If you need a replacement for applesauce, the best option depends on why you're using it. If you want to retain the taste and flavor of applesauce, good substitutes include apple puree, mashed bananas, mashed sweet potatoes, pumpkin puree, or any other homemade fruit puree. However, if you're using applesauce as a substitute for fat or eggs in a recipe, the simplest replacements are pureed apples or Greek yogurt.
