So yes, you can freeze lion’s mane mushrooms but there are caveats you need to know first.
What you can’t do is freeze them raw. The mushrooms are too delicate and are likely to end up a mushy mess. You don’t need to worry, there is a way around this issue. You can blanch the mushrooms before freezing and this gives them a much greater chance of surviving the freezing process.
Blanching is a method of par-cooking the mushrooms without cooking them too much and it really helps when trying to freeze some veggies and fungi like mushrooms.
How To Freeze Lion’s Mane Mushrooms
The process for freezing lion’s mane mushrooms isn’t complicated but it does require a little bit of time. You’ll need to spend time blanching, flash freezing and refreezing to have success when it comes to freezing them:
- Clean
Wash your mushrooms to get rid of any dirt and debris. Allow them to drain while you prepare everything you need for blanching. - Blanch
To blanch the mushrooms you need a large cooking pot filled with boiling water, a colander and some prepared ice water. The ice water can either be a bowl of water that has been in the fridge to cool or you can pop some ice cubes into a bowl of water. Pop your mushrooms into the boiling water for 90 seconds, drain and then submerge in the ice water then drain again. - Dry
Allow the lion’s mane mushrooms to dry. Once the mushrooms have drained and dried then you can move onto the freezing part! - Flash Freeze
For best results, you need to do a couple of extra steps to ensure that the mushrooms don’t stick together too much in the freezer bag. Pop some parchment paper onto a baking sheet and lay out the lion’s mane mushrooms onto the sheet so that they are not touching. Put the tray into the freezer for about an hour until the mushrooms are frozen. - Portion
Once you are confident the mushrooms have frozen then you can take them out of the freezer and transfer from the baking sheet into a freezer bag. - Seal
Squeeze out any excess air to avoid getting that freezer burn taste and seal the bag tightly. - Final Freeze
Label the bag with the date and the contents and pop it back into the freezer.
3 Tips for Freezing Lion’s Mane Mushrooms
Now you know how to freeze them, we’ve got our 3 top tips which we strongly recommend following when freezing lion’s mane mushrooms to have the best results:

How Do You Defrost Lion’s Mane Mushrooms?
For best results, when using your frozen lion’s mane mushrooms you may not want to defrost them at all! If you are sauteeing or adding the mushrooms to a recipe you can pop them in while they are still frozen.
If you do need to thaw out the mushrooms instead then you can by popping them into a bowl and defrosting in the fridge for a few hours.
Can You Refreeze Lion’s Mane Mushrooms?
We wouldn’t recommend that you refreeze lion’s mane mushrooms. Once you have thawed them out you are likely to find that they are a little changed in texture and are softer than they would have been fresh.
If you attempted to freeze again then it is unlikely the mushrooms would survive the process and still be edible. On top of this, you are allowing bacteria to grow which could make you sick.
Do Lion’s Mane Mushrooms Freeze Well?
As we mentioned earlier in this article, mushrooms can be a bit difficult when it comes to freezing. They are delicate structures and have high water content. This makes the mushrooms softer in texture and can even be mushy at times once they have been frozen.
All of this adds up to a food that doesn’t freeze well and you are unlikely to find your frozen mushrooms are the same as they would have been if they were fresh.
They still retain their flavour so once you have added them to a recipe you shouldn’t notice a difference.
