Agaricus bisporus

Also known as Portabello, is the larger relative of white Agaricus and Crimini, they're excellent stuffed, grilled, in sauces and sautés. Their deep flavor and firm texture make Portabellas a great meat substitute or vegetarian entrée.


Look for mushrooms with a fresh, smooth appearance. Portabellas are best if cooked. Grilled or broiled whole they are perfect as a vegetarian burger, or sliced and sauted for salads, pizzas or pastas. Chop up and use in soups and sauces for a rich, meaty taste.

Storage and Handling

Ostrom's portabella mushrooms don't have to be used immediately. They'll stay fresh for 7-10 days if you keep them refrigerated. Store bulk mushroom in a paper bag. If you purchase Ostrom's portabella mushrooms in our shrink-wrapped package, it's a good idea to open up the top, remove the plastic wrap from packaged portabellas and cover loosely with a paper towel.

Don't forget! You do not have to wash, soak or peel portabella mushrooms. Simply wipe clean with a damp paper towel immediately before using and trim off the root.
