So you have bought or picked some fresh mushrooms and now you’re thinking about how much time they can spend chilled you may ask if you put them into. Or is it better to leave them on the countertop?

  • First of all, don’t leave the mushrooms at a too warm temperature or in the surrounding with too high moisture. They can easily get dry in the first case and rotten in the latter. Crisper drawer won’t work for the same reasons. For refrigerating, use either their native package or put the mushrooms in a paper perforated bag. Keep them away from any strong-smelling food in the fridge as mushrooms pick the external odors easily
  • For freezing, wash and brush them to delete any dirt and then slice and saute. Only when cooked mushrooms can be frozen! After they cool down, put mushrooms in a plastic bag and toss them to the freezer.

If we are talking about the marinated mushrooms bought from a store, simply follow the storage instructions indicated in the jar label and remember that these veggies can’t be consumed after their expiry date has passed!

Signs of Spoiled / Rotten Mushrooms

Everyone knows that eating spoiled or rotten mushrooms is dangerous since they can make you very sick. If the mushrooms you eat are store-bought, the risk of food poisoning is very low, and they pose even less risk if you eat them cooked. But if you like using mushrooms (especially fresh ones) in your dishes at home, you should be aware of the signs of spoilage/rot to avoid severe food poisoning!

Luckily, it’s easy to tell the difference between fresh and bad mushrooms. Fresh mushrooms are dry and firm, with a smooth and pleasant earthy smell. But when mushrooms start decaying, they become softer and often mushy.

Also, they develop a sticky and slimy residue. Bad mushrooms can also be shriveled, moldy, and discolored. The smell will also be very unpleasant.

First of all, keep in mind that fresh mushrooms can stay fresh for about a week if you keep them in the refrigerator. However, depending on the variety, the actual storage time might be from four days up to ten days.

Finally, if your goal is to keep a batch of mushrooms consumable as long as possible, consider freezing them. Low temperatures work great for keeping foods fresh and useful without causing damage to their texture. 

If you freeze mushrooms, most of them will last in your freezer for 9–12 months.

However, if you choose to freeze as a storage method, note that frozen mushrooms are most suitable for dishes that will be cooked because their texture may change a bit after thawing.

This is why we recommend adding them to soups, casseroles, or stews, or as a pizza topping.

Never buy mushrooms that are already packed in a container

Well, at least try not to buy them like this. Instead, search for those that are sold loose. First, it will allow you to buy as much as you need and not to pay for extra unnecessary content. And second, loose fungi cost less. Besides, you can quickly examine loose ones to skip dark spots and check them for freshness.

Choose the right container

If you choose a plastic packet as a container for the fungi, then throw it away right now. This package makes air inside too moist making the content turn slimy quickly.

For the same reason, never toss them to the crispy container at the bottom of the fridge. An airtight container will also not work since it prevents moisture from evaporating which leads to dark spots to appear.

Instead, keep them in a paper bag open since it absorbs the excess moisture and lets the air circulate, and you’ll forget about the slimy fungi.

Choose the right container

Put them away from smelly foods

Never place fungi together with:

  1. herbs,
  2. cheese,
  3. strong-smelling things since they are quick in intaking odors

Clean them properly

Darners absorb water like sponges that’s why rinsing is not the correct option for cleaning them. Besides, excess moisture will make the fungi slimy with those dark dots around.

So if the plan is to consume them raw, just brush off the dirt with a dry paper towel (you can dampen it if the fungi are very dusty or have soil on them).

For the recipes that ask for cooking them, rinse darners and tap dry with a paper napkin.

Fry correctly

Mushrooms need space when being cooked so don’t crowd the pan when frying them for your recipes if you don’t like eating soggy darners. Also, these veggies need enough fat to be properly cooked so use enough oil/butter, otherwise, they’ll turn dark and shrivel a lot (that’s the sign that the pan is too dry).

These hints point to the most common mistakes that can be done when working with recipes that need mushrooms or when keeping fungi. Keep those in mind and you’ll never do them again.

Frequently Asked Question

⭐What are button mushrooms? Is it ok eating them?

Button mushrooms belong to the kind of champignons which means that they can be used in recipes. 

They look almost the same as their “relatives” do, and grow the same way as champignons do. The only sign that makes them stand out is that their caps have white “flakes” and the caps themselves are bigger (3-8 cm) than champignons usually have. 

⭐I noticed that, when I store mushrooms, they start having dark spots on top of their caps. Does it mean that they’re not suitable for eating? 

The color of the darners’ caps can change indeed and the spots may appear. Dark spots usually grow on top of the caps if we store mushrooms wrongly and they already started going bad. Unfortunately, such a sign means that darners are not safe for eating any more and they must be thrown away. 

The optimal way to prevent these spots from appearing is to check raw fungi regularly while keeping them. Also, ensure that you provide the boletuses with proper conditions. When we store raw mushrooms, they must be dry, placed in the airtight container so that the air couldn’t bring odors to them.

⭐Shall I keep the frying pan open when frying fungi?

No, it’s better not to open the pan since the moisture will evaporate completely leaving the fungi dry.
