5 Simple Steps to Store Mushrooms & Keep Them Fresh for 7 Days
How to Store Mushrooms to Prevent Spoilage & Waste

Mushrooms are a kitchen favourite, prized for their rich, earthy flavour and nutritional benefits. However, their delicate nature means they can spoil rapidly, often becoming slimy or developing dark spots within just a day or two of purchase. This common frustration leads to significant food waste, but it is entirely preventable. The secret lies in understanding their composition and providing the correct storage environment.

Why Proper Mushroom Storage is Crucial

The primary reason mushrooms deteriorate so quickly is their high water content. Fresh mushrooms are composed of nearly 90% water. When this moisture is trapped—typically in sealed plastic packaging—it creates a damp habitat that accelerates decay and microbial growth. Proper storage techniques aim to counteract this by maintaining a cool, dry, and breathable setting. This not only preserves the mushroom's firm texture and distinctive taste but also locks in nutrients, ensuring your dishes like risottos, stir-fries, and soups taste fresh and flavourful, not soggy and dull.

The Right Way to Store Mushrooms in the Refrigerator

For short-term storage, your refrigerator is the best ally. The key is to avoid the original plastic packaging. Instead, transfer your mushrooms to a paper bag or wrap them loosely in a clean, dry kitchen towel. This simple switch allows excess moisture to be absorbed while still letting the mushrooms breathe. Place this package in the crisper or vegetable drawer, where the airflow is ideal. Following this method, most mushroom varieties can stay fresh, firm, and aromatic for five to seven days.

It is critical to handle mushrooms gently. Avoid stacking heavy items on top of them, as pressure can cause bruising and speed up spoilage. If you must use a plastic container, never seal it completely. Leave the lid slightly ajar and place a dry paper towel inside to soak up any condensation.

Essential Don'ts: Washing and Plastic Traps

A major mistake many home cooks make is washing mushrooms before storing them. Never wash mushrooms until you are ready to cook them. Introducing water before storage drastically hastens the spoiling process. Instead, use a soft brush, cloth, or paper towel to gently wipe away any visible dirt or debris. If rinsing is absolutely necessary, do it just before cooking and pat them thoroughly dry immediately.

Long-Term Storage and Salvaging Soft Mushrooms

For keeping mushrooms edible beyond a week, your freezer is the solution. However, you should not freeze them raw. Lightly sauté or blanch your mushrooms first, let them cool completely, and then pack them into labelled, freezer-safe bags or containers. Properly prepared, frozen mushrooms can last for up to two months and are perfect for adding to soups, sauces, and stews.

What should you do with mushrooms that are just beginning to soften or develop mild wrinkles? Do not throw them away yet. These are perfect for immediate cooking. A quick sauté with garlic, butter, or olive oil can revive their texture and concentrate their flavour. This is an excellent way to prevent waste. Only discard mushrooms that have turned slimy or emit a sour, unpleasant odour.

In summary, the art of storing mushrooms hinges on three principles: keep them cool, dry, and ventilated. Shun airtight plastic, handle with care, delay washing, and utilise your freezer for long-term needs. By integrating these straightforward steps into your kitchen routine, you can significantly reduce food waste, save money, and ensure your mushrooms are always ready to elevate your meals with their superb flavour and texture.
