Ingredients

  • 2 loaves French bread cut into cubes, preferably day-old
  • 8 large eggs
  • 8 ounces softened cream cheese
  • 2 cups blueberries divided into two 1-cup portions
  • 1 cup powdered sugar
  • 2 cups milk with whole milk recommended for extra richness
  • 1 tablespoon vanilla extract divided
  • 2 tablespoons milk preferably whole milk, for the cream cheese layer
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg

Instructions

  • Beat the softened cream cheese, powdered sugar, 2 tablespoons milk, and 1 teaspoon of the vanilla extract in a mixing bowl until the filling becomes smooth, creamy, and evenly blended.
  • Fold 1 cup of blueberries into the cream cheese mixture with a gentle hand so the berries remain intact and are distributed throughout the filling.
  • Arrange half of the cubed French bread across the bottom of a 10×14-inch baking dish, forming an even layer.
  • Spread the blueberry cream cheese mixture over the bread layer, covering it as evenly as possible.
  • Place the remaining bread cubes over the cream cheese layer to create the top bread layer.
  • In a large bowl, whisk together the eggs, 2 cups milk, remaining 2 teaspoons vanilla extract, cinnamon, and nutmeg until the custard mixture is fully combined.
  • Pour the egg mixture over the layered bread, making sure the liquid reaches the bread throughout the dish.
  • Scatter the remaining 1 cup of blueberries evenly over the surface.
  • Cover the baking dish securely with aluminum foil and refrigerate for at least 8 hours or overnight.
  • Take the casserole out of the refrigerator 30 to 60 minutes before baking.
  • Preheat the oven to 375°F, or 190°C.
  • Bake the covered casserole for 45 minutes.
  • Remove the foil and continue baking for about 30 additional minutes, or until the center is set and the top is lightly browned.
  • Allow the casserole to cool slightly after removing it from the oven before serving.
