Step-by-Step: Overnight Blueberry French Toast

Step 1: Prepare the Bread and Cream Cheese Layer

Slice your challah bread into 12 thick slices—about 1 pound total. If your challah isn’t stale, you can lightly toast the slices to help them absorb the custard without falling apart. In a bowl, soften the cream cheese or mascarpone slightly, then fold in 1 cup of blueberries. Gently spread this creamy mixture evenly over half of the challah slices.

Step 2: Assemble the French Toast Layers

Place the remaining slices of challah on top of the cream cheese and blueberry–topped slices, creating sandwiches. Arrange these layered slices snugly in your 9×13 baking dish.

Step 3: Make the Custard Mixture

In a large mixing bowl, whisk together the 12 large eggs, 2 cups of milk, and 1 teaspoon vanilla extract until well blended. Pour this custard evenly over the layered challah sandwiches, pressing down gently to ensure all the bread absorbs the liquid.

Step 4: Refrigerate Overnight

Cover the baking dish tightly with plastic wrap or foil and refrigerate for at least 8 hours or overnight. This soaking time allows the bread to become perfectly custardy and flavorful.

Step 5: Prepare the Blueberry Syrup

About 30 minutes before baking, combine 1 cup granulated sugar, 2 tablespoons cornstarch, and 1 cup water in a saucepan over medium heat. Stir constantly until the mixture thickens. Add 1 cup fresh blueberries and ½ cup maple syrup, then cook for an additional 2–3 minutes until the berries soften and the syrup is glossy. Remove from heat and stir in 1 tablespoon butter for richness.

Step 6: Bake the French Toast

Preheat your oven to 350°F (175°C). Remove the baking dish from the fridge, uncover, and bake for 45 to 50 minutes, or until the top is golden brown and the custard is set.

Step 7: Serve and Enjoy

Let the French toast cool for a few minutes before slicing. Drizzle generously with the warm blueberry syrup and garnish with extra fresh blueberries if desired. Serve with a side of crispy bacon or your favorite breakfast proteins for a complete meal.

Holiday & Seasonal Touches

• Add a sprinkle of cinnamon and nutmeg to the custard mixture for cozy autumn vibes.
• Top with toasted almonds or pecans for a delightful crunch during winter holidays.
• Mix in a handful of chopped fresh mint with the blueberries for a refreshing spring twist.
• Swap blueberries for raspberries or blackberries for a summer berry variation.
• Serve alongside Triple Berry Zucchini Breakfast Bars for a berry-packed brunch spread.

Pro Tips & Notes

• Use stale bread: Slightly dried-out challah soaks up the custard better without turning mushy.
• Room temperature eggs and milk: This helps the custard mixture blend more evenly.
• Don’t skip the refrigeration: Soaking overnight ensures a custardy, creamy texture inside every slice.
• Customize your fruit: Blueberries are classic, but feel free to experiment with other berries or even diced apples.
• Make ahead syrup: The blueberry syrup can be prepared a day in advance and gently reheated before serving.

Shelf Life & Storage

Store any leftover Overnight Blueberry French Toast in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven to restore warmth and softness. The blueberry syrup keeps well separately in a sealed jar for up to 5 days in the fridge. For longer storage, both the baked french toast and syrup freeze beautifully—wrap well and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

Your Questions, Answered

Can I use a different type of bread instead of challah?

Absolutely! Brioche is a fantastic alternative since it’s similarly rich and fluffy. You can also experiment with thick slices of white sandwich bread or even a sturdy sourdough, but the texture and flavor will vary slightly.

Can I make this recipe vegan or dairy-free?

To make a dairy-free version, substitute the cream cheese with a plant-based cream cheese alternative and use your favorite non-dairy milk such as almond or oat milk. For the eggs, you can try using a commercial egg replacer or a mix of flaxseed and water, but the custard texture might be less traditional.

What’s the best way to reheat Overnight Blueberry French Toast?

For the best texture, reheat slices in a 350°F oven for about 10-15 minutes until warmed through and slightly crisp on the edges. You can also microwave individual slices for about 30-60 seconds if you’re short on time.

Can I prepare the blueberry syrup ahead of time?

Yes! The blueberry syrup can be made up to 3 days in advance and stored in the refrigerator. Reheat it gently on the stove or in the microwave before drizzling over the french toast.
