'Shroom Burger

Menu Item Description

A crispy fried, whole Portobello mushroom filled to the brim with melted muenster and cheddar cheeses, topped with fresh lettuce, vine ripened tomato, and savory ShackSauce.

Culinary & Taste Profile

'Shroom Burger is griddled to order on a screaming-hot flat top using Shake Shack's proprietary 100% Angus beef blend (sirloin, brisket, and chuck). The searing process caramelizes the exterior to lock in savory juices and rich umami flavor, complemented by a warm, butter-toasted non-GMO Martin's potato bun and melted American cheese.
