For our discussion, I’ll be talking about the cultivated mushrooms most people know as white button mushrooms or the brown crimini mushrooms. There are a ton of varieties of mushrooms and these general guidelines will be good for them, but they each have their own distinctive characteristcis.

Ingredients

Look for a clean smell. You shouldn’t be smelling something that is musty or moldy, but woodsy and fresh.
Look for firm flesh, not flakey (for general broad mushrooms as the varieties are many and textures can be different in a healthy mushroom), and not bruised or discolored
The gills (underside) should be closed and not black when you purchase them (they may as they continue growing even after harvest, so you want the freshest you can get when you purchase)

How to Freeze Mushrooms

You can freeze a variety of mushrooms in their raw state, but I don’t really like the end product as well as I like it when I do this variety. We save the fancier mushrooms for using fresh and raw or redhydrated for meals, but will freeze the button mushrooms a lot for inclusion into dishes like spaghetti sauces, stews, etc.

Clean Mushrooms

Rinse under water and allow to dry in the open air on a tea towel. YES, you can do it. Alton Brown proved it through an experiment on his show Good Eats that mushrooms only absorb a negligible amount of moisture in this process, which is so much faster than the next. The only issue is your dehydrated and frozen mushrooms will be a little browner as an end product, but it doesn’t affect their flavor at all.
Brush off with either a towel or mushroom brush.

Slice Mushrooms

You’ll need to slice your mushrooms in a uniform size if you can, and about 1/4″ will do.

I have played around with using an egg slicer to slice my mushrooms, but as you’ll see, because our mushrooms were just a tad less than perfectly firm, it killed my original egg slicer because I was a little too hard on the first slice.

So I had to go out and buy a new egg slicer to replace it.

There are some specific mushroom ‘slicers’ (but I’m not a big fan of unitaskers) out there, plus heavy-duty egg/mushroom slicers (this model has blades instead of wires which will work much better), or you could use an all-in-one gadget that does everything, If your mushrooms are super firm, this can work, and does save a lot of time. However, it’s best to go ahead and just get the knife out and make a party out of it!

Sautée Mushrooms

I get a fairly hot pan going and let those mushrooms carmelize a bit and then lower the heat a little and allow the mushrooms to cook. I use a little butter and oil mixture to help keep things from sticking, but you don’t want to use too much. Butter has a lot of moisture and you don’t want the ‘shrooms having to deal with that as well. Once the mushrooms have released their moisture, I tend to turn the pan up just a bit to help get rid of it.

You can also add a bit of salt to the pan once the mushrooms have turned this ‘transluscent’ color, as it will help facilitate the moisture reduction, but for freezing, I don’t do it.

Freeze Mushrooms

Lay your cooled mushrooms out on a tray, single layer and ‘flash freeze’ in the freezer

This is what they look like when they come out. The “frost” you see is not freezer burn, but the tiny layer of frost that they get when you first pull them out. You’ll want to act quickly to move on to the next step becuase they do begin to thaw fairly quicly on the surface, which will make them tend to stick together once you do the final storage.

Store Mushrooms

I store my mushrooms in 1C quantities in individual bags, then store in a larger bag. I remove all the excess air I can from each bag to help keep them from getting freezer burn. When I’m ready to use, I can just pull out a bag and toss the contents into a sauce.

It’s just that easy!
