Ingredients

  • 1 pound ground breakfast sausage turkey or sub ground beef
  • 14 oz bag frozen peppers and onions do not thaw, use frozen
  • 1 tablespoon avocado oil
  • 1 4 oz can green chilis
  • 3 cups hash browns frozen
  • 1 cup cheddar cheese shredded (can sub dairy-free)
  • 1 cup mozzarella cheese shredded (can sub dairy-free)
  • 6 large eggs
  • 3/4 cup or 4 large egg whites
  • 1 teaspoon salt more or less to taste
  • 1/2 teaspoon pepper
  • 2 tsp taco seasoning
  • 2 tbsp hot sauce I used Franks, OPTIONAL
  • 1/2 teaspoon garlic powder
  • 1/4 cup milk of choice skim, whole, or coconut
  • 3/4 cup cottage cheese or sub-Greek or dairy-free yogurt plain
  • green onion or fresh chives for garnish

Instructions

  • Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking dish with cooking spray or butter.
  • Heat the olive or avocado oil in a large skillet over medium heat. Add the sausage, breaking it apart with a spoon or spatula and cook until browned. Remove any excess grease.
  • In a large mixing bowl, whisk together the eggs, cottage cheese, milk hot sauce, and seasoning. Mix until well combined.
  • Add the frozen hash brown potatoes, frozen peppers/onions, green chilis, 1/2 cup shredded cheddar cheese, ½ cup shredded mozzarella cheese and the cooked sausage to the casserole dish. Mix everything together until evenly combined and spread out evenly in the pan.
  • Pour the egg mixture over the hashbrowns, veggies and sausage and cover with the remaining cheese.
  • Bake in the preheated oven for 45-55 minutes, or until the casserole is set in the middle and the top is golden brown.
  • Once done, remove the casserole from the oven and let it cool for a few minutes before slicing.
  • Garnish with Greek yogurt, chopped fresh chives or green onions

Notes

Expert Tips & Variations

  • To make this hash brown breakfast casserole dairy-free, use dairy-free yogurt and vegan cheese shreds (or omit the cheese). 
  • Feel free to add cooked and chopped ham or bacon for additional meat in this recipe, or substitute it entirely. 

Storage Tips

Store leftovers in an airtight container in the fridge for up to 3-4 days. Reheat gently in the microwave and serve with desired toppings. 
To freeze, I recommend letting the casserole cool completely. Then, wrap individual servings in plastic wrap and store them in an airtight, freezer-safe container or freezer bag for up to 2-3 months.
