Step‑by‑Step Instructions for Unbelievable Blueberry French Toast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it heats, take a moment to grease a 9×13-inch baking dish with cooking spray or butter. This crucial step ensures your Unbelievable Blueberry French Toast Casserole won’t stick, allowing for easy serving.
Step 2: Prepare the Bread and Blueberries
Next, cube your challah or brioche bread into bite-sized pieces and evenly distribute it across the greased baking dish. Then, gently scatter fresh blueberries over the bread, filling in the gaps with their vibrant sweetness. Aim for an even distribution to ensure each bite is bursting with flavor.
Step 3: Make the Custard Mixture
In a large mixing bowl, whisk together the eggs, milk, heavy cream, maple syrup, vanilla extract, ground cinnamon, and salt. Continue whisking until everything is thoroughly combined and smooth. This rich custard will provide the perfect soaking mixture for your bread, ensuring that each piece absorbs the delightful flavors.
Step 4: Soak the Bread Mixture
Pour the custard mixture evenly over the layered bread and blueberries, ensuring each piece is soaked in the creamy goodness. Use a spatula or your hands to gently press the bread down to guarantee it absorbs the liquid completely. For the best results, cover the dish with plastic wrap and refrigerate for at least 30 minutes or overnight.
Step 5: Bake the Casserole
Once your casserole has soaked, uncover it and place it in the preheated oven. Bake for 45 to 50 minutes until the top is golden brown and the custard is set. You’ll know it’s ready when you see a slight puff and a golden hue, creating a mouthwatering crust that complements the soft interior.
Step 6: Cool and Serve
After baking, remove your Unbelievable Blueberry French Toast Casserole from the oven and allow it to cool for about 10 minutes. This brief cooling time makes slicing easier and helps the casserole hold its shape. Serve warm, dusted with powdered sugar and accompanied by whipped cream or extra maple syrup if desired.

Blueberry French Toast Casserole Recipe FAQs
How do I choose the best blueberries for this recipe?
Absolutely! When selecting blueberries, look for plump and firm berries that are deep in color, as they offer the best flavor. Avoid any that have dark spots or are overly soft. Fresh blueberries are ideal, but if they’re out of season, you can use frozen blueberries—just be sure to thaw them and drain any excess moisture to prevent sogginess in your casserole.
How should I store leftovers of the Blueberry French Toast Casserole?
Very! Place any leftover casserole in an airtight container and store it in the refrigerator for up to 3 days. To reheat, warm individual portions in the microwave or pop them back into the oven at 350°F (175°C) for about 15 minutes until heated through. This keeps the texture delightful and soft!
Can I freeze Blueberry French Toast Casserole for later?
Yes, you can freeze it! To do so, cut the casserole into individual portions and wrap each piece tightly in plastic wrap or aluminum foil, then place them in a freezer-safe container. It can last for up to 1 month in the freezer. For best results when reheating, thaw overnight in the refrigerator before warming up in the oven.
What should I do if my casserole seems too soggy?
If your casserole turns out too soggy, it may be due to using overly fresh bread or not letting it soak long enough. For a future batch, always use day-old bread and make sure to refrigerate it overnight. If you’re in a hurry, at least soak for 30 minutes, and always keep an eye on the baking time to ensure it develops that lovely golden crust.
Can I customize this recipe to accommodate dietary restrictions?
Of course! If you’re looking to make adjustments, you can easily substitute dairy with almond milk or oat milk and use flax eggs for a vegan option. For gluten-free, use gluten-free bread instead of challah or brioche. Always be sure to check ingredient labels to avoid any allergies, particularly with toppings like whipped cream or store-bought syrup.
