Imagine waking up to the irresistible aroma of a crockpot breakfast casserole that has been cooking overnight.

The rich, creamy blend of eggs, cheese, and butter melts in your mouth as savory flavors of bacon, sausage, and soft vegetables mingle with every taste.

To make this breakfast recipe, 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 of diced sweet yellow onion
  • 1 pound (2 cups) of cooked and crumbled mild breakfast sausage
  • 1 pound (1¼ cups) of cooked and crumbled smoked bacon
  • 3 cups of freshly shredded sharp cheddar cheese
  • 12 large eggs
  • ¾ cup of half and half
  • 1 tablespoon of onion powder
  • 1½ teaspoons of kosher salt
  • 1 teaspoon of cracked black pepper

Substitutions And Additions

CHEESE: You can substitute pre-packaged shredded cheese for the freshly shredded cheese in this great recipe.

The pre-packaged shredded cheese is coated in a preservative to keep the cheese from sticking together, though.

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

To make this recipe, you will layer the ingredients in your crockpot before scrambling the eggs, cream, and seasonings.

That mixture is poured over all of the other ingredients, soaking into all the nooks and crannies.

Set the slow cooker to do its thing and forget about it until morning!

Follow our step-by-step instructions below to prepare this breakfast recipe the night before.

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.

How To Serve

Consider pairing your casserole with a refreshing fruit salad, bursting with juicy, ripe flavors that provide a contrast against the savory heartiness of the main dish.

Add freshly baked, crusty bread slathered with strawberry jam, just begging to soak up every delectable morsel of creamy sauce.

Accompany this tasty breakfast with a perfectly steaming cup of coffee or even a citrusy mimosa.

This hearty breakfast casserole is also the perfect choice to make for Christmas morning.

Pop it into the slow cooker the night before, and you will have a warm and filling dish to enjoy the next day.

Pair it with our cherry breakfast braid and homemade hot chocolate.

    This looks yummy and I would love to prepare it for 2 of us. Could I half the ingredients and use a smaller crockpot? I donโ€™t mind freezing the extra but the amount as written would be way too much.
