It is a well-known thing that mushrooms are one of the best alternatives to meat. Although it is a very well-known fact, only a few know how long do mushrooms last. As a food lover, I know you are not typing these kinds of stuff on Google unless you are on the verge of trying a new recipe.

How Long Do Mushrooms Last?

I am pretty much sure that you will definitely try many mushrooms recipes after this one. So, why don’t you get clarification about some frequently asked questions about mushrooms’ longevity, such as do mushrooms go bad, how long do mushrooms last after cooked or in the fridge, and so on.. I see myself as a problem-solver, so I have structured this article as a Q&A session. 

How Long Do Dried Mushrooms Last?

Great news! Dried mushrooms last for an indefinite time period if you store them properly. Properly in a sense, you must make sure you leave no space for air to creep inside the container and store it in a cool and dark place.

I don’t know about you people, but I always tend to end up with excess and unused mushrooms whenever I bring them down. So, my next drying them up is the next best possible option I have, and you have to believe in this, dried mushrooms are as awesome as fresh ones; I hate them throwing mushrooms in the trash.

How Long Do Mushrooms Last After Harvest?

This may be out of my scope, but experts say that one must put the freshly harvested mushrooms in a fridge as soon as possible. If you refrigerate, mushrooms have the capability to last up to one week under normal circumstances.

This veggie has high water content in it, and once you pick it, it would be very difficult for the mushrooms to retain the water for a long time if you don’t store them in a fridge. I usually cook the mushrooms right after I purchase them because, in order to relish the authentic taste of mushrooms, you must cook them right after the harvest.

How Long Do Mushrooms Last After Opening?

When I open up a jar of mushrooms, I make sure to consume them all within four to seven days. The canned mushrooms last longer compared to other versions until the cans get opened. Also, you can read all the information, including best-by-date, on the labels.

After you open the can, you must finish it before a week. However, my expertise confirms that there is a slight change in taste when you reach the last couple of days of the week. I would say it is better to plan them using inside first four days. I think you don’t want to eat bad mushrooms, right?

How Long Do Mushrooms Last At Room Temperature?

Those who think how long you can leave raw mushrooms out at room temperature, please look away. They last only for around 12 hours in most situations. Some mushroom variants could last a maximum of a day but no more.

The room temperature is ideal for the bacteria growth, and mushrooms will become inedible if left unattended in such temperature levels within a matter of hours. My advice for the readers is to use mushrooms as soon as they are opened if you don’t have the facilities to store them in a cool and dark place. 

How Long Do Mushrooms Last After Washing?

My years of tests and mistakes suggest that they last no more than three days after been washed, given you store them in a fridge in a proper manner right after you open the packs or cans. However, I have come across certain types, such as Oyster mushrooms, that have the capability to last much longer.

In fact, the lifespan of washed Oyster mushrooms can get extended up to five or six days. So, consider the three-day window as a general rule. Remember what I said? You have to cook mushrooms as soon as possible to get the true taste. 

How Long Do Mushrooms Last Once Cooked?

The best part of cooked mushrooms is that they can last about ten days without much difference to the taste. However, storing process has to be done in a proper way. Usually, I use two methods to store cooked mushrooms in a fridge.

My go-to option is to put them in an airtight container as it provides me with the opportunity of getting them out easily when I want to use them. Else, I put mushrooms in a re-sealable plastic bag, especially when I have small amounts to store for future use.

Another important thing is you should always make necessary arrangements to store the cooked mushrooms within two hours after you cook as allowing more time under room temperature won’t help the preservation.

How Long Do Mushrooms Last In The Freezer?

Talking about how long do mushrooms last in a freezer, I have noticed they keep the outlook intact for about six months. However, Freddy, a good friend of mine, said the other day that his experiment with frozen mushrooms had not gone according to his plans.

The reason for this identified as frigid temperature levels. Yes, mushrooms tend to get freezer burned when kept in frigid temperature for too long. That said, there won’t be any issue up until six months if you make sure to provide proper conditions to mushrooms. 

How Long Do Mushrooms Last In A Jar?

Jarred mushrooms come with brine, which is a super important factor that decides the life span of the mushrooms. First of all, I look for strange odors and molds to verify the mushrooms are in good condition to eat. Once you opened the jar and you have more to preserve, it is mandatory to cover the top of the mushrooms with brine in order for them to last for long.

If you ensure that and place it in a fridge, you should be able to preserve mushrooms for about 45 days. Having said that, it is your duty to check for mold in the mushrooms as well as in the liquid before you use as it is easy to recognize spoilages in that way.

How Long Do Mushrooms Last In A Bag?

My advice is to store mushrooms in whole when you use plastic bags. This will help you prevent them go slimy quickly, and also, I keep them away from other food inside the fridge. When stored properly inside a fridge, mushrooms can last about one week in a bag without a problem.

However, for those who want to store peeled mushrooms for more than a week, my recommendation would be to use a freezer in place of a fridge.

How Long Do Mushrooms Last In Honey?

Honey is one of the natural products that don’t go bad quickly. This is because of the high sugar content, which makes it difficult for the bacteria to grow. Still, the mushrooms have water in them, and that water content can aid the growth of bacteria.

Although I have never tried this before, experts state that it is better to store dried mushrooms in honey rather than fresh ones. As per their words, raw mushrooms in honey won’t last more than ten days.

How to Tell If Mushrooms Are Bad?

Alright, I think you are now clear with how long do mushrooms last. The next question that arises is how to tell if mushrooms are bad. I want to cover every corner of this topic, so I thought it would help you if I explain my experience with bad mushrooms.

Before that,If you want to learn more about mushrooms and It’s alternatives, read the article on mushroom types and alternatives.

Slimy Texture

When I notice a slimy texture on the mushrooms, I throw them in the trash, which is the number one rule for bad mushrooms. Allowing mushrooms at room temperature is one of the main reasons why mushrooms get slimy.

Also, you can’t expect them to retain the freshness for too long in a fridge as well. I have seen people tossing up such mushrooms in order to get rid of the slimy texture, but personally, I don’t recommend that to my readers.

Wrinkles

The slimy texture might not be visible on certain sorts of mushrooms even after they go bad. That is why I advise you to check for the wrinkles on the mushrooms before you cook. However, you must know how to identify relatively dried mushrooms from wrinkles separately, as mushrooms do tend to get dried after they lose the water content in them. So if you notice too wrinkly mushrooms, do not get tempted to use them in your recipes.

Darker Spots

I always ensure to keep a close eye on mushrooms even when they are stored in the fridge. When I notice darker spots forming on the mushrooms, I know that they are starting to go bad. I have no issue if you consume mushrooms that are at the early stage of the dark spots formation. But, it’s something that you need to do with care as I don’t want you to comment below asking, “I ate slimy mushrooms, what should I do”?

Strong Odor

Usually, mushrooms don’t have a noticeable smell. However, if you come across any kind of a strong odor, that is an indication that mushrooms have gone bad. There is no rocket science in here as you could easily identify any strange smell once you stick your nose right up to them.

Over Ten Days

As I mentioned earlier, mushrooms’ shelf life when kept in a fridge is about a week. So, if you don’t use them for more than ten days, there would be a slim chance available for mushrooms to retain their freshness. However, you can use the above-mentioned visible spoilages along with your common sense to make sure they are still edible before throwing them out of the window.

How to Keep Mushrooms Fresh?

By now, you should know that keeping in a fridge or freezer is the easiest method you can use to preserve the mushrooms and retain them fresh. However, there is another way; that is to dry mushrooms for future use. I will explain all three methods a wee bit so that you can determine the method that fits you the most.

In A Fridge

First of all, I do not keep my mushrooms in the crisp drawer simply because this place has more moist compared to other compartments. In addition, ensure not to store mushrooms alongside foods that have a strong smell or flavor. Also, do not place any other food on the mushroom packages as bruised mushrooms don’t last for the time that they should be. 

Another crucial side is never to buy mushrooms if you are not planning to use them sooner because some sorts might not provide even the time periods that I explained thus far.

In addition, don’t peel the mushrooms before you store them in the fridge. The whole mushrooms can retain the water content way more efficiently than the peeled version. Finally, opt for a freezer if you want them to last more than ten days. 

In A Freezer

Mushrooms like to be in a freezer than a fridge as it helps them to be fresh for at least up to six months, given you have provided them with suitable conditions. However, if you want to use a freezer to make them last for months, my tip would be to don’t wait for mushrooms to deteriorate in the fridge and then transfer them to the freezer. Instead, try to place them in the freezer right after you bring them home. 

Drying Mushrooms

Drying mushrooms is the next best possible method for you to preserve them. Although it is not a method to use them freshly, there are tons of recipes you can try with dried mushrooms. Also, you have the chance to rehydrate them whenever you need them.

Drying mushrooms is not a difficult task; all you have to do is use a low-temperature oven or food hydrator. After you dry mushrooms, keep them in an airtight container until the using time arises.
