03 - 1 red bell pepper, diced
04 - 1 green bell pepper, diced

# Directions:

01 - In a large skillet over medium heat, cook the sausage, breaking it up with a spoon, until browned and cooked through, approximately 7-9 minutes. Remove sausage with a slotted spoon and set aside.
02 - In the same skillet, sauté the onion and bell peppers until softened, approximately 4-5 minutes. Remove from heat.
03 - Grease a 9x13 inch baking dish. Spread the thawed hash browns evenly in the bottom.
04 - Top hash browns with cooked sausage, then the sautéed vegetables. Sprinkle cheddar and mozzarella cheeses evenly over the top.
05 - In a large bowl, whisk together eggs, milk, salt, black pepper, garlic powder, and smoked paprika until well combined.
06 - Pour the egg mixture evenly over the casserole. Cover tightly with foil or plastic wrap and refrigerate overnight for at least 8 hours.
07 - In the morning, preheat the oven to 350°F. Remove casserole from refrigerator and let stand at room temperature for 15 minutes.
08 - Bake, uncovered, for 50-60 minutes, or until eggs are set in the center and the top is lightly golden brown.
09 - Cool for 10 minutes before slicing. Garnish with fresh parsley or chives if desired.
