Freezing Miso Soup

Depending on how soon you wish to eat your leftover miso soup, you may not want to immediately put it in the freezer. You may also want to consider not freezing your miso soup if you are only saving a small portion of the soup.

When kept in the refrigerator, miso soup can stay fresh for approximately three days before it should be thrown away.

How to Freeze Miso Soup

Before putting your miso soup in the freezer, you want to let the soup cool to room temperature. The best way to do this is to leave the soup out on the counter for approximately one hour; you want to keep track of how long you keep the soup out, however, since miso soup can only sit out for two hours before it starts to spoil.

Once the soup has cooled, you can then begin preparing it for storage in the freezer. The best way to go about freezing miso soup is to use an ice cube tray. You can pour the soup into the tray and place the tray in the freezer. Once the cubes have frozen, you can take them and place them in an airtight container that is freezer safe or a freezer bag.

Once you have transferred the soup to a container or freezer bag, you want to put the date on the bag. This can be used in order to determine if the soup is still good when you plan on using the miso soup or eating it.
