How to store miso soup?

To store miso soup in the refrigerator, transfer it to an airtight container and keep it in the fridge where it will remain fresh for 2 to 3 days. To get the best results, separate any ingredient, like, tofu, seaweed, and onion, from the soup and then store it. 

However, if you only want to store it overnight, you can keep the solid items in the soup. Keeping the solid ingredients in the soup for more than 24 hours will make it go bad rapidly as these items go bad immediately after 24 hours. Taking tofu out of miso soup ensures that it doesn’t become soggy.

Can you freeze miso soup?

Yes, you can freeze miso soup for a shorter duration compared to its paste form. When kept in an airtight container with a proper seal, it can be well kept in the freezer for up to 6 months. 

With time, the container you kept your miso soup in will most likely expand, resulting in a freezer burn layer over the miso soup. You can avoid this problem by storing it in a larger-sized container and sparing some headspace for the container to expand.

How to freeze miso soup?

Before freezing miso soup:

  • Wait for about an hour for it to cool down.
  • Once it is cooled, start freezing it. If you want to pre-freeze it to later use it as an ingredient in another dish, simply put the soup in ice cube trays and wait for it to be completely frozen.
  • Once they are frozen, take the miso soup cubes out of the ice cube tray and transfer them to a freezer-safe bag.

However, if you don’t want to pre-freeze the miso soup, transfer it directly into a freezer-safe bag. Squeeze as much air out as you can before freezing it.

Note: Make sure to not leave miso soup for 2 hours at room temperature for it to be cool enough for freezing. Leave it only for 1 hour at room temperature before freezing it. 

Is miso soup good after a day?

When refrigerated in an airtight container, it is safe to consume miso soup for 2-3 days.

Does miso go bad in the fridge?

Thanks to the high salt content of miso, it can be preserved well in the fridge without going bad. If properly sealed, miso can last for up to 2 years.

The best temperature to heat miso is 114°F. Temperature hotter than this will kill the probiotics.
