Description

A hearty hashbrown breakfast casserole made with sausage, eggs, cheese, and golden hash browns. Easy to prepare, customizable with veggies or different cheeses, and perfect for feeding a crowd at brunch or holidays.


Ingredients

  • 1 pound breakfast sausage, crumbled
  • 1 cup yellow onion, finely chopped
  • 1 teaspoon garlic powder
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 10 large eggs, lightly beaten
  • 1/2 cup whole milk
  • 2 cups shredded sharp cheddar cheese
  • 1 (32-ounce) package frozen shredded hash brown potatoes, thawed and drained

Instructions

  1. Preheat oven to 350°F (175°C) and grease a 9×13-inch baking dish.
  2. Cook sausage in a skillet over medium-high heat until browned. Drain excess grease. Add onions and cook until soft, about 5 minutes. Stir in garlic powder, salt, and pepper.
  3. In a large bowl, whisk eggs and milk. Stir in shredded cheddar cheese and sausage-onion mixture.
  4. Fold in thawed and drained hash browns until evenly combined.
  5. Pour mixture into prepared baking dish and spread evenly.
  6. Bake 40–50 minutes, until golden brown on top and the center is set.
  7. Let casserole rest 5 minutes before slicing and serving.

Notes

  • Swap sharp cheddar with Monterey Jack, Colby, or your favorite cheese.
  • Add cooked veggies like mushrooms, spinach, peppers, or broccoli for extra flavor.
  • Season with smoked paprika or dried herbs for depth.
  • Make it dairy-free by using plant milk and vegan cheese.
  • Reheat leftovers in the oven for best results, or freeze slices for up to 2 months.
