The exact answer to the question regarding how long can cooked mushrooms last depends to a large extent on the conditions of storage after cooking. As the temperature inside and outside the fridge differs and so does the speed of bacterial growth, where the cooked mushrooms were stored assumes huge importance.

After cooking, mushrooms might become soft and mushy, and if not stored properly it might quickly go bad as it is susceptible to spoilage. Thus, properly storing cooked mushrooms in an airtight container could help in keeping cooked mushrooms fresh and safe for consumption for the maximum duration possible.

It is extremely important to discard the cooked mushrooms which have gone bad or have been stored for a longer duration than the optimal period. Consuming such spoiled mushrooms can be detrimental to one’s health as it might lead to food poisoning.


Mushrooms are a versatile addition to any dish as they taste delicious. However, after cooking, mushrooms do not last for long and hence must be immediately consumed. At normal temperatures, cooked mushrooms can last for a few hours. However, if kept inside a refrigerator, they can last for a few days.
