Agaricus bisporus

The older brother of the chestnut mushroom is often stuffed, but also great baked, fried in slices or on the BBQ.


The Portobello is the largest version of the chestnut mushroom. Just like the white mushroom, the cap of the chestnut mushroom springs open when it reaches a certain height. The average Portobello  has a diameter of 100 mm and weighs approx. 95 g. Portobellos have a fuller, more distinct flavour. Because they contain more dry matter than ‘flat’ mushrooms, more mushroom is left over after cooking. Portobellos are more resistant to temperature changes than white flat mushrooms and that’s why they have a longer shelf-life.
