Equipment

  • Slow Cooker
  • Non-stick Cooking Spray
  • Large Mixing Bowl
  • Whisk

Ingredients

  • 30 ounces Frozen Shredded Hash browns 1 package
  • 1 pound ground sausage browned and drained
  • 2 cups shredded cheddar cheese
  • ½ cup shredded Mozzarella cheese
  • 1 onion diced
  • 1 green pepper diced
  • 1 red pepper diced
  • 12 eggs
  • ½ cup milk
  • ½ teaspoon salt
  • ¼ teaspoon black ground pepper

Instructions

  • Spray a 6 quart slow cooker with nonstick cooking spray (you cannot make this recipe in a smaller crock pot because it won't fit). Layer 1/2 of the potatoes on the bottom of slow cooker.
  • Top with half of the sausage, cheddar and mozzarella cheese, onions, green peppers, and red peppers. Repeat the layers again.
  • Beat eggs, milk, and salt and pepper in large bowl with a wire whisk until well blended. Pour egg mixture evenly over potato-sausage mixture.
  • Cook on low setting for 8 hours or on high setting for 4 hours or until eggs are set.
  • Top with green onions, salsa, tomatoes, mushrooms, avocado- whatever you like!

Notes

  • Like an oven, every slow cooker cooks differently. We have tested this recipe for both 8 hours on low and 4 hours on high, and have had success both ways (without it overcooking). If you’re nervous about it being overdone, we would recommend checking it halfway through your cook time and adjusting as necessary.
  • This recipe fits perfectly in a 6-quart slow cooker. If you want to halve this recipe, we would recommend using a 4-quart slow cooker to help prevent it from burning.
  • Cook and drain the sausage before putting it in the slow cooker to prevent extra grease build-up.
  • To bump up the flavor, try using Italian sausage, diced green chiles, or your favorite seasonings.
  • You can substitute other vegetables for the peppers and onions (we like to add in mushrooms) or omit them if don’t care for them.
  • Substitute other meats for the sausage. We like using leftover ham or bacon (cooked and drained of grease as much as possible).
