Generally speaking, fresh, whole mushrooms will last between 7 to 10 days in the fridge. Sliced mushrooms, because they’re more exposed, are more like 3 to 5 days. But here’s the secret: storage is everything. You’re not just guessing—you’re orchestrating a mini climate.
Step One: Ditch the Plastic (Seriously!)
That clamshell or plastic bag is a steamy prison for mushrooms. They breathe, you know! Transfer them to a paper bag or wrap them loosely in a dry paper towel inside a bowl. This lets moisture escape, so they stay firm and happy, not slimy and sad. Think of it as giving them a tiny, breathable penthouse.
Step Two: The Washing Wisdom (Wait for It)
Here’s a game-changer: never wash mushrooms until you’re ready to cook them. Excess water is their arch-nemesis. Just give them a gentle brush with a dry cloth or mushroom brush before storing. Trust me—your future sautéed self will thank you.
