A savory and comforting winter breakfast casserole featuring flavorful beef sausage, crispy hash browns, fluffy eggs, and melted cheddar cheese, baked together to create a hearty and satisfying meal perfect for chilly mornings.
Cook the Beef Sausage: Brown the beef sausage in a large skillet over medium-high heat until fully cooked and crumbled. Drain off excess grease and set aside.
Prepare the Baking Dish: Preheat the oven to 375°F (190°C). Spread the thawed shredded hash browns evenly in the bottom of a 9×13 inch baking dish. Scatter the browned beef sausage over the hash browns, then sprinkle with 1 cup of shredded cheddar cheese.
Mix the Egg Mixture: In a large mixing bowl, whisk together the 8 large eggs, 1 1/2 cups of whole milk or heavy cream, 1 1/2 teaspoons salt, 1 teaspoon black pepper, and 1/4 teaspoon garlic powder until the mixture is smooth and fully combined.
Assemble the Casserole: Pour the egg mixture evenly over the hash browns, sausage, and cheese layers in the baking dish. Make sure the liquid seeps through the layers to bind the casserole thoroughly.
Add Topping and Bake: Sprinkle the remaining 1 cup of shredded cheddar cheese over the top. Cover the dish tightly with aluminum foil and bake for 45 minutes.
Finish Baking: Remove the aluminum foil and continue baking for another 15-20 minutes, or until the top is golden brown, the casserole is set, and bubbly throughout. Let the casserole rest for at least 10 minutes before slicing and serving.
Notes
Use whole milk for a lighter casserole or heavy cream for a richer texture.
Drain excess grease from sausage to reduce excess fat in the casserole.
Allowing the casserole to rest helps it set and makes slicing easier.
This casserole can be made a day ahead and refrigerated, then baked just before serving to save time.
For variation, add chopped sautéed onions or bell peppers to the sausage layer.
