How Long Can You Freeze Mushrooms? 

You can freeze mushrooms for 9 to 12 months. But keep in mind that if you haven’t blanched or sauteed them beforehand, they can go brown or mushy in the freezer, although it is perfectly safe to eat them.

Even though you can freeze mushrooms for a long time, it is best advised to consume them sooner, rather than later, to make the most out of their flavor and quality. 

How to Store Frozen Mushrooms? 

You can store frozen mushrooms in any freezer-safe air-tight container or Ziploc bag. The key is to make sure that they are thoroughly covered from being exposed to air or freezer burns.

You can pour some olive oil into the container you are storing frozen mushrooms in, to help prevent freezer burns

The choice between Ziploc bags and containers comes down to how much freezer space you have.

If you are pressed for freezer space, Ziploc bags are your best bet as you can freeze them compactly and stack flattened bags of mushrooms over each other. 

How to Defrost Mushrooms? 

You could thaw the mushrooms by leaving them in the fridge for a couple of hours or overnight to thaw gradually.

But the best part of frozen mushrooms is that you can use them right out of the freezer in your recipes.

Keep in mind that the mushrooms can get soggy or mushy once they thaw. So, it is best to use them up in recipes that don’t call for thawing.

Once it defrosts, make sure to remove any excess water that collects, before using the mushrooms.

If you have sautéed the mushroom beforehand, you needn’t fry or bake it again. Simply heating it would be more than enough.

In fact, overcooking the mushrooms can make them lose their nutritional value.

Can You Refreeze Mushrooms? 

No, it is strongly advised not to refreeze the mushrooms. Once they thaw, the mushrooms change in their texture and quality.

Repeated freezing and thawing will only worsen this condition. So, it is best to consume them as soon as they thaw or right out of the freezer. 

If you wish to avoid having to refreeze or waste the mushrooms once they thaw, you can portion them before packing them into separate containers.

You could also flash freeze the individual pieces of mushrooms, which makes it easier to grab a handful without having to thaw a big batch. 

Do Mushrooms Freeze Well? 

Yes, mushrooms freeze well, but fresh mushrooms taste and add better flavor to your dish over frozen mushrooms any day.

But it is a great way to keep them stored for the long term. Mushrooms can last in the freezer for almost a year without losing their nutritional value

Blanched or sauteed mushrooms freeze better than raw mushrooms. The raw mushrooms turn brown over time in the freezer and are more prone to freezer burns.

FAQs

Can you freeze canned mushrooms? 

Yes, you can freeze canned mushrooms. But it is best to transfer them into a freezer-safe air-tight container or Ziploc bag before freezing, because the can may rupture in the freezer creating a mess and spoiling the mushrooms.

It is best not to freeze canned mushrooms for more than a couple of months.
