Mushrooms are a versatile ingredient used in cooking, especially in Asian and European cuisines. They have a high water content and a porous texture, which means they can act like a sponge, absorbing water and flavours. This makes them great to cook with, but also means they can be challenging to store. So, are mushrooms best kept in the fridge?
| Characteristics | Values |
|---|---|
| Shelf life in the fridge | 3-7 days for raw mushrooms, 3-4 days for cooked mushrooms, 7-10 days for sautéed mushrooms, up to 2 weeks for whole mushrooms |
| Storage container | Paper bag, porous container with paper towels, airtight container for cooked mushrooms |
| Freezing | Can be frozen but may lose structure and become mushy; cook, blanch, sauté, poach, or steam before freezing to preserve texture and flavor |
| Drying | Can be dried using a dehydrator or air-drying; store in an airtight glass jar |
| Marination | Can be marinated in olive oil, lemon juice, and spices, then sealed in a glass jar |
| Washing | Avoid washing before storing to extend shelf life |

Fresh mushrooms should be stored in a porous container with paper towels to absorb excess moisture
Fresh mushrooms have a short shelf life, and can quickly become slimy or develop dark spots and mould. To extend their freshness, it is important to store them correctly.
Mushrooms have a high water content, and their spongy texture means they soak up water like a sponge. Therefore, it is important to keep them dry to stay firm and fresh. The goal of mushroom storage is to prevent them from releasing water and pulling moisture from the air.
It is also important to note that mushrooms should not be washed before storing, as this can shorten their shelf life. Instead, they can be wiped with a damp cloth to remove any dirt.

Raw mushrooms can be stored in the fridge for 3-7 days
Fresh mushrooms are a versatile ingredient in the kitchen, but they can be difficult to store due to their high water content and porous texture. They can quickly become slimy and spoil, so it's important to store them correctly.
If you want to keep raw mushrooms for longer than a week, freezing is an option. However, this can affect their texture, making them mushy when thawed. To preserve their quality, it's best to cook them before freezing. Sautéing or steaming are good options, as they lock in the mushrooms' texture and flavour. You can also dry mushrooms, which can last for up to three years when stored properly.
It's important to check for signs of spoilage before consuming raw mushrooms. If they have dark spots, a slimy texture, or a pungent odour, they should be discarded.

Cooked mushrooms can be stored in the fridge for 3-4 days
Mushrooms are a versatile ingredient in the kitchen, but they can be a challenge to store. Their high water content and porous texture mean they can easily become slimy or develop dark spots and mould. To prevent this, it's important to keep mushrooms dry and store them in the fridge.
When it comes to cooked mushrooms, they can be stored in the fridge for 3-4 days. However, it's worth noting that they may develop bacteria that affects their taste and smell. To prevent this, cooked mushrooms should be stored in an airtight container, just like any other cooked food.
If you're looking to store cooked mushrooms for a longer period, freezing is an option. Freezing mushrooms can affect their texture, so it's recommended to cook them before freezing to help lock in their flavour and structure. You can sauté, blanch, poach, or steam them, and then freeze them on a parchment paper-lined baking sheet until they are frozen solid. Once frozen, transfer the mushrooms to an airtight, vacuum-sealed plastic bag to prevent freezer burn. With this method, cooked mushrooms can be stored in the freezer for up to 12 months.
Another option for long-term storage is drying your cooked mushrooms. This method involves air-drying or using a dehydrator and then storing the dried mushrooms in an airtight glass jar. Dried mushrooms have an intense umami flavour and can be reconstituted in soups, stews, sauces, or stir-fries. With proper storage, dried mushrooms can last for up to three years.
In summary, cooked mushrooms can be stored in the fridge for 3-4 days, but for longer storage, freezing or drying are effective methods that can extend their shelf life significantly.

Mushrooms can be frozen but should be cooked first to preserve their texture
Mushrooms have a high water content, and their spongy texture and mild flavour make them a versatile ingredient in the kitchen. However, their high water content means that keeping mushrooms in the fridge for longer than a few days can cause them to become slimy or develop dark spots and mould.
Freezing mushrooms is a great way to prolong their shelf life and reduce food waste. However, freezing changes the structure and texture of mushrooms, and they won't be pleasant to eat raw after being frozen. Mushrooms are like tiny sponges and absorb a lot of water, so freezing them raw can result in a soggy, mushy mess.
To preserve their texture, it is recommended to cook mushrooms before freezing. Lightly sautéing them in butter or steaming them whole will help lock in their texture and flavour. For the best colour post-freezing, you can dip mushrooms in a solution of water and lemon juice before cooking. Once the cooked mushrooms are cooled, place them on a parchment paper-lined baking sheet and freeze until solid. Then, transfer the mushrooms to an airtight, freezer-safe bag and store in the freezer for up to 12 months.
Dried mushrooms are another option for long-term preservation. They can be stored at room temperature and have an intense umami flavour, reconstituting beautifully in soups, stews, sauces, or stir-fries.

Dried mushrooms can be stored at room temperature and will last for up to three years
Fresh mushrooms are highly perishable and have a short shelf life. They are made of 80 to 90 percent water, which means they must be kept dry to stay firm and fresh. The refrigerator is the ideal location for storing fresh mushrooms, but they can last for a couple of days and then start to go slimy.
Dried mushrooms, on the other hand, can be stored at room temperature and will last for up to three years. They have an intense umami flavour and reconstitute beautifully in soups, stews, sauces, or stir-fries. To dry mushrooms, you can use a dehydrator or air-drying techniques. Place the mushrooms in a mesh container with good airflow for about a week. Once completely dry, store them in an airtight glass jar.
Even when stored properly, mushrooms won't last forever. They will eventually spoil and become slimy, wrinkled, soggy, spongy, and darker than their original colour. They may also develop an odour and mould. However, if your mushrooms only have a few dark spots, they are still safe to eat.
The best method for storing fresh mushrooms is one that keeps them free of slime and mould while enhancing their flavour. Fresh mushrooms should be stored in a porous container to promote air circulation, with paper towels to absorb excess moisture. You can also wrap the raw mushrooms loosely in a paper towel and then store them in an open plastic or brown paper bag.
