Mushrooms are a great ingredient to add to a variety of dishes, but they can be tricky to store. They have a high water content and act like a sponge, which makes them prone to spoilage. When stored in the refrigerator, mushrooms typically last for about a week. However, some sources suggest that they can last for up to two weeks if stored properly. After this period, they may develop dark spots, become slimy or mushy, or emit a strong odour, indicating that they have gone bad and should be discarded. To extend their freshness, it is recommended to store mushrooms in paper bags or unsealed containers in the refrigerator to allow for air circulation and prevent moisture buildup.

Mushrooms can be stored in a paper bag in the fridge to avoid slime
Mushrooms are a versatile staple in any kitchen, adding an earthy, umami flavour to salads, stir-fries, sauces, and other recipes. However, their high water content and ability to act like a sponge make them a challenge to store. If stored incorrectly, mushrooms can turn into a soggy, slimy mess.
To avoid slime, mushrooms should be kept dry. One effective method is to store mushrooms in a paper bag in the fridge. Paper bags allow for air circulation, which is necessary to extend the mushrooms' freshness. When mushrooms are trapped inside a sealed container, they become slimy and decay more quickly. The paper bag will absorb any moisture, keeping your mushrooms safe to eat. For slightly better results, line the paper bag with a paper towel to further cut down on extra moisture.
It is also important to avoid washing mushrooms before storing them, as this can extend their shelf life. Additionally, do not store mushrooms in the crisper drawer of your fridge, as the high humidity will expedite spoilage. Instead, keep them on a shelf in the refrigerator.
If you are storing sliced mushrooms, it is recommended to use an airtight container in the refrigerator. However, avoid using sealed containers for whole, raw mushrooms, as the lack of airflow will speed up spoilage.

Raw mushrooms can last up to two weeks in the fridge
It is also important to note that mushrooms should be stored on refrigerator shelves, as the high humidity of the crisper drawer can cause them to spoil faster. Additionally, bigger mushrooms tend to have a longer shelf life, and whole mushrooms last longer than sliced ones.
It is also important to inspect mushrooms for signs of spoilage before consuming them. In addition to sliminess, other signs that mushrooms have gone bad include a pungent odour, dark spots on the surface, and a soft, mushy, or shrivelled texture. If any of these signs are present, it is best to discard the mushrooms, as consuming spoiled mushrooms can lead to foodborne illness.
While raw mushrooms can last up to two weeks in the fridge, cooked mushrooms have a shorter shelf life of about three to four days. This is because cooked mushrooms are more susceptible to bacterial growth, which can cause them to spoil faster. Therefore, it is important to consume cooked mushrooms within a few days to ensure optimal quality and food safety.

Cooked mushrooms last three to four days in the fridge
Cooked mushrooms can be stored in the fridge for three to four days. They should be stored in an airtight container to maximise their lifespan. Bacteria can grow on cooked mushrooms left in the fridge, causing them to smell and taste bad. To prevent this, you can freeze cooked mushrooms, which will last indefinitely in the freezer. However, they are best eaten within 10 to 12 months for optimal quality.
To prepare mushrooms for freezing, it is recommended to steam or saute them. To steam mushrooms, place a steamer basket in a lidded pot of water and bring it to a boil. Add the mushrooms, cover, and steam for three to five minutes. Then, transfer the mushrooms to an ice bath to stop the cooking process, dry them, and transfer them to a tray. Freeze the mushrooms in a single layer, then transfer them to a freezer-safe container and return them to the freezer.
To saute mushrooms, cut them into equal-sized pieces and cook them in a pan with neutral oil over medium heat for five to seven minutes. Transfer the cooked mushrooms to a tray and freeze them for an hour. This will prevent them from sticking together. Then, transfer the frozen mushrooms to an airtight freezer-safe container and return them to the freezer.
It is important to note that raw mushrooms should not be washed with water, as they have a sponge-like quality and high water content, which can cause them to become mushy. Instead, wipe them clean with a dry paper towel or dish towel before storing. When storing raw mushrooms, it is best to use paper bags or unsealed plastic bags and bowls, as they allow for air circulation, which is necessary to extend their freshness.

Freezing mushrooms is an option to extend their shelf life
Mushrooms have a high water content, which makes them great to cook with and eat, but it also means they can be tricky to store. Fresh mushrooms are best kept in the fridge, in a paper bag, and will last around one week before they start to turn soft, brown, or slimy.
If you would prefer to freeze raw mushrooms, they should be sliced evenly and placed on a baking tray to flash-freeze before being transferred to freezer bags. Raw mushrooms will last around six months in the freezer and can be used without defrosting. They are best suited to dishes where they will be cooked, such as soups, pastas, or stews.
Freezing is a good way to reduce food waste if you have bought too many mushrooms to use at once, but it is worth bearing in mind that the quality of the mushrooms may be affected by the freezing process.

Signs of bad mushrooms include slime, dark spots, and a pungent odour
Mushrooms are a great ingredient to add to your meals, but they can be a pain to store due to their high water content and ability to act like a sponge. They have a short shelf life and are perishable, so it's important to know the signs of bad mushrooms to avoid food poisoning.
One of the most common signs of bad mushrooms is slime. Mushrooms become slimy when they are left in the refrigerator too long or are stored incorrectly. Slimy mushrooms have lost their flavour and nutritional value, and there is a higher chance of bacterial growth on their surface. If slime is the only sign of spoilage, you might still be able to salvage your mushrooms by cooking them in soups, sauces, or chillies.
Dark spots are another indication that mushrooms have gone bad. Mushrooms develop dark spots when exposed to air for too long and begin to oxidize and discolour. If the spots are minor, the mushrooms are likely still edible but won't last much longer. Mushrooms completely covered in dark spots are too far gone and are not safe to eat.
Mushrooms can also develop a pungent or foul odour when they go bad. A strong smell can indicate spoilage, and these mushrooms should be discarded. Cooked mushrooms, in particular, can develop bacteria that cause them to smell and taste bad, so they should be consumed within three to four days.
In addition to these signs, you should also look out for soft, soggy, or mushy mushrooms. Fresh mushrooms should be dry, firm, and smooth with a mildly earthy smell. If your mushrooms exhibit any of these signs of spoilage, it's best to discard them as bad mushrooms can make you sick.
