This Best Overnight Sausage and Egg Casserole is a hearty and delicious breakfast dish perfect for busy mornings or brunch gatherings. Layers of cubed sourdough bread, savory cooked sausage, and melted cheddar cheese are soaked overnight in an egg and milk mixture flavored with ground mustard, salt, and pepper, then baked to golden perfection. The overnight soaking ensures a moist, cohesive texture with rich flavors in every bite.

Ingredients

Scale

Base

  • 6 cubed slices of bread (e.g., Pepperidge Farms Sourdough loaf)

Meat and Cheese

  • 1 pound cooked and drained sausage
  • 2 cups grated cheddar cheese

Egg Mixture

  • 8 large eggs
  • 2 cups milk
  • 1 teaspoon ground mustard
  • 1 teaspoon salt
  • Pepper to taste

Instructions

  1. Prepare the Baking Dish: Preheat your oven to 325°F (163°C). Grease a 9×13 inch baking dish to prevent sticking. Evenly spread the cubed bread across the bottom of the dish. Using a sturdy bread like Pepperidge Farms Sourdough helps maintain the texture during baking.
  2. Add the Sausage and Cheese: Sprinkle the cooked and drained sausage evenly over the bread layer. Then, distribute the grated cheddar cheese evenly on top of the sausage, ensuring complete coverage for balanced flavor throughout.
  3. Mix the Egg Mixture: In a large measuring cup, whisk together the eggs, milk, ground mustard, salt, and pepper until the mixture is smooth and well combined. This will act as the binder and infuse flavor into the casserole.
  4. Assemble and Chill: Pour the egg mixture evenly over the layers of bread, sausage, and cheese in the baking dish. Cover the dish tightly with plastic wrap or foil and refrigerate overnight. This allows the bread to absorb the liquid, creating a cohesive, custard-like casserole texture.
  5. Bake the Casserole: Remove the casserole from the refrigerator and place it in the preheated oven. Cover loosely with aluminum foil for the first 30 minutes to prevent over-browning. Bake for 45 to 55 minutes total, removing the foil halfway through to allow the top to brown nicely. Test doneness by inserting a fork or knife into the center; it should come out clean and the eggs set.
  6. Serve: Let the casserole cool slightly before slicing. Serve warm for a satisfying breakfast or brunch option that feeds a crowd.

Notes

  • Use a sturdy bread like sourdough to prevent sogginess.
  • For a spicier version, add chopped jalapeños or hot sausage.
  • Vegetarians can substitute sausage with cooked mushrooms or plant-based sausage.
  • The casserole can be baked immediately if short on time, but results won’t be as cohesive.
  • Leftovers keep well refrigerated for up to 3 days and reheat nicely.
  • Adjust seasoning to taste; consider adding herbs like thyme or paprika for extra flavor.
