Step-by-Step Instructions

1. Preheat the Oven: Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish with butter or cooking spray.
2. Cook the Sausage: Heat a skillet over medium heat and cook the breakfast sausage until browned and fully cooked. Drain any excess grease and set aside.
3. Prepare the Egg Mixture: In a large mixing bowl, whisk together the eggs, milk, garlic powder, onion powder, paprika, salt, and black pepper until well combined.
4. Assemble the Casserole: Spread the hash browns evenly into the prepared baking dish. Top with the cooked sausage, diced onion, bell pepper, and half of the shredded cheeses.
5. Add the Eggs: Slowly pour the egg mixture over the casserole, making sure it covers all the ingredients evenly. Sprinkle the remaining cheese over the top.
6. Bake: Place the casserole in the oven and bake for 35–40 minutes, or until the eggs are fully set and the top is golden brown.
7. Rest and Serve: Let the casserole rest for 5–10 minutes before slicing. Garnish with fresh parsley and serve warm.
