How to store mushrooms the right way

Mushrooms are a delightful addition to any dish, but unless stored properly, they can spoil quickly. Knowing the best methods for storing mushrooms will help you keep them fresh for as long as possible. In this article, we'll discuss the different types of mushrooms, the best temperature and humidity for storing them, preparing them for storage, how to store them in the refrigerator and freezer, drying and preserving mushrooms, and how to troubleshoot common issues with storing mushrooms.

Types of Mushrooms and Their Storage Requirements

The first step to storing mushrooms is to understand the different types and how to store them. Store-bought mushrooms usually come in two varieties: white buttons (Agaricus bisporus) and creminis, which are simply mature white buttons. Both of these types should be stored in a paper bag, but they should not be washed until right before you use them. Oyster mushrooms (Pleurotus ostreatus) should be stored in a plastic bag, as they don't need the same amount of airflow as white buttons and creminis.

Other types of mushrooms, such as shiitake (Lentinula edodes) and maitake (Grifola frondosa), should be stored in a paper bag as well. These mushrooms should also not be washed until right before you use them. It is important to note that mushrooms should not be stored in the refrigerator, as this can cause them to become slimy and spoil quickly.

The Best Temperature and Humidity for Storing Mushrooms

When it comes to temperature and humidity, mushrooms should be stored at between 35-40°F (1.6-4.4°C) with a relative humidity between 90-95%. If your refrigerator doesn't have a temperature and humidity gauge, you can purchase one for around $20. It's important to keep your mushrooms stored in an environment that has stable temperatures and humidity levels to prevent spoilage.

When storing mushrooms, it is important to keep them in a sealed container or bag. This will help to maintain the desired temperature and humidity levels, as well as prevent any contamination from outside sources. Additionally, it is important to check the mushrooms regularly for any signs of spoilage, such as discoloration or a slimy texture. If you notice any of these signs, it is best to discard the mushrooms immediately.

Selecting and Preparing Mushrooms for Storage

When selecting mushrooms for storage, look for those that are firm to the touch and have an even color. Avoid any mushrooms that have soft or slimy spots, as they are likely spoiled. Once you've selected your mushrooms, it's important to properly prepare them for storage. Start by brushing off any dirt with a damp paper towel. If necessary, use a mushroom brush for any stubborn dirt particles. Once all the dirt is removed, let the mushrooms air dry for about 10 minutes before storing.

When storing mushrooms, it is important to keep them in a cool, dry place. Place the mushrooms in a paper bag or a container with holes in it to allow for air circulation. If you plan to store the mushrooms for more than a few days, it is best to place them in the refrigerator. This will help to keep them fresh and prevent them from spoiling. Be sure to check the mushrooms regularly for any signs of spoilage, and discard any that have gone bad.

Refrigerator Storage Tips for Mushrooms

Once your mushrooms are properly prepared, it's time to store them in the refrigerator. For white buttons and creminis, place them in a paper bag and loosely fold over the top. For oyster mushrooms, store them in a loosely sealed plastic bag. Place the bag of mushrooms in the crisper drawer of your refrigerator, away from any direct sources of heat.

It's important to check your mushrooms regularly for any signs of spoilage. If you notice any discoloration or a sour smell, discard the mushrooms immediately. Additionally, make sure to use the mushrooms within a few days of storing them in the refrigerator, as they will not keep for an extended period of time.

Freezer Storage Tips for Mushrooms

If you're planning to freeze your mushrooms, it's important to blanch them first. To blanch mushrooms, bring a pot of lightly salted water to a boil and add your mushrooms. As soon as the water returns to a boil, remove the pot from the heat and strain the mushrooms. Let the mushrooms cool completely before transferring them to an airtight container or freezer-safe bag. Place the container in the coldest part of your freezer.

When you're ready to use your frozen mushrooms, it's best to thaw them in the refrigerator overnight. This will help to preserve the flavor and texture of the mushrooms. Once thawed, use the mushrooms within a few days. If you need to store them for longer, you can refreeze them, but this may affect the quality of the mushrooms.

Drying and Preserving Mushrooms

If you want to extend the shelf life of your mushrooms even further, drying them is a great option. Start by spreading your clean and dry mushrooms on a baking sheet lined with parchment paper. Place the baking sheet in an oven preheated to 150°F (65°C) for about 3 hours. Once fully dried, place the dried mushrooms in an airtight container and store at room temperature.

When you are ready to use the dried mushrooms, you can rehydrate them by soaking them in warm water for about 20 minutes. Once rehydrated, the mushrooms can be used in any recipe that calls for fresh mushrooms. You can also grind the dried mushrooms into a powder and use it as a seasoning or to add flavor to soups and sauces.

Troubleshooting Common Issues with Storing Mushrooms

If you find that your mushrooms are slimy or have black spots on them, they have likely gone bad. If you notice any of these signs, immediately discard the affected mushrooms. If your mushrooms have a sour smell or have started to shrivel, they may have been exposed to too much humidity while being stored. To avoid this issue, make sure you store your mushrooms in containers or bags with enough room for air circulation.

It is also important to store mushrooms in a cool, dry place. Avoid storing them in the refrigerator, as this can cause them to become slimy and spoil quickly. If you need to store mushrooms for a longer period of time, consider freezing them. To do this, place the mushrooms in a single layer on a baking sheet and freeze them for a few hours. Once frozen, transfer them to an airtight container or bag and store in the freezer.

Conclusion

Storing mushrooms correctly is essential to keeping them fresh for longer. By understanding the different types of mushrooms and their storage requirements, selecting and preparing them correctly for storage, storing in the refrigerator or freezer, drying and preserving them, and troubleshooting common issues with storing mushrooms, you can easily keep your mushrooms fresh for longer.
