Oyster mushrooms are a popular ingredient in dishes such as soups, ramen, pizza, and more. They are known for their appetizing texture and savory flavor. When it comes to chopping oyster mushrooms, it is recommended to avoid using water to clean them. Instead, simply wipe off any dirt with a damp paper towel or a special brush. The next step is to trim off any tough or woody stems with a sharp knife. Finally, cut, tear, or shred the mushrooms into evenly sized pieces as required by your recipe. Some people also choose to peel oyster mushrooms, but this is not necessary as the skin is safe to eat and will not affect the taste of your dish.

Cleaning oyster mushrooms
Oyster mushrooms are usually sold in large clusters, all attached to the same central stem. When cleaning oyster mushrooms, it's best to avoid washing them under water, as they tend to absorb liquid, which can make them difficult to cook.
- Use a paper towel: If your mushrooms have a lot of heavy residue, wipe off the dirt with a damp paper towel or a damp cloth. Be careful not to use too much water or apply too much pressure, as you don't want to damage the mushrooms.
- Try a quick rinse: If necessary, place the mushrooms in a colander and give them a brief rinse under running water. This is better than submerging them in water, as they won't absorb as much liquid.
- Brush them off: Use a mushroom brush or a pastry brush to lightly brush off any excess dirt. Oyster mushrooms are relatively sensitive, so this method helps to maintain their texture and flavour.
If you plan to use your oyster mushrooms within a week, it's best to store them whole and unwashed in a paper bag in the refrigerator. The bag will absorb excess moisture, keeping the mushrooms firm and meaty.
Before using your mushrooms, always check that they are still good. Look for firm caps and stems, avoiding any that are shrivelled, soft, or slimy. Also, check the gill structure—it should be dry and firm, without any dark or wet spots.

Trimming the stems
Oyster mushrooms are known for their short, almost non-existent stems and wide, fan-shaped caps. When preparing oyster mushrooms, it is important to trim off any tough or woody stems with a sharp knife. This will ensure that the mushrooms are easier to cook and have a more appealing texture.
To begin trimming the stems, use a sharp knife to carefully cut around the central stem. The individual caps will then fall away, leaving you with just the stems. You can discard the stems or reserve them for adding to stock. It is important to note that the stems of oyster mushrooms can be tough and woody, so they may not be suitable for all recipes.
When trimming the stems, it is important to work slowly and gently to avoid removing too much of the inner cap material. The goal is to remove the stem while retaining as much of the cap as possible. Once the stems have been removed, you can further break down the oyster mushrooms by slicing or tearing them into evenly sized pieces as needed for your recipe.
It is worth noting that oyster mushrooms are typically clean and require minimal preparation. Unlike other varieties of mushrooms, they rarely need to be peeled. Simply wipe off any dirt or debris with a damp paper towel before trimming and cutting. This will ensure that your mushrooms are ready for cooking without affecting their structure or flavour.

Cutting, tearing, or shredding
Oyster mushrooms are usually sold bundled in a large group, all attached to the same central stem. Before cutting, tearing, or shredding, it is important to clean the oyster mushrooms. Do not use water to clean them; simply wipe off the dirt with a damp paper towel or a special brush to remove any dirt or debris. Oyster mushrooms are almost never dirty since they grow on wood.
Once cleaned, trim off any tough or woody stems with a sharp knife. Cut the end of the stem and you are good to go. The stems are edible but can be woody and fibrous and are usually discarded or used to flavour stock. The number one rule for trimming is to only do it when necessary.
After trimming, cut, tear, or shred the oyster mushrooms into evenly sized pieces as required by the recipe. You can slice them into thick pieces or pull them apart into pieces of your desired size. If you are using them as a garnish or a focal piece on the plate, you can cut off the "root" end, and they will fall apart. Then, slice each petal to roughly the same size. These cut sides sauté beautifully, so get them cut-side down first in the pan to get a good crust. If the mushrooms are for stuffing or are hidden in the dish, chop them up indiscriminately until they are the right size.
Cut oyster mushrooms are best used fresh but can be stored in the refrigerator for 1 to 2 days. They will go bad more quickly after being cut than if they are left whole. You can also freeze mushrooms for later use.

Sautéing
Preparation
Before you start cooking, you need to prepare the oyster mushrooms. Wash the mushrooms with a damp paper towel, kitchen towel, or mushroom brush to remove any dirt, insects, straw, or wood debris. You can also trim the tough central stem that connects the mushrooms together. This part is edible but can be woody and fibrous, so you may prefer to cut it off and save it for vegetable or mushroom stock.
Chopping
Once the mushrooms are cleaned, you can chop them into bite-sized pieces. You can slice or chop them into your desired size and thickness. Leaving the mushrooms whole will give you a meatier texture, while cutting them into smaller pieces will make them more crispy.
Cooking
To cook the mushrooms, heat a large non-stick pan over medium-high heat and add oil or butter. Spread the mushrooms out in a single layer and cook without stirring for 3 minutes. Then, lightly salt the mushrooms and turn the heat down to medium-low. Continue to sauté for about 5 minutes, stirring occasionally, until the mushrooms are golden brown and crisp.
Serving
Oyster mushrooms are now ready to serve. You can adjust the seasoning with salt and pepper, and garnish with fresh parsley and a squeeze of lemon juice. They can be served as a side dish or main course, and go well with pasta, garlic bread, or meat.
Storing Leftovers
Leftover sautéed oyster mushrooms can be stored in an airtight container in the refrigerator for up to 5 days.

Storing
Oyster mushrooms are highly perishable, so it is imperative to buy the freshest ones you can find and store them correctly to maintain their freshness and flavour. Here are some tips on storing oyster mushrooms:
Refrigeration
Oyster mushrooms should be refrigerated promptly. As soon as you bring them home, transfer them to a paper bag or a loosely closed container lined with a paper towel in the refrigerator. Make sure they don't touch impermeable surfaces. Paper bags and paper towels can absorb the moisture released by mushrooms during long-term storage, preventing them from going bad. Cover the mushrooms that remain with plastic wrap lightly and punch in a few holes. They will last for a while longer.
Avoid Plastic Bags
Avoid using plastic bags or containers as they trap moisture, leading to a shorter shelf life. The plastic makes them go slimy. Brown paper bags, on the other hand, make them dry out.
Handle with Care
Mushrooms are delicate, so handle them gently to avoid bruising or damaging their structure. Avoid washing them until you are ready to cook them as excess moisture will speed up spoilage.
Consume Promptly
For the best flavour and texture, try to use oyster mushrooms within a few days of purchase. They will last for about two weeks in good condition but are then prone to becoming slimy, wrinkly, and unappetizing.
Freezing
Freezing is a great option if you want your oyster mushrooms to last for about a month. However, freezing most mushrooms fresh is not recommended as the structure of the mycelium will be compromised, and when thawed, they will be a mess of juice and slimy mushroom parts.
Drying
Drying is a simple and effective way to preserve oyster mushrooms for longer. You can dry them on racks on the counter for several days, in a dehydrator, or in a very low oven on kitchen paper. Once dried, oyster mushrooms can be rehydrated and used, but they may not regain their original texture.

Frequently asked questions
Oyster mushrooms rarely need cleaning as they grow on wood. If they are dirty, wipe them with a damp paper towel or use a brush to remove dirt and debris. Do not wash them with water as they will absorb the liquid and become difficult to cook.

Oyster mushrooms come bundled in a large group, all attached to the same central stem. To remove the stems, use the tip of a sharp knife to carefully cut around the central stem, and the individual caps will fall away.
No, peeling oyster mushrooms is unnecessary. The "skin" or outermost part is safe to eat and has the same taste and texture as the inner flesh. Peeling will only contribute to food waste and take up time.
