Potato and Egg Breakfast Casseroles

These recipes rely on a starch base of sliced potatoes or hash browns to create a substantial meal that holds its shape when sliced. They are the traditional choice for weekend hosting because they maintain a consistent texture throughout the bake while accommodating various vegetable additions.
