Step-by-Step Guide to the Best Overnight Blueberry French Toast Casserole

Tools You’ll Need

• Baking dish (9×13-inch)
• Large mixing bowl
• Whisk
• Measuring cups and spoons
• Knife
• Cutting board
• Oven
• Cooking spray

Step 1: Preparation for the Overnight Blueberry French Toast Casserole

Ingredients:

• Cooking spray
• 1 (14- to 16-oz.) loaf challah, cut into 2-inch cubes
• 1 1/2 cups fresh blueberries
• 8 oz. cream cheese, at room temperature
• 8 large eggs
• 2 1/2 cups half-and-half
• 1/2 cup granulated sugar
• 2 tablespoons granulated sugar (for topping)
• 1 tablespoon vanilla extract
• 1 teaspoon ground cinnamon
• 1/4 teaspoon salt
• 1 1/2 cups maple syrup
• 2 cups fresh blueberries, divided
• Finely grated zest and juice of 1 lemon
• Pinch of salt

Step 2: Cooking the Overnight Blueberry French Toast Casserole

Start by lightly coating a 9×13-inch baking dish with cooking spray. Spread two-thirds of the bread cubes into the dish, sprinkle the blueberries over the bread, and then add the remaining bread cubes on top. Tuck small spoonfuls of cream cheese between the bread cubes throughout the dish.

In a large bowl, whisk the eggs until smooth, then add the half-and-half, 1/2 cup sugar, vanilla, cinnamon, and salt. Whisk again to combine thoroughly. Slowly pour this custard mixture evenly over the bread, ensuring it soaks in thoroughly. Cover the dish and refrigerate overnight.

Step 3: Assembling and Finishing

In the morning, preheat your oven to 350°F. Remove the casserole from the fridge and let it sit at room temperature for about 15 minutes. Sprinkle the top with the remaining 2 tablespoons of sugar. Bake the casserole uncovered for 45 to 50 minutes, until it is puffed, golden, and set. A knife inserted in the center should come out moist but clean. Allow the casserole to cool for 20 minutes on a wire rack before serving.

To make the blueberry-maple syrup, combine the maple syrup and 1 cup of blueberries in a small saucepan. Bring to a boil over medium-high heat, reduce the heat, and simmer for 10 minutes while stirring occasionally. Remove the saucepan from the heat and stir in the remaining 1 cup of blueberries, lemon zest, lemon juice, and a pinch of salt. Serve the casserole warm with the syrup poured over the top.
