How to Freeze Mushrooms

There is only one approach to take when it comes to freezing mushrooms outlined below. This method will work for any mushroom variety if you wish to freeze them raw.

We would avoid using expensive, exotic or wild mushrooms for freezing though:

  1. Clean and Discard
    Clean your raw mushrooms with a brush to remove any visible dirt. Now is also the time to discard any which aren’t perfect. Freezing mushrooms won’t improve their texture or hide blemishes so discard any mushrooms which aren’t near-perfect now.
  2. Slice, Dice or Skip
    You now need to prepare your mushrooms. We would recommend doing the least number of cuts possible. If you can leave them whole, that’s perfect but you can also freeze sliced mushrooms.
  3. Portion into Bags
    Place your mushrooms into a freezer-safe bag and seal it up. As you get to the end of sealing it, squeeze out as much air as you can from the freezer bag.
  4. Freeze
    Place the bag in the freezer. After 30 minutes, you can give the bag a gentle shake to stop them clumping before returning to the freeze. This is to avoid having to flash freeze them.

If you’d prefer to store them when not raw then we’d recommend steaming them. Simply bring a pot of water to the boil adding a few squeezes of lemon juice. Add a steamer basket over the water and steam your mushrooms for a few minutes.

This can help to slow down any textural and nutritional breakdown which occurs in the freezer. It also, obviously, involves a little more effort.

If freezing mushrooms that are cooked then you’ll need to make sure you freeze them as soon as they reach room temperature. Do not leave them sitting out at room temperature for extended periods of time, however.

Can You Freeze Cooked Mushrooms?

Yes, it’s possible to freeze cooked mushrooms. Once cooked, allow your mushrooms to cool before portioning them into freezer bags, sealing them up and then storing them in the freezer.

5 Tips for Freezing Mushrooms

Now you know how to freeze mushrooms in a variety of ways, we’ve got our 5 top tips which we strongly recommend following when freezing them to have the best results:

Clean Thoroughly
You do not want to freeze dirt stuck to your mushrooms. Mushrooms will always find a way of secreting dirt so do want you can to ensure you brush away as much of the dirt as possible. You can also give wash mushrooms beforehand but ensure you dry them thoroughly with a paper towel.

Steam Before Freezing
If you have time, steaming the mushrooms for a brief few minutes before freezing can help retain some texture, which will inevitably be lost during the freezing process. This is much like blanching for other vegetables.

Make Dishes Beforehand
To avoid mushy mushrooms, making a dish in advance which can then be frozen is a great way to mask the textural changes. You could even throw the mushrooms into pasta sauces or pie fillings to use them up before freezing.

Use Expensive Mushrooms Fresh
Mushrooms do not freeze particularly well so avoid freezing expensive, exotic or foraged mushrooms such as morels as freezing them will ruin them.

Avoid Creamy Dishes
A rule that should be followed in all cases, avoid cream when freezing mushrooms. Cream will split in the freezer, leaving you with a grainy texture.

How Long Can You Freeze Mushrooms?

We wouldn’t recommend leaving your mushrooms in the freezer for much longer than 4 months. The longer you leave them in the freezer, the greater the chance they will become mushy then thawed out.

There is also a chance that some of the mushrooms’ nutritional benefits will degrade if left in for longer.

As always, make sure you label your mushrooms with the date on which they need to be used.

How Do You Defrost Mushrooms?

To defrost mushrooms, the best approach is to leave them in the fridge to thaw slowly. This will help to prevent some of the issues with their texture.

Once defrosted, drain off the excess liquid. You’ll then want to warm them through in a little oil or butter in a shallow frying pan over a high heat until fully cooked.

The same applies to defrosting mushroom soup or mushroom gravy. Make sure you place the bag in a bowl to avoid any mess in your fridge.

Can You Refreeze Mushrooms?

Mushrooms will already be impacted negatively when frozen once. Refreezing them would lead to a disaster.

M will become completely bland and mushy. Refreezing is not something that’s advised in any circumstances when it comes to mushrooms.

Do Mushrooms Freeze Well?

Not really… Frozen mushrooms can be used in soups, stews, casseroles and sauces. But we would avoid eating them as the main element of a dish (such as on toast).

Because mushrooms have a high water content, they can become quite mushy when they are frozen and then thawed.

This works fine when you’re cooking them in a sauce until they fall apart as the texture won’t impact you.

But if you were planning on storing your mushrooms in the freezer and then eating them as the main element of a dish then perhaps it’s time to think again?

If you’ve still got questions about freezing mushrooms or mushrooms in general, then these may help:

Can You Freeze Wild or Exotic Mushrooms?

You can freeze any type of mushrooms but, as mentioned, you will only want to use your frozen mushrooms in a sauce or stew. This does seem a waste for good-quality exotic mushrooms so if you can use them when fresh we’d recommend it.

Can You Freeze Mushrooms in a Cream Sauce?

We would advise against it. Any sauces containing cream can split, curdle and become grainy. Instead, try making and freezing a mushroom puree which you can then loosen with stock and cream to create your creamy mushroom sauce.
