Ingredients

Scale
  • 6 large croissants, preferably day-old, cut into halves or large chunks
  • 6 large eggs
  • 1½ cups half-and-half or whole milk
  • ½ cup heavy cream
  • ½ cup granulated sugar
  • 2 teaspoons pure vanilla extract
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon ground nutmeg
  • ¼ teaspoon salt
  • ¼ cup packed brown sugar
  • ¼ cup chopped pecans (optional)
  • Powdered sugar, for dusting
  • Fresh berries, for serving
  • Maple syrup, for serving

Instructions

  • Prepare the Custard:
    • In a large mixing bowl, whisk together the eggs, half-and-half, heavy cream, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined.
  • Assemble the Casserole:
    • Lightly grease a 9×13-inch baking dish with butter or non-stick spray.
    • Arrange the croissant halves or chunks in the baking dish.
    • Pour the custard mixture evenly over the croissants, ensuring all pieces are well coated. Gently press down on the croissants to help them absorb the custard.
  • Add Toppings:
    • Sprinkle the brown sugar and chopped pecans (if using) over the top of the casserole.
  • Soak:
    • Cover the baking dish with plastic wrap or foil and refrigerate for at least 2 hours, or overnight, to allow the croissants to fully absorb the custard.
  • Bake:
    • Preheat the oven to 350°F (175°C).
    • Remove the casserole from the refrigerator and let it sit at room temperature for about 30 minutes.
    • Bake, uncovered, for 35-40 minutes, or until the custard is set and the top is golden brown. If the top browns too quickly, tent with foil during the last 10 minutes of baking.
  • Serve:
    • Allow the casserole to cool for about 10 minutes before serving.
    • Dust with powdered sugar and serve with fresh berries and warm maple syrup.

Notes

  • Using day-old croissants helps them absorb the custard better without becoming too soggy.
  • For a slightly boozy flavor, consider adding a tablespoon of bourbon or Grand Marnier to the custard mixture.
  • This casserole can be prepared the night before and baked in the morning, making it convenient for entertaining.
