Ingredients:
- 1 pack (8 ounces) softened cream cheese
- 1 cup powdered sugar
- 2 tablespoons milk
- 1 tablespoon vanilla extract, split
- 2 cups blueberries, divided
- 2 loaves (about 1 pound each) cubed French bread
- 2 cups milk
- 8 large eggs
- 1 teaspoon cinnamon powder
- 1/2 teaspoon ground nutmeg
Preparing the Cream Cheese Mixture
Step 1: Create a Smooth and Sweet Base
Begin extract by taking your softened cream cheese and placing it in a medium-sized mixing bowl. Softened cream cheese is crucial here; if it’s too cold, it will be lumpy and difficult to incorporate smoothly. You can leave it out on the counter for about an hour or gently warm it in the microwave for 15-20 second intervals, being careful not to melt it. Next, add the powdered sugar to the bowl with the cream cheese. Using an electric mixer, beat the cream cheese and powdered sugar together until the mixture is light, fluffy, and completely smooth. This process can take about 2-3 minutes. Scrape down the sides of the bowl occasionally to ensure everything is well combined. This sweet, creamy layer will form the decadent foundation of our casserole.
Step 2: Infuse with Vanilla and Milk
Now, it’s time to add some moisture and flavor to our cream cheese mixture. Add 1 tablespoon of milk and half of the vanilla extract (which is 1/2 tablespoon) to the bowl. Continue to beat with your electric mixer on low speed until everything is just combined. Overmixing at this stage can make the cream cheese mixture too thin. You want it to be spreadable but still hold its shape somewhat. The goal is to achieve a luscious, spreadable consistency that will coat the bread beautifully. This subtle addition of vanilla and milk will enhance the overall flavor profile of the casserole.
Assembling the Overnight Blueberry French Toast Casserole
Step 3: Layering the French Bread and Cream Cheese
Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish. Now, take about half of your cubed French bread and spread it evenly in the bottom of the prepared baking dish. Dollop about half of the cream cheese mixture over the bread cubes. Using a spoon or a small offset spatula, gently spread the cream cheese mixture over the bread. Don’t worry if it’s not perfectly uniform; some pockets of pure cream cheese will be delightful. Then, sprinkle about half of your fresh blueberries (which is 1 cup) over the cream cheese layer. If you are using frozen blueberries, you can add them directly without thawing, but be aware that they might release more liquid.
Step 4: Building the Second Layer and Adding More Berries
Repeat the layering process. Add the remaining half of the cubed French bread on top of the cream cheese and blueberry layer. Again, gently press down to create a relatively even surface. Now, dollop the remaining cream cheese mixture over this second layer of bread. Spread it out as best as you can, aiming for coverage without pressing too hard, which could make the bread mushy. Finally, sprinkle the remaining 1 cup of blueberries over the top. This generous amount of blueberries ensures a burst of fruity flavor in every bite.
Creating the Custard and Overnight Soaking
Step 5: Whisking the Rich Custard Mixture
In a separate large bowl, crack all 8 large eggs. Add the remaining 2 cups of milk, the remaining 1/2 tablespoon of vanilla extract, the 1 teaspoon of cinnamon powder, and the 1/2 teaspoon of ground nutmeg. Whisk everything together vigorously until the eggs are completely beaten and the mixture is homogenous. You want to ensure the spices and vanilla are evenly distributed. This custard is what will soak into the bread and bind everything together, creating that signature French toast texture.
Step 6: Soaking the Casserole for Maximum Flavor
Pour the egg custard mixture evenly over the assembled bread and berry layers in the baking dish. Gently tilt the dish to ensure the custard distributes and seeps down into all the nooks and crannies of the bread. Once the custard is poured, cover the baking dish tightly with plastic wrap or aluminum foil. Place the casserole in the refrigerator to soak overnight, for at least 8 hours, or ideally, up to 24 hours. This overnight soaking is essential for the bread to absorb the custard completely, resulting in a tender, moist, and flavorful French toast casserole. The longer it soaks, the better the texture will be.
Baking to Golden Perfection
Step 7: Baking the Casserole
When you’re ready to bake, remove the casserole from the refrigerator about 30 minutes before you plan to bake it to allow it to come to room temperature slightly. Remove the plastic wrap or foil. Bake in the preheated 350°F (175°C) oven for 45-55 minutes, or until the casserole is puffed, golden brown, and set in the center. A knife inserted near the center should come out mostly clean. If the top starts to brown too quickly, you can loosely tent it with aluminum foil. Let the casserole cool for about 10-15 minutes before serving to allow it to set up properly. This makes it easier to serve and prevents it from falling apart. Serve warm with your favorite toppings like maple syrup, whipped cream, or extra berries.

Q: Can I make the Overnight Blueberry French Toast Casserole ahead of time for more than one night?
A: Yes, you can generally prepare the Overnight Blueberry French Toast Casserole up to two nights in advance. Ensure it’s covered tightly and stored in the refrigerator. You might need to add a few extra minutes to the baking time if it’s been refrigerated for longer than 24 hours, as it will be colder. Just keep an eye on it!
Q: What type of bread works best for this recipe?
