Why This Recipe Works

The overnight soak allows the bread to absorb the custard fully, resulting in creamy, flavorful bites.
Using stale bread helps maintain structure during baking, ensuring the casserole doesn’t become mushy.
A mix of blueberries brings vibrant color and antioxidant benefits, adding sweetness and tartness.
Adding vanilla and cinnamon enhances the overall flavor profile, making every bite comforting and familiar.

Ingredients Breakdown

Bread (450 g / 1 lb challah or French bread): A richer bread will yield a more flavorful and custardy base. You can use stale bread for the best texture.
Milk (480 ml / 2 cups whole milk): Whole milk creates a luscious base for the custard. For a lighter option, you can substitute with 2% milk, but the consistency will change slightly.
Eggs (5 large): Provides structure and richness. Substituting eggs can alter the texture considerably, especially for this casserole.
Blueberries (300 g / 2 cups fresh or frozen): Fresh blueberries burst beautifully but feel free to use frozen to save time.
Sugar (100 g / ½ cup granulated sugar): Sweetens the dish; brown sugar is an alternative if you want a deeper flavor.
Vanilla extract (2 tsp): It enhances the dish’s flavor; skip this, and you miss the comforting depth.
Cinnamon (1 tsp): Adds warmth; adjust to taste or omit if preferred.

Essential Equipment

9×13-inch baking dish: The size is crucial to hold all ingredients without overflow.
Mixing bowls: For effectively combining the custard ingredients.
Whisk: Makes combining eggs and milk easy and efficient.
Tin foil: To cover the casserole while baking, ensuring it doesn’t over-brown.

Step-by-Step Instructions

Prep Time: 15 minutes
Cook Time: 45 minutes
Inactive Time: 8 hours (if soaking overnight)
Total Time: 9 hours

Step 1: Prepare the Bread

Cut 450 g (1 lb) of stale bread into 1-inch cubes. If the bread is fresh, toast it lightly first to prevent it from getting too soggy. Place the cubes in a 9×13-inch baking dish, spreading them evenly.

Step 2: Mix the Custard

In a large mixing bowl, whisk together 480 ml (2 cups) of whole milk, 5 large eggs, 100 g (½ cup) of granulated sugar, 2 tsp of vanilla extract, and 1 tsp of cinnamon until fully combined. Make sure there are no visible egg streaks.

Step 3: Combine Bread and Custard

Pour the custard mixture over the bread cubes. Use a spatula to gently toss, ensuring all pieces are coated. Let it sit for 15 minutes for the bread to soak up some of the mixture.

Step 4: Add Blueberries

Sprinkle 300 g (2 cups) of fresh or frozen blueberries over the top of the casserole. Gently push some berries down into the bread for even distribution.

Step 5: Chill Overnight

Cover the baking dish with plastic wrap or tin foil, and refrigerate it for at least 8 hours (or overnight). This soaking time allows the flavors to meld beautifully.

Step 6: Bake the Casserole

Preheat the oven to 175°C (350°F). Remove the casserole from the refrigerator and uncover it. Bake for 45 minutes, or until it’s puffed, golden brown, and an internal temperature of 74°C (165°F).

Step 7: Cool and Serve

Once baked, let the casserole cool for 5–10 minutes before serving. This will help it set and be easier to slice.

Expert Tips & Pro Techniques

Avoiding sogginess: Ensure your bread is stale or lightly toasted before soaking.
Make-ahead option: Prepare the casserole the night before for an easy breakfast option.
Cooking in batches: If you have a smaller oven, consider baking in two smaller dishes to ensure even cooking.
Common mistake: Avoid skipping the overnight refrigeration; it’s essential for texture and flavor.

Storage & Reheating

Refrigerator: Store leftovers in an airtight container for up to 3 days.
Freezer: The casserole can freeze well for up to 2 months. Cut it into portions, wrap them in plastic wrap, and place them in a freezer bag.
Reheating: To heat, bake in a 175°C (350°F) oven for 10–12 minutes. Avoid microwaving — it makes the crust soggy.

Variations & Substitutions

Gluten-Free Version: Use a certified 1:1 gluten-free bread blend. The baking time may increase by 5 minutes.
Vegan Version: Replace eggs with 1 cup of silken tofu blended smooth and use almond milk instead of dairy.
Mixed Berries: Substitute blueberries with raspberries or strawberries, adjusting the quantity as needed for flavor and texture.
Chocolate Chip: Add chocolate chips with blueberries for a decadent twist. Maintain the quantity of berries.
