Ingredients

  • 1 lb breakfast sausage see below for directions on how to make your own!
  • ¼ cup chopped green onions plus more for garnish
  • 1 16 oz package hash browns, thawed or 3 potatoes peeled and grated
  • 12 eggs
  • ¼ cup almond or coconut milk
  • 1 tsp sea salt
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tbsp everything bagel seasoning
  • ½ cup Kite Hill Chive Cream Cheese optional

Sausage (If making your own)

  • 1 lb ground pork
  • 1 tsp fennel seeds
  • 1 tsp salt
  • 2 tsp ground sage
  • 1 tsp thyme
  • ½ tsp black pepper
  • ¼ tsp cayenne pepper
  • ½ tsp garlic powder
  • ¼ tsp all spice

Instructions

  • If making your own sausage, combine all ingredients in a large saute pan. If using store bought sausage, add it to the pan. Use a spoon to break the pork apart and cook/stir for 5-7 minutes until browned and cooked through. 
  • Preheat oven to 350. Spray a 9x13 casserole dish with olive or avocado oil. Spread the hash browns out evenly on the bottom of the pan until covered. Sprinkle the diced green onions over the hash browns, then add the sausage evenly spread out on top. Place small spoonfuls of cream cheese on top of the sausage (if using).
  • In a large bowl, whisk the eggs, almond or coconut milk, and remaining spices together. Pour the egg mixture evenly over the hash browns, sausage, and green onions. Use a spatula to gently mix it together/spread the cream cheese around. Bake for 50 minutes or until the eggs are set. Slice, serve with hot sauce, ranch, or ketchup and more green onions. Enjoy!

Notes

  • Fridge: Keep leftovers in an airtight container for up to 5 days. Reheat in the microwave for 2-3 minutes.
  • Freezer: Slice, cool, and store in freezer-safe containers for up to 2 months. Thaw overnight in the fridge and reheat at 325°F for 25 minutes. A true freezer-friendly casserole.
  • Make Ahead: This is the perfect make ahead breakfast casserole. All you have to do is assemble the casserole the night before, cover, and refrigerate. Bake fresh in the morning for a stress-free breakfast casserole. It’s great for a Christmas morning breakfast, Easter brunch, or even Mother’s Day breakfast.
