Properly storing mushrooms is essential to preserving their quality and flavor, but it can be challenging due to their delicate and perishable nature. The ideal location for storage is the refrigerator, but the exact spot you select can influence their longevity. Whole, raw mushrooms will keep from 4-7 days in the refrigerator, while sliced mushrooms (stored the same way) will last 1-2 days. However, freezing and dehydrating mushrooms are effective methods for long-term preservation.

Whole mushrooms can be stored in the refrigerator for up to two weeks
It is also possible to store mushrooms in their original packaging in the refrigerator, but changing the container can extend their shelf life. For example, placing them in a porous container with paper towels can help absorb excess moisture and promote air circulation, as mushrooms often thrive in damp, sealed environments. Additionally, vacuum sealing mushrooms can extend their shelf life up to three weeks.
If you are unable to use the mushrooms within a week, you can consider freezing them. However, fresher mushrooms tend to freeze better, so it is recommended to freeze them sooner rather than later. Before freezing, lightly sauté or steam the mushrooms to help preserve their quality and flavor. Then, freeze them on a parchment paper-lined baking sheet until they are frozen solid before transferring them to an airtight, vacuum-sealed plastic bag.
Another option for long-term preservation is dehydration. Dried mushrooms can last up to three years when stored properly at room temperature. However, freezing and dehydrating mushrooms may alter their texture and flavor, so it is essential to consider how you plan to use them before choosing a storage method.

Sliced mushrooms should be consumed within three to seven days
Sliced mushrooms are more delicate than whole mushrooms and have a shorter shelf life. It is recommended that sliced mushrooms be consumed within three to seven days of purchase. Storing sliced mushrooms properly can help extend their shelf life.
Firstly, it is important to note that mushrooms should be stored in a dry environment to prevent spoilage. Mushrooms have high water content, and if they are stored in a damp environment, they will release water and pull moisture from the air, leading to faster spoilage. Therefore, it is advisable to use a brown paper bag or paper towels to absorb excess moisture when storing mushrooms.
When storing sliced mushrooms, it is best to use an airtight container to prevent air circulation and keep them in the refrigerator. This will help to extend their shelf life. However, it is important to note that sliced mushrooms are more perishable than whole mushrooms and should be consumed within three to seven days, with some batches even going bad within five days.
To further extend the shelf life of sliced mushrooms, some people recommend freezing them. However, it is important to note that fresher mushrooms tend to freeze better, so freezing should be done sooner rather than later. Before freezing, it is recommended to lightly cook the mushrooms by sautéing them or steaming them to help preserve their quality and flavour.
When storing mushrooms, it is also important to avoid washing them before storage as this can shorten their shelf life. Instead, wipe down the mushrooms with a damp paper towel to remove any dirt or grime. Additionally, it is advisable to monitor mushrooms for any signs of spoilage, such as dark spots, slime, odour, or wrinkles, and to throw away any mushrooms that have gone bad.

Avoid plastic bags and sealed containers due to lack of airflow
Mushrooms are a versatile ingredient, but they can be challenging to store due to their delicate and perishable nature. They have a high water content, and their shelf life is short. To prevent quick spoilage, it is essential to avoid plastic bags and sealed containers due to the lack of airflow.
Mushrooms should be kept dry to prevent spoilage and prolong their shelf life. Plastic bags and sealed containers can trap moisture, creating a damp environment that promotes the growth of bacteria and fungi, leading to quicker spoilage. Instead, opt for porous containers that promote air circulation. Paper bags, paper towels, or bowls are ideal for storing mushrooms and absorbing excess moisture.
When storing mushrooms, it is also important to avoid washing them before storage. Washing mushrooms can cause them to absorb too much water, leading to faster spoilage. Instead, wipe them down with a damp paper towel to remove any dirt or grime.
Additionally, the storage method may vary depending on whether the mushrooms are whole or sliced. Whole mushrooms can be stored in a paper bag, while sliced mushrooms should be placed in an airtight container and consumed within a few days.
By avoiding plastic bags and sealed containers, you can ensure proper airflow and help extend the shelf life of your mushrooms.

Mushrooms should be kept dry and unwashed before storing
Mushrooms are a versatile ingredient in the kitchen, but they can be tricky to store due to their high water content and delicate nature. To keep mushrooms fresh, it is essential to keep them dry and unwashed before storing them.
Firstly, it is important to note that mushrooms should not be washed before storing. Washing mushrooms can cause them to absorb too much water, leading to faster spoilage. Instead, use a damp paper towel or brush to gently wipe or brush off any dirt or grime. This helps to extend their shelf life.
Secondly, mushrooms should be kept dry during storage. Mushrooms are prone to releasing water and pulling moisture from the air due to their high water content. To prevent this, store mushrooms in a porous container that promotes air circulation. Paper bags, paper towels, or bowls are ideal for this purpose. Avoid using plastic bags or sealed containers as they can trap moisture and speed up spoilage.
Additionally, it is recommended to store mushrooms in the refrigerator. The exact spot you choose can influence their longevity. Avoid the high-humidity setting of the crisper, as this is not ideal for mushrooms. Instead, opt for a middle or lower shelf, where the temperature is slightly warmer.
By following these steps and keeping mushrooms dry and unwashed before storing them, you can effectively extend their shelf life and maintain their quality and freshness.

Freezing and dehydrating mushrooms are effective methods for long-term preservation
Mushrooms are a versatile ingredient with a meaty texture and umami flavour. However, their delicate and perishable nature makes them challenging to store. Freezing and dehydrating mushrooms are two effective methods for long-term preservation.
Freezing Mushrooms
Freezing is a great way to preserve mushrooms and reduce food waste. It is best to freeze mushrooms as soon as possible after purchasing them, before any signs of decay. Mushrooms can be frozen cooked, steamed, or raw. Cooking or steaming them first will result in a nicer texture and more intact mushroom, as it draws out their internal moisture. To prepare mushrooms for freezing, they should be washed, trimmed, and cut into equal-sized pieces. They can then be sautéed in a pan with butter or oil, or steamed for a few minutes. After cooling, they should be placed in a single layer on a baking sheet and frozen. Once frozen, they can be transferred to a freezer bag or container, ensuring as much air is removed as possible. Frozen mushrooms should be used in cooked dishes, as freezing changes their structure and texture, making them unpleasant to eat raw.
Dehydrating Mushrooms
Dehydrating mushrooms is another effective preservation method, allowing them to be stored for several months. Dehydrators are recommended for the best results, but ovens can also be used. Before dehydrating, mushrooms should be cleaned thoroughly with a brush and rinsed with water. They can then be sliced into pieces between 1/4 and 1/2 inch thick, with thicker slices taking longer to dry. The slices should be arranged on drying trays so that no pieces are overlapping, allowing for even airflow. In a dehydrator, they should be dried at 110°F until crispy, while in an oven, the temperature should be set to 140°F. After drying, the mushrooms should be cooled and transferred to tightly sealed glass jars, labelled with the date and type of mushroom. To use, dehydrated mushrooms should be soaked in hot water for 20 to 30 minutes, resulting in a texture similar to fresh mushrooms.
