How This Recipe Comes Together
Ready to whip up this delicious casserole? The process is straightforward and flows in just a few easy steps. First, you prepare your ingredients, layering the cubed bread and fresh blueberries in a greased baking dish. Then, you whisk together the eggs, milk, and seasonings before pouring this mixture over the bread and letting it soak. After a short resting period, you pop it in the oven, allowing the magic to happen as it bakes to golden perfection. Here’s what you’ll need to create this mouthwatering dish.
Gather These Items
- 1 loaf of day-old brioche or challah bread, cubed
- 2 cups fresh blueberries
- 6 large eggs
- 2 cups milk
- 1/2 cup maple syrup
- 1 teaspoon vanilla extract
- 1 teaspoon ground cinnamon
- 1/4 teaspoon salt
- Butter or cooking spray for greasing
If you’re looking for substitutions, you could swap out the brioche for any bread you have on hand, or use frozen blueberries if fresh ones aren’t available.

Directions to Follow
- Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or cooking spray.
- Evenly distribute the cubed bread in the baking dish, then sprinkle fresh blueberries on top.
- In a large mixing bowl, whisk together the eggs, milk, maple syrup, vanilla extract, ground cinnamon, and salt until combined.
- Pour the egg mixture over the bread and blueberries. Make sure all pieces are soaked.
- Cover the dish with foil and let it sit for about 30 minutes at room temperature. For a deeper flavor, refrigerate overnight.
- Bake the casserole (covered) for about 30 minutes. Remove the foil and bake for an additional 15-20 minutes, until golden brown and set.
- Allow it to cool slightly before serving.
Best Ways to Enjoy It
This casserole shines when topped with a light dusting of powdered sugar or a drizzle of warm maple syrup. Consider adding a dollop of whipped cream or a scoop of vanilla ice cream for an indulgent touch! Pair it with crispy bacon or a refreshing fruit salad for a balanced brunch. A steamy cup of coffee or a refreshing glass of orange juice can elevate the experience even further!
How to Store
If you have leftovers (though I doubt you will!), you can store them safely in an airtight container in the refrigerator for up to three days. Reheat individual servings in the microwave, or pop the whole casserole back into a low oven until warmed through. Avoid reheating it too long to prevent drying out.
Helpful Cooking Tips
For the best flavor and texture, use bread that’s a day or two old; it absorbs the egg mixture better. If you want to make it ahead, prepare the casserole the night before and let it soak overnight in the fridge, making your morning stress-free. Also, keep an eye on the baking: every oven is different, so watch for that golden color to gauge doneness.
Recipe Variations
Feel free to get creative with this recipe! You can add chocolate chips for a double blueberry-chocolate delight, substitute the blueberries for raspberries or peaches, or add nuts for some crunch. For a healthier twist, replace half the milk with almond milk or use whole grain bread instead of brioche.
