How to Keep Mushrooms Fresh and Eatable

So you have bought or picked some fresh mushrooms and now you’re thinking about how much time they can spend chilled you may ask if you put them into. Or is it better to leave them on the countertop?

  • First of all, don’t leave the mushrooms at a too warm temperature or in the surrounding with too high moisture. They can easily get dry in the first case and rotten in the latter. Crisper drawer won’t work for the same reasons. For refrigerating, use either their native package or put the mushrooms in a paper perforated bag. Keep them away from any strong-smelling food in the fridge as mushrooms pick the external odors easily
  • For freezing, wash and brush them to delete any dirt and then slice and saute. Only when cooked mushrooms can be frozen! After they cool down, put mushrooms in a plastic bag and toss them to the freezer.

If we are talking about the marinated mushrooms bought from a store, simply follow the storage instructions indicated in the jar label and remember that these veggies can’t be consumed after their expiry date has passed!

Signs of Spoiled / Rotten Mushrooms

Everyone knows that eating spoiled or rotten mushrooms is dangerous since they can make you very sick. If the mushrooms you eat are store-bought, the risk of food poisoning is very low, and they pose even less risk if you eat them cooked. But if you like using mushrooms (especially fresh ones) in your dishes at home, you should be aware of the signs of spoilage/rot to avoid severe food poisoning!

Luckily, it’s easy to tell the difference between fresh and bad mushrooms. Fresh mushrooms are dry and firm, with a smooth and pleasant earthy smell. But when mushrooms start decaying, they become softer and often mushy.

Also, they develop a sticky and slimy residue. Bad mushrooms can also be shriveled, moldy, and discolored. The smell will also be very unpleasant.

Mushroom Storage Secrets

No matter whether you prefer fresh or canned mushrooms, you should know how to store them correctly to extend their lifespan. And if it may be clear how to deal with pickled mushrooms, storing fresh ones often results in questions from people. Below, you can find a few helpful tips on this subject.

Shelf Life of Pickled Mushrooms

The best thing about pickled mushrooms is that they can be stored for quite a long period of time. Usually, it’s 45 days or longer if you store them properly. If you want to extend the shelf life of marinated mushrooms, reseal the jar and place it in the refrigerator. Also, ensure that the original brine covers the top of the remaining mushrooms!

Shelf Life of Fresh Mushrooms

If you want to enjoy fresh mushrooms, you need to store them correctly since they can decay pretty fast! First of all, keep in mind that fresh mushrooms can stay fresh for about a week if you keep them in the refrigerator. However, depending on the variety, the actual storage time might be from four days up to ten days. 

But if you decide to cook your mushrooms, it will extend their shelf life by another three to five days.

Speaking of fresh mushrooms, you should never leave them uncovered on the counter for a long period of time! If you leave them like that, mushrooms will start decaying much faster!

Shelf Life of Frozen Mushrooms

Finally, if your goal is to keep a batch of mushrooms consumable as long as possible, consider freezing them. Low temperatures work great for keeping foods fresh and useful without causing damage to their texture. 

If you freeze mushrooms, most of them will last in your freezer for 9–12 months.

However, if you choose to freeze as a storage method, note that frozen mushrooms are most suitable for dishes that will be cooked because their texture may change a bit after thawing.

This is why we recommend adding them to soups, casseroles, or stews, or as a pizza topping.

Most Common Mistakes When Buying, Cooking, And Keeping Mushrooms

Never buy mushrooms that are already packed in a container

Well, at least try not to buy them like this. Instead, search for those that are sold loose. First, it will allow you to buy as much as you need and not to pay for extra unnecessary content. And second, loose fungi cost less. Besides, you can quickly examine loose ones to skip dark spots and check them for freshness.

Choose the right container

If you choose a plastic packet as a container for the fungi, then throw it away right now. This package makes air inside too moist making the content turn slimy quickly.

For the same reason, never toss them to the crispy container at the bottom of the fridge. An airtight container will also not work since it prevents moisture from evaporating which leads to dark spots to appear.

Instead, keep them in a paper bag open since it absorbs the excess moisture and lets the air circulate, and you’ll forget about the slimy fungi.

Choose the right container

Put them away from smelly foods

Never place fungi together with:

  1. herbs,
  2. cheese,
  3. strong-smelling things since they are quick in intaking odors

Clean them properly

Darners absorb water like sponges that’s why rinsing is not the correct option for cleaning them. Besides, excess moisture will make the fungi slimy with those dark dots around.

So if the plan is to consume them raw, just brush off the dirt with a dry paper towel (you can dampen it if the fungi are very dusty or have soil on them).

For the recipes that ask for cooking them, rinse darners and tap dry with a paper napkin.

Fry correctly

Mushrooms need space when being cooked so don’t crowd the pan when frying them for your recipes if you don’t like eating soggy darners. Also, these veggies need enough fat to be properly cooked so use enough oil/butter, otherwise, they’ll turn dark and shrivel a lot (that’s the sign that the pan is too dry).

These hints point to the most common mistakes that can be done when working with recipes that need mushrooms or when keeping fungi. Keep those in mind and you’ll never do them again.

29 thoughts on “How Long Do Mushrooms Last In The Fridge?”

  1. Will cooking mushrooms kill bacteria? I often buy them on the farm market so I can’t be 100% sure that they’re cleaned properly and absolutely safe.

    • Frying or boiling will indeed kill bacteria, but it will hardly destroy all the possible contaminants that could be found on fungi. So what I suggest is to wash them in hot water prior to cooking as an additional preventive measure.

  2. I have never thought of it but is it better to buy whole or sliced mushrooms? Does it make any sense of cutting them before selling?

    • It makes sense if you’re going to cook them on the day of purchase since cut fungi don’t last long even in the fridge. On the contrary, whole mushrooms will stay edible for seven days or so which is way better if they will be prepared a bit later.

  3. Is it OK to eat mushrooms that have gone brown? I have some champignons left but some of them turned brownish.

    • I would not recommend doing that. When fungi start getting darker, it means that they are in the process of spoiling right now. Just toss them away.

  4. My question might seem weird but are slightly slimy mushrooms okay to eat? They don’t stink and they are not dark.

    • If they have normal color and smell, cook them right now to give them maybe one more day of life. Otherwise, discard them since this slimy film is the first sign of spoilage.

  5. How do you keep sliced mushrooms fresh longer? I tried to remove them to the lower shelf of the fridge and even into the crisper. They always spoil so fast! Thanks.

    • Try to tightly wrap them with the cling film or toss them into a resealable packet. Aluminum foil will work well, too.

  6. How long are sliced mushrooms good in the fridge? Those that I buy always go bad in two or three days.

    • That was the same with me until I started to re-pack them correctly. I always store sliced fungi tightly wrapped with the cling film or foil in the fridge. It helps to keep them fresh for up to a week!

  7. How can you tell if mushrooms have gone bad? I have a basket that is half-full and it’s been in my fridge for a bit too long. Are there any obvious signs?

    • Hi! If they’re really too old, you’ll see a slimy film on them that’s sticky to the touch. Also, bad mushrooms will be dark. Just discard them if you don’t want to have trouble with your stomach!

  8. I ate some cooked mushrooms yesterday but it seems to me that they were a bit expired, like not rotten or something, but just a bit old. And now I feel slightly nauseous. Can you get food poisoning from mushrooms?

    • I guess, you can. On the other hand, if you don’t feel extremely bad (and I guess, you don’t since you’re able to write) and you’re not hospitalized, those mushrooms were probably a bit stale.

  9. Can you get sick from eating old mushrooms? How bad can be the consequences?

    • Yeah, you can feel nauseous and maybe have stomach pain or even throw up if they were really bad. But unless you ate rotten or molded fungi and badly poisoned yourself, you should not expect any nasty aftermath, I guess.

  10. What do bad mushrooms smell like? How to spot them if the surface is still OK?

    • Bad fungi will have a recognizeable ammonia-like and pungent odor, however, I heard that some sorts can even smell fishy! I’d recommend discarding such foodstuff for your own sake.

    • Well, everything depends on how bad they were when you ate them. In the worst case, you will have food poisoning with all the symptoms and probably, some medical treatment might be needed. But if the mushrooms were at the beginning of their decay, you’ll most likely just have upset stomach.

  11. I bought a box of breaded mushrooms and I couldn’t fit them in freezer. How long will they last in fridge?? Thank you

  12. Hello! Could you please explain in detail how to store mushrooms in the fridge? How to pack them and how to prep for storage? Thanks.

    • Hi! There is a simple tip: mushrooms stay fresh longer if you take them out of their container. Wrap them in paper towels, place in open plastic bags or paper bags, and keep them in the fridge.

  13. How long do sliced mushrooms last in the fridge? I bought some fresh ones today for dinner, but there’s still some slices left. I think I’ll use them for breeakfast. But will they be ok in the morning?

    • Of course they will! Sliced mushrooms can easily last for a couple of days stored in the fridge if they are not washed yet. If you wash them, they might turn bad sooner.

    • It depends on whether you mean only cooked mushrooms or you mean a dish with mushrooms that also contains other ingredients. See, cooked mushrooms can last in the fridge for 7-10 days. However, if you have a dish that contains mushrooms and other ingredients that go bad quickly, mushrooms will expire sooner!
