Why This Recipe Works

Overnight soaking: Allowing the bread to soak in the custard mixture overnight enhances flavor absorption for a richer taste.
Fresh blueberries: Their burst of juiciness adds an irresistible sweetness that contrasts beautifully with the creamy base.
Bread choice: Using a sturdy bread like brioche or challah creates a perfect soft texture without falling apart.
Simple preparation: With minimal effort required, it’s a fantastic way to serve a crowd without slaving away in the kitchen.

Ingredients Breakdown

1 loaf brioche or challah (450 g, about 12 slices): This sweet bread soaks up the custard beautifully.
6 large eggs (300 g): Provide the structure and richness in the casserole.
480 ml (2 cups) whole milk: Adds creaminess; you can use almond or oat milk for a dairy-free version.
150 g (3/4 cup) granulated sugar: Sweetens the custard mixture; you can reduce the sugar a bit to suit your taste.
1 tablespoon vanilla extract: Enhances the flavor; use pure vanilla for the best results.
1 teaspoon ground cinnamon: Adds warmth and depth; feel free to increase for a spicier flavor.
450 g (3 cups) fresh blueberries: Bring natural sweetness and tartness to the dish. Frozen blueberries work too, but they may make it a bit soggier.
50 g (1/4 cup) butter: Adds richness and is used for greasing the baking dish; can be substituted with cooking spray.

Step-by-Step Instructions

Prep Time: 15 minutes
Cook Time: 45 minutes
Inactive Time: 8 hours (overnight soaking)
Total Time: 8 hours 60 minutes
Servings: 8 servings

Step 1: Prepare the Bread

Cube the bread into 1-inch pieces and place them in a large mixing bowl. This step allows for optimal soaking of the custard mixture.

Step 2: Whisk the Custard

In a separate mixing bowl, whisk together 6 large eggs, 480 ml (2 cups) of milk, 150 g (3/4 cup) of sugar, 1 tablespoon of vanilla extract, and 1 teaspoon of ground cinnamon until the mixture is well combined.

Step 3: Combine Bread and Custard

Pour the custard over the cubed bread and gently fold until all pieces are soaked. Be careful not to smash the bread.

Step 4: Add Blueberries

Fold in 450 g (3 cups) of fresh blueberries until evenly distributed. Reserve a few for topping before baking.

Step 5: Transfer to Baking Dish

Grease the 9×13-inch baking dish with 50 g (1/4 cup) of butter and pour the bread mixture into it. Spread evenly, and sprinkle the reserved blueberries on top.

Step 6: Chill Overnight

Cover with plastic wrap and refrigerate for at least 8 hours, or overnight. This step is crucial for the bread to absorb the custard fully.

Step 7: Preheat the Oven

When ready to bake, preheat your oven to 180°C (350°F).

Step 8: Bake

Remove the casserole from the fridge and let it sit at room temperature for 15 minutes. Bake for 40–45 minutes, or until the top is golden brown and the center is set at an internal temperature of 74°C (165°F).

Step 9: Serve

Once baked, let cool for 10 minutes before slicing. This step helps the casserole hold its shape better.

Expert Tips & Pro Techniques

Avoid sogginess: Make sure to use stale bread or toast fresh bread slightly to dry it out before cubing.
Make-ahead option: You can prepare the casserole the night before and simply bake it in the morning for a stress-free breakfast.
Professional technique: Consider using a slow oven (about 160°C or 325°F) for a longer bake to achieve a more tender texture; the low heat creates more gentle browning.
Common mistakes: Ensure all pieces are coated thoroughly—otherwise, you might end up with dry spots.

Storage & Reheating

Refrigerator: Store leftovers in an airtight container in the fridge for up to 3 days.
Freezer: This casserole can be frozen for up to 2 months. Wrap it tightly in plastic wrap, then in foil to prevent freezer burn. Thaw in the fridge overnight before reheating.
Reheating: Reheat in a 175°C (350°F) oven for 10–12 minutes. Avoid microwaving, as it can make the crust soggy.

Variations & Substitutions

Vegan Version: Use non-dairy milk, and replace eggs with a mixture of 1 tablespoon of ground flaxseed with 3 tablespoons of water per egg.
Chocolate Chip Add-In: Substitute 150 g of chocolate chips for half the blueberries for a richer flavor profile.
Seasonal Fruit Swap: Replace blueberries with fresh strawberries or sliced peaches for a different twist.
Gluten-Free Version: Use a gluten-free bread (like Udi’s) for a similar texture; increase baking time by 3–5 minutes.

Serving Suggestions & Pairings

Enjoy your Blueberry French Toast Casserole with a drizzle of maple syrup or a dusting of powdered sugar. Pair it with crispy bacon or fresh fruit salad for a well-rounded breakfast. For a fun brunch treat, serve alongside classic French toast or sip on a refreshing avocado toast cocktail.
