Portabella Mushrooms

Monterey Mushrooms® Portabella mushrooms are the biggest, boldest mushroom we grow.

King of the Grill— and Beyond

Many sauté White or Baby Bella mushrooms to enjoy over steak, but not everyone gives the mighty Portabella the attention it deserves. As the largest mushroom available in most grocery stores — with caps ranging in size from three inches to six inches in diameter — these big mushrooms pack quite a punch.

Because Portabellas are really only mature Baby Bellas (about three days older and grown on a bed that has been thinned to allow the mushrooms to gain size), these giants taste a lot like their smaller mushroom counterparts, only more robust. While, compared to Whites, Ports have a longer fridge-life and a stronger umami flavor.

They’re also a grill favorite! Because Portabella mushrooms grow larger than Baby Bella, they lose some moisture. This gives them a thicker, more meat-like texture and deeper taste. It’s also why Portabellas are often cut into long slices and served as “steaks” — or served whole in place of a meat patty, kissed between two buns.

Monterey Mushrooms is well known for popularizing the Portabella, arguably the tastiest of all fungi — and we’re proud to sell them at partaking retailers across the nation.

How They Stack Up

Selenium

Portabella mushrooms contain selenium, an antioxidant to help protect body cells from damage that may lead to heart disease, some cancers, and other diseases of aging. Additionally, selenium has been found to be important for the immune system and for fertility in men.

Sodium

All mushroom varieties are low in sodium, but Portabellas are a close runner next to Baby Bellas for containing the lowest sodium content. Because of their umami properties, Brown mushrooms help those watching their salt intake reduce their daily consumption— all while enjoying a meat-like flavor. 

Potassium

Portabellas also contain their fair share of potassium, which plays an important role in helping your body maintain fluid and electrolyte balance.

B Vitamins

Portabellas boast a few B Vitamins, including Riboflavin, Niacin, and Pantothenic Acid. B vitamins help to provide energy by breaking down proteins, fats, and carbohydrates, as well as play an important role in supporting the nervous system.
