This Breakfast Casserole is an easy tried and true recipe from Martha with eggs, hashbrowns, sausage, and cheese. Potatoes and sausage make this a hearty breakfast. Use a hot sausage for a little kick. This is a great freezer meal.
Preheat oven to 350 degrees. Combine everything and pour mixture into a greased 9x13 pan.
Bake at 350 uncovered for 60-70 minutes until set and slightly brown on top. It can be refrigerated overnight before cooking in the morning. Serve with sour cream, salsa, or guacamole.
*This can also be made ahead and frozen (raw) and brought out for guests. When frozen cook for 1 1/2 to 2 hours. 1st hour covered 2nd hour uncovered.
Store leftover casserole in an airtight container in the fridge.
