This easy 5 ingredient Hash Brown Casserole is a versatile recipe that takes just a few minutes of prep. You can bake it right away or store it in the refrigerator overnight.
Whisk the eggs and milk in a large mixing bowl. Add salt and pepper, to taste (I use ½ teaspoon of salt and ¼ teaspoon of black pepper) then pour the egg mixture evenly over the top of the casserole ingredients.
8 eggs, 1 cup milk, salt and pepper
Sprinkle the remaining cheese over the top. Bake uncovered for 45-50 minutes, or until the eggs are set and a knife inserted comes out clean.
Notes
Make-Ahead: The casserole can be completely assembled and then covered with aluminum foil and placed in the refrigerator overnight. Set the casserole at room temperature while pre-heating the oven. It may need an additional 10-15 minutes of baking time.Variations:
To use fresh potatoes, shred about 3 medium potatoes to get 20 ounces of shredded potatoes. Place them in a bowl of water to remove the starch, then rinse them well. Repeat this process twice and pat the potatoes dry.
For an egg casserole without layers, mix the cooked sausage with all of the remaining ingredients in one bowl, reserving 1 cup of cheese. Spread the mixture into the baking dish and top with the reserved cheese.
Use southwest-style hash browns to add onions and peppers without any additional work.
Storage: Refrigerate leftovers for up to 5 days. Reheat individual portions in the microwave.To Freeze: Assemble the casserole in a freezer-safe container and wrap it tightly with heavy-duty aluminum foil for up to 3 months. Thaw in the refrigerator overnight before baking. It may need an additional 10-15 minutes of baking time.
