Step‑by‑Step Instructions for Overnight Blueberry French Toast Casserole
Step 1: Cream Cheese Mixture
In a mixing bowl, combine softened cream cheese, confectioners’ sugar, milk, and vanilla extract. Use a hand mixer or a whisk to blend until the mixture is silky smooth. Gently fold in one cup of fresh blueberries, making sure they’re evenly distributed throughout. This creamy filling will add a delicious richness to your Overnight Blueberry French Toast Casserole.
Step 2: Layering
Take a buttered 10×14-inch baking dish and layer half of the cubed French bread evenly across the bottom. Spread the cream cheese mixture on top of the bread, ensuring an even layer. Then, add the remaining cubes of bread on top, creating a beautiful base for your casserole. This layering is essential for a delightful texture in every bite.
Step 3: Custard Preparation
In a separate medium-sized bowl, whisk together the milk, eggs, vanilla extract, cinnamon, and nutmeg until the mixture is well blended and slightly frothy. This custard is the key to achieving that classic creamy French toast texture. Pour the custard evenly over the layered bread, taking care to soak all the pieces thoroughly for the best results.
Step 4: Assembly
After pouring the custard, sprinkle the remaining blueberries on top of the casserole. These juicy berries will burst during baking, infusing your dish with vibrant flavor. Make sure all the bread pieces are soaked in the custard as you press down gently. This step ensures every bite of the Overnight Blueberry French Toast Casserole is deliciously filled with flavor.
Step 5: Refrigeration
Cover your baking dish tightly with aluminum foil and place it in the refrigerator. Let the casserole chill for at least eight hours or overnight, allowing the bread to absorb the custard mixture. This make-ahead step is essential for a flavorful morning treat and makes your breakfast prep stress-free.
Step 6: Baking
About 30 to 60 minutes before you plan to bake, remove the casserole from the refrigerator to allow it to come to room temperature. Preheat your oven to 375°F (190°C). Bake the casserole covered with foil for 45 minutes to set the custard. Then, remove the foil and continue baking for an additional 30 minutes until the top is golden brown and the center is fully set.
Step 7: Cooling
Once baked, allow the Overnight Blueberry French Toast Casserole to cool for about 10 minutes before slicing. This brief cooling period enhances the flavors and makes serving easier. The edges will be nicely browned, and the center will be soft and custardy—perfect for a warm, indulgent breakfast with family and friends.

Make Ahead Options
These Overnight Blueberry French Toast Casserole preparations are perfect for busy home cooks! You can assemble the casserole up to 24 hours in advance by completing all the steps except baking. After layering the bread and cream cheese mixture, cover the dish tightly with aluminum foil and refrigerate it overnight. To maintain quality, ensure the casserole is tightly sealed to prevent drying out. When you’re ready to serve, remove it from the fridge about 30-60 minutes before baking, allowing it to reach room temperature. Preheat your oven and bake as directed for a delightful breakfast that’s just as delicious as if made fresh that morning!

Overnight Blueberry French Toast Casserole Recipe FAQs
What kind of bread should I use for the casserole?
Absolutely go for slightly stale French bread! It absorbs the custard beautifully without turning to mush. Avoid soft sandwich bread, as it doesn’t hold up well. If your bread is fresh, simply let it sit out for a few hours or dry it out in a low oven for 10-15 minutes before use.
How long can I store leftovers in the fridge?
You can store any leftover Overnight Blueberry French Toast Casserole in an airtight container in the refrigerator for up to 3 days. Just reheat it in the oven at 350°F (175°C) for about 20-30 minutes or until warmed through. This helps retain that lovely texture and flavor, making it feel fresh!
Can I freeze the casserole for later use?
Yes! You can absolutely freeze the Overnight Blueberry French Toast Casserole. Slice it into portions and wrap each tightly in plastic wrap, then place them in a freezer-safe bag. It will keep well for up to 2 months. To reheat, simply thaw in the refrigerator overnight, and warm in a preheated oven at 350°F for approximately 30 minutes.
I’m worried about ending up with a soggy casserole. Any tips?
Totally understandable! To avoid sogginess, be sure to use slightly stale bread, which helps it soak up the custard without oversaturating. Also, ensure you gently press down the bread pieces after pouring the custard over them, so they are well coated but not swimming in excess liquid. Baking it for the right amount of time until golden brown in the center is key!
Can my furry friends share in the breakfast joy?
While this Overnight Blueberry French Toast Casserole is a delicious treat for us, it’s best not to share it with pets. The sugar and dairy can upset their tummies. But if you want to treat them, consider plain, unsweetened, and unseasoned bread instead!
Are there any allergies I should be cautious of with this recipe?
Definitely be mindful of any potential allergies! This recipe includes common allergens like dairy, eggs, and gluten from the bread. If you’re serving guests, it’s a great idea to ask about allergies beforehand and consider swapping eggs with a suitable egg replacement and using gluten-free bread if necessary.
