Store fresh mushrooms in a paper bag in the fridge, which absorbs excess moisture and lets them breathe, keeping them fresh for about a week. Avoid sealed plastic, which traps moisture and makes them slimy. Keep mushrooms whole and unwashed until you are ready to use them.
Mushrooms: paper bag in the fridge, not plastic. Keep them dry and unwashed until use. They last about a week.
How to Store Them
- Keep mushrooms in a paper bag, which absorbs moisture and lets them breathe.
- Avoid sealed plastic bags or containers, which trap moisture and cause sliminess.
- Store them whole and unwashed; wash only just before cooking.
- Keep them in the main fridge, not the crisper, if it gets too humid.
Why Moisture Is the Enemy
Mushrooms are mostly water and spoil quickly when they get damp, turning slimy and dark. A paper bag wicks away excess moisture. Wash them right before use, since washing early speeds spoilage. To keep them longer, cook and freeze them; see can you freeze mushrooms. A breathable container works if lined with paper.
