Portobello mushrooms are a versatile ingredient, perfect for grilling, roasting, or adding to sandwiches as a meat substitute. Given their high water content, it is important to store them correctly to keep them fresh. But what is the best way to do this? Should they be refrigerated? Well, yes and no.

Portobello mushrooms should be stored in a paper bag in the refrigerator

Portobello mushrooms are a versatile ingredient, perfect for grilling, roasting, or adding to sandwiches as a meat substitute. To ensure they stay fresh for as long as possible, it's important to store them correctly. So, where's the best place to keep them? Well, it turns out that Portobello mushrooms should be stored in a paper bag in the refrigerator.

Firstly, let's talk about the bag. Mushrooms have a high water content, and as they age, they may start to release water. If you store them in an airtight container, this moisture has nowhere to go, and you'll end up with slimy mushrooms. A paper bag will absorb this excess moisture, keeping your mushrooms fresh and slime-free for longer. If you don't have a paper bag, you can also use a net bag, like the kind onions are often packaged in. Simply hang the bag from a hook or nail in your refrigerator.

Now, onto the refrigeration. It's generally agreed that mushrooms should be stored in the fridge. At room temperature, mushrooms will only stay fresh for a day or so. But in the fridge, they can last for up to 10 days. Just pop them on a shelf; there's no need to keep them in the crisper, as the high humidity of the crisper drawer is not ideal for mushrooms. If you want to be extra cautious, you can wrap the mushrooms in paper towels before placing them in a paper bag. The paper towels will help absorb any additional moisture.

One thing to keep in mind is that you should avoid washing your mushrooms before storing them. While some people advocate for rinsing mushrooms to remove any dirt or debris, others argue that washing can make mushrooms soggy. Since Portobello mushrooms are cultivated and grown in sanitized, composted peat moss, there's usually no need to worry about dirt. If you do choose to wash them, make sure they're completely dry before storing them in the paper bag.

They can be kept on the counter for a day but will last 7-14 days in the fridge

Portabella mushrooms are a versatile ingredient, adding depth to many dishes. To ensure they are at their best, it is important to store them correctly. Mushrooms are high in water content, so they should be refrigerated to keep them fresh. However, they can be left out on the counter for a day, but this is the maximum time recommended.

Leaving mushrooms out of the refrigerator for too long will cause them to spoil. They will last much longer if stored in the fridge, where they will keep fresh for up to two weeks. The ideal environment for storing mushrooms is cool and dry. The fridge is, therefore, a good option, but there are some additional steps to take to ensure they last as long as possible.

Firstly, it is important to ensure the mushrooms are dry. If they are wet, they will spoil faster. Secondly, they should be stored in a paper bag. This allows the mushrooms to breathe, and the bag will absorb any excess moisture. It is also possible to buy special net bags for storing mushrooms. These bags allow for ventilation, and the mushrooms can be hung up, which saves space.

Portabella mushrooms stored in this way will last for 7-14 days. It is also possible to freeze mushrooms, but this will affect their texture. Frozen mushrooms are best used in stocks or veggie burgers rather than fried.

Avoid storing in the crisper due to high humidity

Portabella mushrooms should be stored in the refrigerator to keep them fresh for as long as possible. However, it is recommended to avoid storing them in the crisper due to the high humidity levels typically associated with this section of the refrigerator.

Mushrooms are highly perishable and have a short shelf life. They should be stored in a way that minimises moisture retention, as moisture is the number-one enemy when it comes to keeping mushrooms fresh. While the crisper drawer in a refrigerator is a great option for storing many vegetables, it is not ideal for mushrooms due to the high humidity it maintains.

The high humidity in the crisper drawer can cause mushrooms to become slimy and discoloured. This is because mushrooms are highly porous and tend to absorb moisture, which can accelerate their spoilage. Therefore, it is best to avoid storing mushrooms in the crisper and opt for alternative storage methods that maintain ventilation and dryness.

One recommended method is to store mushrooms in a paper bag inside the refrigerator. The paper bag helps absorb any excess moisture released by the mushrooms, keeping them dry and fresh for longer. Another option is to place the mushrooms in a net bag, similar to those used for onions, and hang them from a hook or nail. This allows for air circulation and prevents moisture build-up.

Additionally, when storing mushrooms in the refrigerator, it is important to avoid airtight containers and plastic bags, as these can trap moisture and accelerate spoilage. Instead, opt for paper bags, net bags, or containers with perforations that allow for air circulation and moisture absorption. By avoiding the crisper drawer and utilising appropriate storage methods, you can extend the shelf life of portabella mushrooms and maintain their freshness and quality.

To clean, rinse in a colander, then dry with a towel

Portabella mushrooms should be cleaned before cooking. To do this, first remove the stems, which can be woody and unpleasant to eat. You can use a spoon, or you may need to use a small knife.

Next, place the de-stemmed mushrooms in a colander in your sink. Spray the mushrooms with water until any excess dirt and debris is gone. You can also use running water to rinse them, but be careful not to soak them, as they can become waterlogged and soggy.

After rinsing, lay the mushrooms out on a clean dish towel and let them dry completely. You can also use paper towels to pat them dry. Make sure the mushrooms are completely dry before storing them in the refrigerator.

Dehydrated mushrooms can be stored in a mason jar

Portabella mushrooms, like most mushrooms, are best stored in the refrigerator. They can be kept in a paper bag inside the fridge for up to 10 days. If you want to keep them for longer, you can dehydrate them.

Dehydrated mushrooms can last for up to a year, or even longer, if stored properly. They can be rehydrated by pouring boiling water over them, and then used in a variety of dishes.

If you live in a warm or humid climate, or you know you will not be using the dehydrated mushrooms frequently, it is best to store them in the refrigerator or freezer. Freezer storage can also help to keep bugs away from the mushrooms.
