Ingredients:
- 1 pack (8 ounces) softened cream cheese
- 1 cup powdered sugar
- 2 tablespoons milk
- 1 tablespoon vanilla extract, split into two 1/2 tablespoon portions
- 2 cups blueberries, divided
- 2 loaves cubed French bread
- 2 cups milk
- 8 large eggs
- 1 teaspoon cinnamon powder
- 1/2 teaspoon ground nutmeg
Preparing the Cream Cheese Filling
Step 1: Create the Sweet Cream Cheese Base
First, let’s get our luscious cream cheese filling ready. In a medium-sized bowl, combine the softened cream cheese and the powdered sugar. It’s crucial that your cream cheese is properly softened, meaning it should be at room temperature and yield slightly when pressed. This will ensure a smooth, lump-free mixture. Use an electric mixer on medium speed to beat these two ingredients together until they are well combined and wonderfully creamy. This might take a minute or two. Next, add the 2 tablespoons of milk and 1/2 tablespoon of vanilla extract to this mixture. Continue to beat until everything is thoroughly incorporated and the filling is smooth and spreadable. Set this bowl aside for now; it will be a key component in creating those delightful pockets of creaminess in our French toast casserole.
Assembling the Casserole
Step 2: Building the Bread Foundation
Now, let’s get our French bread ready for its flavor transformation. If your French bread isn’t already cubed, cut it into roughly 1-inch pieces. You can do this the night before or earlier in the day to allow the bread to dry out slightly, which helps it absorb the custard mixture better and prevents the casserole from becoming soggy. Place the cubed French bread into a large mixing bowl. Next, in a separate, even larger bowl, whisk together the 8 large eggs, 2 cups of milk, 1 teaspoon of cinnamon powder, 1/2 teaspoon of ground nutmeg, and the remaining 1/2 tablespoon of vanilla extract. Whisk vigorously until these ingredients are thoroughly combined and you have a smooth, consistent custard. The spices will infuse the custard with that classic French toast aroma and flavor, making the entire dish incredibly comforting.
Step 3: Layering the Flavors
This is where the magic truly begin extracts to happen. Pour about half of the prepared custard mixture over the cubed French bread in the large bowl. Gently toss the bread cubes with a spatula or your hands to ensure each piece is coated in the liquid. You don’t want to mash the bread; just a gentle tossing motion is sufficient. Now, let this sit for about 5-10 minutes, allowing the bread to start soaking up the custard. While the bread is soaking, prepare your baking dish. Lightly grease a 9×13 inch baking dish with butter or non-stick cooking spray. Once the bread has had a chance to absorb some of the custard, carefully spoon about half of the bread mixture into the prepared baking dish, spreading it out evenly.
Step 4: Adding the Creamy and Fruity Layers
This step is all about layering in those incredible textures and flavors. Dollop spoonfuls of the prepared cream cheese filling over the layer of bread in the baking dish. Don’t worry about spreading it perfectly; random dollops will create delightful pockets of melted cream cheese as it bakes. Now, scatter about 1 cup of the blueberries over the cream cheese dollops. Gently press them down slightly into the bread. Next, add the remaining bread and custard mixture on top, ensuring you get an even distribution. Finally, scatter the remaining 1 cup of blueberries over the top of the casserole. For an extra touch, you can gently press these top blueberries down as well. This ensures they will be visible and bursting with flavor when served.
The Overnight Chill and Baking
Step 5: The Overnight Transformation
This is the critical step that makes it an “Overnight” French toast casserole! Once you have assembled the casserole in your baking dish and everything is layered, cover the entire dish tightly with plastic wrap. Refrigerate the casserole overnight, or for at least 8 hours. This allows the bread to fully absorb the custard, the flavors to meld together beautifully, and the cream cheese to firm up slightly. This overnight chilling is what ensures a perfectly tender and moist French toast casserole that’s incredibly easy to bake in the morning. It’s a fantastic make-ahead breakfast or brunch option, saving you precious time when you wake up.
Step 6: Baking to Golden Perfection
When you’re ready to bake, preheat your oven to 350°F (175°C). Remove the plastic wrap from the chilled casserole. If desired, you can sprinkle a little extra cinnamon and nutmeg on top before baking for an enhanced aroma. Place the baking dish on a baking sheet to catch any potential drips. Bake for 45-55 minutes, or until the casserole is puffed up, golden brown around the edges, and the center is set. You can insert a knife near the center; it should come out mostly clean. If the top starts to brown too quickly, you can loosely tent it with aluminum foil. Let the casserole rest for about 10 minutes after removing it from the oven before serving. This resting period allows it to set up further and makes it easier to scoop. Serve warm, perhaps with a dusting of powdered sugar, maple syrup, or a dollop of whipped cream.
