Mushrooms are delicate and perishable, so proper storage is essential to maintain their freshness and flavor. Mushrooms are a healthful and versatile ingredient in addition to being a tasty addition to many culinary masterpieces. However, in order to properly enjoy their distinct flavors and health advantages, they must be handled and stored correctly. Inadequate storage might result in mushy, discolored, or damaged mushrooms, which not only waste money but also compromise the taste and texture of your dishes. In this detailed tutorial, we will look at the best methods for preserving mushrooms in order to increase their shelf life and maintain their freshness.

What are Mushrooms?

Mushrooms are a form of fungus, which are different organisms from plants and mammals. They are members of the kingdom Fungi and are distinguished by their distinct reproductive structures known as fruiting bodies. These fruiting bodies are the visible portion of the mushroom that we see above ground.

Mushrooms appear in a variety of shapes, sizes, and colors, and they play important ecological roles in nature. Some mushrooms are edible and are used in culinary recipes for their distinct flavors and textures. However, it is critical to use caution when eating wild mushrooms because some species are hazardous.

Mushrooms are intriguing organisms with several ecological, gastronomic, and medical applications.

How long do mushrooms last

Mushroom shelf life varies based on the type and how they are stored. Fresh mushrooms, in general, have a shorter shelf life than other vegetables. Here are some general recommendations for how long various species of mushrooms normally last:

Common Mushrooms (White, Cremini, Portobello):

If properly stored, these mushrooms can survive for around 1 to 2 weeks. To keep them fresh, keep them refrigerated in a paper bag or a loosely wrapped container.

Shiitake Mushrooms:

Shiitake mushrooms have a somewhat longer shelf life than regular mushrooms. They can be stored properly in a paper bag or a loosely closed container for up to 2 to 3 weeks.

Oyster Mushrooms:

Oyster mushrooms are more sensitive than other types and have a shorter shelf life. When properly stored in the refrigerator, they normally last 3 to 5 days.

Wild Mushrooms:

The shelf life of wild mushrooms varies. Some can be stored well for up to a week, while others may decay very quickly.

How to know if mushrooms are bad

The indicators of poor mushrooms vary based on the species of mushroom, but here are some frequent ones to look out for:

Discoloration: Fresh mushrooms should be uniform in color. If you see any dark patches, browning, or color changes that are distinct from their regular appearance, this could be an indication of spoiling.

Sliminess: The surface of fresh mushrooms should be smooth and dry. If they feel slimy or sticky to the touch, this is an indication that they are deteriorating.

Foul odor: Fresh mushrooms have a light, earthy scent. If you notice a strong, unpleasant odor, this could indicate that they have ruined.

Wrinkled or shriveled appearance: As mushrooms deteriorate, moisture is lost, causing them to wrinkle or shrivel.

Mold: Mold development is an unmistakable sign of deterioration. Examine the mushrooms thoroughly for any evidence of fuzzy mold, especially the undersides and crevices.

Excessive moisture in the packaging: If you see a buildup of water droplets or excess moisture inside the container, it may cause it to spoil faster.

Slimy stems: When certain varieties of mushrooms with stems become old, the stems can become extremely slimy.

Soft or mushy texture: Fresh mushrooms should be firm and somewhat crunchy. They are likely past their peak if they feel soft or mushy.

How To Store Mushrooms

1.Selecting the Best Mushrooms

Before we go into the storage methods, let’s speak about picking the correct mushrooms. Always choose fresh mushrooms that are firm, plump, and devoid of bruises or blemishes. If possible, choose mushrooms with closed caps to keep them fresher for longer.

2. Storing Fresh Mushrooms

Keep your mushrooms fresh by storing them correctly in the refrigerator. Here’s how to go about it:

2.1 Use a Paper Bag

Put your mushrooms in a paper bag to allow for sufficient air circulation and to prevent moisture buildup, which can contribute to early spoiling. Plastic bags should be avoided since they collect moisture and promote mold growth.

2.2 Refrigerate in the Right Section

Keep your mushrooms in the main compartment or vegetable crisper of your refrigerator, away from the freezer. The temperature in the main chamber is usually ideal for mushroom preservation, ranging between 34 and 38°F (1 and 3°C).

2.3 Avoid Washing Before Storage

Never wash your mushrooms before storing them since additional moisture may hasten their decomposition. Instead, clean them with a moist cloth or gentle brush just before using to eliminate any dirt or debris.

3. Extending Shelf Life with Preservation Methods

If you have an abundance of mushrooms and want to save them for later use, try the following methods:

3.1 Mushroom Freezing

Freezing mushrooms allows you to increase their shelf life by up to six months. Here’s how to go about it:

3.1.1 Cleaning and Blanching

Use a moist cloth or gentle brush to gently clean the mushrooms, then slice them to the appropriate thickness. Blanching them before freezing helps to preserve their quality. Blanch the mushrooms by immersing them in boiling water for 2-3 minutes, followed by a short plunge in ice-cold water.

3.1.2 Packaging for Freezing

Drain and store the blanched mushrooms in airtight containers or freezer bags. To avoid freezer burn, remove as much air as you can. To keep track of the freshness of the containers, mark them with the date.

3.2 Drying Mushrooms

Dried mushrooms offer flavor to a variety of meals and can be stored for an extended amount of time. Follow these instructions to dry your mushrooms:

3.2.1 Slicing and Dehydrating

To achieve even drying, slice the mushrooms evenly. To properly dry the mushrooms, use a food dehydrator or a low-temperature oven. The process could take many hours to finish.

3.2.2 Storage

Once dried, store the mushrooms in sealed bags in a cool, dry, and dark area. They can be preserved correctly for several months.

4. Mushroom Preserving in Oil or Vinegar

Preserving mushrooms in oil or vinegar not only improves their flavor but also increases their shelf life. Follow these actions to ensure safe storage:

4.1 Mushroom Preparation: Clean the mushrooms well and cut them into suitable sizes.

  • Preparing the Oil or Vinegar: Pick a high-quality vinegar like white wine or apple cider vinegar or an oil like extra virgin olive oil. Oil or vinegar should be heated until a moderate simmer is achieved.
  • Blanched Mushrooms: Before putting the mushrooms in the oil or vinegar, briefly blanch them to stop germs from growing. Drain and completely dry them after blanching.
  • Filling the Jars: Place blanched mushrooms in sterilized glass jars and cover with hot oil or vinegar, leaving some headspace.
  • Storing: Place the tightly closed jars in the fridge. While mushrooms preserved in vinegar can survive up to six months, those in oil should only last two to three months.

5.Avoiding Common Mistakes

Avoid the following mistakes to keep your mushrooms fresh and flavorful:

5.1 Leaving Them Uncovered

If you leave mushrooms out in the open, they will dry up quickly and lose their texture. Always keep them in their original packaging or wrapped in a wet paper towel.

5.2 Washing Mushrooms in Advance

As previously said, avoid washing mushrooms before storing them because excess moisture might cause deterioration.

5.3 Storing with Strong-Smelling Foods

Because mushrooms are porous, they can absorb scents from other strong-smelling items in the fridge. Keep them separate or in sealed containers to avoid taste cross-contamination.


Maintaining mushrooms’ freshness, flavor, and nutritional value requires careful storage. Every technique, including chilling, freezing, drying, and preserving them in vinegar or oil, offers benefits. By adhering to these recommendations, you can make sure that your mushrooms stay at their peak condition and are prepared to take your gourmet creations to new heights. So use these preservation methods the next time you harvest or bring home a batch of mushrooms and watch your kitchen flourish with their earthy richness. Have fun cooking!
