This Overnight Croissant Breakfast Casserole is a delightful make-ahead dish perfect for a weekend brunch or holiday breakfast. Layers of buttery croissants, savory sausage, and gooey cheddar cheese are soaked in a seasoned egg mixture and baked to golden perfection.

Ingredients

Scale

Croissant Layer:

  • 6 large croissants, cut into pieces

Sausage and Cheese Layer:

  • 1 lb breakfast sausage, cooked and crumbled
  • 2 cups shredded cheddar cheese

Egg Mixture:

  • 6 large eggs
  • 2 cups milk
  • 1 teaspoon dry mustard
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Instructions

  1. Prepare the Baking Dish: Grease a 9×13-inch baking dish. Place the croissant pieces evenly in the dish.
  2. Add Sausage and Cheese: Sprinkle the cooked sausage and shredded cheese over the croissants.
  3. Make the Egg Mixture: In a large bowl, whisk together the eggs, milk, dry mustard, salt, and black pepper until well combined.
  4. Assemble the Casserole: Pour the egg mixture over the croissant, sausage, and cheese layers, pressing down gently to ensure the croissants soak up the liquid.
  5. Refrigerate: Cover the dish with plastic wrap and refrigerate overnight or for at least 2 hours.
  6. Bake: Preheat the oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature while the oven heats. Bake, uncovered, for 40-45 minutes, or until the top is golden brown and the custard is set.
  7. Serve: Allow the casserole to cool for a few minutes before slicing. Serve warm.
