Fridge Life of Cooked Mushrooms

Cooked mushrooms are generally best used within about 3 to 4 days in the refrigerator. That timeline assumes they were cooled and stored reasonably promptly.

How to Tell Leftovers Are Bad

If cooked mushrooms develop a sour smell, obvious slime, or were left in questionable temperature conditions, it is better to discard them than gamble on leftovers.

When to Freeze Leftovers

If you will not use cooked mushrooms soon, freezing them usually makes more sense than trying to stretch fridge storage beyond a few days.
