A hearty, slow-cooked breakfast casserole packed with fluffy eggs, melted cheddar cheese, tender potatoes, and aromatic vegetables. This set-and-forget dish delivers a golden, custardy texture with a savory, satisfying flavor perfect for leisurely mornings.
Storage: Refrigerate leftovers in an airtight container for up to 4 days. To reheat, microwave individual portions on high for 1-2 minutes, or in a 350°F (177°C) oven for 10-15 minutes. Freezing: This casserole freezes well for up to 3 months. Cool completely, wrap tightly in plastic wrap and foil, then thaw overnight in the fridge before reheating. For a larger crowd, double the recipe and use a 6-quart slow cooker, increasing cook time to 5-6 hours on LOW.
