Mushrooms are a versatile ingredient, but they are also delicate and perishable. The best way to store mushrooms is in the refrigerator, but not in an airtight container. The ideal storage method will keep them fresh and free of slime and mould. Mushrooms should be stored in a paper bag, or wrapped in a paper towel and placed in a bowl in the refrigerator. They can also be stored in a net bag and hung from a hook or nail. If stored properly, mushrooms can last for several weeks, but they will eventually dry out and lose weight.

In the fridge, in a brown paper bag
Storing mushrooms in a brown paper bag in the fridge is an effective way to keep them fresh for longer. Mushrooms are delicate and perishable, so it is important to know how to store them properly. The brown paper bag method is preferred by food writer Harold McGee, who recommends transferring the mushrooms from their original container into a brown paper bag and placing them in the fridge.
The paper bag absorbs any moisture released by the mushrooms as they age, keeping their surface dry and preventing the formation of slime. This method is an improvement on storing mushrooms in a plastic container, which can trap moisture and speed up spoilage. The paper bag also allows for ventilation, which helps to keep the mushrooms fresh.
However, it is worth noting that this method may not keep the mushrooms in perfect condition. In one test of this method, the mushrooms were dry and slightly wrinkly after 10 days, with four out of the batch developing dark spots. That being said, the tester cooked and ate the mushrooms, finding that the wrinkly mushrooms had a deep, earthy flavour.
If you are planning to store mushrooms in the fridge in a brown paper bag, it is recommended that you use them within a week of purchase. If you are unable to use them within this time frame, you can consider freezing them. To do this, lightly sauté or steam the mushrooms before placing them in a freezer-safe bag and storing them in the freezer for up to 12 months. Another option is to dry the mushrooms, which can be done by air-drying them in a mesh container for about a week before transferring them to an airtight glass jar.

In a net bag, hung near a window
If you want to store mushrooms in a net bag, hung near a window, there are a few things you should know. Firstly, mushrooms are delicate and perishable, so they need to be stored correctly to maximise their usability and keep them fresh. Mushrooms are high in water content, so they can quickly become slimy and spoil if not stored properly.
Storing mushrooms in a net bag, hung near a window, is a good way to keep them fresh. The net bag allows the mushrooms to breathe and prevents them from being in a damp container, which can cause discolouration, mould, and slime. Hanging the bag near a window is beneficial because mushrooms will absorb vitamin D from the sunlight. However, it is important to note that the mushrooms will dry out if left for too long, so they should be used promptly or reconstituted before use.
To store mushrooms in a net bag, you can reuse the type of bag that onions are often packaged in. Simply place the mushrooms in the bag and hang it from a hook or nail near the window. This method is a good option for short-term storage, as it will keep the mushrooms fresh and allow them to absorb vitamin D.
It is important to note that this storage method may not be suitable for all types of mushrooms, and the shelf life of mushrooms stored in a net bag may vary depending on the type of mushroom and other factors such as temperature and humidity levels. If you are planning to store mushrooms for an extended period, you may want to consider alternative storage methods such as using a paper bag or airtight container in the refrigerator, or even freezing or drying the mushrooms.
Overall, storing mushrooms in a net bag, hung near a window, can be a convenient and effective way to keep them fresh in the short term, while also providing the added benefit of vitamin D absorption. However, it is important to monitor the mushrooms regularly and use them promptly to prevent them from drying out or spoiling.

In a plastic bag, partially open
Mushrooms are a versatile ingredient, but they are delicate and perishable. They have a high water content, which means they can quickly become slimy and spoil. To prevent this, it is important to store mushrooms in a way that maintains the right moisture content.
One option is to store mushrooms in a partially open plastic bag. Zip-lock bags are ideal because the opening can be kept open by only partially closing the zip. It is important that the bag is not completely closed, as this can cause the mushrooms to spoil. Plastic bags retain the mushroom's moisture, but the opening allows some of the moisture to be removed by the refrigeration process. This method can help to keep the mushrooms fresh for longer.
However, it is worth noting that plastic bags are not the only option for storing mushrooms. Some sources recommend using a brown paper bag, which can absorb the moisture released by the mushrooms as they age, helping to keep them slime-free. Others suggest using a net bag, which can be hung from a hook or nail, allowing the mushrooms to absorb vitamin D from sunlight.
Regardless of the storage method, it is important to buy the freshest mushrooms possible and to use them within a few days. Whole mushrooms will typically stay fresh longer than pre-sliced mushrooms. If you are unable to use the mushrooms within a week, you can also consider freezing them, although this may affect their texture.

In a glass bowl, lined with paper towels
If you're wondering how to store mushrooms to keep them fresh for as long as possible, consider using a glass bowl lined with paper towels.
This method creates a humid environment that mimics the conditions in which mushrooms thrive. By lining a glass bowl with paper towels, you create a moist environment that prevents the mushrooms from drying out while still allowing excess moisture to evaporate. This helps maintain the ideal humidity level, keeping the mushrooms fresh and delaying the onset of spoilage.
To use this storage method, start by dampening a few paper towels with water. Make sure they are damp but not soaking wet. Gently line the bottom and sides of a clean glass bowl with the damp paper towels. Place the mushrooms in a single layer on the paper towels, taking care not to crowd them. Cover the bowl with a lid or plastic wrap, ensuring that it is not airtight, as ventilation is important.
Store the prepared glass bowl in the refrigerator, ideally in a crisper drawer or on a shelf away from direct airflow. Check on the mushrooms periodically, replacing the paper towels as needed to maintain humidity. With this storage method, you can expect your mushrooms to stay fresh for up to a week or even longer, depending on the initial freshness of the mushrooms.
Additionally, it's worth noting that this storage method works well for most types of mushrooms, including button, cremini, portobello, shiitake, and oyster mushrooms. However, it is essential to inspect the mushrooms before each use, discarding any that show signs of spoilage to ensure you only consume fresh, high-quality mushrooms. By following these simple steps and storing your mushrooms in a glass bowl lined with paper towels, you can extend their shelf life and enjoy their freshness for several days.

In the freezer, after cooking
Freezing cooked mushrooms is a great way to extend their shelf life. Here is a detailed guide on how to do it:
Preparation:
Before cooking the mushrooms, it is important to clean them thoroughly. Use a damp paper towel, a pastry brush, or a quick rinse with water to remove any dirt, but be sure to dry them completely afterwards. Mushrooms absorb moisture easily, so you want to avoid any excess water. You should also trim any woody parts from the stems and cut larger mushrooms into uniform pieces. Smaller mushrooms can be left whole.
Cooking:
Cooking the mushrooms before freezing helps to remove moisture and improve their texture and flavour. There are two recommended methods for cooking: sautéing or steaming. To sauté the mushrooms, use a small amount of neutral oil or butter in a pan over medium heat. Cook the mushrooms until they are fork-tender and the pan is mostly dry. The mushrooms will release moisture, which will then evaporate. Alternatively, you can steam the mushrooms by soaking them in a bowl with water and a teaspoon of lemon juice to prevent discolouration. Place the mushrooms in a steamer basket over boiling water and steam for 3 to 5 minutes until cooked.
Cooling:
Once the mushrooms are cooked, allow them to cool completely before freezing. This step is important to prevent moisture buildup in the freezer. Spread the cooled mushrooms onto a parchment paper-lined cookie sheet and place them in the freezer for about an hour, or until they are frozen solid.
Freezing:
After the mushrooms are frozen, transfer them to freezer-safe bags or containers. Squeeze out as much air as possible to prevent freezer burn and prolong their shelf life. Label the bags or containers with the date and aim to consume the mushrooms within 9 to 12 months for the best quality. Frozen cooked mushrooms are perfect for adding to soups, stews, sauces, stir-fries, or veggie burgers.
Tips:
- For improved colour after freezing, dip the mushrooms in a solution of 1 pint of water and 1 teaspoon of lemon juice before cooking.
- If you prefer to freeze fresh mushrooms, flash freezing is recommended. Place the individual mushrooms on a lined cookie sheet and freeze until solid, then transfer to a freezer-safe container.
- Avoid washing mushrooms before storing them, as moisture is the enemy of fresh mushrooms.
