Description

This overnight breakfast casserole is a perfect, easy-to-make dish for busy mornings. Packed with berries, bread, applesauce, and a touch of sweetness from maple syrup, it’s a delicious and nutritious way to start the day. Simply prepare it the night before, refrigerate, and bake in the morning for a hassle-free breakfast!


Ingredients

Scale
  • 6 cups mixed berries (about 32 oz), such as blueberries, strawberries, and raspberries
  • 1 lb thick bread (such as French bread, brioche, or whole wheat bread), cubed
  • 1 ⅓ cups applesauce (or mashed banana as a substitute)
  • ⅔ cup milk (of your choice, such as dairy, almond, or oat milk)
  • ⅔ cup egg whites (or additional milk of choice for a vegan option)
  • ¼ cup pure maple syrup (or substitute with agave or honey)
  • 1 teaspoon pure vanilla extract (optional)

Instructions

  1. Prepare the Bread:

    • Cube the bread into small, bite-sized pieces and spread them evenly in a greased 9×13-inch baking dish.
  2. Layer the Berries:

    • Scatter the mixed berries over the cubed bread. You can use fresh or frozen berries—just make sure to thaw the frozen ones before using.
  3. Make the Custard:

    • In a large mixing bowl, whisk together the applesauce (or mashed banana), milk, egg whites (or extra milk), maple syrup, and vanilla extract (if using).
  4. Pour Over the Bread and Berries:

    • Pour the custard mixture evenly over the bread and berries, making sure to soak all the bread pieces.
  5. Refrigerate Overnight:

    • Cover the baking dish with plastic wrap or foil and refrigerate it overnight (or for at least 6 hours) to allow the bread to absorb the custard mixture.
  6. Bake:

    • The next morning, preheat the oven to 350°F (175°C). Remove the casserole from the refrigerator and let it come to room temperature while the oven heats.
    • Bake for 45-55 minutes, or until the casserole is golden on top and a knife inserted into the center comes out clean.
  7. Serve:

    • Let the casserole cool slightly before cutting into servings. Serve warm, and optionally top with extra fresh berries or a drizzle of maple syrup.

Notes

  • You can customize this casserole by adding other fruits, such as bananas, peaches, or apples, or by sprinkling some cinnamon or nutmeg for extra flavor.
  • If you want a crispier top, leave the casserole uncovered for the last 10 minutes of baking.
  • This recipe can also be made vegan by using plant-based milk and egg replacement (such as flax eggs or additional applesauce).
