Ingredients

Scale

For the Bake:

  • 6 large croissants, torn into bite-sized pieces
  • 2 cups (300 g) fresh blueberries (or frozen, thawed)
  • 8 large eggs
  • 1 1/2 cups (360 ml) whole milk
  • 1/2 cup (120 ml) heavy cream
  • 1/3 cup (70 g) granulated sugar
  • 1/3 cup (70 g) brown sugar
  • 1 tsp vanilla extract
  • 1/2 tsp ground cinnamon
  • 1/4 tsp salt

For the Topping:

  • 1/4 cup (50 g) granulated sugar
  • 1/4 cup (30 g) all-purpose flour
  • 1/4 cup (55 g) cold unsalted butter, cubed
  • 1/2 tsp ground cinnamon

Optional Garnishes:

  • Powdered sugar
  • Maple syrup
  • Whipped cream

Instructions

  1. Prepare the Dish:
    • Grease a 9×13-inch baking dish. Spread half of the croissant pieces evenly in the dish, followed by 1 cup of blueberries. Repeat with the remaining croissants and blueberries.
  2. Make the Custard:
    • In a large mixing bowl, whisk together the eggs, milk, cream, granulated sugar, brown sugar, vanilla, cinnamon, and salt until smooth. Pour the custard evenly over the croissants and blueberries, pressing down gently to ensure the bread absorbs the mixture. Cover and refrigerate for at least 1 hour or overnight.
  3. Preheat Oven: Preheat your oven to 350°F (175°C).
  4. Prepare the Topping:
    • In a small bowl, combine sugar, flour, cinnamon, and butter. Use a fork or your fingers to mix until crumbly. Sprinkle the topping evenly over the casserole.
  5. Bake:
    • Bake uncovered for 40-45 minutes, or until the top is golden and the custard is set.
  6. Cool and Serve:
    • Let the casserole cool for 5 minutes before serving. Garnish with powdered sugar, maple syrup, or whipped cream if desired.


Notes

  • Substitute blueberries with raspberries, blackberries, or mixed berries for variety.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven or microwave.
  • For added texture, sprinkle chopped pecans or almonds on top before baking.
