A quick and easy breakfast casserole perfect for busy mornings, made with bread, eggs, cheese, sausage, and vegetables. It can be prepared the night before and baked in the morning for a comforting, crowd-pleasing meal.

Ingredients

Scale
  • 8 cups cubed day-old French bread or sturdy white bread
  • 10 large eggs, beaten
  • 2 cups whole milk or half-and-half (can substitute almond milk for dairy-free)
  • 2 cups shredded sharp cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 1 pound breakfast sausage, cooked and crumbled (turkey sausage optional)
  • 1 cup diced bell peppers
  • 1/2 cup diced onions
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon mustard powder
  • Optional: 1/2 cup chopped fresh parsley or chives

Instructions

  1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Cook 1 pound breakfast sausage in a skillet over medium heat until browned and cooked through, about 7-8 minutes. Drain excess fat and set aside on paper towels.
  3. Using the same skillet, sauté diced bell peppers and onions for 4-5 minutes until softened but not mushy.
  4. In a large bowl, whisk together 10 large eggs, 2 cups milk or half-and-half, salt, black pepper, garlic powder, and mustard powder until combined and slightly frothy.
  5. In another large bowl, combine cubed bread, cooked sausage, sautéed vegetables, shredded cheddar, and mozzarella cheeses.
  6. Pour the egg mixture over the bread mixture and gently fold to combine. Let sit for 10 minutes to absorb the custard.
  7. Spread the mixture evenly into the greased baking dish. Cover tightly with aluminum foil.
  8. Bake covered for 40 minutes, then remove foil and bake an additional 15-20 minutes until the top is golden brown and set (a knife inserted should come out clean).
  9. Let the casserole rest for 10 minutes before serving. Garnish with chopped fresh parsley or chives if desired.

Notes

Use day-old bread to prevent sogginess. You can prepare the casserole the night before and refrigerate; add 10 extra minutes to baking time if baking from cold. Drain excess fat from sausage to avoid heaviness. Sauté vegetables for better flavor but can be added raw if short on time. Rest casserole before slicing for neat portions.
