What are the best ways to store and reheat frozen soup in a bag for optimal taste and convenience?

To store and reheat frozen soup in a bag for best taste and convenience, first cool the soup completely before freezing it in a resealable bag. Lay the bag flat to freeze for easy storage. To reheat, thaw the soup in the refrigerator overnight or in a bowl of cold water. Heat gently on the stove, stirring occasionally, until warmed through. Avoid microwaving the soup directly in the bag to prevent melting.
