Mushrooms are a versatile ingredient, but they can be a pain to store due to their high water content and sponge-like quality. Fresh mushrooms are best consumed within a week of purchase, as their quality decreases rapidly after that. Proper storage is crucial to prevent spoilage and maintain potency, especially for magic mushrooms. The shelf life of fresh mushrooms can be extended by storing them in a paper bag in the refrigerator, while cooked mushrooms last for about 3-4 days. Freezing and drying are also options to prolong their lifespan, but improper handling can negatively impact their texture and nutritional value.
| Characteristics | Values |
|---|---|
| Freshness | Mushrooms are best consumed within the first week of purchase. |
| Storage | Store fresh mushrooms in a paper bag in the refrigerator. Avoid using plastic bags as they trap moisture and cause spoilage. |
| Washing | Avoid washing mushrooms with water before storing. Use a dry paper towel or cloth to wipe off any dirt or grime. |
| Freezing | Freezing mushrooms will preserve taste but reduce nutritional value and texture. Wipe them with a paper towel, store in an airtight bag, and consume within a few months. |
| Drying | Dried mushrooms have a longer shelf life and can be stored in airtight containers or resealable plastic bags in a cool, dark place. |
| Expiration | Fresh mushrooms typically last 3-7 days in the refrigerator. Signs of expiration include a foul odour, slimy texture, discolouration, and the growth of dark spots or mould. |

What You'll Learn
Fresh mushrooms spoil faster than dried ones
Fresh mushrooms have a high water content, and they need air to survive and thrive before being cooked. They are best consumed within the first week of purchase. After that, their quality decreases. When stored in a refrigerator, they can last anywhere between three and seven days. However, they spoil faster if they are not stored properly.
Fresh mushrooms shouldn't be washed with water as they act like a sponge and can absorb water, leading to quicker spoilage. They should be wiped clean with a dry paper towel or cloth before storing. They should then be wrapped in paper towels and placed in a brown paper bag. The paper bag should be kept in the refrigerator, on a shelf and not in the crisper drawer. This is because the high humidity of the crisper drawer can cause mushrooms to spoil faster.
Storing fresh mushrooms in plastic bags should be avoided as they trap moisture, making the mushrooms spoil faster. Paper bags are preferred as they allow for airflow, preventing excess moisture from building up and causing slimy or mould.
Dried mushrooms, on the other hand, have a longer shelf life and are considered a pantry staple by many chefs and food industry professionals. They can be stored in an airtight container or resealable plastic bag in a dark, dry place.

Proper storage is key to preservation
Before refrigerating, wipe the mushrooms with a dry paper towel or cloth to remove any dirt. Then, wrap them in paper towels and place them in the paper bag. If you don't have a paper bag, you can store them in an unsealed plastic bag or glass bowl. However, avoid sealed containers and plastic bags as they trap moisture and cause rapid spoilage.
If you want to store dried mushrooms, use an airtight container or resealable plastic bag and keep them in a cool, dark, and dry place. Dried mushrooms have a longer shelf life than fresh mushrooms and are a great way to prolong their life. Freezing is also an option, but it may affect the texture and nutritional value of the mushrooms.
To freeze mushrooms, wipe them with a paper towel, cut them into pieces, and place them in an airtight bag. Avoid washing the mushrooms before freezing, as they can become mushy and poor in quality after thawing. Frozen mushrooms can be steamed or sautéed before being transferred to a freezer-safe container.

Mushrooms are best consumed within the first week
Mushrooms are a versatile ingredient, but they can be a pain to store due to their high water content and porous nature. They are best consumed within the first week of purchase, as their quality decreases rapidly after that. Here are some tips to ensure your mushrooms stay fresh for up to a week:
Firstly, when you get home, wipe the mushrooms clean with a dry paper towel or cloth. Avoid washing them with water, as this can cause them to deteriorate faster. Mushrooms are like sponges and will absorb the moisture, leading to a slimy texture and faster spoilage.
Secondly, for storage, it is recommended to wrap the cleaned mushrooms in a paper towel and place them in a paper bag. Plastic bags should be avoided as they trap moisture and prevent airflow, causing the mushrooms to spoil faster. The paper bag helps to absorb any excess moisture, and the paper towel creates a barrier that extends the mushrooms' freshness.
Additionally, it is best to store the mushrooms in the refrigerator, specifically on the shelves rather than in the crisper drawer. The high humidity in the crisper drawer can expedite spoilage. With proper storage, your mushrooms should last anywhere from three to seven days in the fridge, depending on the variety and whether they are whole or sliced.
If you want to prolong the life of your mushrooms beyond a week, you can try drying them or freezing them. Dried mushrooms are a great pantry staple and can be stored in an airtight container in a cool, dark place. Frozen mushrooms can be cooked in various ways, but they may lose some of their nutritional value and texture.

Freezing mushrooms impacts their nutritional value and texture
Fresh mushrooms are highly perishable and tend to lose quality immediately after being harvested. Their high moisture content, neutral pH, high respiration rate, high level of enzymatic activity, and the absence of a protective cuticle layer on the skin all contribute to their rapid degradation.
Freezing is an effective method to extend the shelf life of mushrooms and reduce food waste. However, freezing mushrooms can negatively impact their nutritional composition, texture, and flavour. While freezing does not affect the calorie, fibre, or mineral content of mushrooms, it can reduce the content of water-soluble vitamins like riboflavin, niacin, and folate. The process of freezing and thawing can also affect the texture of mushrooms, making them softer and mushier.
To minimize the impact of freezing on mushrooms, it is recommended to freeze them as fresh as possible. Before freezing, brush off any visible dirt, but avoid washing the mushrooms, as they have a high water content and can become mushy when cooked. Trim their stems and place them in a freezer-safe plastic bag, squeezing out as much air as possible before sealing and freezing. Frozen mushrooms are suitable for cooked dishes like soups, casseroles, stews, pizza toppings, pasta, rice, or quinoa.
Alternatively, freeze-drying mushrooms is a highly recommended dehydration technique that effectively preserves their texture, colour, flavour, and nutritional content. This method maintains the product's original characteristics and extends its shelf life. However, it is an expensive process due to the need for specialized equipment and extended processing times.

Sliminess, discolouration and a foul odour are signs of spoilage
Mushrooms are best consumed when fresh. They are 95% water, so they show signs of dehydration and spoilage more distinctly than other produce items. Proper storage is crucial to keeping mushrooms fresh and edible.
Fresh mushrooms spoil faster than dried ones. The best way to store fresh mushrooms is to wrap them in a paper towel and place them in a brown paper bag in the refrigerator. Paper allows for airflow, preventing excess moisture from building up and causing sliminess or mould. Plastic bags should be avoided as they trap moisture, causing mushrooms to spoil faster.
Sliminess, discolouration, and a foul odour are signs of spoilage. Sliminess occurs when mushrooms have been stored incorrectly or have been in the fridge for too long. It is a clear sign that the mushrooms are beginning to decompose. A thin layer of slime can lead to mould. If discolouration is accompanied by other signs of spoilage, the mushrooms should be discarded. A foul odour is another sign of spoilage. Bad mushrooms may contain bacteria that can cause food poisoning, botulism, nausea, vomiting, and other intestinal discomfort.
To avoid spoilage, mushrooms should be consumed within 3–5 days of purchase. Delicate varieties, like enoki, oyster, and maitake, may spoil more quickly. Sliced mushrooms have more surface area and can spoil twice as quickly as whole mushrooms, so they should be consumed within 2–7 days.
