Prepare this easy Overnight Blueberry French Toast Casserole the night before for a stress-free, delicious breakfast or brunch. It features soft bread soaked in a cinnamon-vanilla custard with juicy blueberries, ready to bake in the morning.

Ingredients

Scale
  • 1 loaf (about 1 pound) French bread or challah, cut into 1-inch cubes
  • 2 cups fresh or frozen blueberries
  • 8 large eggs
  • 2 cups milk (whole or 2%)
  • 1/2 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/4 cup butter, melted (for topping)
  • 1/4 cup maple syrup (for serving)
  • Powdered sugar (for dusting)

Instructions

  1. Lightly grease a 9×13 inch baking dish. Arrange the cubed bread evenly in the prepared dish. Sprinkle the blueberries over the bread cubes.
  2. In a large bowl, whisk together the eggs, milk, granulated sugar, vanilla extract, cinnamon, and nutmeg until well combined. This creates your creamy custard base.
  3. Slowly pour the egg mixture evenly over the bread and blueberries in the baking dish, pressing down gently to help the bread absorb the liquid.
  4. Cover the dish tightly with plastic wrap. Refrigerate for at least 4 hours, or preferably overnight, to allow the bread to fully soak up the custard.
  5. When ready to bake, preheat your oven to 350 degrees F. Remove the plastic wrap. Drizzle the melted butter evenly over the top of the casserole.
  6. Bake uncovered for 45 to 55 minutes, or until the casserole is puffed, set in the center, and golden brown on top.
  7. Let the baked French toast casserole rest for 5 to 10 minutes before serving. Dust with powdered sugar and serve warm with maple syrup.

Notes

  • For a richer flavor, substitute 1/2 cup of the milk with heavy cream in the custard mixture.
  • If you want to include a cream cheese layer, mix 4 ounces of softened cream cheese with 2 tablespoons of sugar and dot small spoonfuls over the bread before pouring the custard over everything.
  • If using frozen blueberries, do not thaw them before adding them to the bread.
