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, agave, or honey

1 tsp pure vanilla extract (optional)

Instructions

  1. If your bread isn’t already a bit dry, let it sit uncovered for a day or bake the slices at 300°F (150°C) for 15 minutes to dry it out.
  2. Grease a 9×13-inch pan and cut the bread into approximately 1-inch pieces. Layer the bread evenly in the pan.
  3. In a separate bowl, whisk together the applesauce, milk, egg whites, maple syrup, and vanilla (if using). Pour this mixture evenly over the bread.
  4. Spread the berries over the top of the casserole.
  5. Cover and refrigerate overnight.
  6. The next morning, preheat the oven to 350°F (175°C). Place the pan in the center rack of the oven and bake for 1 hour, or until the bread is lightly golden.
  7. Enjoy hot or cold!

Notes

  • Ensure the bread is dry to help it soak up the egg mixture better.
  • Frozen berries work well, just thaw and drain any excess liquid.
  • For a dairy-free version, use plant-based milk.
  • To make it gluten-free, use gluten-free bread.
  • You can freeze the casserole before baking for later use.
