Ingredients

Scale

Cream Cheese Mixture

  • 8 oz cream cheese, softened

  • 1 cup powdered sugar

  • 2 tablespoons milk (whole milk preferred)

  • 1 tablespoon vanilla extract

  • 1 cup blueberries

Bread Layers

  • 2 loaves French bread, cubed (day-old bread works best)

Egg Mixture

  • 8 large eggs

  • 2 cups milk

  • 1 tablespoon vanilla extract

  • 1 teaspoon cinnamon

  • ½ teaspoon nutmeg

  • 1 cup blueberries

Instructions

  • Prepare the cream cheese filling
    In a bowl, beat the softened cream cheese, powdered sugar, milk, and vanilla extract until smooth and creamy. Gently fold in 1 cup of blueberries. Set aside.

  • Assemble the casserole
    Lightly grease a 10×14-inch baking dish. Add half of the bread cubes to form an even layer. Spread the cream cheese mixture evenly over the bread. Top with the remaining bread cubes.

  • Make the custard
    In a large bowl, whisk together the eggs, milk, vanilla extract, cinnamon, and nutmeg until fully combined. Pour the mixture evenly over the bread layers. Sprinkle the remaining 1 cup of blueberries on top.

  • Chill overnight
    Cover tightly with aluminum foil and refrigerate for at least 8 hours or overnight. Remove from the fridge 30–60 minutes before baking.

  • Bake
    Preheat the oven to 375°F (190°C). Bake covered for 45 minutes. Remove the foil and bake for an additional 25–30 minutes, until the center is set and the top is lightly golden.

  • Serve
    Let the casserole rest for 10 minutes before slicing. Serve warm with maple syrup, powdered sugar, or fresh berries if desired.

Notes

  • Use day-old bread for better absorption and a custardy texture

  • Let it rest after baking so slices hold their shape

  • For extra richness, use whole milk or replace ½ cup with heavy cream

  • Add crunch by sprinkling sliced almonds or pecans on top before baking

  • Make it festive with lemon zest or a drizzle of blueberry sauce
