Ingredients
Breakfast sausage 1 lb
Frozen shredded hash browns 4 cups
Large eggs 8
Whole milk 1 1/2 cups
Shredded cheddar cheese 2 cups
Shredded mozzarella or Monterey Jack cheese 1 cup
Salt 1/2 teaspoon
Black pepper 1/4 teaspoon
Garlic powder 1/2 teaspoon
Onion powder 1/2 teaspoon
Butter or cooking spray for greasing the dish
Instructions
Step 1: Preheat and prepare the dish
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish generously with butter or cooking spray to prevent sticking.
Step 2: Cook the sausage
Place a large skillet over medium heat. Add the breakfast sausage and cook, breaking it into small crumbles, until fully browned and cooked through. Drain off excess grease and set the sausage aside.
Step 3: Build the base
Spread the frozen shredded hash browns evenly across the bottom of the prepared baking dish. Sprinkle the cooked sausage evenly over the hash browns.
Step 4: Add the cheese
Sprinkle the shredded cheddar and mozzarella (or Monterey Jack) evenly over the sausage layer, making sure the cheese is well distributed for even melting.
Step 5: Mix the egg mixture
In a large bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and onion powder until smooth and well combined.
Step 6: Assemble the casserole
Slowly pour the egg mixture evenly over the layers in the baking dish. Gently tap the dish on the counter to help the liquid settle throughout the casserole.
Step 7: Bake
Place the casserole uncovered in the preheated oven. Bake for 45–55 minutes, or until the center is set, the top is lightly golden, and a knife inserted in the middle comes out clean.
Step 8: Rest and serve
Remove the casserole from the oven and let it rest for 5–10 minutes before slicing. This helps it firm up and makes serving easier.
