Ingredients

  • 1 loaf brioche bread, day-old
  • 2 croissants, day-old
  • 8 large eggs
  • 2 cups whole milk
  • 1 cup heavy cream
  • 3 teaspoons vanilla extract
  • ½ cup light brown sugar
  • 2 tablespoons maple syrup
  • ¾ teaspoon ground cinnamon
  • 1 teaspoon salt
  • Zest of 1 lemon
  • 1 ½ cups fresh or frozen blueberries
  • 6 ounces cream cheese cut into small cubes

For serving:

  • Fresh blueberries
  • Maple syrup
  • Confectioners sugar

Instructions

  • Grease a 9x13 inch baking pan with butter. Set aside.
  • Cut the brioche bread and croissants into 1-inch cubes.
  • Make the custard: In a bowl, whisk eggs, milk, heavy cream, vanilla extract, brown sugar, maple syrup (2 tablespoons), cinnamon, salt, and lemon zest. Set aside.
  • Assemble: Add half of the cubed brioche and croissants into the greased pan. Layer with 1 cup of blueberries and half of the cream cheese. Then, layer the remaining bread, blueberries, and cream cheese cubes, gently pressing them down to tuck under the bread.
  • Pour the custard into the casserole evenly, making sure everything is soaked nicely.
  • Refrigerate overnight: Cover with foil and refrigerate overnight. If you're planning to make it the same day, give it at least 2-3 hours.
  • Preheat oven to 350ºF. If you let it refrigerate overnight, let it sit on the counter for 30-40 minutes before baking. It will help it come closer to room temperature so it bakes faster and more evenly.
  • Bake covered for 35 minutes. Then, uncover and bake for another 18-20 minutes until golden brown on top, and the custard in the center is set. It should still be moist and jiggly, but not liquidy.
  • Let cool slightly before serving. Serve warm with fresh blueberries, a dusting of confectioner's sugar, and a few drizzles of maple syrup. Enjoy!

Notes

  • Use day-old bread. Drier bread will help soak the custard better and prevent sogginess.
  • Milk to heavy cream ratio of 2:1 is ideal for the perfect custard consistency. It will keep it moist and rich without being soggy. Try not to substitute, if possible.
  • Do not use skim milk or half-and-half.
  • If you’re planning to bake the same day, soak for at least 2-3 hours in the fridge.
  • Check doneness in the center. It should be moist and lightly jiggly, not liquidy.
  • Freezing: Freeze only after it’s baked and cooled down. It will freeze in individual portions for up to 2 months.
  • Reheating: Thaw overnight in the fridge, then bake at 350°F until warmed through.
 
Substitutions and variations
  • Bread: You can also use French bread, sourdough, or something sturdy. Don't use regular sandwich bread, as it will not soak well.
  • Blueberries: Use any berries, fresh or frozen.
  • Cream cheese: If you prefer not to use cream cheese, omit.
