A rich and comforting blueberry French toast casserole featuring layers of custard-soaked bread, pockets of sweet cream cheese, and bursts of juicy blueberries. This make-ahead breakfast bake is perfect for holidays or relaxed weekend mornings.

Ingredients

  • 8 oz cream cheese, softened
  • 1 cup powdered sugar
  • 2 tablespoons whole milk
  • 1 tablespoon vanilla extract, divided
  • 1 cup blueberries (for cream cheese layer)
  • 2 loaves French bread (12–14 inches each), cubed (approx. 10–12 cups)
  • 2 cups milk
  • 8 large eggs
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1 cup blueberries (for topping)

Instructions

  1. In a medium bowl, blend 8 oz softened cream cheese, 1 cup powdered sugar, 2 tablespoons milk, and 1/2 teaspoon vanilla extract until smooth.
  2. Gently fold in 1 cup blueberries into the cream cheese mixture.
  3. Butter a 10×14-inch baking dish and add half of the cubed bread as the bottom layer.
  4. Spread the cream cheese mixture evenly over the bread.
  5. Top with the remaining bread cubes to form the second layer.
  6. In another bowl, whisk 2 cups milk, 8 eggs, 1 teaspoon cinnamon, 1/2 teaspoon nutmeg, and the remaining 1/2 teaspoon vanilla extract until fully combined.
  7. Pour the custard mixture evenly over the bread layers, pressing down slightly to soak.
  8. Sprinkle 1 cup blueberries evenly over the top.
  9. Cover the dish tightly with aluminum foil and refrigerate for at least 8 hours or overnight.
  10. Remove the dish from the fridge 30–60 minutes before baking.
  11. Preheat the oven to 375°F (190°C).
  12. Bake covered for 45 minutes, then uncover and bake for another 30 minutes until golden and the center is set.
  13. Let cool slightly before serving.

Notes

  • Use day-old or slightly dried bread for best texture.
  • Frozen blueberries can be used without thawing.
  • Substitute cream cheese with mascarpone or ricotta if preferred.
  • For a sweeter finish, drizzle with vanilla glaze (1 cup powdered sugar + 2 tablespoons milk + 1/2 teaspoon vanilla).
  • Use a 9×13-inch dish if needed and extend bake time by 5–10 minutes.
