What Sets This Recipe Apart

What truly sets this Overnight Blueberry French Toast Casserole apart is its simplicity and versatility. Unlike traditional French toast, which requires individual pieces to be cooked on the stovetop, this casserole allows you to prepare everything the night before. The whole wheat French bread soaks up the custard mixture beautifully, ensuring that each bite is bursting with flavor. Plus, with the addition of fresh or frozen blueberries, you get natural sweetness and a pop of color that makes this dish a feast for the eyes as well as the palate.

Gather These Ingredients

• 1 (14-16 oz) loaf whole wheat French bread, cut into 1-inch cubes – This is the base of your casserole and provides a hearty texture.
• 2 cups liquid egg whites, or 8 whole eggs – For a protein boost and creamy custard consistency.
• 2 cups unsweetened almond milk – A dairy-free alternative that keeps the dish light.
• 1/4 cup pure maple syrup – For a touch of natural sweetness.
• 1 Tbsp vanilla extract – Adds depth of flavor.
• 2 tsp cinnamon – The warm spice that enhances the overall taste.
• 1/4 tsp nutmeg – A hint of nutmeg complements the cinnamon.
• Pinch of salt – Balances the sweetness.
• 1 cup fresh or frozen blueberries – Bursting with flavor and nutrients.
• Optional toppings: powdered sugar, maple syrup, extra blueberries – For serving and a beautiful presentation.

Prep & Cook Tools

• Large mixing bowl – For combining your custard ingredients.
• 9×13-inch baking dish – Ideal size for the casserole.
• Whisk – To blend the egg mixture smoothly.
• Sharp knife – For cutting the French bread into cubes.
• Plastic wrap – To cover the casserole overnight in the fridge.
• Oven – Preheat to bake the casserole to perfection.

Make Overnight Blueberry French Toast Casserole: A Simple Method

Step 1: Prepare the Bread

Begin by cutting your whole wheat French bread into 1-inch cubes. Place the cubes in a large mixing bowl and set aside. This step allows the bread to soak up all the delicious custard mixture.

Step 2: Whisk the Custard

In a separate large mixing bowl, whisk together the liquid egg whites (or whole eggs), unsweetened almond milk, pure maple syrup, vanilla extract, cinnamon, nutmeg, and a pinch of salt. Ensure all ingredients are well combined for a smooth custard.

Step 3: Combine Bread and Custard

Pour the custard mixture over the bread cubes. Gently fold the bread into the custard until all pieces are evenly coated.

Step 4: Add Blueberries

Gently fold in the fresh or frozen blueberries, ensuring they are distributed throughout the mixture. This adds bursts of fruity flavor in every bite.

Step 5: Refrigerate Overnight

Transfer the entire mixture into a greased 9×13-inch baking dish. Cover with plastic wrap and refrigerate overnight. This allows the bread to soak up the custard fully, creating a rich and flavorful casserole.

Step 6: Bake the Casserole

The next morning, preheat your oven to 350°F (175°C). Remove the plastic wrap and bake the casserole for 45-50 minutes, or until the top is golden brown and the center is set.

Step 7: Serve and Enjoy

Once baked, allow the casserole to cool slightly before serving. Dust with powdered sugar, drizzle with maple syrup, or add extra blueberries on top for a beautiful presentation.

In-Season Swaps

• Fruits: Swap blueberries for seasonal fruits such as strawberries, raspberries, or chopped apples.
• Breads: Use challah or brioche instead of whole wheat French bread for a richer flavor.
• Milk Alternatives: Substitute almond milk with oat milk or coconut milk for different flavor profiles.
• Sweeteners: Replace maple syrup with honey or agave nectar if preferred.

Avoid These Traps

• Don’t skip the soaking time. Allowing the casserole to sit overnight is key to achieving the right texture.
• Using stale bread can yield a better texture, so don’t be afraid to use day-old French bread.
• Be mindful of the baking time. Overbaking can lead to a dry casserole, while underbaking can leave it too custardy.
• Don’t forget to grease your baking dish to prevent sticking!

Freezer-Friendly Notes

This Overnight Blueberry French Toast Casserole is also freezer-friendly! If you want to prepare it ahead of time, assemble the casserole but do not bake it. Cover tightly with plastic wrap and foil, and it can be stored in the freezer for up to 2 months. When you’re ready to serve, simply thaw it overnight in the refrigerator and bake as directed. This makes it an excellent option for meal prep or holiday gatherings.

Quick Q&A

Can I use different types of bread for this casserole?

Absolutely! While whole wheat French bread is a healthy choice, you can use any sturdy bread like challah, brioche, or even gluten-free bread if needed. Just ensure it can hold up to the custard.

Can I make this casserole without eggs?

Yes! You can substitute the eggs with a flaxseed meal or chia seed mixture (1 tablespoon of flaxseed meal or chia seeds mixed with 2.5 tablespoons of water for each egg) or use a store-bought egg replacer.

How do I store leftovers?

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through.

Can I add nuts or other toppings?

Definitely! Feel free to add chopped nuts, such as walnuts or pecans, for a crunchy texture. You can also top with yogurt or whipped cream for added indulgence.
