About Portobello mushroom
A portobello mushroom is a mature form of the cultivated button mushroom, sold with its broad cap intact. It is commonly grilled, roasted, stuffed or sliced for cooking. The cap’s open underside may expose dark gills, and the stem can be retained or removed depending on the preparation.
The cap is broad and brown, with a firm, meaty texture and an earthy, savoury flavour that deepens when cooked. Fresh whole caps and sliced mushrooms are common forms. Size, maturity, moisture loss and whether gills or stem are included can affect both cooking behaviour and measured composition.
