Freezing Leftover Soup
Follow these tips to freeze your soup safely.
1. Cool the hot soup quickly by placing it in a bowl set over another bowl filled with ice water. This method allows less time for bacteria to grow.
2. Once cool, quickly transfer the food to moisture- and vapor-proof freezer containers. Use small containers to allow food to freeze quickly, which slows bacteria growth. Remember, soups and other liquids or semi-liquids expand when they freeze, so leave about 1/2 inch space below the rim.
3. Thaw frozen foods in the refrigerator or in the microwave, never at room temperature.
