Mushrooms are a versatile ingredient used in various dishes, from pasta to pastries. They are part of the fungi kingdom, which is separate from plants and animals, and have a high water content, making them prone to spoilage. The best way to store mushrooms is in the refrigerator, which slows spoilage and preserves their flavour. However, keeping mushrooms in the fridge for too long can cause them to become slimy and develop dark spots and mould. Therefore, it is important to monitor mushrooms for signs of spoilage and utilise proper storage techniques, such as wrapping them in paper towels and placing them in open plastic or paper bags, to extend their shelf life.

What You'll Learn
Mushrooms should be refrigerated
Mushrooms are a versatile ingredient used in cooking, especially in Asian and European cuisines. They are also a good source of vitamin D. However, they are delicate and perishable, so they need to be stored properly.
The best way to store mushrooms is in the refrigerator. Fresh mushrooms are high in water content, and their spongy texture means they can quickly become slimy and spoil. The refrigerator is the best place to keep them, but which spot you choose impacts preservation. Mushrooms should be stored in a porous container to promote air circulation, with paper towels to absorb excess moisture. They can be wrapped in paper towels and placed in an open plastic bag or brown paper bag. The brown paper bag method is preferred as it keeps moisture at bay, although some mushrooms may still develop dark spots.
If you've already sliced the mushrooms or bought them sliced, 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. If you are unable to use mushrooms within a week, consider freezing them. However, fresher mushrooms tend to freeze better, so it is recommended to lightly cook them first to preserve their quality and flavor.
Marinated mushrooms can be stored in the refrigerator for 10 to 14 days. To prepare marinated mushrooms, submerge them in olive oil, usually with lemon juice and other spices, then seal them in a glass jar. Dried mushrooms can be stored at room temperature and will last up to three years if stored properly.

Paper bags are best for storage
Mushrooms are a versatile ingredient used in cooking, especially in Asian and European cuisines. They are delicate and perishable, and can easily get slimy and spoil quickly due to their high water content. Therefore, it is important to store them properly. While the refrigerator is the best place to store mushrooms, paper bags are the best container for their storage.
Paper bags are the ideal container for storing mushrooms because they are porous and promote air circulation. This is important because mushrooms often thrive in damp, sealed environments. Paper bags also help to keep moisture at bay, preventing the mushrooms from becoming slimy. Additionally, paper bags allow ethylene gas to escape, which can cause mushrooms to spoil more quickly.
To store mushrooms in a paper bag, line the bag with a paper towel to absorb excess moisture. Place the mushrooms inside the bag and keep them in the refrigerator. This method will help to keep your mushrooms fresh and slime-free for up to 10 days.
It is also important to note that you should store mushrooms unwashed. Washing or soaking 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 or brush them with a pastry brush to remove any dirt or grime.
Additionally, the preparation of the mushrooms can impact their storage. If you are storing whole mushrooms, they will last up to a week. Sliced mushrooms should be stored in an airtight container and used within three days. If you are unable to use the mushrooms within this time frame, you can consider freezing them. However, fresher mushrooms tend to freeze better, so it is recommended to cook them lightly before freezing to preserve their quality and flavour.

Avoid glass containers
While storing mushrooms, it is best to avoid glass containers. Mushrooms are highly perishable due to their high water content, which makes them susceptible to slime formation and spoilage. To prevent this, it is important to promote air circulation and manage moisture levels.
Glass containers, being non-porous, can trap moisture inside and hinder airflow. This creates an ideal environment for the growth of bacteria and fungi, leading to quicker spoilage. Instead, it is recommended to use porous containers like paper or mesh bags, which allow air circulation and absorb excess moisture.
Paper bags, specifically brown paper bags, are effective in keeping mushrooms fresh. They absorb excess moisture, preventing the mushrooms from becoming slimy. Additionally, paper bags allow for some airflow, which helps regulate the moisture levels around the mushrooms.
Another option is to use mesh containers, which are particularly useful for drying mushrooms. By placing the mushrooms in a mesh container with good airflow, they can be air-dried effectively. Once completely dry, the mushrooms can be transferred to an airtight glass jar for long-term storage.
It is worth noting that while glass containers are not ideal for fresh mushroom storage, they can be used for marinated mushrooms. Marinated mushrooms are typically submerged in olive oil, sealed in a glass jar, and refrigerated. This method can extend the shelf life of mushrooms by up to two weeks.

Sliced mushrooms last three days
Firstly, it is important to note that mushrooms are delicate and perishable. They are made of 80 to 90 percent water, so they tend to spoil quickly and become slimy. Therefore, it is best to store them in a porous container that promotes air circulation. Paper bags are a good option, as they keep moisture at bay and prevent the mushrooms from spoiling too quickly.
If you plan to use the mushrooms within a week, you can store them in the refrigerator. Wrap them in paper towels and place them in an open plastic bag or, preferably, a paper bag. This will help to keep them fresh and prevent them from drying out.
However, if you want to store mushrooms for longer than a week, it is best to freeze or dry them. To freeze mushrooms, it is recommended to cook them first by lightly sautéing them in butter or steaming them. This will help preserve their quality and flavor. Then, freeze them on a parchment paper-lined baking sheet until they are frozen solid before transferring them to an airtight, vacuum-sealed plastic bag.
Drying mushrooms can be done using a dehydrator or by air-drying them. Place the mushrooms in a mesh container with good airflow for about a week, and once they are completely dry, store them in an airtight glass jar. Dried mushrooms can last up to three years when stored properly.

Wash mushrooms before refrigerating
When it comes to storing mushrooms, the refrigerator is the best place to keep them. However, it is important to wash mushrooms before refrigerating to remove any dirt or grime. Here are some steps you can follow to wash and store mushrooms properly:
Washing Mushrooms:
- Take a handful of mushrooms and hold them under running water to remove visible dirt and grime. Be careful not to submerge and leave them in the water for too long, as they will absorb the water and become mushy.
- Place the washed mushrooms on a paper towel or clean kitchen towel to absorb any dripping water.
- Use a paper towel to rub the mushrooms all over, drying them and removing any remaining grime, especially between the stem and cap.
Storing Mushrooms:
- Line a container with paper towels and place the washed mushrooms inside, covering them with another layer of paper towels to absorb excess moisture.
- Store the container of mushrooms in the refrigerator.
- Whole mushrooms stored this way should be used within a week, while sliced mushrooms should be used within three days.
Alternatively, if you don't have time to wash the mushrooms, you can place them in a paper bag for storage. However, washing the mushrooms and using paper towels will help keep them fresh for longer.
