Step‑by‑Step Instructions for Blueberry French Toast Casserole
Step 1: Prepare the Dish
Preheat your oven to 350°F (175°C). While it heats, grease a 9×13 inch baking dish with butter or cooking spray. Next, cube your day-old challah or brioche bread and evenly distribute the pieces in the bottom of the greased dish. Scatter fresh blueberries generously over the bread, ensuring a delightful burst of flavor in every bite.
Step 2: Make Custard Mixture
In a large mixing bowl, crack 6 large eggs and whisk them together. Add in 2 cups of milk, 1 cup of heavy cream, 1/2 cup of maple syrup, 1 teaspoon of vanilla extract, 1 teaspoon of ground cinnamon, and a pinch of salt. Whisk until the mixture is smooth and all ingredients are fully combined, creating a creamy custard base that will infuse the casserole with flavor.
Step 3: Combine and Soak
Pour the custard mixture over the prepared bread and blueberries, making sure to cover every piece. Gently press down on the bread to encourage it to soak in the custard. For the best results, let this sit for 30 minutes at room temperature or, even better, cover and refrigerate it overnight, allowing the flavors to meld beautifully.
Step 4: Bake
After soaking, uncover the casserole and place it in the preheated oven. Bake for 45-50 minutes or until the top is golden brown and the custard is set. You’ll see the edges puffing up slightly, and a gentle jiggle in the center indicates it’s ready. This Blueberry French Toast Casserole will fill your kitchen with an irresistible aroma.
Step 5: Serve
Once baked, remove the casserole from the oven and let it cool for about 10 minutes. This rest period allows for easier serving and enhances the texture. Slice into squares and serve warm, drizzled with additional maple syrup and topped with whipped cream if desired, transforming your breakfast table into a delightful feast!

Make Ahead Options
These Unbelievable Blueberry French Toast Casserole is a meal prep dream! You can prepare the entire casserole up to 24 hours in advance by following the initial steps and letting it soak overnight in the refrigerator. This not only saves you valuable time in the morning but also allows the flavors to meld perfectly. To maintain quality, cover the dish tightly with plastic wrap to prevent drying. When you’re ready to bake, simply preheat your oven and pop the casserole in for 45-50 minutes until golden brown. Enjoy the convenience of a delicious breakfast that feels gourmet with little effort!

Expert Tips for Blueberry French Toast Casserole
• Use Stale Bread: Day-old challah or brioche yields the best texture; avoid fresh bread to prevent sogginess.
• Don’t Skip Soaking: Allow the casserole to sit for at least 30 minutes; overnight soaking intensifies the flavors and ensures a creamier custard.
• Check Baking Time: Watch closely in the oven; you want a golden top. To avoid burning, test with a knife to see if the custard has fully set.
• Customizable Fruit: While blueberries are fantastic, feel free to swap them out; strawberries or raspberries add delicious twists to your Blueberry French Toast Casserole.
• Proper Storage: Refrigerate leftovers in an airtight container for up to three days, and reheat in the microwave or oven for a quick breakfast treat!
How to Store and Freeze Blueberry French Toast Casserole
Fridge: Store leftovers in an airtight container for up to 3 days. To reheat, warm in the microwave or at 350°F (175°C) until heated through.
Freezer: Portions can be frozen for up to a month. Wrap well in plastic wrap or foil, then place in a freezer-safe bag. Thaw in the fridge overnight before reheating.

Blueberry French Toast Casserole Recipe FAQs
How do I choose the best bread for the casserole?
Absolutely! For the perfect texture, I recommend using day-old challah or brioche bread. These breads are sturdy enough to hold up the custard without becoming soggy, ensuring a delightful crispy top and soft interior. Fresh bread may not absorb the custard properly, leading to less than ideal results.
How should I store leftover Blueberry French Toast Casserole?
For any leftovers, store them in an airtight container in the refrigerator, where they’ll stay fresh for up to 3 days. When ready to enjoy again, simply reheat in the microwave or pop it in a 350°F (175°C) oven for about 10-15 minutes until warmed through.
Can I freeze this casserole, and if so, how?
Definitely! To freeze portions for later enjoyment, first let it cool completely. Then, wrap each piece tightly in plastic wrap or aluminum foil, or place it in a freezer-safe bag. This way, they’ll last up to a month! To thaw, simply move it to the refrigerator overnight before reheating in the microwave or oven.
What if my casserole is too soggy after baking?
If you find that your Blueberry French Toast Casserole is soggy, it could be due to not using stale bread or not allowing for enough soaking time. To prevent this, be sure to use day-old bread and give it at least 30 minutes to soak — overnight soaking is even better. If it’s already baked, just allow it to cool fully before slicing to help firm up the texture a bit.
Is this dish suitable for people with allergies?
Great question! This casserole contains eggs and dairy, which are common allergens. If you’re cooking for someone with allergies, consider using dairy-free substitutes like almond milk and flax eggs in place of the eggs. Always check with your guests to ensure it’s safe for everyone to enjoy!
Can I customize the fruits in the casserole?
Very! While blueberries shine in this dish, you can certainly swap them out for other fruits. Strawberries, raspberries, or even diced peaches can make for a delicious variation! Just keep in mind that different fruits may change the cooking time slightly, so monitor the casserole closely as it bakes.
