How to keep mushrooms fresh

Refrigerate fresh portobello mushrooms by placing them in paper bags or wrapping them in paper towels. Avoid using plastic wrap since it can trap moisture. Refrigerated portobello mushrooms should be consumed within a week.

It’s best to store the mushrooms intact and unpeeled in airtight plastic bag before storing them in the fridge. This will prevent them from becoming slimy and spoiling.

It’s also a good idea to store mushrooms out of the crisper drawer since it’s too humid, away from foods with strong odors, and don’t stack anything on top of them because they bruise easily!

It’s preferable to freeze your mushrooms (whole or sliced) if you plan to store them for more than a week. Mushrooms can be frozen for up to 6 months if cooked first and then placed in freezer-safe containers or bags.

How to Tell When Mushrooms Go Bad

  • They have grown slimy. When it’s time to identify freshness, the first rule of thumb is that if mushrooms are slimy, they’re no longer edible. Mushrooms that have sat in the fridge for long often get slimy. While they aren’t necessarily dangerous at this point, tossing them is still a good kitchen practice.
  • They form wrinkles. Older mushrooms may not get slimy, but instead dry out and wrinkle. While it’s fine to slightly dry out your mushrooms (because they’re already moist vegetables), you don’t want them to become too wrinkly. If they appear to be shriveled, it’s best to throw them rather than eat them.
  • They get darker or have black spots. Dark patches indicate that your fungus are beginning to rot. The greatest thing you can do is keep an eye on your mushrooms for the duration of their time in the fridge. It’s time to use them or lose them if you notice them turning darker or acquiring black patches.
  • They’ve lasted over 14 days. When it comes to mushroom shelf-life/storage duration, the widespread view is that two weeks in the fridge is the absolute maximum. Of course, you should use your best judgment and common sense. If they still look, smell, and feel good after more than two weeks, they’re generally safe to eat.
  • They have a distinct bad odor. Your mushrooms when fresh need not to have a strong or obvious odor. They’ve gone bad if you can smell them. Of course, you’ll detect a mushroom odor if you put your nose right up to them, but it should be mild and unobtrusive. You have rotten mushrooms if you take up the bag, open it, and have to turn your head. Get them out of here!
