Ingredients

Bread and Fruit

8 cups day-old bread cubes (preferably brioche or challah)
2 cups fresh or frozen blueberries
1 tbsp lemon zest (optional)

Custard

6 large eggs
2 cups whole milk
1 cup heavy cream
¾ cup granulated sugar
2 tsp pure vanilla extract
½ tsp ground cinnamon
Pinch of salt

Topping

½ cup brown sugar
¼ cup all-purpose flour
4 tbsp cold unsalted butter, cut into small cubes
Optional: ½ tsp ground nutmeg or ¼ cup chopped nuts

Substitution Notes:

Milk can be replaced with almond, oat, or soy milk for dairy-free options
Bread can be whole wheat or gluten-free; adjust custard for absorption
Butter can be replaced with vegan butter for plant-based variations

Step-by-Step Instructions

Step 1: Prepare the Bread and Pan

Grease a 9×13-inch baking dish lightly with butter or non-stick spray. Arrange bread cubes evenly in the pan, ensuring they are spread out for even custard absorption. Scatter blueberries over the top and lightly sprinkle with lemon zest if using.

Step 2: Make the Custard

In a large mixing bowl, whisk together eggs, milk, heavy cream, granulated sugar, vanilla extract, cinnamon, and salt. Whisk until smooth and well combined, ensuring no lumps remain. The custard should be well-incorporated for a creamy, uniform texture in the casserole.

Step 3: Combine Bread and Custard

Pour the custard mixture evenly over the bread and blueberries, pressing gently with a spatula so the bread absorbs the custard. If preparing as an Overnight Blueberry French Toast, cover tightly with plastic wrap and refrigerate for at least 8 hours. This allows the flavors to meld and bread to soak thoroughly.

Step 4: Prepare the Topping

In a small bowl, combine brown sugar, flour, and cubed cold butter. Use a pastry cutter or your fingers to blend until the mixture is crumbly. Sprinkle evenly over the soaked bread and blueberries, creating a sweet, crunchy topping.

Step 5: Bake the Casserole

Preheat the oven to 350°F (175°C). Bake uncovered for 45-50 minutes, or until the custard is set and the topping is golden brown. A knife inserted into the center should come out clean. For Frozen French Toast Casserole, allow to thaw overnight in the fridge before baking and increase baking time slightly.

Step 6: Rest and Serve

Allow the casserole to rest for 5-10 minutes after baking. This helps the custard firm up slightly and makes slicing easier.

How to Serve

Cut into squares and serve warm on plates.
Drizzle with maple syrup, berry compote, or a dusting of powdered sugar.
Pair with fresh fruit or a simple green salad for a balanced Breakfast Fruit Ideas Brunch spread.
Ideal for Brunch Sandwich preparation by slicing into layers and adding yogurt or cream cheese.
For holiday gatherings, present in the baking dish for a rustic, inviting display.

Additional Tips

Use day-old or slightly stale bread for optimal custard absorption.
Press down the bread gently when adding custard to ensure even soaking.
For a richer topping, add chopped nuts or a light sprinkle of cinnamon sugar.
Use frozen blueberries directly; they will release juices during baking for natural sweetness.
If using an Overnight Blueberry Cheesecake French Toast version, layer cream cheese dollops between bread layers before pouring custard.
