Ingredients

  • 1 lb. breakfast sausage
  • 1 cup diced bell pepper green, red or a combination
  • 1 small onion diced
  • 12 large eggs
  • 1 cup sour cream
  • ¼ cup half and half or milk
  • 3 cups frozen shredded hash brown potatoes thawed
  • 2 cups shredded sharp cheddar cheese
  • ½ teaspoon salt
  • ½ teaspoon pepper

Instructions

  • Preheat your oven to 350°F (177°C) and lightly grease a 9 x 13" casserole dish.
  • Place the thawed hash brown potatoes into a colander and gently squeeze to remove excess moisture. Let them sit in the colander while you prepare the remaining ingredients. (Frozen hash brown potatoes can be thawed in the microwave if you are short on time.) See notes for using fresh potatoes.
  • In non-stick skillet, cook the breakfast sausage, peppers and onions over medium to medium-high heat for 7-10 minutes. The meat should be browned and fully cooked and vegetables softened. Remove the skillet from the heat and set aside to cool down.
  • In a large mixing bowl, whisk together the eggs, sour cream and half and half. Add the shredded cheese, hash brown potatoes, sausage mixture, salt, pepper and stir to combine.
  • Pour the mixture into the casserole dish and bake for 50-60 minutes or until the edges are set, lightly browned and the center is slightly jiggly. The center should register at least 160 °F (71.1 °C) using a digital food thermometer.
  • Remove the casserole from the oven and let it rest for 15 minutes in order to firm up before slicing.

Notes

  • If using freshly grated potatoes, place them in a colander and squeeze out excess moisture before adding them to the egg mixture. This step will help prevent a "runny" casserole.
  • To Store: Keep leftovers in the fridge, covered for up to 4 days.
  • To Freeze: Cut the baked casserole into squares. Wrap each one in plastic and stick them in a freezer-safe bag. Keep frozen up to 3 months in the freezer.
  • To Reheat: Allow the casserole to thaw in the fridge. Reheat in the microwave at 50% power in 1 minute intervals or in the oven at 350°F until heated through.
