Ingredients

Scale
  • 1 (30 oz) package frozen shredded hash browns, thawed
  • 1 lb breakfast sausage, cooked and crumbled
  • 1 medium yellow onion, diced
  • 1 red bell pepper, diced
  • 2 cups shredded sharp cheddar cheese, divided
  • 8 large eggs
  • 1 cup whole milk
  • 1 cup sour cream
  • 1 teaspoon garlic powder
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon salt
  • Cooking spray or butter for greasing

Instructions

  1. Preheat oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
  2. Place thawed hash browns in a clean kitchen towel. Wring tightly over the sink to remove all excess moisture.
  3. In a large bowl, combine the squeezed hash browns, cooked sausage, diced onion and bell pepper, and 1 1/2 cups of the cheddar cheese. Mix well and press evenly into the prepared dish.
  4. In the same bowl, whisk together eggs, milk, sour cream, garlic powder, smoked paprika, black pepper, and salt until smooth.
  5. Pour the egg custard mixture evenly over the hash brown base. Top with the remaining 1/2 cup of cheese.
  6. Bake for 55-60 minutes, until the center is set and the top is golden brown.
  7. Let the casserole rest for 10 minutes before slicing and serving.

Notes

For a make-ahead option, assemble the casserole, cover, and refrigerate overnight. Bake as directed, adding a few extra minutes if needed. Ensure hash browns are thoroughly squeezed to prevent sogginess. Letting the casserole rest before slicing is crucial for clean portions.
