Properly stored, cooked mushrooms will last for 3 to 5 days in the refrigerator.
How long can cooked mushrooms be left at room temperature? Bacteria grow rapidly at temperatures between 40 °F and 140 °F; cooked mushrooms should be discarded if left out for more than 2 hours at room temperature.
To further extend the shelf life of cooked mushrooms, freeze them; freeze in covered airtight containers or heavy-duty freezer bags.

How long do cooked mushrooms last after being frozen and thawed? Cooked mushrooms that have been thawed in the fridge can be kept for an additional 3 to 4 days in the refrigerator before cooking; mushrooms that were thawed in the microwave or in cold water should be eaten immediately.
How to tell if cooked mushrooms are bad? The best way is to smell and look at the mushrooms: discard any that have an off smell or appearance, do not taste first.
