Do Mushrooms Need to Be Refrigerated? (How to Keep Fresh Longer)

Mushrooms are a type of fungus, and as such, they are highly perishable. The delicate nature of mushrooms requires that they be stored properly in order to maintain their flavor and texture.
So, do mushrooms need to be refrigerated? If you are not going to use your mushrooms right away, it is best to store them in a paper bag in the fridge. This will help to absorb any moisture that may cause the mushrooms to spoil. Be sure to check on your mushrooms regularly and use them within a few days; otherwise, they may start to spoil.
In this article, we will explain many good reasons why mushrooms need to be refrigerated. We will also brief you on how to do the proper storage to keep the mushrooms in tip-top condition.
Do Mushrooms Need to Be Refrigerated?
Fresh mushrooms should be stored in the refrigerator. If you are going to store mushrooms for a week or less, you can store them in the crisper drawer of your refrigerator.
Remove them from their original packaging before you keep mushrooms in the fridge. Put them in paper bags, not plastic. This allows the mushrooms to breathe and produce less moisture. It is crucial, as you want to keep mushrooms fresh for longer. Moisture will shorten the mushroomâs shelf life.
One important thing: before putting them in paper bags, donât wash them! Even if you wipe them with paper towels, youâre adding extra moisture. If they have some dirt on them, leave it alone. Just wash the mushrooms that youâll be using right away.
How Long Do Mushrooms Last in the Fridge?

After youâve picked your mushrooms, you might be wondering how long they will last in the fridge. The answer to that question depends on a few things, such as the variety of mushrooms and the way they were stored before you put them in the fridge.
Generally speaking, most mushrooms will last between three and five days in the fridge. However, if they were stored in a paper bag, they may only last for two or three days. If you have a vacuum-sealed package of mushrooms, they may last up to 10 days.
How to Store Mushrooms in the Fridge
The fridge is the better option to store mushrooms because it will keep them fresh for a longer period of time. If you store them in the pantry, they will only last for a few days.
Another reason to store mushrooms in the fridge is to extend their shelf life, keep them fresh, and maintain their taste until you cook them.
Below are steps to store mushrooms in the fridge.
- Before putting your mushrooms in the refrigerator, donât wash them. They will absorb more water, and the increased moisture will accelerate spoilage.
- Donât keep your mushrooms in the crisper drawer of the refrigerator, though, because of the moisture. These drawers are ideal for wilting lettuce or fresh herbs, but theyâre the worst place in the fridge to keep mushrooms.
- When keeping mushrooms in the fridge, keep them away from things that are particularly odorous or flavorful, like onions or fish. Mushrooms will absorb the smell like sponges.
- Donât pile anything else on top of your mushrooms. They canât take a lot of weight, so treat them like a loaf of bread. Squished, damaged mushrooms donât seem particularly appealing, and they wonât last long.
- There are some mushrooms that last longer in the refrigerator than others. To avoid wasting mushrooms, purchase them near the time you intend to use them.
- Consider freezing or drying mushrooms if you need to keep them for more than a week.
