Making this incredible casserole is straightforward when you follow these easy steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking.
2. Cook Sausage: In a skillet over medium heat, cook the breakfast sausage until browned. Make sure to crumble it as it cooks. Drain excess fat.
3. Grease the Pan: Grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking.
4. Layer Hashbrowns: Spread the frozen hashbrowns evenly across the bottom of the baking dish.
5. Add Sausage: Evenly distribute the cooked sausage over the hashbrowns.
6. Mix Eggs and Milk: In a large mixing bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, pepper, and paprika until well combined.
7. Add Cheese: Stir in the cheddar and Monterey Jack cheeses, reserving some for topping.
8. Pour Mixture: Pour the egg and cheese mixture over the hashbrowns and sausage in the baking dish.
9. Top with Cheese: Sprinkle any reserved cheese over the top for an extra cheesy finish.
10. Cover and Refrigerate: Cover the dish with plastic wrap and refrigerate overnight.
11. Bake: The next morning, remove the cover and bake in the preheated oven for about 40-45 minutes or until the casserole is set and golden on top.
12. Cool Slightly: Allow it to cool for 5-10 minutes before slicing.

These steps will guide you in creating a comforting and scrumptious breakfast that’s perfect for making the morning special.
