Mushrooms are versatile ingredients that add an earthy richness to dishes. However, they are delicate and perishable, so proper storage is essential to prevent slime and spoilage. The best way to store mushrooms is in the refrigerator, but which spot you choose impacts preservation. Here are some tips and tricks to keep your mushrooms fresh and slime-free.
| Characteristics | Values |
|---|---|
| Shelf life | Mushrooms last in the fridge between seven and 14 days. |
| Container | Mushrooms should be stored in a breathable container like a paper bag or cardboard drinks tray. |
| Plastic wrap | Plastic wrap should be avoided as it traps moisture, contributing to quicker spoilage. |
| Paper towels | Paper towels can be used to line the container to absorb moisture. |
| Crisper drawer | Mushrooms should not be stored in the crisper drawer as it is too moist. |
| Washing | Mushrooms should not be washed until directly before preparing, cooking, or eating. |

What You'll Learn
Use a paper bag
Mushrooms have a high water content, so they need to be stored in a cool, dry place like a fridge to keep them fresh for as long as possible. Storing mushrooms in a paper bag is a great way to regulate moisture and keep them fresh for up to 10 days.
Firstly, remove the mushrooms from any plastic packaging. Mushrooms are porous and sponge-like, so they can absorb odors from strong-smelling foods in the fridge. Leaving them in their original packaging can also trap moisture, contributing to quicker spoilage.
Next, place the mushrooms in a paper bag. Paper bags are breathable and allow for better airflow, creating a less damp environment for the mushrooms. The paper will absorb any moisture released by the mushrooms, keeping their surface slime-free for longer.
You can also line the paper bag with a paper towel to draw away even more moisture. Simply wrap the mushrooms in the paper towel and place them in the bag, leaving it open at the top.
Finally, place the bag on a shelf in the fridge, not in the crisper drawer, which tends to be a more humid environment. With this method, your mushrooms should stay fresh for up to 10 days!

Avoid the crisper drawer
The crisper drawer is designed to create a humid environment, which is great for leafy greens but not so much for mushrooms. Mushrooms have a high water content (80-90%) and are sponges to other moisture. The crisper drawer's moisture will only encourage the growth of bacteria, leading to the formation of slime and, eventually, mould.
Mushrooms kept in the crisper drawer are also more likely to be stored in their original packaging, which is usually a plastic container or plastic wrap. Plastic traps moisture, which contributes to quicker spoilage.
Instead, store mushrooms in a breathable paper bag, which allows for much better airflow and creates a less damp environment. Paper bags absorb the moisture that mushrooms naturally release, preventing them from getting slimy.
If you don't have a paper bag, you can use a paper towel-lined zip-top plastic bag. The paper towel will draw moisture away from the mushrooms, allowing them to last longer.

Don't wash mushrooms before storing
When storing mushrooms in the fridge, it is best not to wash them beforehand. Mushrooms are delicate and perishable, and moisture is the number one enemy when it comes to keeping them fresh. Washing mushrooms before storing them will shorten their shelf life, so it is best to keep them dry until you are ready to use them.
Mushrooms have a high water content, and when washed, they can quickly become slimy and spoil. This is because the additional moisture on the surface of the mushrooms can encourage the growth of bacteria and mould. Therefore, it is recommended to only wash mushrooms when you are ready to use them.
If you need to clean your mushrooms before use, it is best to gently brush away any visible dirt with a soft brush or cloth. Another option is to quickly rinse the mushrooms under cold water and then dry them thoroughly with a paper towel or clean cloth before storing them.
One effective way to store mushrooms in the fridge is to place them in a paper bag. Paper bags absorb excess moisture, helping to keep the mushrooms dry and fresh for longer. You can also wrap the mushrooms in paper towels and place them in an open container or bowl in the fridge. This method helps to absorb any moisture released by the mushrooms and prevents them from becoming slimy.
By avoiding washing mushrooms before storage and utilising appropriate storage methods, you can maximise the shelf life and maintain the quality of your mushrooms.

Cooked mushrooms last three days
Cooked mushrooms can be stored in the fridge for up to seven to ten days. However, it is important to note that they may last a little less time than this, and their lifespan will be reduced if they are included in a dish with other ingredients that spoil quickly.
To store cooked mushrooms, place them in an airtight container, as you would with any other cooked food. Before storing, it is important to monitor the mushrooms for any signs that they are going bad, such as dark spots, slime, odour, or wrinkles. If you notice any of these things, throw the mushrooms out.
If you wish to keep your mushrooms for longer, you can freeze them. To do this, first cook the mushrooms by blanching, sautéing, poaching, or steaming them. Then, freeze them on a parchment paper-lined baking sheet until they are frozen solid. Finally, transfer the frozen mushrooms to an airtight, vacuum-sealed plastic bag and store them in the freezer. Frozen mushrooms will keep for around nine to twelve months, but they may lose some nutritional value during this time.
There are also several methods for storing raw mushrooms in the fridge, which can help to extend their lifespan. One popular method is to store them in a paper bag, which helps to absorb excess moisture and maintain freshness. Another option is to wrap the mushrooms in paper towels and place them in an open plastic bag. Alternatively, you can remove the mushrooms from their packaging and layer them on cardboard drinks trays, which allows air to circulate and absorbs moisture.

Store on a shelf, not in a jar
Mushrooms have a high water content, so storing them in a jar or a bag that traps moisture will lead to rotting within a few days. The best way to store mushrooms is on a shelf in the fridge, in a breathable paper bag, which allows for better airflow and creates a less damp environment. Paper bags absorb the moisture that mushrooms naturally release, preventing them from getting slimy. They can also be placed in a paper towel-lined zip-top plastic bag, with the top left open, to absorb moisture.
If you are storing mushrooms for a few days, you can keep them in their original packaging, but be sure to punch some holes in the plastic wrap to allow them to breathe. Leaving them in the store packaging without holes will trap moisture and contribute to quicker spoilage.
It is also important to keep mushrooms away from strong-smelling foods in the fridge, as their porous, sponge-like nature will absorb odours.
