  • 1/2 teaspoon black pepper
  • 3 cups mild cheddar cheese shredded, divided
  • 30 ounces frozen hash browns thawed and drained (see note)

  • Add the red pepper, onion, and garlic to the skillet and cook until they are soft, about 5 to 7 minutes. When they are done cooking, drain any excess grease from the pan.

  • In a large bowl, combine the eggs, milk, salt, and pepper. Then add in the sausage mixture and 1 1/2 cups of the cheese. Finally, stir in the thawed and drained hashbrowns until the mixture is well combined.
    8 eggs, 1 cup milk, 1 1/2 teaspoon kosher salt, 1/2 teaspoon black pepper, 3 cups mild cheddar cheese, 30 ounces frozen hash browns
  • Pour the mixture into the prepared casserole dish. Top with the remaining 1 1/2 cups of cheese. Cover and bake for 50 minutes. Uncover and bake for a remaining 5 to 10 minutes. Let the casserole sit for 10 minutes before cutting and serving warm.

Notes

This recipe works best if you squeeze the excess liquid out of the thawed hash browns before making this.
