Cooked shiitake mushrooms can still be eaten overnight, but the nutrition and flavor will be a little worse.

Generally speaking, shiitake mushrooms can be stir-fried and stewed. Whether it is stir-fried or stewed, if you do not have finished mushrooms, you should put them in the refrigerator to save.

Placed in the refrigerator's preservation room, it can delay the deterioration of mushrooms; in a low temperature environment, even if the mushrooms have been cooked, placed in the night, there is still no big problem.

Yesterday's mushrooms can be eaten hot at dinner the next day; however, you should try to heat the remaining mushrooms as much as possible during this process.

Storage of Shiitake Mushrooms

Shrooms that are uncooked are generally able to be stored for a longer period of time, provided they are dry enough and kept in a fresh room.

Such mushrooms can usually be protected for about 7 days, so overnight storage will not affect the quality of the mushrooms, and we can eat them with confidence.

But as shiitake mushrooms are left for a longer period of time, the corresponding flavor and nutrition of shiitake mushrooms will be lost. If the refrigerator is humid, there is also the possibility of mold.

It is advisable not to buy too many shiitake mushrooms at once. After all, shiitake mushrooms are in good supply now, so just buy them when you need to eat them.
