Shake Shack Shack Stack® Price, Nutrition and Allergens
What Is the Shake Shack Shack Stack®?
The Shack Stack® is a Shake Shack iconic mashup combining the best of both worlds: a quarter-pound Angus beef patty topped with a full ‘Shroom Burger (crisp-fried portobello mushroom filled with melted muenster and cheddar cheeses). It’s finished with lettuce, tomato, and ShackSauce on a toasted potato bun. Juicy, crispy, cheesy, and indulgent—it’s a fan-favorite for a reason.
