A delicious overnight croissant breakfast casserole with sausage and cheese, perfect for a hearty morning meal.

  • Total Time: 7 hours
  • Yield: 6 servings 1x

Ingredients

Scale
  • 5 large croissants (preferably day-old), torn into large chunks
  • 1 lb (450g) ground sausage, cooked and drained
  • 1 cup (120g) shredded cheddar cheese
  • 6 large eggs
  • 2 cups (475ml) whole milk
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • Fresh parsley, chopped (optional, for garnish)

Instructions

  1. Grease a 9×13-inch baking dish with cooking spray or butter. Layer torn croissants evenly in the dish.
  2. Sprinkle cooked sausage and shredded cheese over croissants.
  3. In a large bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and onion powder.
  4. Pour the mixture evenly over the croissant layers. Gently press down with a spatula to help the croissants soak up the custard.
  5. Cover the dish with foil and refrigerate for at least 6 hours or overnight.
  6. Preheat oven to 350°F (175°C). Uncover the casserole and bake for 40–45 minutes, or until golden brown and set in the center.
  7. Let cool for 10 minutes, then garnish with fresh parsley and serve warm.

Notes

  • Stale or toasted croissants absorb the custard better.
  • Refrigerate for at least 6 hours or overnight for best results.
  • Baking immediately may result in a soggy casserole.
  • Press down the croissants gently to ensure even soaking.
