What You'll Learn

Whole mushrooms can be stored in the fridge for 4-7 days
When storing whole mushrooms, it is important to keep them unwashed. Washing or soaking the mushrooms before storage can cause them to absorb too much water, leading to faster expiration. Instead, wipe down the mushrooms with a damp paper towel to remove any dirt or grime.
If you buy mushrooms pre-packaged, you can simply pop them into the fridge. The package's perforation will allow air to circulate and dry out any moisture released by the mushrooms. However, if you plan to store them for more than a few days, it is recommended to transfer them to a paper bag or porous container to extend their shelf life.
Additionally, it is important to regularly check the mushrooms for any signs of spoilage, such as dark spots, slime, odour, or wrinkles. If you notice any of these indicators, it is best to discard the mushrooms and not consume them.
By following these storage guidelines, you can keep your whole mushrooms fresh and flavourful for 4-7 days in the refrigerator.

Sliced mushrooms can be stored in the fridge for 1-3 days
Sliced mushrooms should be stored in an airtight container in the refrigerator. They will last for 1-3 days. Whole, raw mushrooms stored in the same way will last for 4-7 days.
It is important to note that the longer mushrooms are kept in the fridge, the more likely they are to develop dark spots and mould. This is due to their high water content, which means they can quickly become slimy. To prevent this, it is recommended to store mushrooms in a paper bag or porous container that allows for air circulation and absorbs excess moisture.
Some sources suggest that sliced mushrooms can be stored in the fridge for up to a week. However, this may depend on the freshness of the mushrooms when purchased and the humidity of the refrigerator. If you are unable to use sliced mushrooms within a few days, it is recommended to cook and freeze them to extend their shelf life.
To prepare mushrooms for storage, wipe them down with a damp paper towel to remove any dirt or grime. Do not wash or soak the mushrooms, as this can cause them to absorb too much water and spoil faster.

Avoid plastic bags and sealed containers
Keeping mushrooms in the fridge is a great way to keep them fresh for longer. However, it is important to avoid plastic bags and sealed containers when storing mushrooms. This is because mushrooms have a high water content and are porous, meaning they can easily absorb water and trap moisture. Plastic bags and sealed containers can speed up spoilage due to the lack of airflow, resulting in the mushrooms becoming slimy and developing dark spots and mould.
Mushrooms should be stored in a well-ventilated container to promote air circulation and prevent the build-up of moisture. Paper bags are an excellent alternative to plastic bags as they are porous and allow air to circulate while absorbing excess moisture. Paper bags help to keep the mushrooms' surface slime-free and can extend their shelf life. If using a paper bag, fold the top over to seal it and place the bag in the refrigerator.
If you don't have a paper bag, you can also wrap the mushrooms loosely in a paper towel and place them in a bowl or open container in the fridge. The paper towel will absorb moisture, helping to keep the mushrooms fresh. Another option is to use cardboard, such as the cardboard drinks trays from coffee shops, which can be stacked in the fridge. This allows for air circulation and absorbs any potential moisture.
It is also important to note that mushrooms should be stored unwashed. Washing or soaking mushrooms before storage can cause them to absorb too much water, leading to faster spoilage. Instead, wipe down the mushrooms with a damp paper towel to remove any dirt or grime.

Use paper bags or paper towels to absorb excess moisture
When storing mushrooms, it is important to remember that they are made up of 80 to 90 percent water. This means that moisture is the number one enemy when it comes to keeping mushrooms fresh. To prevent spoilage, it is recommended to use paper bags or paper towels to absorb excess moisture.
Paper bags are a popular choice for storing mushrooms. They can be brown paper bags or regular paper bags. The bag will absorb any moisture released by the mushrooms, keeping them safe and fresh. It is best to avoid plastic bags and sealed containers as they can trap moisture and speed up spoilage. If using a paper bag, fold the top over to seal it and place it in the refrigerator.
If you don't have a paper bag, you can use paper towels. Wrap the mushrooms loosely in a paper towel and then place them in a bowl or open container in the refrigerator. The paper towel will absorb moisture, helping the mushrooms stay fresh. You can also place the paper towel-wrapped mushrooms in a plastic bag, but make sure to punch a couple of holes in the plastic to allow air circulation.
It is important to note that mushrooms should be stored unwashed. Washing or soaking mushrooms before storage 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, it is recommended to use whole, unwashed mushrooms for storage as they tend to last longer than sliced mushrooms.
By using paper bags or paper towels to absorb excess moisture, you can effectively extend the shelf life of your mushrooms and maintain their freshness.

Frozen mushrooms can be stored for up to 12 months
Fresh mushrooms are a versatile staple in any kitchen, known for their meaty texture and umami flavor. They are highly perishable and should be consumed as fresh as possible. The ideal location for storing mushrooms is the refrigerator, though the exact spot you select can influence their longevity.
Mushrooms are made of 80 to 90 percent water and have a porous texture, meaning they soak up water like a sponge. Hence, moisture is the number-one enemy when it comes to keeping mushrooms fresh. They should be stored in a brown paper bag inside the refrigerator to absorb excess moisture and maintain freshness. They can be kept in the refrigerator for about a week before they start showing signs of expiry.
Freezing mushrooms is a great way to prolong their shelf life and reduce food waste. The fresher the mushrooms when frozen, the better they'll keep in the freezer. Before freezing, brush off any visible dirt and trim their stems. Then, lightly sauté or steam them before dipping them in a solution of 1 pint of water and 1 teaspoon of lemon juice to preserve their colour. Finally, place the cooled mushrooms in a freezer-safe bag and store them in the freezer for up to 12 months. Frozen mushrooms are best suited for cooked dishes such as soups, casseroles, stews, or pizza toppings.
