2 lb frozen diced hash browns

1 lb breakfast sausage, browned

15 oz country sausage gravy

2 cups shredded cheddar cheese, divided

6 large eggs, whisked

2 cups crushed corn flakes

4 tbsp melted butter

Salt, to taste

Black pepper, to taste

Garlic powder, to taste

Cooking spray

Directions

I preheat the oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish with cooking spray.

In the prepared dish, I combine the frozen hash browns, browned breakfast sausage, country sausage gravy, 1 cup of shredded cheddar cheese, salt, black pepper, and garlic powder. I stir everything together until well mixed.

Next I pour the whisked eggs evenly over the potato mixture.

I sprinkle the remaining 1 cup of cheddar cheese over the top.

In a small bowl, I mix the crushed corn flakes with the melted butter until evenly coated.

I spread the buttered cornflake mixture over the casserole.

Then I bake for 60 to 70 minutes, or until the potatoes are tender and the eggs are fully set.

I let the casserole rest for about 5 minutes before slicing and serving.

Variations

I like to customize this casserole depending on the occasion. Sometimes I substitute the breakfast sausage with diced turkey sausage for a different flavor. When I want extra vegetables, I add sautéed bell peppers, onions, mushrooms, or spinach. For a spicier version, I mix in diced jalapeños or a pinch of cayenne pepper. I also enjoy experimenting with different cheeses such as Monterey Jack, pepper jack, mozzarella, or Colby Jack to create new flavor combinations.

Storage/Reheating

I store leftover casserole in an airtight container in the refrigerator for up to 4 days. For longer storage, I wrap individual portions tightly and freeze them for up to 2 months. When reheating, I warm slices in the microwave for 1 to 2 minutes or until heated through. If I want to maintain the crispy topping, I reheat portions in a 350°F oven for about 15 to 20 minutes.
