The cooking process explained
Crafting a delightful Blueberry French Toast Casserole is straightforward and requires only a few steps. You’ll begin by preparing your ingredients and then layer them beautifully. After a short soaking period to imbue the bread with the creamy egg mixture and sweet blueberries, it bakes into a golden-brown masterpiece.
Essentially, you’ll need to gather your ingredients first, prepare, and let the oven do the rest of the work. Let’s dive into what you’ll need.
What you’ll need
- 1 loaf of brioche or challah bread, cubed
- 2 cups fresh blueberries
- 6 large eggs
- 2 cups milk
- 1/2 cup maple syrup
- 1 teaspoon vanilla extract
- 1 teaspoon ground cinnamon
- Pinch of salt
- Powdered sugar for serving (optional)
When choosing your bread, opt for a high-quality brioche or challah for that delightful texture. Both provide a rich, buttery flavor that elevates the dish. If you’re feeling adventurous, you can swap in different fruits or spices for additional flavor layers!
Directions to follow
- Preheat your oven to 350°F (175°C) and grease a baking dish.
- In a large bowl, whisk together the eggs, milk, maple syrup, vanilla, cinnamon, and salt until smooth and well mixed.
- Layer the cubed bread evenly in the prepared baking dish.
- Sprinkle the fresh blueberries over the top of the bread.
- Pour the egg mixture evenly across the bread and blueberries, gently pressing down to ensure the bread is soaked.
- Let the mixture sit for about 15 minutes, allowing the bread to absorb all those delicious flavors.
- Bake for 45-50 minutes, or until the casserole is golden brown and set in the center.
- Allow it to cool slightly before serving, and for a festive touch, dust it with powdered sugar if desired.

Best ways to enjoy it
Serving this casserole is easy and versatile. You can serve it warm straight from the oven, with a dusting of powdered sugar on top for added charm. Consider adding a drizzle of extra maple syrup or a dollop of whipped cream for a decadent twist.
Accompany it with sides like crispy bacon or fresh yogurt to create a balanced meal. A fruit salad or a smoothie would also complement the dish nicely, adding a refreshing touch!
Storage and reheating tips
Leftovers can be stored in the refrigerator for up to three days in an airtight container. To reheat, simply pop it in the oven at 350°F (175°C) for about 15-20 minutes or until warmed through. If you have a larger portion, slicing it into smaller pieces can speed up the reheating process.
This casserole is best enjoyed fresh, but it can also be frozen for up to two months. To do so, ensure it’s cooled completely, then wrap it tightly in plastic wrap and foil before storing in the freezer. Thaw it overnight in the fridge before reheating.
Helpful cooking tips
- Ensure your bread is a day or two old; slightly stale bread absorbs the egg mixture better for a fluffier texture.
- For extra flavor, try adding a teaspoon of nutmeg to the egg mixture.
- If using frozen blueberries, there’s no need to thaw them — just toss them directly into the dish!
Creative twists
Feel free to get creative! You can swap out blueberries for other berries like raspberries or strawberries, or even use chopped apples with cinnamon for a fall-inspired twist. If you’re feeling adventurous, consider adding white chocolate chips or nuts for added texture and flavor.
Common questions
Can I prepare this casserole ahead of time?
Yes! You can assemble it the night before, cover it, and refrigerate until you’re ready to bake it in the morning. Allow it to sit at room temperature for about 20 minutes before popping it in the oven.
Can I use almond milk instead of regular milk?
Absolutely! Almond milk or any plant-based milk can work beautifully. Just ensure it’s unsweetened if you’re adjusting for sweetness with maple syrup.
What if I have leftover casserole?
Store leftovers in an airtight container in the fridge for up to three days. Reheat as mentioned above for a quick treat!
