How Long Do Mushrooms Last in the Fridge?

Mushrooms are a tasty and incredibly nourishing addition to any meal. However, once you bring them home from the grocery store, they also don’t remain fresh for very long. Even worse, mushrooms frequently lack a sell-by or best-before date because they generate themselves. Therefore, you must determine whether they are fresh when buying and decide if they are still new enough to utilize at home.


Generally, fresh mushrooms can be stored in the refrigerator for approximately a week. The entire period could range from four to 10 days, depending on the variety. Your mushrooms’ shelf life will be increased by three to five days once you’ve cooked them.

What are Mushrooms?

Some fungi develop the reproductive structure known as a mushroom. It resembles the fruit of a plant, except that the “seeds” it produces are millions of microscopic spores that grow in the gills or pores beneath the cap of the mushroom. The spores are dispersed by the wind or in other ways, such as animal feeding. If spores drop on a suitable substrate (such as wood or soil), they will germinate into a network of microscopic rooting threads (mycelium) that enter their new food source. Mycelium endures for many years, collecting nutrients and producing an annual crop of mushrooms, in contrast to the mushroom, which appears and disappears fast.

Because of their high water content, spongy texture, and mild flavour, mushrooms are very adaptable in the kitchen. Mushrooms have high water content; therefore, storing them in the refrigerator for more than a few days may result in sliminess or even the growth of mildew and dark stains. Fortunately, there are several methods for maximizing the shelf life of mushrooms in your refrigerator.

How Long do Mushrooms Last in the Fridge?

Avoid stacking other containers on the mushrooms to prevent bruising and quick deterioration. Try making space in your refrigerator to enable appropriate excellent air circulation.

  • They are letting mushrooms in the refrigerator can extend their shelf life, like many other foods.
  • This may also have a significant impact. You can only count on your mushrooms to stay fresh for one to three days if they are just left out on the counter. However, if they are chilled in the refrigerator, they might only last a week or so.
  • There is no rivalry. Put those mushrooms in the refrigerator, and you could eat them for almost two weeks.

Types of Mushroom

All kinds of mushrooms, including shiitake, Portobello, and cremini varieties, have a limited shelf life that varies depending on how it is handled. The shelf life of mushrooms varies depending on how they are cooked.

1. Entire Mushrooms

The majority of whole mushrooms from the grocery store can be stored for up to two weeks in the refrigerator. After purchasing them, I was eating them within seven to ten days is best.

2. Sliced Mushrooms

Pre-sliced mushrooms from the grocery store should be used within a week, but specific batches can expire in just five days.

3. Cooked Mushrooms

Sautéed mushrooms can be kept in the fridge for seven to ten days and have a longer shelf life than sliced raw mushrooms. It’s also crucial to remember that mushrooms can spoil earlier if used in a recipe with other ingredients that break quickly.

4. Marinated Mushrooms

Marinated mushrooms have been dipped in olive oil, typically along with other ingredients like lemon juice and spices, and then sealed in a glass jar to be kept in the fridge. The majority of marinated mushrooms can keep for ten to fourteen days.

5. Dried Mushrooms

If properly stored, dried mushrooms can survive up to three years. They can be kept at room temperature on the counter or in the pantry instead of in the refrigerator.

6. Frozen Mushrooms

Although fresh mushrooms can be frozen, many lose their structure and are mushy when thawed. Cook, blanch, sauté, poach, or steam your mushrooms before freezing them to help preserve their flavour and texture. Then, freeze each one until it is excellent for a few hours on a baking sheet coated with parchment paper. To avoid freezer burn, store the frozen, loose mushrooms in an airtight, vacuum-sealed plastic bag.

How to Keep Mushrooms Safe?

Depending on how you cook them, mushrooms can be stored in several ways. Check your mushrooms for symptoms of spoilage such as dark stains, slime, stink, or crease before you prepare them. Any rotten mushrooms should be thrown away. Mushrooms can be easily kept in their original packing, but a different container can help them last longer. Here is a brief explanation of how to preserve mushrooms to save them from spoiling quickly.

1. Do Not Wash or Dry Your Mushrooms

Before storage, washing or soaking your mushrooms can make them absorb too much water, hastening their expiration. To remove any remaining dirt or grime, use a moist paper towel to wipe off the mushrooms.

2. Get Your Mushrooms Ready

The time your mushrooms can last will depend on whether you store them whole or in bits. If you wish to freeze your mushrooms, you can also choose to blanch or sauté them.

3. Select the Container

Pick the ideal method of mushroom storage. As fungus frequently flourishes in wet, sealed conditions, fresh mushrooms should be stored in a porous container to encourage air circulation and with paper towels to absorb any excess moisture. Your raw mushrooms can be reserved by loosely wrapping them in a paper towel before placing them in an exposed plastic or brown paper bag. Like any other prepared food, cooked mushrooms should be in an airtight container.

6 Ways to Identify Bad Mushrooms

The ability to distinguish between good and bad mushrooms is not as challenging. The traditional warning indications are as follows:

1. Slime

The first thing to look for is a slimy film covering the mushroom. Your fungi will develop this slimy covering if you store them in the refrigerator or at room temperature for longer than the recommended two weeks. The mushrooms may not yet be spoiled, but they will undoubtedly no longer be fresh.

2. Dim Areas

Overly extended storage of mushrooms in the refrigerator will result in surface bruising. It would help if you used them before they go wrong since they can still be good to eat.

3. Fine lines

When a mushroom is getting close to the end of its shelf life, its water content can decrease and wrinkle. This frequently occurs when fungi are exposed to room temperature and are allowed to dry naturally. If only they would have lost their meaty crunch, throwing away mushrooms that appear too dry is better.

4. Smell

A fishy, overtly aromatic odor will emanate from rotten mushrooms. Typically, a slimy layer and spots appear on the fungi’s surface. You will be persuaded that you need to get rid of your collection of fungi just by the distinct odour.

5. Mold

Look for mold, especially on the mushroom’s underside. When incorrect storage is combined with the high water content of mushrooms, mold can flourish. Even if only a few mushrooms have mold, you should discard the entire bag.

6. Date of Purchase

Usually, all it takes to determine whether mushrooms are wrong is a glance, touch, or sniff. How long they’ve been in the refrigerator is the last test. As a general rule, discard any mushrooms stored in the fridge for longer than two weeks, especially if there are other indications of deterioration.

5 Methods for Storing Mushrooms

If mushrooms are not handled carefully or stored correctly, they will quickly go rotten. Here are some pointers to help you keep your mushrooms properly:

1. Select the Proper Storage Container

Because fresh mushrooms contain a lot of water, you should be cautious about the type of container you use to preserve them. Though popular alternatives for packing food for refrigeration, airtight containers and plastic bags are not the most excellent options for keeping mushrooms. The mushrooms’ shelf life is shortened by this type of packing, which traps a film of moisture on their surface.

The ideal container for storing fresh mushrooms is a brown bag. The bag will absorb the mushrooms’ moisture, keeping them from deteriorating too rapidly. Ensure not to stuff too many mushrooms inside and keep the bag open at the top. The fresh fungus should last for up to a week if kept in the fridge.

As an alternative, you can keep mushrooms in their original shop packaging. These are often made to allow for proper airflow while preventing excessive wetness.

2. Keep Your Items in the Right Place

Always keep fresh mushrooms in the refrigerator. However, it depends on where you keep them in the fridge. Instead of putting mushrooms in the crisper, which is excessively damp and would make them mushy and eventually rot, we advise putting them in the fridge’s main compartment.

3. Bulk Dry Mushrooms

Drying is a terrific technique to keep mushrooms fresher for longer if you have a lot of them on hand but not much freezer space. As savoury and nourishing as fresh mushrooms are dried ones.

The mushrooms should first be cleaned before being baked for 3-5 hours at 17 degrees or until there is no longer any water sign. Before storing them in an airtight container, let them cool. Store it in the pantry as soon as you are ready to use it.

4. Congeal

When drying is not an option, the next best thing is to freeze the product. Fresh mushrooms should be frozen as soon as possible since the longer they are left out, the more they will deteriorate, and freezing won’t stop this deterioration once it has started. In a moment, we’ll demonstrate how to freeze mushrooms properly.

 5. Adhere to Strict Hygiene Standards

Mushrooms can readily get infected and dangerous because they lack a peelable outer skin.

Experts concur that it’s better to store mushrooms unwashed. Therefore, wash and dry your hands before touching your mushrooms, especially if they are already damp.

Additionally, we advise keeping your mushrooms entire. The stalk should never be chopped, peeled, or removed as this results in bruising and significantly reduces the shelf life of the fungus.

Can You Freeze Mushrooms?

  • Even though you may have purchased that grocery pack of mushrooms, you already know you won’t be able to use them within the next 7 to 10 days. The good thing is that you can freeze them.
  • But there are some disadvantages as well. Because of their high water content, mushrooms sometimes appear melancholy after they defrost.
  • Mushrooms can be cooked in a pan before freezing or put in a container to hibernate. They can be stored in the freezer for nine to twelve months, but thaw them thoroughly before using.

What Occurs if You Consume Stale Mushrooms?

Eating moldy or damaged food can have the same effects as eating spoiled mushrooms.

You could be fortunate and avoid any problems or suffer from symptoms ranging from a stomach ache to becoming very ill with food poisoning.

Do Mushrooms Spoil in the Refrigerator?

Yes, mushrooms will continue to spoil in the refrigerator and won’t last indefinitely if stored there.

Even if you store them in the refrigerator, you should still try to use them within a week. Like any fruit or vegetable stored in the fridge, they are susceptible to spoilage.

Can One Rotten Mushroom Ruin the Entire Batch?

Remove any moldy mushrooms you spot in a container immediately to prevent them from spreading to the others.

The other mushrooms should be safe if they don’t exhibit mold symptoms, but they should be cooked within a day or two.

Any mold or germs should be destroyed by the intense heat used to cook them. But if you’re unsure, discarding the entire container is always safer.

Do Mushrooms Must They be Cut into Slices?

You can cook whole mushrooms, sliced into half, quarters, or both. Oyster and maitake mushrooms, which are more extensive, can be torn into bits. Learn more about the 20 most common types of mushrooms that you can prepare.

To prepare mushrooms, you don’t necessarily need to slice them; be creative!


Refrigeration is required for fresh mushrooms, and they shouldn’t be anticipated to stay longer than a day when left outside in a room with a temperature of the room. Before becoming bad, fresh mushrooms should be kept in the refrigerator for approximately a week. They will survive a little longer if you store them in a paper bag or make small holes in a plastic container to reduce excess humidity. Your mushrooms will remain fresher in the fridge for three days if you cook them. Here are 30 of the best mushroom recipe suggestions for you to try.

If you don’t think you’ll be able to use all of your mushrooms within a week, you can freeze, dehydrate, can, or pickle them to extend their shelf life. Fresh mushrooms are the most acceptable option for all of these.
