This hearty Breakfast Casserole combines savory breakfast sausage, cubed bread, and melted Cheddar cheese baked in a creamy egg mixture. Perfect for a cozy morning meal, this dish is easy to prepare ahead and bake for a comforting and flavorful breakfast or brunch.

Ingredients

Meat

  • 1 pound breakfast sausage

Base

  • 6 slices of bread, cubed

Dairy

  • 1 1/2 cups shredded Cheddar cheese
  • 6 large eggs
  • 2 cups milk

Seasonings

  • 1 teaspoon dry mustard
  • Salt and pepper to taste

Instructions

  1. Preheat the oven: Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish to ensure the casserole doesn’t stick.
  2. Cook the sausage: In a skillet over medium heat, cook the breakfast sausage until it’s fully browned and cooked through. Drain off any excess fat to keep the casserole from becoming greasy.
  3. Assemble the casserole: Evenly spread the cubed bread on the bottom of the prepared baking dish. Layer the cooked sausage over the bread, then sprinkle the shredded Cheddar cheese on top.
  4. Mix egg custard: In a large bowl, whisk together the eggs, milk, dry mustard, salt, and pepper until fully combined and smooth. Pour this mixture evenly over the layered bread, sausage, and cheese in the baking dish.
  5. Bake the casserole: Place the dish in the preheated oven and bake for 40 to 45 minutes. The casserole is done when it is set in the center and the top has turned a light golden brown.
  6. Cool and serve: Allow the casserole to cool for a few minutes before slicing and serving for best texture and flavor.

Notes

  • You can use any type of bread, but slightly stale bread works best to soak up the egg mixture without becoming too mushy.
  • For a lower fat option, substitute turkey sausage and use low-fat milk and reduced-fat cheese.
  • Add vegetables like diced bell pepper, onions, or spinach to enhance nutrition and flavor.
  • This casserole can be prepared the night before and baked fresh in the morning for convenience.
  • Leftovers keep well refrigerated for up to 3 days and can be reheated in the oven or microwave.
