Mushrooms have a short shelf life and can be challenging to store due to their delicate and perishable nature. They are made of 80 to 90 percent water and have a porous texture, so they must be kept dry to stay firm and fresh. This article will explore the best ways to keep sliced mushrooms fresh and full of flavor.

What You'll Learn
Use paper towels to absorb moisture
Keeping sliced mushrooms fresh can be challenging due to their delicate and perishable nature. One effective way to prolong their shelf life is to use paper towels to absorb moisture.
To do this, line a large glass bowl with paper towels and spread out the sliced mushrooms in a single layer. Cover them with another layer of paper towels. This method allows air to circulate and helps to absorb excess moisture, preventing the mushrooms from becoming slimy.
Food writer Harold McGee recommends this approach in his culinary science book, 'On Food and Cooking'. It is a significant improvement over using plastic wrap or bags, which can trap moisture and accelerate the growth of slime.
While this method can help extend the freshness of sliced mushrooms, they should still be used within three days for optimal quality. If you need to store them for a more extended period, consider freezing or dehydrating them.
By following these instructions, you can effectively use paper towels to absorb moisture and keep your sliced mushrooms fresh for a few days.

Store in a glass bowl, not plastic
Storing sliced mushrooms in a glass bowl is a much better option than using plastic. Mushrooms are 80 to 90 percent water, and they have a porous texture, so they soak up water easily. They must be kept dry to stay firm and fresh.
Using a glass bowl allows you to check the freshness of the mushrooms daily. It is recommended to line the bowl with paper towels, spread out the mushrooms, and cover them with another layer of paper towels. This will help to absorb any excess moisture and keep the mushrooms dry.
In contrast, plastic containers or bags can trap moisture, leading to quicker spoilage. The trapped moisture can also create an ideal environment for bacteria to grow, resulting in a slimy layer forming on the mushrooms.
If you plan to store mushrooms for an extended period, freezing is an effective method. Sliced mushrooms can be tossed in oil, soy sauce, garlic powder, and herbs, and then frozen. This method will allow you to enjoy the mushrooms for weeks.
Additionally, it is important to note that washing mushrooms before storing them can shorten their shelf life, so it is best to avoid doing so.

Freeze sliced mushrooms
Freezing sliced mushrooms is a great way to reduce food waste and keep them fresh for longer. Here is a step-by-step guide on how to do it:
Step 1: Clean and Prepare the Mushrooms
Start by wiping the mushrooms with a damp paper towel to remove any dirt. You can also trim off any dried-out parts of the stems or remove them entirely, especially for certain types of mushrooms like chanterelle, shiitake, and portobello.
Step 2: Slice the Mushrooms
Most mushrooms should be sliced before freezing. Cut them into similar-sized pieces to ensure even cooking or steaming. Smaller mushrooms can be left whole if they are less than one inch in diameter.
Step 3: Cook the Mushrooms (Optional)
You can choose to freeze mushrooms raw or cooked. Cooking them helps preserve their quality and flavour. To cook, you can sauté them in a skillet with a little butter or oil for about 5 minutes. Alternatively, steam them by placing them in a steamer basket over boiling water for 3 to 5 minutes. Let the mushrooms cool completely after cooking.
Step 4: Soak Mushrooms in Lemon Water (Optional)
For better colour retention after freezing, soak the mushrooms in a solution of water and lemon juice before cooking. Use a ratio of 2 cups of water to 1 teaspoon of lemon juice and soak for about 10 minutes.
Step 5: Freeze the Mushrooms
Once the mushrooms are cleaned, sliced, and optionally cooked and soaked, it's time to freeze them. Spread them out on a tray or baking sheet, ensuring they are not stacked to promote even freezing. Place the tray in the freezer until the mushrooms are frozen solid.
Step 6: Transfer to Freezer Bags
After the mushrooms are frozen solid, transfer them into labelled resealable freezer bags. Remove as much air as possible from the bags before sealing. You can also use freezer-safe containers.
Storage and Usage:
Frozen mushrooms can be stored for up to 6 months, although some sources suggest they are best used within 3 months. When cooking, use them directly from frozen, adding them to dishes like stews, casseroles, pasta bakes, stir-fries, soups, or risottos. Increase the cooking time slightly to ensure they are cooked through and to steam off any excess water absorbed during freezing.

Don't wash mushrooms before storing
When it comes to keeping sliced mushrooms fresh, there are a few things to keep in mind. Firstly, it is recommended to avoid washing mushrooms before storing them, as moisture is considered the number one enemy of mushroom freshness. Mushrooms have a porous texture and can soak up water like a sponge, leading to faster spoilage.
To maintain freshness, it is best to keep mushrooms dry. One effective method is to use paper towels. Line a large glass bowl or container with paper towels, spread out the sliced mushrooms, and then cover them with another layer of paper towels. This setup allows for daily freshness checks, and the paper towels absorb excess moisture, helping to keep the mushrooms fresh.
Another recommended storage method is to use a brown paper bag. Simply place the unwashed sliced mushrooms in the bag and fold the top over to seal. The paper bag will absorb any moisture, creating a dry environment that helps keep the mushrooms fresh.
If you're looking for longer-term storage, freezing is an option. However, it is best to cook the mushrooms first to preserve their quality and flavor. Lightly sauté them in butter or steam them before placing them in a freezer-safe bag and storing them in the freezer for up to 12 months.
By following these storage methods and avoiding washing mushrooms before storing them, you can extend the shelf life of sliced mushrooms and maintain their freshness.

Store in a net bag
Storing sliced mushrooms in a net bag is an effective way to keep them fresh and dry. The net bag allows for air circulation, which helps to prevent the mushrooms from becoming slimy and spoiled. It is best to avoid washing mushrooms before storing them, as moisture is the number one enemy of fresh mushrooms.
To store sliced mushrooms in a net bag, start by placing the mushrooms in a net bag, such as the kind that onions are often packaged in. Hang the bag from a hook or nail in a well-ventilated area. If possible, hang the bag near a window, as the sunlight will help to keep the mushrooms dry and can even increase their vitamin D content.
It is important to note that storing mushrooms in a net bag may not keep them fresh for as long as other methods, such as freezing or dehydrating. Sliced mushrooms stored in a net bag should be used within a few days to ensure optimal freshness and to prevent spoilage.
Additionally, it is worth mentioning that this storage method works best for whole mushrooms. If you are storing sliced mushrooms, it might be preferable to use a different storage method, such as freezing or dehydrating, to prolong their shelf life.
