What You'll Learn
Store in a paper bag
Storing mushrooms in a paper bag is an effective way to keep them fresh for up to 10 days. Mushrooms are quick to spoil due to their high moisture content, and the paper bag helps to absorb this excess moisture, keeping the mushrooms dry and firm.
To store mushrooms in a paper bag, place whole, unwashed mushrooms inside a brown paper bag and fold the top over to seal it. The paper bag will absorb any moisture released by the mushrooms, preventing them from getting soggy or mouldy. You can also line the paper bag with a paper towel, which will help to draw out additional moisture.
It is important to avoid washing mushrooms before storing them, as this can shorten their shelf life. Additionally, do not store mushrooms in the crisper drawer of your refrigerator, as this tends to be the most humid part of the fridge, creating a damp environment that can speed up spoilage. Instead, store the paper bag in the main compartment of your refrigerator, preferably on the bottom shelf.
By following these simple steps, you can keep your boughten mushrooms fresh and slime-free for up to 10 days, which is significantly longer than the typical 3-4 day shelf life when stored in their original packaging.

Avoid the crisper drawer
Mushrooms are best stored outside of the crisper drawer. This is because mushrooms are highly sensitive to ethylene gas, which is absorbed by the crisper drawer's seal, accelerating the spoilage of the mushrooms.
Instead, it is recommended to store mushrooms in a paper bag, or a cloth produce bag, and keep them in the

Use a net bag
If you want to keep your boughten mushrooms fresh for a week or more, it is recommended to transfer them to a net bag, such as the ones onions are often packaged in. This method is preferred over storing mushrooms in their original packaging, plastic bags, or glass containers. Net bags are breathable and allow for better airflow, creating a less damp environment for the mushrooms.
To use a net bag to store your mushrooms, simply place the mushrooms inside the bag and hang it from a hook or nail. If the mushrooms are placed in direct sunlight, they will absorb vitamin D. If you do not use the mushrooms right away, they will dry out, and you can reconstitute them.
You can also store mushrooms in a brown paper bag with a paper towel. The paper towel draws moisture away from the mushrooms, allowing them to last longer. However, the net bag method is considered the best way to store mushrooms and keep them fresh and slime-free for days.

Dehydrate and vacuum seal
If you want to store your mushrooms for a long time, you can dehydrate and vacuum seal them. Vacuum sealing can be an effective way to prolong the freshness and shelf life of both fresh and cooked mushrooms. This method is ideal for home cooks who buy mushrooms in bulk or those who want to preserve mushrooms for later use.
Firstly, you should only select fresh, high-quality mushrooms that are free from blemishes or signs of spoilage. Before dehydrating, gently clean the mushrooms without soaking them in water. Instead, use a damp cloth or soft brush to remove dirt and debris.
To dehydrate the mushrooms, bring a pot of water to a rolling boil and prepare an ice bath in a separate bowl. Add the mushrooms to the boiling water and blanch for two to three minutes. Quickly transfer the mushrooms to the ice bath to stop the cooking process. Drain well before placing them in vacuum seal bags, ensuring they are arranged in a single layer.
Make sure the mushrooms are completely dry before vacuum sealing. If they are still damp, they will rot. Once your mushrooms are dehydrated, place them in a vacuum seal bag. Using a vacuum sealing machine, remove the oxygen from the bag. Once the air is evacuated, seal the bag tightly to create an airtight environment.
Label and date the package, and store it in a cool, dry place. To rehydrate the mushrooms, simply pour a little boiling water over them, and they will be ready to use in your culinary creations!

Freeze them
Mushrooms can be frozen for up to nine months, but their texture and colour may change slightly. To freeze mushrooms, you can either freeze them raw or cooked. Freezing them raw will affect their nutritional value and texture, so it is recommended to cook them before freezing.
If you want to freeze raw mushrooms, scrub and brush them to remove any dirt, but do not wash them as they can become soggy. You can then slice them into similar-sized portions or leave them whole if they are small mushrooms. Place them on a tray and freeze them until they are solid. After they are frozen solid, transfer them to a labelled resealable freezer bag, expelling any excess air.
If you want to cook the mushrooms before freezing, you can steam blanch them or sauté them in a bit of neutral oil. Both methods are good for preserving nutrients. Steam blanching helps preserve produce by destroying enzymes that can increase how quickly foods spoil, and it also inactivates Listeria and Salmonella, two common foodborne bacteria. After cooking the mushrooms, flash-freeze them by placing the pieces onto a parchment paper-lined baking sheet and putting them in the freezer for about an hour, or until the pieces feel hard. Then, transfer the mushrooms to a labelled resealable freezer bag, ensuring you remove any excess air before sealing.
It is best to cook mushrooms from frozen as they have a high water content and can become soggy if defrosted.
