This easy breakfast casserole features savory sausage, crispy frozen hash browns, and melted cheddar cheese in a rich egg custard. Perfect for holidays, weekends, and feeding a crowd with minimal effort.

Ingredients

Scale
  • 1 lb ground breakfast sausage
  • 1 (30 oz) bag frozen shredded hash browns
  • 2 cups shredded cheddar cheese
  • 8 large eggs
  • 2 cups whole milk
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon garlic powder
  • ¼ teaspoon onion powder
  • 2 tablespoons unsalted butter

Instructions

  1. Preheat your oven to 350°F (175°C). Rub the inside of a 9×13-inch baking dish with 2 tablespoons of butter. Set aside.
  2. Cook the ground breakfast sausage in a skillet over medium-high heat, breaking it up with a spatula, until browned and crumbly (6-8 minutes). Set aside to cool slightly.
  3. Spread the frozen shredded hash browns evenly across the bottom of the buttered baking dish. Do not press them down.
  4. Sprinkle the cooked sausage evenly over the hash browns.
  5. Sprinkle the shredded cheddar cheese over the sausage layer.
  6. In a large mixing bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and onion powder until uniform.
  7. Slowly pour the egg mixture over the casserole, covering as much surface area as possible. Tilt the dish gently to help it spread.
  8. Let the assembled casserole rest on the counter for 10-15 minutes.
  9. Bake for 45-55 minutes, until the edges are golden brown and the center is set (a knife inserted in the center should come out clean).
  10. Let the casserole rest for 5-10 minutes before cutting into squares and serving.

Notes

Do not thaw the hash browns; use them frozen for the best texture. Let the assembled casserole rest before baking to ensure even cooking. For make-ahead, assemble the night before and refrigerate; add 10-15 minutes to baking time. For extra crispy edges, brush exposed hash browns with melted butter before baking.
