Oyster mushrooms are a versatile ingredient that can be used in soups or roasted in an oven. They are relatively sensitive, so it is important to know how to clean and store them to maintain their texture and flavor. When cleaning oyster mushrooms, some sources suggest using a brush or rinsing them under cold water to remove any dirt, while others recommend using a sharp knife to carefully cut around the central stem to separate the individual caps. To store oyster mushrooms, they can be refrigerated in a paper bag for up to a week or frozen after being sautéed in butter or olive oil.
How to Wash Oyster Mushrooms
| Characteristics | Values |
|---|---|
| Washing with water | Some sources advise against washing mushrooms with water as they will absorb liquid and become difficult to cook. Others argue that the amount of water absorbed is negligible and that washing removes dirt and bugs. |
| Brushing | Some recommend using a brush to remove dirt from the surface of the mushrooms to avoid getting them wet. |
| Rinsing | If you do rinse oyster mushrooms, it is recommended to rinse before slicing them. Rinse under cold running water and then spin them dry in a salad spinner. |
| Refrigerating | To store oyster mushrooms for up to a week, place whole, unwashed mushrooms in a paper bag in the refrigerator. The bag will absorb excess moisture. |
| Freezing | Separate the mushrooms from the central stem using a sharp knife, then sauté them in butter or olive oil until they release their moisture. Let them cool, then seal tightly in a plastic bag and freeze. |
| Removing gills | Oyster mushrooms have dark black gills that can be eaten, but they will turn your food a murky brown. It is recommended to scrape them out with the tip of a spoon. |
| Removing stems | Oyster mushrooms come bundled with individual caps attached to a central stem. Use a sharp knife to cut around the firm central stem to separate the caps. The stem can be discarded or added to stock. |

What You'll Learn
Rinse under cold water
Rinsing oyster mushrooms under cold water is a simple and effective way to clean them. Firstly, ensure the mushrooms are whole and uncut, as cut mushrooms will absorb water and become slimy. Next, place the mushrooms under a cold tap and gently rinse them, ensuring that any dirt or soil is washed away. You can use your fingers to gently rub the mushrooms as they are rinsed, helping to dislodge any stubborn dirt. Be careful not to be too rough, as oyster mushrooms are relatively delicate.
After rinsing, dry the mushrooms as best you can with a clean cloth or kitchen paper. You can also use a salad spinner to remove excess water, which is an effective way to ensure the mushrooms are dry and prevents them from becoming slimy. It is important to note that mushrooms should only be rinsed when you are ready to cook them, as they will deteriorate quickly if left wet.
Washing mushrooms under cold water is a quick and easy method, and while some sources suggest that mushrooms should only be brushed clean, it is generally accepted that rinsing mushrooms will not significantly affect their texture or cooking properties. In fact, rinsing mushrooms can help to remove any unwanted bacteria or dirt, which may be present even on "clean" mushrooms.
It is worth noting that oyster mushrooms are relatively sensitive and perishable, so they should be stored correctly and used within a few days of purchase to maintain their texture and flavour. However, rinsing under cold water is a simple and effective way to clean oyster mushrooms, ensuring they are free from dirt and any other unwanted substances.

Use a brush
Oyster mushrooms are a delicious treat and can be found nearly year-round. They are also extremely perishable, so it's important to clean and store them properly.
Before cleaning, assess your oyster mushrooms. They should not be slimy, have brown or decaying spots, or feel moist or powdery. If you notice any of these signs, trim or cut off the undesirable parts and discard them.
Now, to the cleaning! If your oyster mushrooms are lightly soiled, you can simply brush them off with a dry paper towel or cloth. You can also use a mushroom brush, which is a specialty tool with soft bristles perfect for cleaning delicate mushrooms. Brush each mushroom on all sides to remove loose dirt.
If your oyster mushrooms are heavily soiled, you may need to take an extra step before brushing. You can dip and swish them in clean water, checking for any remaining dirt, bugs, or spores. Beetles particularly like to hide in the gills of oyster mushrooms, so be sure to run your finger across the gills to check for any unwanted guests.
After brushing, give your oyster mushrooms a quick rinse in a colander under cool running water if you plan to cook them right away. Shake the colander to drain the excess water, and then use a salad spinner to spin the mushrooms dry.
And that's it! Your oyster mushrooms are now clean and ready for cooking or storage.

Dry in a salad spinner
Oyster mushrooms are relatively clean as they grow on substrates like wood, cardboard, or coffee grounds, so they require little cleaning before cooking. You can simply wipe them gently with a paper towel or a clean, damp cloth. If you prefer to wash your oyster mushrooms, a quick rinse under running water will do the trick, and then leave them to dry on a clean towel.
If you want to be extra thorough, you can use a salad spinner to dry your mushrooms. First, place the mushrooms in the basket of the salad spinner and rinse them with running water until you have removed all debris. Then, place the basket back into the spinner and spin it to remove excess water. Make sure to wash your spinner afterward.
Salad spinners are a great way to remove excess moisture from mushrooms, especially from the frills of oyster mushrooms. They are also useful if you are short on time, as they dry mushrooms much faster than air-drying on a towel. Additionally, using a salad spinner can help cut down on paper waste if you would otherwise be blotting the mushrooms with paper towels.
It is important to dry mushrooms thoroughly before cooking, as mushrooms are like sponges and will soak up water if left sitting in it. Exposure to excess moisture can speed up rotting, so it is best to wash mushrooms right before cooking them.

Remove the gills
Oyster mushrooms are a delicious treat, but they often come with unwanted guests—bugs and beetles! These critters like to get deep down in the gills, so it's important to clean your mushrooms thoroughly before cooking or eating them. Here are some tips to effectively remove the gills from oyster mushrooms:
Inspect the Mushrooms: Before you start, carefully examine the oyster mushrooms. Look for any dirt, insects, or other contaminants that may be hiding in the gills. Oyster mushrooms are known for their decurrent gills, which means the gills are attached to and run down the stem. Most oyster mushrooms don't have a stem, but if they do, it's usually short and stubby.
Brush Off Lightly Soiled Mushrooms: If your mushrooms are only lightly soiled, you can use a dry paper towel or a clean, slightly damp cloth to gently brush or wipe off any loose dirt or debris. This is often sufficient for cleaning oyster mushrooms, as they are relatively clean and don't usually have excessive dirt.
Rinse Under Running Water: If your mushrooms are particularly dirty or buggy, you may need to rinse them under cool running water. Place the mushrooms in a colander or strainer and gently shake them to remove excess water. Pay close attention to the gills to ensure that all dirt and insects are washed away.
Use a Knife to Scrape: For any stubborn dirt or debris that's stuck on the gills, carefully use the edge of a small, sharp knife to gently scrape it off. Hold the mushroom in one hand and carefully scrape with the knife in your other hand. Be cautious not to cut yourself or damage the mushroom excessively.
Dry the Mushrooms: After rinsing, it's important to dry the mushrooms thoroughly. You can use paper towels or a dry towel to gently press down on the mushrooms and absorb excess water. Alternatively, if you have a salad spinner, you can use it to spin the mushrooms dry. Make sure the mushrooms are fairly dry before cooking or storing them.
Trim and Cut: While not directly related to gill removal, it's worth mentioning that you should trim any parts of the oyster mushrooms that look wet, dirty, or moist. Additionally, trim off the bottoms of the stems (roots) as they can be tough and difficult to cook.
Remember, oyster mushrooms are versatile and can be used in various recipes, including stir-fries, roasting, sautéing, soups, and stews. Always cook and enjoy your mushrooms safely!

Separate from the central stem
Oyster mushrooms are a delicious addition to soups and stir-fries, but they do require some preparation before cooking. To separate oyster mushrooms from their central stem, start by taking a sharp knife. Carefully cut around the firm central stem with the knife, gently working your way around it. You will see the individual mushroom caps start to separate and fall away from the stem. You can discard the stem, or keep it to add flavour to stocks and soups.
This method of cutting away the caps is a precise way of preparing oyster mushrooms, and it also helps to clean them. Oyster mushrooms often come in a large group, all attached to this central stem. By cutting them away, you can ensure each mushroom is cleaned individually. It is important to clean mushrooms before cooking, as they can carry dirt or even tiny bugs.
Some cooks prefer to avoid washing mushrooms with water, believing it negatively affects their texture. Instead, they recommend using a brush to remove any dirt. However, others argue that mushrooms are largely water, and a small amount of water from washing will not significantly impact the cooking process. If you do choose to wash your mushrooms, it is best to do so just before cooking, as mushrooms can turn slimy if left too long after washing.
If you are planning to freeze your oyster mushrooms, you will also need to separate them from the central stem. Again, use a sharp knife to carefully cut the mushrooms away from the stem. From there, you can sauté them in butter or olive oil until they release their moisture. Once cooked, let them cool before sealing them in a plastic bag and placing them in the freezer. Frozen oyster mushrooms are a great addition to stews and stir-fries, as they heat up quickly straight from the freezer.
