About Agaricus bisporus

Agaricus bisporus is the cultivated mushroom sold in familiar white button, brown cremini, and mature portobello forms. The young mushrooms are commonly eaten raw or cooked; cooking methods include sautéing, roasting, grilling, and adding them to soups or sauces. The forms reflect differences in maturity and appearance within this mushroom species.

The cap and stem are fleshy and mild, with an earthy, savoury flavour that deepens when cooked. Button mushrooms are small and pale, while brown forms have darker caps; mature portobellos have broad, open caps. Fresh and preserved products are also sold, but are not interchangeable in texture.
