Finding fresh mushrooms in the market is easy-peasy!  At their best, they are juicy, earthy and add a wonderfully savoury note to any dish. But mushrooms are delicate little creatures and contain a whole lot of moisture, so they can go bad fast.

So, how can you tell whether the fresh mushrooms you're using are actually fresh?

You don’t need to be an expert to know the basics! Fresh mushrooms should feel firm and plump, have a clean appearance and smell pleasantly earthy. Mushrooms that are slimy, excessively wrinkled, very soft or have an unpleasant odour are definitely past their prime.

Why Mushroom Freshness Matters

When it comes to freshness, looks aren't everything! Beyond how good a mushroom looks on a shelf, it is also about their flavour, texture and overall quality.

Taste

Fresh mushrooms have a naturally earthy, savoury flavour that intensifies as it cooks. As they age, their flavour can become more washed down, considering they are 90% water.

Texture

One of the easiest ways to judge is by touch. Fresh mushrooms should feel firm and plump - not soft, rubbery or mushy. Mushrooms naturally lose moisture as they age, which can leave them looking rather shrivelled.

Food Safety

Spoilage and food safety aren't always the same thing. Spoilage organisms can cause noticeable changes such as unpleasant smells, sliminess and changes in texture, while harmful microorganisms may not produce obvious sensory signs. That's why proper refrigeration and careful handling are important even when mushrooms look fine.

8 Signs Fresh Mushrooms are Still Good

1. Firm Texture

Give your mushroom a gentle squeeze. If it’s fresh, you should feel a little resistance when you touch them. But if it’s mushy, soft or rubbery, throw it out!

2. Dry Surface

Fresh mushrooms are clean and dry on the surface. But if they are covered in liquid or slime, it’s better you avoid them. Store your mushrooms in breathable containers to ensure that there’s no excess moisture.

3. Natural Colour

While colours vary from mushroom to mushroom, there are certain things you must look out for, no matter what the variety! Avoid significant, unusual discolouration, extensive dark patches or bits that look damaged or decayed. 

4. Fresh Aroma

A quick sniff before you use them is mandatory! Fresh mushrooms should have a mild, clean, earthy aroma. They shouldn't smell sour, rotten, or unpleasant.

5. Closed Gills (Where Applicable)

Closed gills means the delicate tissue connecting the cap and stem is still intact - this means the mushroom is young and has a more delicate flavour. Open gills can indicate a more mature mushroom and a deeper flavour. While this sign depends on the variety, it’s a good marker to test the freshness of your mushroom.

6. No Slime

This is the most obvious sign, but a slimy coating is one of the clearest signs that your mushrooms have gone bad! Fresh mushrooms should not feel sticky - they should be dry and clean to the touch.

7. No Wrinkles

Fresh mushrooms should look plump and youthful. Wrinkles happen when mushrooms lose moisture. If the cap looks wrinkled or leathery, you’re better off letting them be.

8. Minimal Bruising

Mushrooms bruise easily, so a small mark doesn't mean they are spoiled. However, extensive bruising can be an indicator of low quality. Fresh mushrooms should ideally have smooth, unblemished caps. We handle our mushrooms with care which reduces the chances of blemishes and browning.

Our hat tip to you? When in doubt, it's better to discard them.

How to Store Fresh Mushrooms Properly

The way you store mushrooms can make a major difference! Mushrooms do well with refrigeration. Keep them in their original packaging, or in a porous paper bag - no tightly sealed plastic bags or containers. Clean mushrooms only before you're ready to cook them. If you need to clean them, gently brush away debris or briefly rinse them and pat them dry.

How Long Do Fresh Mushrooms Last?

Shelf life depends on the variety, how recently it was harvested, how it was packaged and how consistently it has been refrigerated. Generally, fresh mushrooms can last around five days to a week in the refrigerator when stored properly, although some varieties may last for less or more time.

Buying Tips at the Grocery Store

Want to bring home the freshest mushrooms? We have a few tips that can help! Choose mushrooms that look plump and clean, with minimal bruising. If a pack has too much moisture, avoid it.
