Introduction
This Overnight Breakfast Casserole is a delicious and effortless way to start your day. Layers of slightly dried bread, fresh berries, and a custard-like mixture create a comforting and fruity breakfast that you prepare the night before. Simply bake it in the morning and enjoy warm or cold.

Ingredients
- 6 cups berries (32 oz)
- 1 lb thick bread
- 1 1/3 cup applesauce (or mashed banana)
- 2/3 cup milk (of choice)
- 2/3 cup egg whites (or additional milk of choice)
- 1/4 cup pure maple syrup (or agave or honey)
- 1 tsp pure vanilla extract (optional)
Instructions
- Step 1: If the bread is not already slightly dry or hard, let it sit uncovered for a day or bake slices at 300°F for 15 minutes to dry them out.
- Step 2: Grease a 9×13 inch baking pan. Cut the bread into approximately 1-inch pieces and spread them evenly in the pan.
- Step 3: In a bowl, whisk together applesauce, milk, egg whites, maple syrup, and vanilla extract (omit vanilla if using vanilla-flavored milk).
- Step 4: Pour the mixture evenly over the bread pieces in the pan.
- Step 5: Evenly scatter the berries on top of the custard-soaked bread.
- Step 6: Cover the pan and refrigerate it overnight to allow the flavors to meld and the bread to soak.
- Step 7: The next morning, preheat your oven to 350°F. Place the casserole in the center rack and bake for about 1 hour or until the bread is lightly golden.
- Step 8: Serve the casserole hot or cold, as preferred. Enjoy your easy, fruity breakfast!
Tips & Variations
- Use day-old or slightly stale bread to help absorb the custard better without becoming soggy.
- Swap berries with other fruits like diced apples, peaches, or pears for seasonal variation.
- For a richer texture, substitute whole eggs for egg whites.
- Add a sprinkle of cinnamon or nutmeg to the custard for a warm spice flavor.
- Drizzle extra maple syrup or honey on top before serving for added sweetness.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave until warm, or enjoy the casserole cold right from the fridge.

Can I use frozen berries for this recipe?

- 1 lb thick bread
- 1 1/3 cup applesauce (or mashed banana)
- 2/3 cup milk (of choice)
- 2/3 cup egg whites (or additional milk of choice)
- 1/4 cup pure maple syrup (or agave or honey)
- 1 tsp pure vanilla extract (optional)
Instructions
- Prepare the Bread: If the bread is not already slightly dry or stale, let it sit uncovered for a day to harden, or alternatively bake the slices in a 300°F oven for 15 minutes to dry them out.
- Assemble the Casserole: Grease a 9×13 inch baking pan. Cut the slightly dried bread into approximately 1-inch pieces and layer evenly in the pan.

- Add the Berries: Spread the 6 cups of fresh berries evenly over the custard-soaked bread layer.
- Refrigerate Overnight: Cover the pan tightly and refrigerate overnight to allow the bread to absorb the custard mixture and the flavors to meld.
- Bake the Casserole: The next morning, preheat the oven to 350°F. Place the casserole on the center rack and bake for 1 hour or until the bread is lightly golden and the custard is set.
- Serve: Enjoy the casserole warm right out of the oven or chilled, as per your preference.
