Ingredients for Egg & Hashbrown Breakfast Casserole

The Egg Base

6 large eggs
1 cup milk

The egg and milk mixture creates a fluffy, custard-style base that binds the hashbrowns and sausage together in this classic breakfast casserole.

The Hearty Layer

1 (30 oz) bag frozen shredded hashbrowns, thawed

Thawed hashbrowns form the foundation of this casserole, giving it a crispy-yet-tender texture that makes every bite satisfying.

1 pound breakfast sausage or bacon, cooked and crumbled

Sausage adds rich, savory flavor, while bacon provides smoky depth. Either works beautifully in this breakfast bake.

The Vegetables

1 onion, diced
1 bell pepper, diced

Onion and bell pepper add freshness, flavor, and color, balancing the richness of the cheese and sausage.

The Seasoning

1 teaspoon garlic powder
1 teaspoon salt
½ teaspoon black pepper

Simple seasoning enhances the savory breakfast flavors without overpowering the dish.

The Cheesy Topping

2 cups shredded cheddar cheese

Cheddar melts into the casserole and creates a golden, bubbly topping. Reserve some cheese for sprinkling on top before baking.

2 tablespoons chopped parsley (for garnish)

Parsley adds a fresh finishing touch and brightens the presentation.

How to Make Egg & Hashbrown Breakfast Casserole

Begin by preheating your oven and greasing a 9×13 baking dish. Cook and crumble your breakfast sausage or bacon, then set aside.

Spread thawed shredded hashbrowns evenly across the bottom of the dish to create the base layer. Add the cooked meat, diced onion, and bell pepper for flavor and texture. Sprinkle most of the shredded cheddar cheese over the top.

In a separate bowl, whisk together eggs, milk, and seasonings until smooth. Pour the mixture evenly over the casserole layers. Top with remaining cheese and bake covered, then uncovered, until the casserole is fully set and golden brown on top.
