Ingredients

Scale
  • 6 large croissants, preferably day old, torn into chunks
  • 8 large eggs, room temperature
  • 2 cups whole milk or half-and-half, room temperature
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon salt
  • 1/4 teaspoon freshly ground black pepper
  • 1/4 teaspoon smoked paprika (optional)
  • 1 1/2 cups shredded sharp cheddar cheese
  • 1/2 cup shredded Gruyère cheese (optional)
  • Optional add-ins:
  • 1 cup cooked breakfast sausage or bacon, chopped
  • 1/2 cup finely chopped green onions or chives
  • 1/2 cup sautéed spinach or mushrooms

Instructions

  1. Preheat oven to 350°F (175°C).
  2. Tear croissants into roughly 2-inch pieces and spread evenly in a greased 9×13 inch baking dish. Sprinkle cooked sausage, bacon, or veggies over croissants if using.
  3. In a large bowl, whisk 8 eggs until smooth. Slowly whisk in 2 cups whole milk or half-and-half, Dijon mustard, salt, black pepper, and smoked paprika if using until combined and slightly frothy.
  4. Stir in shredded sharp cheddar and Gruyère cheese into the custard mixture.
  5. Pour custard-cheese mixture over croissants, gently pressing down to help croissants absorb the liquid.
  6. Let the bake rest for 10-15 minutes to soak up the custard.
  7. Bake uncovered for 40-45 minutes until the top is golden brown and set in the middle. Tent with foil if browning too quickly.
  8. Cool for 5 minutes before serving.

Notes

Use room temperature eggs and milk for best custard texture. Let the bake rest before baking to allow croissants to soak custard. Sauté vegetables before adding to avoid sogginess. Rotate bake halfway if oven heats unevenly. For crispier edges, toast croissant pieces beforehand or dot with butter. Can be made dairy-free or gluten-free with substitutions.
