Portobello mushrooms, also known as Agaricus bisporus, are one of the most commonly consumed mushrooms in the world
Portobello mushrooms are a large variety of mushroom, with caps ranging from 10 to 15 centimetres in diameter. They are brown, with a firm, smooth texture, although some may have small flaky scales. They are often grilled, baked, roasted, sautéed, or stuffed, and their meaty texture makes them a popular meat substitute in vegetarian dishes. They can be used as a burger patty or in tacos, fajitas, and enchiladas. They are also used in soups or as a pizza topping.
Portobello mushrooms are widely available in supermarkets and farmers' markets, both fresh and canned, and are sold whole or sliced. They are typically sold with their stems removed, although the entire mushroom is edible. When buying portobello mushrooms, it is best to choose fresh, firm mushrooms with dry, plump gills. They should be stored in their original packaging or a porous paper bag in the refrigerator and consumed as soon as possible, as they spoil quickly.
The name 'Portobello' was likely selected as part of a marketing campaign in the 1980s, and multiple spellings, including Portabella and Portabello, are accepted. The origin of the name is unclear, but some theories suggest it may be derived from Italian words meaning 'handsome' or 'beautiful', or it may be linked to London's famous Portobello Road shopping district.

They have a rich flavour and a dense, meaty texture
Portobello mushrooms, also sometimes called portabella, have a rich, earthy, meaty, and brothy flavour, a combination of flavours known as umami. This umami flavour comes from a type of amino acid called glutamate, which is naturally present in mushrooms, as well as in other foods, such as parmesan cheese and anchovies. Portobello mushrooms have a more intense umami flavour than other mushrooms because, as they mature and lose their water content, the flavours become more concentrated.
Portobello mushrooms are a large variety of mushroom, with caps ranging from 10 to 15 centimetres in diameter. Their caps vary from tan to dark brown and may be smooth or lightly wrinkled, sometimes featuring small flaky scales. They are native to grasslands in Eurasia and North America and are cultivated in more than 70 countries, making them one of the most commonly consumed mushrooms in the world.
The meaty texture of portobello mushrooms comes from the fact that, by the stage at which they reach full size, the caps have opened fully, exposing the gills and accelerating moisture loss, leading to a dense texture. This texture, along with their rich flavour, makes portobello mushrooms a particularly useful meat substitute. They can be sliced into thin strips and used in dishes like tacos, fajitas, and enchiladas, or served whole as steaks or burgers.
Portobello mushrooms are versatile and can be cooked in a variety of ways. They are most commonly grilled, sautéed, or roasted, but can also be baked, stuffed, or cooked under the broiler.
