Ingredients 

For the Casserole

  • 1 pound breakfast sausage crumbled
  • 20 oz frozen hash browns thawed and patted dry
  • 8 large eggs
  • 1 cup milk whole milk recommended
  • 1.5 cups shredded cheddar cheese freshly shredded for best results
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper freshly ground
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder

Optional Add-ins & Variations

  • 1/2 cup bell peppers diced, for extra color and flavor
  • 1/2 cup spinach chopped, for a veggie boost
  • 1/2 teaspoon smoked paprika for a deeper smoky flavor
  • 1/4 teaspoon crushed red pepper flakes for a little heat

Instructions

  • Preheat your oven to 375°F (190°C) and thoroughly grease a 9x13-inch baking dish with butter or cooking spray to prevent sticking.
  • Cook the breakfast sausage in a large skillet over medium heat, using a spatula to break it into crumbles as it browns. Once fully cooked, drain all excess grease.
  • Spread the thawed and dried hash browns into an even layer across the bottom of your prepared baking dish.
  • Sprinkle the cooked sausage crumbles evenly over the layer of hash browns. In a separate mixing bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and onion powder until well combined.
  • Pour the prepared egg mixture evenly over the sausage and hash browns, then top the entire casserole with the shredded cheddar cheese.
  • Bake in the preheated oven for 35-40 minutes, or until the eggs are completely set and the cheese on top is melted, golden, and bubbly.
  • Remove the casserole from the oven and let it rest for at least 5 minutes. This helps it set for easier slicing. Serve warm and enjoy.

Equipment

  • 9x13-inch Baking Dish
  • Large Skillet
  • Mixing bowl
  • Whisk
  • Spatula

Notes

For the best texture, ensure your hash browns are fully thawed and patted dry to remove excess moisture, which prevents a soggy casserole. Using freshly shredded cheese provides a superior melt compared to pre-shredded varieties. For easy meal prep, assemble the casserole the night before, cover, and refrigerate; you may need to add 5-10 minutes to the baking time.
