Does Mussels Freeze Well?

Mussels do freeze very well which makes them great for storing long term. You can either freeze them cooked or uncooked. Both will freeze and retain their freshness, but how long they’ll stay fresh will depend on other factors. Some of the factors are the freezer’s temperature and whether it’s freshwater or saltwater mussels.

As for the temperature, if the freezer is at a constant 0 degrees Fahrenheit, the mussels will last for a very long time. On the other hand, if the temperature fluctuates often, the mussels will not last very long. As the door of the freezer opens, warm air rush in and thaws the mussels a bit. If the door is left open for an extended period of time, it could actually damage the mussels.

Therefore, it’s important to keep the door of the freezer closed as much as possible.

Saltwater mussels tend to freeze better and last longer in the freezer than freshwater mussels. This is due to the salt content in the flesh of the mussels. The salt actually helps preserve the flavor and texture of the mussels.

Fresh mussels can be frozen and remain fresh for up to 6 months. After that, the mussels will still be safe to eat, but the quality will decrease. Like any other food, storing mussels in the freezer too long will cause them to get freezer burn. This will cause the taste and texture of the mussels to deteriorate.

Cooked mussels, on the other hand, will stay fresh for up to 3 months. Since the mussels are cooked, the flesh doesn’t contain much water. Water helps keeps the flavor intact and holds the texture of the mussels since water freezes really well.  Therefore, without liquid, cooked mussels won’t last the longer 3 months.

However, this doesn’t mean you can’t eat them. After 3 months, the quality will start to deteriorate so it won’t be as fresh as when you bought it.
