Yes, fresh oyster mushrooms can be eaten raw, but their firm texture may be difficult for some people to digest. Cooking softens them and is usually the more enjoyable option, especially for a first taste.
Wipe oyster mushrooms with a damp cloth or rinse them briefly under cool running water. Avoid soaking them, since they absorb moisture; pat them dry before cooking so they brown rather than steam.
Keep oyster mushrooms unwashed in a breathable paper bag in the refrigerator. A sealed plastic container can trap moisture and speed up spoilage; check for a slimy surface, mold, or an unpleasant sour smell before using.
You can freeze oyster mushrooms, but freezing them raw often leaves them softer and less pleasant after thawing. Sauté them first, let them cool, and freeze in an airtight container; use them later in soups, sauces, or other cooked dishes.
Yes, oyster mushroom stems are edible. The stems of larger mushrooms can be tougher than the caps, so trim any woody base and slice the rest thinly for stir-fries, soups, or stock.
Sauté oyster mushrooms in a hot pan with a little oil until their released moisture has evaporated and the edges begin to brown. Cook in batches rather than crowding the pan to avoid a watery, steamed texture.
Oyster mushrooms can turn rubbery when they are undercooked or crowded in a pan, where they steam instead of browning. Give them room in a hot pan and cook until their moisture has evaporated and the texture softens.
Oyster mushrooms have a mild, savory flavor and a tender, slightly chewy texture when cooked. Browning brings out a deeper, meatier taste, and they pair well with garlic, herbs, and soy sauce.
Yes, thinly sliced fresh oyster mushrooms can be added to a salad, but their raw texture is quite firm. A quick sauté followed by cooling gives a softer topping if you prefer not to eat them raw.
Discard oyster mushrooms that have developed mold, a slimy coating, or a strong sour or unpleasant odor. Fresh ones should look reasonably firm and dry; slight drying is different from spoilage, but a wet, deteriorating texture is a warning sign.

Oyster mushrooms grow in overlapping, fan-shaped clusters on wood and are cultivated around the world. Raw oyster mushrooms can be sliced into salads, though they are more commonly cooked, when their texture softens and their savoury flavour becomes more pronounced.
Fresh and raw, they are mildly earthy and pleasantly chewy. Try them thinly sliced with crisp greens, or sauté them for a quick side, topping or addition to soups and grain bowls. They are low in calories and provide fibre and B vitamins; a 100 g portion has 2.3 g of fibre. For a lighter preparation, cook them with a little oil and finish with lemon, herbs or garlic.
High
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
