Instructions

  • Prep. Spray the inside of crockpot with nonstick cooking spray.
  • Cook. In a large skillet, brown and crumble the sausage (2 (9-ounce) packs). Remove to a paper towel-lined plate and set aside. Remove all the grease. Cook bacon (1 pound) in the same defatted skillet until brown and crispy. Drain on a paper towel-lined plate. Crumble.
  • Combine. To a mixing bowl add eggs (12), milk (1 cup), Italian seasoning (1 1/2 teaspoons), dry mustard (1 teaspoon), garlic powder (1/2 teaspoon), salt (1/2 teaspoon), and pepper (1/4 teaspoon), and whisk to combine. Stir in 1 1/2 cups cheddar; set aside.
  • Layer Remaining Ingredients. Spread the hash browns (1 (1 pound) bag) in an even layer on the bottom of the crock. Layer the sausage and bacon in the crock, over hashbrowns. Sprinkle green onions (2-3 tablespoons) evenly on top. Pour egg mixture layers.
  • Cook. Cover and cook on low, for 4 ½ to 6 ½ hours, or on high for 2 ½ to 3, or until the eggs are fluffy and set. Sprinkle top with remaining 1/2 cup cheddar and mozzarella (1 cup). Cover and cook just until cheese is melted.
  • Enjoy! Garnish with additional green onions, spoon out individual portions and serve!

Notes

  1. Hash browns come in all shapes and sizes. I prefer the shredded ones, but you can experiment with different kinds. You can even try the ones with frozen peppers for an extra kick! The only adjustment you might need to make is cooking slightly longer if the potato is really chunky! You can also use refrigerated hashbrowns.
  2. Breakfast Sausage Links: You can use breakfast sausage packaged in a roll (like Jimmy Dean), instead of links, and skip the step of removing the casing!
  3. Milk: I like to use whole milk in this recipe but you can use a lower fat option.
  4. Cheddar Cheese: Cheddar is delicious in this casserole. Colby Jack is a good substitute!
  5. Mozzarella: You can buy the pre-grated kind, but it's coated with cellulose (wood pulp!) I like to grate it myself. The easiest way to grate mozzarella is to let it sit in the freezer for about 15 minutes before you grate it, so it firms up enough that it doesn’t crumble in your grater!
  6. Liner: You can use a slow cooker liner for an easy cleanup.
  7. Nonstick Cooking Spray: I spray the crockpot before adding the ingredients to help prevent it from sticking.
  8. What Size Crock Pot Should I Use? I use my 6-quart crockpot. If you don't have a crockpot this large, you can cut the recipe in half, reduce the cooking time a bit, and use a smaller unit.
  9. Crockpot Temperatures: Remember crockpot temperatures vary. Your exact cooking time will depend on how your crockpot temperature runs.
  10. Switch up the meat in the casserole: Instead of sausage and bacon, try ham, chicken sausage, or turkey bacon. 
  11. Optional Toppings: Top this with extra green onions and/or bacon. Fresh salsa, hot sauce, avocado, and a dollop of sour cream are also nice to add freshness.
  12. Crockpot Breakfast Casserole Without Hash Browns: Substitute the hashbrowns with well-drained frozen chopped cauliflower or broccoli.
  13. Crockpot Breakfast Casserole With Bread: Substitute the hashbrowns with 2 cups of cubed day-old bread.
  14. Add Veggies: This is great with fresh spinach and or mushrooms added.
