If you love potatoes, this casserole is for you. Crispy hash browns, melted cheddar cheese, and eggs come together in this comforting dish that tastes like a classic diner breakfast — but baked in one pan.
You can use frozen hash browns for convenience or shred your own potatoes for a rustic feel. Add some crumbled bacon or green onions for an extra kick of flavor. It’s rich, hearty, and guaranteed to make mornings better.
3. Ham, Egg, and Cheese Croissant Casserole
