The term "Italian oyster mushroom" typically refers to the Pleurotus ostreatus species, often simply known as the oyster mushroom. This mushroom has a mild and delicate flavor, which can sometimes be described as slightly sweet with a hint of anise. The texture is tender yet meaty, making it an appealing choice for various culinary applications.

When cooked, Italian oyster mushrooms develop a rich, umami flavor that enhances dishes without overpowering them. They absorb the flavors of sauces and seasonings well, making them a versatile ingredient in Italian cuisine, such as risottos, pasta dishes, and sautéed vegetables. Their ability to complement a wide range of flavors allows them to shine both as a main ingredient and as a supporting component in a dish.
