Step‑by‑Step Instructions for Blueberry French Toast Casserole
Step 1: Prepare Cream Cheese Mixture
In a mixing bowl, combine 8 oz of softened cream cheese, 1 cup of powdered sugar, 2 tablespoons of milk, and half of the 1 tablespoon of vanilla extract. Use a hand mixer to blend until the mixture is smooth and creamy, ensuring no lumps remain. Gently fold in 1 cup of blueberries, mixing just until evenly distributed.
Step 2: Layer Bread
Take your 10×14-inch greased baking dish and arrange half of the cubed French bread, approximately 2 loaves, in a single layer at the bottom. Make sure the pieces fit snugly together for optimal soaking, creating a solid base for your Blueberry French Toast Casserole.
Step 3: Spread Cream Cheese Mixture
Evenly distribute the cream cheese mixture over the layer of bread, using a spatula to ensure every piece is covered. This layer of creamy goodness will enrich each bite, so take your time to spread it out smoothly for a delightful texture in the final casserole.
Step 4: Add Second Layer
Create a second layer by adding the remaining cubed bread on top of the cream cheese mixture. Ensure even coverage so all parts of the casserole can soak in the egg mixture later, making for a delicious, custardy Blueberry French Toast Casserole.
Step 5: Whisk Egg Mixture
In a separate large bowl, whisk together 8 large eggs, 2 cups of milk, the remaining vanilla extract, 1 teaspoon of cinnamon, and 1/2 teaspoon of nutmeg until fully blended. Pour this egg mixture over the layered bread, making sure to coat each piece thoroughly. As you pour, look for a uniform saturation, ensuring no dry patches remain.
Step 6: Top with Blueberries
Sprinkle the remaining 1 cup of blueberries evenly over the top of the casserole. This will add delightful bursts of flavor and a beautiful presentation to your Blueberry French Toast Casserole once it’s baked, so distribute them thoughtfully to avoid overcrowding.
Step 7: Refrigerate Overnight
Cover the baking dish tightly with plastic wrap or foil and refrigerate for at least 8 hours, or overnight. Allowing the casserole to soak overnight will let the flavors meld together and result in a wonderfully rich dish that is ready to bake first thing in the morning.
Step 8: Preheat Oven
When you’re ready to bake the casserole, preheat your oven to 375°F (190°C) about 30-60 minutes prior to cooking. This will ensure your Blueberry French Toast Casserole starts cooking at the right temperature for a beautifully risen, golden-brown top.
Step 9: Bake
Cover the dish with aluminum foil to prevent over-browning and bake for 45 minutes. After this time, remove the foil and bake for an additional 30 minutes, or until the casserole is set and the top is a lovely golden brown. Look for a puffed appearance as a cue for doneness.
Step 10: Serve
Once out of the oven, allow your Blueberry French Toast Casserole to cool slightly before serving. This brief resting period enhances the flavors and makes slicing easier, ensuring everyone gets a perfect piece filled with delicious blueberries and a creamy interior.

Expert Tips for Blueberry French Toast Casserole
Butter the Dish: Prevent sticking by generously buttering your baking dish, making for an easier cleanup and better texture.

Room Temperature Matters: Let the casserole sit at room temperature for 30 minutes before baking to enhance the final texture.
Check Doneness: To avoid overbaking, keep an eye on the casserole as it bakes—look for a golden-brown, puffed top.

Blueberry French Toast Casserole Recipe FAQs
How do I choose ripe blueberries for my casserole?
Absolutely! When selecting blueberries, look for firm, plump berries that are deep blue in color and free from any dark spots or wrinkles. Avoid those with green or reddish hues, as they may not be fully ripe and might taste sour. If possible, opt for organic blueberries to ensure the best flavor and freshness.
What’s the best way to store leftovers?
To store your leftover Blueberry French Toast Casserole, transfer it to an airtight container and refrigerate it. It will stay fresh for up to 2-3 days. If you have a particularly large batch, consider cutting it into individual portions for easier storage and reheating.
Can I freeze Blueberry French Toast Casserole?
Yes! You can definitely freeze this casserole. First, wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy it again, thaw it in the fridge overnight before baking.
What should I do if my casserole comes out soggy?
If your casserole ends up being soggy, it might be because the bread didn’t absorb enough of the egg mixture. To avoid this, always use day-old bread, as it’s drier and will soak up more liquid. Additionally, try letting your casserole sit at room temperature for about 30 minutes before baking. This can help improve texture.
Are there any dietary considerations for this casserole?
If you have dietary restrictions, note that this casserole contains dairy and gluten. For a gluten-free option, substitute the bread with gluten-free bread, and for a lactose-free version, use lactose-free milk and cream cheese.
