• 2 cups shredded cheddar cheese

• ½ cup shredded mozzarella cheese

• Butter or spray oil (for greasing the pan)

Instructions:

1. Preheat and prep: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray.

2. Cook the sausage: In a skillet over medium heat, cook the sausage until browned and fully cooked. Break it into crumbles as it cooks. Drain any excess grease and set aside.

3. Mix the eggs: In a large mixing bowl, whisk together the eggs, milk, salt, pepper, and garlic powder until fully combined.

4. Assemble the casserole: Layer the thawed hash browns evenly on the bottom of the prepared baking dish. Sprinkle the cooked sausage and diced onion (if using) evenly over the potatoes. Pour the egg mixture over everything. Top with shredded cheddar and mozzarella cheese.

5. Bake: Place the casserole in the preheated oven and bake for 45–50 minutes, or until the top is golden and the center is set (a knife inserted should come out clean).

6. Cool and serve: Let the casserole cool for about 10 minutes before slicing. Serve warm.

Make-Ahead Tip:

You can assemble the casserole the night before. Cover and refrigerate overnight, then bake fresh in the morning—just add an extra 5–10 minutes to the baking time.

Storage:

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual slices in the microwave or oven.
