Miso is a paste made from fermented soybeans. Miso paste has a salty, savory flavor and is used in many different types of dishes throughout Asia. Most people know that miso soup is an important part of Japanese cuisine, but it’s also commonly found in Korean and Chinese cooking too. People often ask “How long does miso paste last?” or “Does miso go bad?” We will answer these questions for you today!
Why is miso paste so popular?
Miso can be used as an ingredient in many types of dishes, and it’s very popular in Japanese cuisine where the soup called misoshiru features large quantities of this salty paste.
You can prepare miso soup with tofu, wakame seaweed, or any other vegetables you like. Miso can also be used as a marinade for meat and seafood, to make dressings for salads and grain dishes such as rice porridge (okayu).
You may have heard that miso is fermented soybeans but it’s worth repeating because the process of fermentation has some interesting effects on its nutritional value.
Does miso go bad?
Miso is not perishable and does not go bad if stored properly in the pantry or refrigerator. Sure, once open it will only last for a few months in the fridge, but if the package is closed and stored properly then it will last indefinitely. Some people have reported eating miso after 5-10 years of being in the pantry!
However, the texture of miso paste will change as time goes by. It may become drier and more crumbly, or it might turn into a thick liquid. It’s still safe to eat but the flavor might be muted or have a funky smell.
How long does miso paste last?
Once open, miso can stay fresh for up to 3 months when refrigerated, but it’s better to use them within a year or so of purchase because they start tasting sourer after that time. Definitely check the expiration date when you buy it if you want to be on the safe side.
How to properly store miso?
If you’re using it within the next three months, store miso paste in your refrigerator. If not refrigerated, then a closed package of miso paste will last indefinitely on your pantry shelf.
How to tell if miso paste is bad?
Miso has an almost indefinite shelf life and does not go bad as long as it’s stored properly. You might want to use it before the expiration date though.
Miso is a paste made from fermented soybeans that have been used in Japanese cuisine for centuries, but like any other food product, miso will eventually go bad if not stored properly or left out too long at room temperature (years).
