheddar and a surprising touch of mustard give this bake a savory boost that guests always ask about. Mix it up as you wake up and it will be ready to serve by the time others are ready to eat.
