Use turkey sausage as a leaner alternative.
Prepare the casserole the night before and refrigerate; bake in the morning, adding a few extra minutes to the baking time.

Ingredients

Scale

Sausage Mixture

1 lb ground sausage

Egg Mixture

6 large eggs
2 cups milk
1 tsp salt
1/2 tsp black pepper

Other Ingredients

7.5 oz frozen hash brown potatoes (half of a 15 oz package)
2 cups shredded cheddar cheese

Instructions

Preheat and Prepare: Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish to prevent sticking.
Cook the Sausage: In a skillet over medium heat, cook the ground sausage until it is fully browned and no longer pink, breaking it into crumbles as it cooks. Drain excess fat if desired.
Mix the Egg Mixture: In a large bowl, whisk together the 6 eggs, 2 cups milk, 1 teaspoon salt, and 1/2 teaspoon black pepper until well combined.
Combine Ingredients: In the prepared baking dish, layer the frozen hash brown potatoes evenly across the bottom. Spread the cooked sausage evenly over the hash browns, and sprinkle the shredded cheddar cheese on top.
Pour Egg Mixture: Carefully pour the egg and milk mixture evenly over the layered ingredients in the baking dish, allowing it to soak into the hash browns and sausage.
Bake: Place the casserole in the oven and bake for 45 to 55 minutes, or until the eggs are set and the top is lightly browned. You can insert a knife or toothpick in the center—if it comes out clean, it’s done.
Rest and Serve: Remove from the oven and let the casserole sit for about 5 minutes before slicing. Serve warm and enjoy!

Notes

You can substitute cheddar cheese with other cheeses like mozzarella or pepper jack for different flavors.
Make sure to partially thaw the frozen hash browns for even cooking.
This casserole can be assembled the night before; cover and refrigerate, then bake in the morning, adding an extra 10 minutes to the baking time.
For a lower fat version, use turkey sausage and reduced-fat cheese.
Leftovers can be refrigerated for up to 3 days and reheated in the microwave.
