Ingredients

  • 1 lb bulk pork breakfast sausage, browned, drained
  • 10 large eggs
  • 1/2 cup whole milk
  • 2 cups sharp cheddar cheese, shredded
  • 1 red bell pepper, diced
  • 1 yellow onion, diced
  • 4 cups frozen shredded hash browns (thawed)
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1/2 tsp kosher salt
  • 1/4 tsp black pepper
  • as needed nonstick cooking spray

Instructions

  1. 1

    In a skillet over medium-high heat, cook 1 lb bulk pork breakfast sausage until browned and cooked through, breaking it into crumbles. Drain the fat and set aside.

  2. 2

    Coat the slow cooker insert generously with nonstick cooking spray.

  3. 3

    Spread 4 cups frozen shredded hash browns (thawed) in an even layer on the bottom of the slow cooker. Season with half the 1/2 tsp kosher salt and 1/4 tsp black pepper.

  4. 4

    Scatter the cooked bulk pork breakfast sausage, 1 diced red bell pepper, and 1 diced yellow onion over the hash browns.

  5. 5

    In a large bowl, whisk together 10 large eggs, 1/2 cup whole milk, 1/2 tsp garlic powder, 1/2 tsp onion powder, and the remaining kosher salt and black pepper until well combined.

  6. 6

    Pour the egg mixture evenly over the layered ingredients. Sprinkle 2 cups shredded sharp cheddar cheese on top.

  7. 7

    Cover and cook on LOW for 3.5 to 4 hours, or until the eggs are fully set in the center and the internal temperature of the egg casserole reaches 160°F (71°C). Do not cook on HIGH or the eggs will become rubbery.

  8. 8

    Turn off the slow cooker, remove the lid, and let the casserole rest for 10 minutes before scooping and serving.

Questions

Can I make Slow Cooker Breakfast Sausage Egg Casserole dairy-free?

Yes. The dairy in this entry is 1/2 cup whole milk, 2 cups sharp cheddar cheese, shredded. Swap the milk for unsweetened oat or soy milk; the cheese for a plant-based melting cheese (expect a milder flavor). The richness shifts slightly, but the method does not change.

Can I make Slow Cooker Breakfast Sausage Egg Casserole ahead?

Yes, it takes well to being made ahead. Refrigerate leftovers within two hours and eat them within three days. Reheat gently on the stovetop. It also freezes well for up to three months.

Can I halve or double Slow Cooker Breakfast Sausage Egg Casserole?

Yes. As written it serves 6. Every ingredient in this entry carries precomputed half and double quantities, and the app's batch dial rewrites them inside each step. Keep the slow cooker between half and two-thirds full; the cook time stays roughly the same.
