Ingredients Needed

• 6 cups mixed berries (about 32 oz)
• 1 pound dense bread
• 1 1/3 cups applesauce or mashed banana
• 2/3 cup plant-based or dairy milk
• 2/3 cup egg whites or more milk
• 1/4 cup maple syrup, agave, or honey
• 1 tsp vanilla extract (optional)

Step-by-Step Instructions

1. If your bread isn’t slightly stale, you can dry it out by baking slices at 300°F for about 15 minutes.
2. Grease a 9x13-inch baking dish. Cut the bread into cubes and spread them evenly across the bottom.
3. In a bowl, whisk together applesauce, milk, eggs (or substitute), sweetener, and vanilla. Pour this over the bread.
4. Top generously with berries, cover, and refrigerate overnight to allow the bread to soak up the mixture.
5. Preheat oven to 350°F the next morning. Bake the casserole for around an hour until golden brown and set.
