Ingredients

  • 1 pound frozen shredded hash brown potatoes
  • 1/2 pound breakfast sausage
  • 1/2 pound bacon cooked and crumbled
  • 2 cups shredded cheddar cheese divided
  • 1/2 medium sweet onion diced
  • 1/2 green pepper diced
  • 1/2 red pepper diced
  • 12 eggs
  • 1 cup milk
  • 1/2 cup sour cream
  • 1/2 teaspoon salt
  • 1/4 teaspoon ground black pepper

Instructions

  • In a large skillet over medium heat, brown sausage with diced onion and peppers until fully cooked and no longer pink. Drain excess grease and set aside.
  • Grease a 6-quart (or larger) slow cooker with cooking spray or butter.
  • Layer half of the hash browns in the bottom of the slow cooker.
  • Top with half of the sausage mixture, half of the bacon, and half of the cheese.
  • Repeat layers with remaining hash browns, sausage mixture, and bacon (reserving some cheese for topping).
  • In a large mixing bowl, whisk together eggs, milk, sour cream, salt, and pepper until smooth.
  • Pour egg mixture evenly over the layered ingredients.
  • Cover and cook on low for 6–8 hours or on high for 2–3 hours.
  • Sprinkle remaining cheese over the top and cover until melted.
  • Serve warm with your favorite fresh toppings.

Notes

  • Grease the Slow Cooker Well: Prevents sticking.
  • Don’t Overcook: Check for doneness around the minimum cook time.
  • Use Freshly Shredded Cheese: Melts better than pre-shredded.
  • Add Veggies: Spinach or mushrooms work great.
  • Let It Rest: Allow a few minutes before slicing for cleaner servings.
