Ingredients

Scale
  • 1 pound breakfast sausage, casings removed if using links
  • 1 (30 oz) bag frozen shredded hash browns, thawed (about 6 cups)
  • 1 medium yellow onion, diced
  • 1 red bell pepper, diced
  • 2 cups shredded sharp cheddar cheese, divided
  • 8 large eggs
  • 1 1/2 cups whole milk
  • 1/2 cup heavy cream or half and half
  • 1 teaspoon garlic powder
  • 1 teaspoon dried mustard powder
  • 1/2 teaspoon smoked paprika
  • 1/2 teaspoon salt (adjust based on sausage saltiness)
  • 1/4 teaspoon black pepper
  • Cooking spray or butter for greasing

Instructions

  1. Preheat oven to 375°F (190°C). Generously grease a 9×13 inch baking dish.
  2. In a large skillet over medium heat, cook sausage, breaking it up, until browned. Add onion and bell pepper in the last 3-4 minutes to soften. Drain excess grease and let cool slightly.
  3. Spread thawed hash browns evenly in the prepared dish. Top with sausage mixture and 1 1/2 cups cheese.
  4. In a large bowl, whisk eggs, milk, cream, garlic powder, mustard powder, smoked paprika, salt, and pepper until smooth.
  5. Pour egg mixture evenly over the layers in the dish. Gently poke with a fork to help custard seep down. Top with remaining 1/2 cup cheese.
  6. Bake, uncovered, for 55 to 65 minutes, until edges are golden, center is set (no jiggle), and a knife inserted near center comes out clean.
  7. Let casserole rest for 10-15 minutes before slicing and serving.

Notes

For best results, ensure hash browns are fully thawed. Letting the casserole rest after baking is crucial for clean slices. Can be assembled the night before, covered, and refrigerated; bake as directed, adding a few minutes if needed. For a lighter version, use turkey sausage and reduced-fat dairy.
