Oyster mushrooms have a subtle seafood flavour with hints of anise and a faint, earthy taste. However, some people have described the smell of oyster mushrooms as fishy. This may be due to the extra moisture that is sometimes present in wild mushrooms. Despite this, oyster mushrooms are a versatile ingredient that can be used in soups, stir-fries, stews, sauces, and more.

What You'll Learn
Oyster mushrooms have a subtle seafood flavour
Oyster mushrooms (Pleurotus ostreatus) are edible fungi that are commercially popular worldwide. Their name is derived from the shape and colour of their caps, which resemble oysters. The caps vary in colour from white-grey to light brown to dark brown, while the flesh and gills range from white to cream and are firm in texture. Oyster mushrooms are one of the few carnivorous mushrooms, as they consume bacteria and tiny worms in addition to rotting wood.
Oyster mushrooms are often described as having a subtle seafood flavour. Their taste has also been likened to anise, with a faint, earthy undertone. When cooked, oyster mushrooms develop a soft, meaty texture that complements soups, stir-fries, and salads. They are a good source of protein and are high in fibre and vitamin B.
While the mushrooms themselves have a subtle flavour, their aroma can be more pronounced. Some people associate the smell of fresh oyster mushrooms with the sea, describing it as fishy or reminiscent of the seashore. However, others disagree with this characterisation, finding it difficult to pinpoint a specific scent. The noted mycologist Tom Volk describes the smell as "very mild to very strong, sometimes sweet with the smell of anise (licorice)".
The perception of oyster mushrooms' aroma may be influenced by their moisture content. Some people have observed that wild or foraged oyster mushrooms tend to have a stronger smell, which could be due to the extra moisture absorbed from the rain. Additionally, the method of preparation can affect their fragrance. For example, cooking oyster mushrooms reportedly diminishes their fishy aroma.
In terms of culinary applications, oyster mushrooms are incredibly versatile. They can be added to stews, soups, stir-fries, sauces, or used as a pizza topping. Their subtle taste makes them a great side dish, and they can be cooked in butter or olive oil with garlic, pepper, and spices like thyme. To preserve their velvety texture, it is important to prevent them from absorbing excess moisture during cooking and to avoid overcooking them.

Oyster mushrooms are one of the few carnivorous mushrooms
Oyster mushrooms, or Pleurotus ostreatus, are one of the few types of carnivorous mushrooms. They are edible fungi that derive their name from the shape and colour of their caps, which resemble oysters. The caps vary in colour from white-grey to light brown to dark brown, while the flesh and gills range from white to cream and have a firm texture. Oyster mushrooms typically grow in the wild in temperate forests and thrive in warm weather with high humidity. They are one of the most popular mushrooms in the world due to their delicate, subtle flavour and velvety texture. They are commonly added to soups, stir-fries, stews, and sauces, or used as a pizza topping.
Oyster mushrooms are unique among mushrooms in that they consume bacteria and nematodes, or roundworms, in addition to rotting wood. Nematodes are tiny worms that are among the most abundant animals in the soil. Oyster mushrooms have evolved to produce a deadly nerve agent or toxin that causes paralysis in nematodes within minutes of contact. The toxin is believed to target a crucial part of the worms' nervous system, as nematodes separated by millions of years of evolution are all susceptible to it. Once the nematodes are paralysed, the oyster mushrooms inject their filaments into the corpses, dissolve the contents, and absorb the resulting slurry to meet their nitrogen needs.
The carnivorous nature of oyster mushrooms has sparked interest in using them to control nematodes that attack crop plants. While their meat-eating habits may be surprising, it is important to note that oyster mushrooms are still considered vegan because they do not consume other animals' muscle tissue. In fact, their ability to derive nitrogen from nematodes makes them an excellent source of protein for human consumption.
The subtle flavour of oyster mushrooms has hints of seafood and anise, with a faint, earthy taste. This subtle taste makes them a versatile ingredient in various dishes. However, some people have reported that foraged oyster mushrooms can have a strong fishy smell, which disappears when they are cooked. This fishy odour may be due to the extra moisture present during foraging, as wild mushrooms tend to have a stronger smell than store-bought ones.
