Equipment

Ingredients
  

  • 12 ounces breakfast sausage casings removed
  • ¾ bag hash browns about 20 ounces, frozen diced, thawed
  • ½ cup onion diced
  • ½ cup red bell pepper diced
  • 2 teaspoons kosher salt divided
  • 1 teaspoon black pepper divided
  • 6 ounces sharp Cheddar cheese shredded (about 1½ cups), divided
  • 3 large eggs lightly beaten
  • 1/2 cup whole milk
  • 1 tablespoon flat-leaf parsley

Instructions
 

  • Preheat the oven to 350°F. Grease a 9x13-inch baking dish with butter or cooking spray.
  • In a large nonstick skillet, cook the sausage over medium-high heat until browned and fully cooked, about 10 minutes. Drain the sausage on paper towels.
  • Add the oil to the same skillet and cook the hash browns for 6-8 minutes or until lightly browned. Add the onion and bell pepper and cook for an additional 3-4 minutes or until the onion starts to soften. Season with 1 teaspoon salt and ½ teaspoon black pepper.
  • In a large mixing bowl, combine the cooked sausage, hash browns, and 1 cup of the shredded cheddar cheese. Transfer the mixture to the prepared baking dish.
  • In a medium bowl, whisk the eggs, milk, remaining 1 teaspoon salt, and ½ teaspoon black pepper. Pour the egg mixture over the sausage mixture in the baking dish.
  • Sprinkle the remaining ½ cup of shredded cheddar cheese over the top.
  • Bake the casserole uncovered for 30 minutes, or until the center is set and the top is golden brown.
  • Let cool for 5 minutes. Garnish with chopped parsley and serve warm.
