Ingredients

1 loaf French bread, cut into cubes

2 cups fresh blueberries

6 large eggs

1 cup milk

1/2 cup heavy cream

1/4 cup maple syrup

1 teaspoon vanilla extract

1 teaspoon ground cinnamon

1/2 teaspoon ground nutmeg

1/4 teaspoon salt

2 tablespoons butter, melted

2 tablespoons powdered sugar (optional, for serving)

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish with butter or cooking spray.

Arrange the cubed French bread evenly in the prepared baking dish. Sprinkle the blueberries over the bread cubes.

In a large mixing bowl, whisk together the eggs, milk, heavy cream, maple syrup, vanilla extract, cinnamon, nutmeg, and salt until well combined.

Pour the custard mixture evenly over the bread and blueberries, making sure all the bread is soaked. Press the bread down gently to ensure it absorbs the custard.

Cover the dish with plastic wrap and refrigerate for at least 2 hours, or overnight, to allow the bread to soak up the custard.

When ready to bake, remove the casserole from the fridge and let it sit at room temperature for 10-15 minutes.

Drizzle the melted butter over the top of the casserole and bake for 45-50 minutes, or until the top is golden and the casserole is set.

Let the casserole cool slightly before serving. Optionally, dust with powdered sugar and serve with extra maple syrup on the side.

Variations

There are a few fun ways I like to customize this casserole:

Add nuts: For a bit of crunch, I sometimes sprinkle in some chopped walnuts or pecans.

Use frozen blueberries: If fresh blueberries aren’t available, frozen ones work just as well.

Cinnamon swirl: For a deeper spice flavor, I swirl extra cinnamon and sugar between the layers of bread before soaking them in the custard.

Change the berries: This recipe is great with raspberries, blackberries, or even strawberries, depending on what’s in season.

Storage/Reheating

To store leftovers, I keep the casserole covered in the refrigerator for up to 3 days. It also reheats well! I simply warm it in the oven at 350°F (175°C) for about 10-15 minutes, or until heated through. Alternatively, I can microwave individual servings for 1-2 minutes. For an extra touch, I drizzle a little more maple syrup on top before serving.
