Equipment

Ingredients
  

  • 8-10 frozen hashbrown patties
  • 1 lb breakfast sausage cooked and drained
  • 8 large eggs
  • 1 ½ cups milk
  • 1/4 cup sour cream
  • 2 cups shredded cheese cheddar or Colby Jack
  • 1 tsp salt
  • ½ tsp black pepper
  • ½ tsp garlic powder optional
  • ½ tsp paprika optional

Method
 

  1. Grease a 9×13 baking dish. Arrange hashbrown patties in a single layer. (I cut a hashbrown in half to fit them all the way across)
  2. Sprinkle cooked sausage on top.
  3. Whisk together eggs, milk, sour cream, and seasonings. Pour evenly over the casserole.
  4. Sprinkle over the shredded cheese.
  5. Cover and refrigerate overnight.
  6. In the morning, preheat oven to 350°F. Bake, uncovered, 45–55 minutes or until center is set.
  7. Rest 10 minutes before slicing. Enjoy!
  8. This casserole can also be baked after assembling. Pop it into a 350°F oven, uncovered, for 45-50 minutes until the eggs are set and the top is golden brown.
  9. Serve this breakfast casserole with fresh fruit, a simple green salad, or a side of biscuits. It’s also great with hot sauce, salsa, or a drizzle of maple syrup for that sweet-and-savory vibe.
