Ingredients

Scale
  • 8 large eggs
  • 1 cup shredded cheddar cheese
  • 1/2 cup shredded mozzarella cheese
  • 1/2 pound breakfast sausage, cooked and crumbled
  • 1/2 cup milk
  • 1/4 cup diced onions
  • 1/4 cup diced bell peppers
  • 2 cups cubed bread (preferably day-old or slightly toasted)
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • Optional: chopped fresh parsley for garnish

Instructions

  1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
  2. In a large bowl, whisk together the eggs, milk, salt, black pepper, and garlic powder until well combined.
  3. Layer the cubed bread evenly in the baking dish. Sprinkle the cooked sausage, diced onions, and bell peppers over the bread.
  4. Pour the egg mixture evenly over the layered ingredients.
  5. Sprinkle shredded cheddar and mozzarella cheeses evenly on top.
  6. Bake uncovered for 35-40 minutes, or until the casserole is set and the cheese is golden and bubbly.
  7. Remove from oven and let it cool for 5 minutes before serving. Garnish with fresh parsley if desired.

Notes

For extra flavor, try adding sautéed mushrooms or swapping sausage for diced ham. This casserole can be made the night before and baked fresh in the morning for convenience.
