Ingredients
- 1 loaf (14–16 oz) of day-old French bread or brioche, cut into 1-inch cubes
- 1 ½ cups fresh or frozen blueberries
- 8 large eggs
- 2 ½ cups whole milk (or half and half)
- ½ cup heavy cream
- ¾ cup granulated sugar
- 1 tablespoon vanilla extract
- 1 teaspoon ground cinnamon
- Pinch of salt
- 3 tablespoons butter, melted (for brushing or drizzling)
Optional Topping:
- Powdered sugar
- Maple syrup
- Extra blueberries
Instructions
1. Prep the Bread
Grease a 9×13-inch baking dish with butter or nonstick spray. Spread the cubed bread evenly in the pan, then sprinkle the blueberries throughout the bread.
2. Make the Custard
In a large mixing bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla, cinnamon, and salt until fully combined.
3. Assemble the Casserole
Pour the custard mixture evenly over the bread and blueberries. Lightly press the bread down with a spatula to help it absorb the liquid. Cover with foil and refrigerate for at least 2 hours—or overnight.
4. Bake
Preheat the oven to 350°F. Remove the casserole from the fridge while the oven heats. Bake covered for 30 minutes, then uncover, brush with melted butter, and bake an additional 20–25 minutes until the top is golden and the center is set.
5. Serve Warm
Dust with powdered sugar, drizzle with maple syrup, and top with more blueberries if desired. Serve warm and enjoy every cozy, blueberry-packed bite!
Make-Ahead Tips
- Overnight Option: Assemble the casserole the night before and refrigerate. Just pop it into the oven in the morning!
- Freezer Friendly: You can freeze the unbaked casserole (without the blueberries) for up to 1 month. Thaw overnight in the fridge, add blueberries, and bake as directed.
- Leftovers: Store leftovers in the fridge for up to 4 days. Reheat in the microwave or oven.

Variations
