A hands-off, crustless breakfast casserole made in the slow cooker with eggs, sausage, cheese, and hash browns. Perfect for feeding a crowd without the stress.

Ingredients

Scale
  • 12 large eggs
  • 1 cup whole milk
  • 1 pound breakfast sausage, casings removed
  • 2 cups shredded cheddar cheese
  • 4 cups frozen shredded hash browns, thawed
  • 1 small onion, diced
  • 1 medium bell pepper, diced
  • 1 teaspoon fine sea salt
  • ½ teaspoon black pepper, freshly ground
  • ½ teaspoon garlic powder
  • ½ teaspoon paprika
  • Optional: chopped green onions for garnish, hot sauce, or ½ cup sautéed mushrooms

Instructions

  1. Brown the sausage: Heat a skillet over medium-high heat. Add the sausage, breaking it apart as it cooks. Cook until browned and no longer pink, about 5-7 minutes. Transfer to a plate lined with paper towels.
  2. Sauté the veggies: In the same skillet, cook the diced onion and bell pepper over medium heat for 2-3 minutes until softened. Set aside.
  3. Whisk the eggs: In a mixing bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and paprika until smooth and slightly frothy.
  4. Grease the crockpot: Spray the inside of a 6-quart or larger slow cooker with non-stick spray or rub with butter.
  5. Layer the ingredients: Spread the thawed hash browns evenly in the bottom. Top with cooked sausage and sautéed veggies. Pour the egg mixture over everything, pressing down gently with a spatula to ensure it seeps through.
  6. Top with cheese: Sprinkle the shredded cheddar evenly over the top. Do not stir.
  7. Cook low and slow: Cover and cook on LOW for 6-7 hours or on HIGH for 3-4 hours, until the center is set and no longer jiggly.
  8. Rest before serving: Turn off the crockpot and let the casserole sit uncovered for 10 minutes to firm up.
  9. Garnish and serve: Sprinkle with chopped green onions or parsley. Serve straight from the crockpot.

Notes

Do not lift the lid during the first 4 hours of cooking. Thaw hash browns completely to avoid a watery casserole. For best texture, cook on LOW rather than HIGH.
