Crockpot Breakfast Casserole Ingredients

Crockpot Breakfast Casserole raw ingredients that are labeled

You’ll need:

  • 1 (28-ounce) package of frozen O’Brien hash browns
  • 1 medium (1 cup) diced green pepper
  • 1 medium (1 cup) diced red bell pepper
  • ½ cup diced sweet yellow onion
  • 1 pound (2 cups) cooked and crumbled mild breakfast sausage
  • 1 pound (1¼ cups) cooked and crumbled smoked bacon
  • 3 cups freshly shredded sharp cheddar cheese
  • 12 large eggs
  • ¾ cup half and half
  • 1 tablespoon onion powder
  • 1½ teaspoons kosher salt
  • 1 teaspoon cracked black pepper

SUBSTITUTIONS AND ADDITIONS

CHEESE: You can substitute pre-packaged shredded cheese for the freshly shredded cheese in this great recipe, but the pre-packaged shredded cheese is coated in a preservative to keep the cheese from sticking together. This means it does not have the same creaminess as freshly shredded cheese.

SPICY: If you want a spicier egg casserole, you can use hot sausage instead of mild. You can also add tabasco sauce, a dash of red pepper flakes, or diced green chiles to the egg mixture in your breakfast crockpot casserole.

GROUND MEAT: If you are looking for a different option for the breakfast sausage, you could use regular ground sausage, turkey sausage, or Italian sausage in this easy breakfast casserole.

How to Make This Crockpot Breakfast Casserole Recipe

OUR RECIPE DEVELOPER SAYS

This breakfast casserole can be cooked overnight in your slow cooker so that it is ready when you wake up the next morning.

STEP ONE: Generously spray a 6 to 7-quart crockpot with nonstick cooking spray. 

STEP TWO: Spread the frozen hash brown potatoes in the bottom of the prepared crockpot.

PRO TIP:

It’s best to keep the potatoes frozen and add them right to your crockpot without thawing. Otherwise, they may cook faster than the rest of your ingredients and will end up mushy.

STEP THREE: Sprinkle the diced green and red peppers and the diced onion over the hash browns.
