Button mushrooms are the immature form of Agaricus bisporus
Button mushrooms, also called white mushrooms or white button mushrooms, are the immature form of Agaricus bisporus. They are the most popular mushroom variety, constituting 90% of mushrooms consumed in the United States. They are also the least expensive and have the mildest flavour, although they readily absorb the flavours of other ingredients when cooked.
Button mushrooms are native to grasslands in Eurasia and North America and are cultivated in over 70 countries, making them one of the most commonly and widely consumed mushrooms globally. They are white in colour and measure 1 to 3 inches across. Their flesh is delicate, and they should be handled gently as they bruise easily. When bruised, the white flesh first turns pink and then brown.
Button mushrooms have a high water content, typically around 92%, which contributes to their mild flavour and longer cooking time compared to more mature varieties. They are versatile in cooking and can be eaten raw or cooked through various methods such as sautéing, stir-frying, grilling, braising, and roasting.
Button mushrooms are the least mature form of Agaricus bisporus, followed by cremini mushrooms, which are slightly brown, and then portobello mushrooms, which are the largest, darkest, and most mature stage of the species. All of these mushrooms are the same but at different stages of maturity.

When bruised, the white flesh first turns pink and then brown.
The mild flavour of button mushrooms allows them to readily absorb the flavours of other ingredients in a dish. They have an earthy, meaty, and brothy taste, 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 and other foods such as parmesan cheese and anchovies. The high water content of button mushrooms, around 92%, dilutes the umami flavour, making it less powerful compared to other mushrooms.
The versatility of button mushrooms extends beyond their flavour. They are easy to slice and can be added to various dishes, including pasta, stir-fries, omelettes, salads, soups, sauces, pizzas, burgers, and side dishes. When selecting button mushrooms at the grocery store, look for those that are firm, have a smooth appearance, and a dry but not dried-out surface. They typically feature a closed veil under the mushroom cap.

Agaricus bisporus is native to grasslands in Eurasia and North America. It was first scientifically described for commercial cultivation by French botanist Joseph Pitton de Tournefort in 1707. French agriculturist Olivier de Serres also noted that transplanting mushroom mycelia would lead to more mushroom growth. The white button mushroom variety was discovered in 1925 at the Keystone Mushroom Farm in Coatesville, Pennsylvania, by owner and mycologist Louis Ferdinand Lambert. Lambert brought the white mushroom back to his laboratory, and it was cultivated and distributed for its attractive appearance, similar to the commercial development of the navel orange and Red Delicious apple.
Button mushrooms are versatile in cooking and can be eaten raw or cooked via sautéing, stir-frying, grilling, braising, and roasting. They are commonly used in recipes such as tarts, omelets, pasta, risotto, and pizza. They have a high water content, around 92%, and a mild umami flavour due to the presence of glutamate. They are delicate and should be handled gently to avoid bruising, which causes the white flesh to turn pink and then brown.
