Step-by-Step Instructions

1. Cook the Sausage and Vegetables

In a large skillet over medium heat, brown the breakfast sausage, breaking it up into crumbles. Once it starts to brown, add in the diced onion and bell pepper, and cook until the vegetables are soft and the sausage is fully cooked. Drain excess fat if needed.

2. Assemble the Base

In a greased 9×13-inch baking dish, spread the frozen hash browns evenly across the bottom. Layer the cooked sausage and vegetables on top, followed by 1 cup of the shredded cheddar cheese.

3. Mix the Egg Custard

In a large mixing bowl, whisk together the eggs, milk, salt, pepper, and garlic powder until fully combined. This mixture will soak into the hash browns and set into a creamy, savory custard when baked.

4. Pour and Top

Carefully pour the egg mixture over the layers in the baking dish, ensuring even distribution. Top with the remaining ½ cup of cheddar cheese.

5. Bake

Preheat your oven to 375°F (190°C). Bake the casserole uncovered for 40-45 minutes, or until the eggs are set in the center and the top is golden brown.

6. Cool and Garnish

Let the casserole rest for 10 minutes before slicing. Garnish with chopped green onions or parsley for a fresh finishing touch.
