You've just snagged some mushrooms on sale, but now you're wondering, "What's the best way to store mushrooms?" Maybe you've just picked wild mushrooms and want to preserve your harvest beyond today. Here are three very basic ways to preserve mushrooms: storage in oil, dehydration/freeze drying, and pressure canning. Also included is how to use preserved mushrooms in recipes!
Are Mushrooms Healthy?
Yes! Mushrooms are not only tasty, but also full of:
They are also anti-inflammatory!
And with so many types of mushrooms to choose from both in stores and in the wild, you're bound to find at least one type of mushroom that you really enjoy eating. So much so that you're curious to know how to preserve mushrooms for everyday use.
What can I do with too many mushrooms?
If you have too many mushrooms, you can always eat them three times a day until they are gone. Or you can gift them to friends.
However, if you want to save their deliciousness for later, it's best to preserve too many mushrooms! With three different methods outlined here, you're bound to find one that works for you.
Some methods require nothing more than a jar; others require special equipment. Whichever way you choose to preserve mushrooms, be sure to experiment with the finished product to find your favorite way to eat them!
Preserve mushrooms in 3 ways
We'll cover three easy ways to continuously preserve mushrooms so you never run out of them throughout the year. These methods are:
- Preserve in oil
- Dehydrate/freeze dry
- pressure canning
You might be wondering...
Can I Freeze Mushrooms?
Freezing most mushrooms is a simple process:
- Gently pat the mushrooms dry with a towel.
- Cut them as evenly as possible.
- Place them on a baking sheet lined with parchment paper.
- Freeze until firm and place in a freezer-safe container.
Some mushrooms keep better if they are blanched or steamed beforehand. Grow Your Pantry has an in-depth article onFreeze mushrooms. However, freezing mushrooms gives a finished product that can really only be used for cooking. Once frozen and thawed, mushrooms are rather bland.
Freezing is definitely NOT my favorite way to preserve mushrooms!
Preserve mushrooms in oil
For those of us who love the texture of fresh mushrooms, lightly pickling and pickling them in oil is a fantastic way to preserve them! When preserved this way, mushrooms can be added to pasta dishes, scrambled eggs, and served over flaky baked fish.
Properly preserving mushrooms in oil is very important to avoid foodborne illnesses! Mushrooms are a low-acid food and require some type of acidic preparation added to a can of oil to prevent spoilage.
Don't plan on simply slicing up mushrooms and putting them in a jar of olive oil - that's not how we keep mushrooms safe in oil!
Basic instructions for preserving mushrooms in oil
As I mentioned earlier, this method partially pickles the mushrooms in acid; in this case vinegar.
- Cut into even slices with 1 pound of clean mushrooms.
- Bring 2 cups of white vinegar, 2 tsp. Slightly boil sea salt, 6 peppercorns, 6 cloves of garlic and cook for 5-10 minutes to get a flavorful brine.
- Blanch the mushroom slices in the brine in small batches for 1 minute each. The small batches help you process the mushrooms quickly.
- Place the mushrooms in sterilized pint jars.
- Cover with a light oil like avocado or something heavier like olive oil.
- Make sure each mushroom is covered in oil to avoid spoilage.
- Put the lid on each jar and refrigerate for at least a week before using. This time helps the flavors penetrate the mushrooms.
- These will keep in the fridge for 2-3 months.
They most likely won't last that long as you'll find that you love eating these pickled oil mushrooms on almost everything from your morning toast to your evening pasta dish.
How to dehydrate mushrooms and/or freeze dried mushrooms
The process for dehydrating mushrooms is basically the same as for freeze drying; The only real difference is the machine you use!
To prepare mushrooms for dehydrating and freeze drying:
- Pat mushrooms clean/dry.
- Slice each evenly. The even slices are important when dehydrating and freeze drying, as you want the mushrooms to dry at the same rate.
- Place on the trays suitable for the device to be used. Lay each mushroom slice flat and don't stack them on top of each other to ensure even drying.
After drying, the mushrooms should be brittle and light. Freeze dried mushrooms are extremely light.
Reconstitute dried mushrooms
To use dried mushrooms, simply throw them into recipes like soups and casseroles. They usually reconstitute sufficiently in the liquids of a prescription.
However, you can also add some hot water to a cup of dried mushrooms to slowly rehydrate them. If you want to enjoy them on pizza, take this step.
One of the best things about drying mushrooms is that you can pulverize them! Mushroom powder can be added to sauces, soups, smoothies, and even chocolate and ice cream. The taste of mushrooms varies, of course, but many take on a sweet hue after drying—something like malt.
- Place fully dehydrated or freeze-dried mushrooms in a high speed blender.
- Constantly pulsing to produce powder.
FYI, a freeze-dried mushroom blends into a finer powder than a dehydrated one, but both powders are pleasant and useful.
Pressure canning for the preservation of mushrooms
It is possible to preserve mushrooms! The consistency of canned mushrooms is about the same as those you can preserve by lightly pickling and oiling.
You can use canned mushrooms in the same way as they are delicious on:
- Homemade pizza
- past dishes
- Baked Chicken Recipes
- nutritious soups
- diced in casseroles
Basically, you can put canned mushrooms in anything you want to taste delicious!
Is Home Pressure Canning Safe?
Yes, pressurized cans at home are safe! However, if you haven't done a lot of canning, you may be asking this question about pressure canning safety because you've heard horror stories about canned goods exploding. Worse, you've heard stories of improperly canned foods causing illness and even death!
If you're a nervous conservator, I have some advice for you. Even if you're an experienced conservator and just need new ideas, this advice will work for you.

Angi calls this a pantry and it really is! The beauty of canning is that you are essentially creating your own grocery store in your pantry. Today we start preserving mushrooms; tomorrow, who knows!
- 14 pounds. (6.4 kg) mushrooms (weight before cutting stems)
- 5 cups (1.2L) water
- 4 1/2 tsp. (27 g) non-iodized salt (optional)

- Optional variations per 1 pint (500ml) glass:
- 1/2 TL. Worcestersauce
- 1/8 tsp. ground black pepper

For better color add 1/16 teaspoon of ascorbic acid per 250ml jar and 1/8 teaspoon of ascorbic acid per 500ml jar. Add optional flavor variations if desired.
- Pour the boiling water into each glass, leaving 1 inch of air free. Remove the bubbles with a bubble removal tool and recheck the headspace. Add more boiling water to the glasses to maintain the correct headspace. Wipe the rims with a clean, damp cloth. Put the lids and straps on the jars and load them into the pressure vessel.
- Process jars according to manufacturer's instructions at 10 psi (69 kPa) for 45 minutes for half-pint (250 mL) and 1-pint (500 mL) jars, adjusting height if necessary ( see page 21 ofPressure canning for beginners and beyond).
- After processing, allow the canning container to naturally depressurize, then remove the jars and allow them to cool on the counter for at least 12 hours. Check the seal and store the jars for up to 1 year (see page 28).Pressure canning for beginners and beyond).
