Mushrooms are a versatile ingredient, but they are also delicate and perishable. The best way to store white mushrooms is a topic of debate. Some sources suggest that mushrooms should be stored in the refrigerator, while others recommend storing them in a paper bag at room temperature. Those who advocate for refrigeration emphasize the need to prevent moisture buildup, which can lead to slime formation, by using paper towels or bags. On the other hand, those who suggest room-temperature storage believe that paper bags absorb excess moisture, keeping mushrooms fresh for longer.

What You'll Learn
Paper bags are best for storage
White mushrooms should be refrigerated. The refrigerator is the best place to store mushrooms. However, which spot you choose impacts their preservation. It is recommended to place them on a shelf in the fridge. The crisper drawer is not ideal because of the high humidity, which is not great for mushrooms.
Paper bags are best for storing white mushrooms. As mushrooms age, they may begin to release water. The paper bag absorbs this moisture, keeping the mushrooms' surface slime-free for longer. Paper bags are breathable, which helps to prevent the build-up of moisture. This is especially important as moisture is the number-one enemy when it comes to keeping mushrooms fresh. 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.
Another option is to use a net bag, like the ones onions are often sold in, and hang them from a hook or nail. This allows for air circulation while also keeping the mushrooms contained and off the counter.
If you are storing sliced mushrooms, use an airtight container in the refrigerator, and use them within three days. For whole mushrooms, use them within a week of purchase.
If you are unable to use the mushrooms within a week, you can freeze them. However, fresher mushrooms tend to freeze better, so it is recommended to cook them first. Lightly sauté them in butter or steam them before freezing to help preserve their quality and flavor.

Plastic bags should be avoided
White mushrooms should be refrigerated to keep them fresh for as long as possible. However, it is best to avoid storing them in plastic bags.
When storing mushrooms, it is important to keep them dry to prevent them from releasing water and spoiling. Plastic bags can trap moisture, creating an optimal environment for the growth of bacteria and fungi. This can cause the mushrooms to become slimy and mouldy, leading to food waste and potential health risks.
Mushrooms are highly perishable and have a short shelf life. To extend their freshness, it is crucial to choose the right storage method. Plastic bags can accelerate spoilage due to their inability to absorb moisture. As mushrooms age, they may start to release water, and a plastic bag will trap this moisture, making the mushrooms susceptible to slime formation and bacterial growth.
The use of plastic bags can also affect the quality of the mushrooms. Mushrooms are delicate, and the confined space of a plastic bag can cause them to bruise or crush easily. This can impact their texture and appearance, making them less appealing for culinary use.
Additionally, plastic bags can alter the flavour of the mushrooms. Mushrooms are known for their earthy and umami taste, but when stored in plastic bags, they may absorb unpleasant odours from the plastic or other items in the refrigerator. This can affect the overall taste and aroma of the mushrooms, diminishing their culinary value.
Instead of plastic bags, it is recommended to store mushrooms in paper bags or wrap them in paper towels. Paper absorbs excess moisture, helping to keep the mushrooms dry and fresh for a longer period. This storage method allows air circulation, reduces the risk of bacterial growth, and maintains the quality and flavour of the mushrooms.

Keep them in the fridge
Mushrooms should be stored in the fridge, but not in the crisper. The crisper is too humid for mushrooms, and they will absorb too much water, which is the number one enemy when it comes to keeping mushrooms fresh.
To keep mushrooms in the fridge, wrap them in paper towels and place them in an open plastic bag. Paper bags are even better than plastic, as they absorb the water that mushrooms release as they age, keeping the mushrooms' surfaces slime-free. If you don't have a paper bag, you can use a plastic bag, but make sure it is open and that you have placed a paper towel between the mushrooms and the bag.
If you have sliced your mushrooms, you should store them in an airtight container in the fridge. Sliced mushrooms should be used within three days, whereas whole mushrooms should be used within a week.
If you are unable to use your mushrooms within a week, you can freeze them. However, freezing mushrooms will likely affect their texture, so it is best to use frozen mushrooms for stock or to chop them into veggie burgers.

Don't wash them before storing
When storing white mushrooms, it is best not to wash them beforehand. Mushrooms are 80 to 90 percent water, and they absorb water like sponges. Therefore, washing them before storing them will shorten their shelf life. The goal of mushroom storage is to prevent them from releasing water and pulling moisture from the air.
To store mushrooms, it is recommended to wrap them in paper towels and place them in an open plastic bag or, even better, a paper bag. Paper bags are preferable because they absorb the moisture that mushrooms release as they age, keeping the mushrooms' surface slime-free. If you don't have a paper bag, you can place the mushrooms wrapped in a paper towel in a bowl in the refrigerator.
Another option is to put the mushrooms in a net bag, like the ones onions are often sold in, and hang them from a hook or nail. This method allows for air circulation and prevents moisture buildup, which can cause the mushrooms to spoil.
If you have sliced your mushrooms, it is best to store them in an airtight container in the refrigerator. Sliced mushrooms should be used within three days, while whole mushrooms should be used within a week of purchase.
Additionally, it is important to note that the refrigerator is the best place to store mushrooms, and they should be kept on a shelf rather than in the crisper, as the high humidity setting in the crisper is not ideal for mushrooms.

Freeze them to store long-term
If you want to store your white mushrooms for longer than a week, freezing them is a great option. Freezing mushrooms can extend their shelf life to up to a year. However, it's important to note that freezing will likely affect their texture and colour, making them softer and darker. Here's how to freeze white mushrooms:
Preparation:
Before freezing, clean the mushrooms. You can use a damp paper towel to wipe them down or lightly rinse them in cold water, ensuring you pat them dry afterward. Avoid soaking the mushrooms, as this can make them mushy. Some sources suggest that washing mushrooms before freezing can lead to freezer burn, so you may opt to simply brush off any visible dirt.
Cooking:
While you can freeze raw mushrooms, cooking them first may improve their shelf life. There are two recommended ways to cook mushrooms before freezing:
- Sautéing: Heat a frying pan with butter or oil over high heat. Cook the mushrooms for about five minutes, or until they are fully cooked and most of the liquid has evaporated.
- Steaming: To minimise discolouration, soak the mushrooms in a solution of one teaspoon of lemon juice or 1½ teaspoons of citric acid to one pint of water for five minutes. Then, steam the mushrooms according to the recommended steaming times.
Freezing:
Once the mushrooms are cooked, allow them to cool completely. Then, spread them out on a cookie sheet and flash-freeze them for at least two hours. Flash freezing ensures that the mushrooms freeze individually and do not clump together.
Storage:
After flash freezing, transfer the mushrooms to a freezer bag. Label the bag with the date, and store the bag horizontally in the freezer. Frozen mushrooms can last up to a year when stored this way.
Using Frozen Mushrooms:
When you're ready to use your frozen mushrooms, you have a couple of options. You can add them directly to a dish that will be thoroughly cooked, or you can thaw them overnight in the fridge before cooking. Frozen mushrooms are best suited for flavouring stocks, soups, or chopped veggie burgers. Their texture may not be ideal for frying or sautéing.
