Ingredients
  

For the Casserole
For the Egg Mixture

Equipment

  • Large skillet
  • 9x13-inch baking dish
  • Whisk
  • Mixing Bowl

Method
 

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish with cooking spray or oil.
  2. In a large skillet, cook the breakfast sausage over medium heat until browned, breaking it apart with a spoon. Drain off excess grease.
  3. Add the diced onion and bell pepper to the skillet with the sausage. Cook until the vegetables are softened, about 5-7 minutes. Stir in 1/2 teaspoon of kosher salt.
  4. Spread the frozen shredded potatoes evenly in the prepared baking dish. Top with the sausage and vegetable mixture.
  5. In a large mixing bowl, whisk together the eggs, sour cream, milk, Dijon mustard, and 1/4 teaspoon kosher salt until well combined.
  6. Pour the egg mixture evenly over the potatoes and sausage in the baking dish.
  7. Sprinkle the shredded cheddar cheese and black pepper over the top.
  8. Bake for 45-55 minutes, or until the casserole is set and golden brown. A knife inserted into the center should come out clean.
  9. Let the casserole rest for 10 minutes before slicing and serving.

Notes

This casserole is naturally gluten-free if you use gluten-free sausage. It can be assembled the night before and refrigerated. If baking from cold, add an additional 5-10 minutes to the baking time.
