Oyster Mushroom

What Are Oyster Mushrooms?

The oyster mushroom (Pleurotus ostreatus) is a woodland mushroom named for its fan-shaped gray-brown cap, which resembles an oyster shell. It grows in clusters on dead or weakened tree trunks in the wild and is also among the easiest mushrooms to cultivate.

Compared with button mushrooms, it has a meatier, more fibrous texture and a mildly sweet, anise-like aroma. These qualities make it popular in meat-alternative recipes.
