That ShackBurger or Shack Stack will be avocado-less no longer as Shake Shack on Wednesday added avocado to its permanent menu.
The fast-casual burger chain also announced the addition of bacon as a limited-time sandwich topping.
Shake Shack’s new Avocado Bacon menu is available through June 30 at all U.S. locations. The menu features an Avocado Bacon Burger (cheeseburger with avocado, bacon and ShackSauce) and an Avocado Bacon Chicken Sandwich (crispy chicken breast, avocado, bacon, lettuce, pickles and buttermilk-herb mayonnaise).
The chain’s bacon comes from Niman Ranch, a network of more than 700 family farmers and ranchers known for raising sustainable livestock.
Avocado can be added to any Shake Shack sandwich for about $1.25. The chain said avocado has been one of its most-requested menu items.
In February, Shake Shack announced a series of limited-time chef collaborations at select restaurants around the country. The one-day-only pairings started last month and feature chefs such as Dominique Crenn, Sarah Gruenberg and Pinky Cole. The chain said more chef collaborations are slated for the future.
