Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with cooking spray or butter.
In a large skillet, melt the butter over medium heat. Add the frozen hash browns and cook until golden and lightly crispy, about 8-10 minutes. Spread the cooked hash browns evenly in the prepared baking dish.
In the same skillet, cook the breakfast sausage over medium-high heat, breaking it apart with a spoon, until browned and fully cooked (about 7-8 minutes). Drain excess grease if necessary and transfer the sausage to the baking dish, spreading it evenly over the hash browns.
Using the same skillet, sauté the diced onion until softened and translucent, about 3-4 minutes. Layer the cooked onions over the sausage in the casserole dish.
In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and paprika until fully combined.
Stir in 1.5 cups of the shredded cheddar cheese and the grated Parmesan cheese into the egg mixture.
Pour the egg and cheese mixture over the hash browns, sausage, and onions in the casserole dish, making sure it spreads evenly.
Sprinkle the remaining 0.5 cup of shredded cheddar cheese on top of the casserole.
Bake in the preheated oven for 40-45 minutes, or until the center is set and the top is golden and bubbly.
Remove the casserole from the oven and let it rest for 5-10 minutes before slicing and serving.
Garnish with chopped green onions, if desired. Serve warm and enjoy!
