How to Make Blueberry French Toast Casserole

Making this Blueberry French Toast Casserole is a breeze, especially when you follow these simple steps. Trust me, the aroma that fills your kitchen will have everyone excited. Let’s dive into the process:
- Start by spraying a 9×13-inch baking pan with nonstick cooking spray. This will ensure your casserole comes out easily without sticking.
- Using a large serrated knife, gently slice the brioche bread into 1-inch cubes. Make sure to cut through the soft bread carefully to keep the cubes intact.
- Spread half of the brioche cubes evenly across the bottom of the prepared baking dish. This will be the base of your casserole.
- Sprinkle half of the blueberries on top of the bread cubes, distributing them evenly to ensure everyone gets some in their serving.
- Top with the remaining brioche cubes, layering them on top of the blueberries for a beautiful presentation.
- Finish with the rest of the blueberries, making sure they’re spread out for an even look.
- In a large bowl, add the lemon zest and brown sugar. Using your fingertips, rub the lemon zest into the sugar until well combined and fragrant. This step enhances the flavors.
- Now, add the eggs, milk, melted butter, vanilla, and a pinch of salt to the bowl. Whisk everything together until well combined, creating a rich custard.
- Slowly pour the egg mixture evenly over the bread and blueberries, making sure to cover all the bread cubes.
- Cover the dish tightly with foil and refrigerate for at least 4 hours or overnight. This soaking time allows the bread to absorb the custard fully.
- When you’re ready to bake, preheat the oven to 350°F (175°C). Remove the pan from the refrigerator and allow it to sit at room temperature while the oven preheats.
- Bake covered for 45 minutes. This allows the casserole to cook evenly without burning the top.
- After 45 minutes, remove the foil and continue to bake uncovered for another 10 to 15 minutes, or until the casserole is puffed and the custard in the center is cooked through. You’re looking for a golden top.
- Once done, take it out and allow it to cool slightly before serving. You can serve it warm with maple syrup or a dusting of powdered sugar for added sweetness.
Things Worth Knowing
- Soaking Time is Key: Make sure to let your casserole soak for at least 4 hours, or preferably overnight. This allows the bread to absorb all the custard mixture for a deliciously moist dish.
- Room Temperature Matters: Letting your casserole sit at room temperature for a bit before baking helps it cook evenly.
- Watch the Bake: Every oven is different, so keep an eye on your casserole towards the end of the baking time to prevent overcooking or burning.
- Cool Before Serving: Allowing the casserole to cool for about 10 minutes after baking makes it easier to cut and serve.
