The crisper drawer, sometimes called a humidity drawer, is a bin in your refrigerator that helps preserve the freshness of your fruits and vegetables by exposing them to different levels of humidity. The crisper drawer can be set to high or low humidity depending on the type of produce being stored. Mushrooms are best stored in a low-humidity environment as they are prone to rotting and spoilage in high-humidity conditions.

Mushrooms should be stored in a low-humidity drawer
The ideal refrigerator temperature for mushrooms is between 32-40°F, and they should be stored in a low-humidity environment. Picked mushrooms thrive in drier environments, and the high humidity of a crisper drawer could cause them to spoil quickly. Mushrooms are best stored in a paper bag or a paper towel-lined zip-top bag, which will absorb the moisture they naturally release, preventing them from becoming slimy.
When the crisper drawer is set to low humidity, airflow is maximized, allowing ethylene gas and excess moisture to escape from the drawer. This helps to prevent produce from ripening or rotting too quickly. Ethylene-sensitive vegetables and produce that are prone to wilting, such as cucumbers, fresh herbs, and leafy greens, should be stored in a high-humidity environment.
It is important to note that crisper drawers are designed to work best when they are about two-thirds full, allowing for optimal airflow. By storing mushrooms in a low-humidity drawer and following these additional storage tips, you can help keep them fresh for longer periods.

Mushrooms should be kept in a paper bag
Mushrooms should always be kept in a paper bag. They are part of the Fungal kingdom and have different storage requirements than plants. Mushrooms need to breathe to remain edible, and plastic bags prevent this, causing rapid bacteria growth. Paper bags, on the other hand, absorb any moisture, keeping mushrooms dry and safe to eat.
If you don't have a paper bag, you can wrap the mushrooms in a paper towel and place them in a bowl in the refrigerator. However, avoid using plastic containers or plastic wrap, as these can trap moisture and speed up spoilage.
Mushrooms should be stored in a dry, low-humidity environment, which helps them stay fresh longer. In a refrigerator, this means placing them in a crisper drawer set to low humidity. Crisper drawers are designed to preserve the freshness of fruits and vegetables by exposing them to different humidity levels. The low humidity setting in a crisper drawer allows ethylene gas and excess moisture to escape, extending the shelf life of produce that rots, such as mushrooms.
If you want to store mushrooms for the long term, you can freeze or dry them. Freezing mushrooms involves cooking and draining them, then packaging and sealing them before placing them in the freezer. Drying mushrooms involves using a dehydrator or air-drying them, then storing them in an airtight glass jar.

The ideal temperature for mushrooms is 32-40°F
Storing mushrooms in the fridge can be a tricky business. The ideal temperature for mushrooms is 32-40°F, and they should be placed in a low-humidity setting. Mushrooms are best kept in the refrigerator on a shelf, not in the crisper drawer, as they thrive in a dry, low-humidity environment. Crisper drawers are designed to control the airflow around fruits and vegetables, extending their lifespan by minimising or maximising airflow. They are meant for produce that rots or wilts easily.
The crisper drawer, sometimes called a humidity drawer, is a bin in your fridge that helps preserve freshness and may prolong the lifespan of your fruits and vegetables by exposing them to different levels of humidity. A crisper drawer can be set to high or low humidity depending on how you adjust its settings. When set to low humidity, you maximise airflow, and when set to high humidity, less air is allowed in.
Mushrooms are best kept in a dry, low-humidity environment. They should be stored in a paper bag or a paper towel-lined zip-top bag. The top of the bag should be folded over to enclose the mushrooms completely and prevent them from drying out. They should then be placed in the refrigerator on a shelf, not in the crisper drawer, and stored at 32-40°F for up to one week. It is important to note that the refrigerator door is typically the warmest location in the fridge, so mushrooms should be kept away from this spot.
The crisper drawer is designed to work best when it is about two-thirds full, so it is important not to pack it too tightly. This allows for optimal airflow and helps to prevent produce from rotting or wilting prematurely. In general, the high-humidity setting is ideal for produce that wilts easily, such as leafy greens, fresh herbs, and ethylene-sensitive fruits like strawberries. The low-humidity setting, on the other hand, is suitable for ethylene-producing fruits such as apples, pears, and avocados, which are prone to rotting.

Don't wash mushrooms until you're ready to use them
Mushrooms are best stored in a low-humidity crisper drawer. They are highly susceptible to moisture, so it is best not to wash them until you are ready to use them.
Mushrooms are porous and tend to soak up liquid like a sponge. This can result in a diluted flavour and a rubbery, slimy texture. If you wash mushrooms, it is important to ensure they are completely dry before cooking. This can be achieved by laying them out on a sheet pan lined with paper towels or kitchen towels for an hour or so.
Wild mushrooms, such as chanterelles or black trumpets, are likely to be dirty and require a rigorous cleaning. They should be washed thoroughly in water and then dried. Cultivated mushrooms, on the other hand, can be cleaned using a dry cloth or paper towel to wipe off any excess 'dirt'. They are usually cultivated in cedar, which is heat-treated to remove common plant pathogens like mould, bacteria, viruses, worms, and bugs.
Some people prefer to brush or peel their mushrooms instead of washing them. This is because washing mushrooms can make them soggy and affect their texture and flavour. However, food historian Harold McGee has disproved the belief that mushrooms will absorb too much water if they get wet.
To summarise, it is best to store mushrooms in a low-humidity crisper drawer and refrain from washing them until you are ready to use them. Wild mushrooms require a thorough washing and drying, while cultivated mushrooms can be cleaned with a dry cloth or paper towel.

Mushrooms are best stored on a shelf, not in the crisper drawer
The crisper drawer is a bin in your refrigerator that helps preserve freshness and prolong the lifespan of your fruits and vegetables by controlling the airflow that enters and exits the bin. This allows you to toggle between high and low humidity levels. High humidity keeps produce crisp, moist, and fresh for a longer period of time.
However, mushrooms are unique in that they require a dry, low-humidity environment to stay fresh. When stored in a high-humidity environment, mushrooms can spoil quickly and develop a slimy texture. Therefore, it is recommended to store mushrooms on a shelf in the refrigerator, rather than in the crisper drawer.
To ensure the freshest mushrooms, follow these steps: place them in a paper bag or a paper towel-lined zip-top bag. Roll the top of the bag down to allow the bag to stay open and place it in the refrigerator on a shelf. Make sure the refrigerator temperature is set between 32-40°F, which is the ideal temperature range for mushrooms. Do not wash the mushrooms until you are ready to use them, as they will absorb water and become slimy.
By storing mushrooms on a shelf in the refrigerator and following these simple tips, you can keep your mushrooms tasting fresh and prolong their lifespan.
