A hearty and comforting breakfast casserole featuring savory sausage, nutty Swiss cheese, and custardy bread, perfect for busy mornings or weekend brunches.

Ingredients

Scale
  • 1 pound (450 g) breakfast sausage, mild or spicy, removed from casing and crumbled
  • 2 cups (200 g) shredded Swiss cheese
  • 6 cups (about 8 slices) cubed day-old white or sourdough bread
  • 8 large eggs, room temperature
  • 2 cups (480 ml) whole milk or half-and-half
  • 1 tablespoon yellow mustard
  • 1 teaspoon onion powder
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 2 tablespoons melted butter

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. In a large skillet over medium heat, crumble and cook 1 pound (450 g) of sausage until browned and cooked through, about 8–10 minutes. Drain excess fat if necessary and set aside to cool slightly.
  3. Cut about 8 slices (6 cups/150 g) of day-old bread into 1-inch cubes and place them evenly in the greased 9×13-inch baking dish.
  4. Sprinkle the cooked sausage evenly over the bread cubes, then top with 2 cups (200 g) shredded Swiss cheese.
  5. In a large bowl, whisk together 8 large eggs, 2 cups (480 ml) whole milk or half-and-half, 1 tablespoon yellow mustard, 1 teaspoon onion powder, 1 teaspoon salt, and ½ teaspoon black pepper until well combined.
  6. Slowly pour the egg mixture evenly over the bread, sausage, and cheese layers. Press down lightly with a spatula to help the bread soak up the custard.
  7. Drizzle 2 tablespoons of melted butter over the top to encourage a golden crust while baking.
  8. Bake uncovered for 45–50 minutes until the casserole puffs up and the top turns golden brown. A knife inserted near the center should come out clean.
  9. Let the casserole sit for 5–10 minutes to set and make slicing easier before serving.

Notes

Use day-old or slightly stale bread for best custard absorption. If the top browns too quickly, tent loosely with foil after 30 minutes. The casserole can be assembled the night before and baked fresh in the morning. Sausage can be swapped for bacon, turkey sausage, or sautéed vegetables for a vegetarian version. Swiss cheese can be substituted with Gruyère, sharp cheddar, or mozzarella.
