Hash brown and sausage casserole bakes crispy hash browns with savory sausage, eggs, and cheese for a hearty family brunch. This protein-packed breakfast dish is perfect for make-ahead holiday mornings.
Preheat your oven to 375°F (190°C) and generously grease a 9x13-inch baking dish.
In a large skillet over medium heat, cook the breakfast sausage, breaking it into crumbles, until well-browned and no longer pink. Drain excess fat.
Evenly spread the frozen hash browns in the prepared baking dish and top with the cooked sausage, ensuring both are distributed in an even layer.
In a large bowl, whisk together the eggs, whole milk, salt, black pepper, and paprika until fully combined. Stir in half of the shredded cheddar cheese.
Pour the egg mixture evenly over the hash browns and sausage, then top with the remaining cheddar cheese. Bake uncovered for 40–45 minutes until the center is set and the top is golden brown. Let it rest for 10 minutes before slicing and serving.
