Storing Mushrooms: The Best Ways To Keep Them Fresh

how to stire mushrooms

Mushrooms are a versatile ingredient, but they can be quick to spoil due to their high moisture content. The key to keeping mushrooms fresh is to avoid plastic containers and bags, which trap moisture and cause discolouration, mould, and slime. Instead, transfer mushrooms to a paper bag lined with a paper towel to absorb excess moisture and promote air circulation. They can be stored in the refrigerator for up to two weeks, although they may dry out over time. For short-term storage, the original packaging is fine for up to three days.

Avoid plastic containers and bags

When storing mushrooms, it is best to avoid plastic containers and bags. Plastic containers and bags trap moisture, which causes mushrooms to become slimy, discoloured, and mouldy.

If your mushrooms come in a sealed plastic container, take them out and store them using an alternative method. This is especially important if the plastic wrap does not have holes, as this can speed up spoilage. Mushrooms should be stored in a container that allows them to breathe.

Some mushroom producers package mushrooms in cardboard punnets covered with micro-perforated plastic film. This packaging is breathable and absorbs excess moisture, preventing the mushrooms from drying out. However, mushrooms stored in this packaging should be used within five to seven days, as they may start spoiling due to excess moisture.

Another option is to store mushrooms in a glass or plastic container covered with plastic wrap. However, this method does not keep mushrooms fresh for as long as other methods. When using this method, it is important to make holes in the plastic wrap to allow moisture to escape.

Paper bags are best

Paper bags are especially useful if you want to store mushrooms for a week or more. If you don't have a paper bag, you can also use a container lined with a paper towel on the bottom and another on top. The paper towels will absorb excess moisture and keep the mushrooms fresh for longer.

When storing mushrooms, it's also important to avoid the crisper drawer in your fridge, as this tends to be the most humid part. Instead, store mushrooms on the bottom shelf of your refrigerator, ensuring they have some airflow.

If you're short on time, you can keep mushrooms in their original packaging for up to three days. However, this is less than ideal, as the plastic packaging will trap moisture.

By following these storage tips, you can keep your mushrooms fresh and tasty for longer, reducing waste and ensuring you always have this versatile ingredient on hand.

Keep in the fridge

If you want to keep mushrooms in the fridge, it is best to avoid the crisper drawer, as this tends to be the most humid part of the fridge, and mushrooms are prone to rot in humid conditions. Instead, store them on the bottom shelf of your refrigerator. If you are planning on eating the mushrooms within a day or two, it is fine to keep them in their original packaging. However, for longer-term storage, it is best to transfer them to a paper bag lined with a paper towel. Paper bags are breathable and help to absorb excess moisture, keeping the mushrooms fresh for longer.

Make sure not to overcrowd the mushrooms in the bag, as they need some airflow to stay fresh. If you are storing loose mushrooms, it is worth transferring them to a paper bag as soon as you get home, to keep them fresh for a week or more. If you are storing cooked mushrooms, they can be kept in the fridge to be used throughout the week.

Avoid the crisper drawer

Mushrooms are best stored outside of the crisper drawer in the refrigerator. The crisper drawer, or vegetable drawer, tends to be too humid for mushrooms, which are around 80-90% water themselves and are highly susceptible to moisture loss or gain. This can cause them to become slimy and speed up the rate at which they spoil.

Instead, mushrooms should be stored in the main body of the fridge, where it is drier and cooler. They should be kept in a

Use paper towels

Mushrooms have a very high moisture content, which is why they are so quick to spoil. To prevent this, you can use paper towels to absorb the excess moisture.

One way to do this is to line a large glass bowl with paper towels, spread out the mushrooms, and cover them with another layer of paper towels. This allows you to check on the freshness of the mushrooms daily. However, this method may not be the most practical for storing mushrooms in the fridge.

A better method is to wrap the mushrooms in paper towels and place them in an open plastic bag. This method prevents the mushrooms from sitting in a damp container, which causes discolouration, mould, and slime. However, it is important to note that the paper towels and the plastic bag may become damp over time, trapping moisture rather than preventing it.

The best method for storing mushrooms is to use a breathable paper bag with a paper towel. This allows for much better airflow, creating a less damp environment for the mushrooms. The paper towel draws moisture away from the mushrooms, allowing them to last up to 10 days.
