Oyster Mushroom

Oyster mushrooms are one of the most widely cultivated mushrooms in the world, named for their resemblance to an opened oyster shell. They grow in overlapping clusters and range in colour from pale grey to cream, sometimes with hints of pink or yellow depending on the variety.

Their mild, slightly anise-like flavour and tender texture make them versatile in the kitchen. They work well in stir-fries, pasta dishes, soups, and as a meat substitute in vegetarian cooking, where their meaty texture holds up nicely. Unlike some mushrooms, the stems are edible though they can be a little tougher than the caps.

Oyster mushrooms have become increasingly popular in Australian cooking as they’ve become more widely available in supermarkets and farmers’ markets. They’re a good entry point for anyone looking to cook with more interesting mushroom varieties beyond the standard button or flat mushroom.

How it's made

Oyster mushrooms are commercially farmed by inoculating a growing medium — typically pasteurised straw, sawdust, or agricultural waste — with mushroom spawn. The substrate is packed into bags or containers and kept in controlled growing rooms with carefully managed temperature, humidity, and airflow. The fruiting bodies emerge in clusters from openings in the bags within a few weeks and are harvested by hand, usually producing several flushes from the same substrate.
