Shake Shack’s First Chicken Sandwich Flies Into Boston Today

The Chick'n Shack is here to stay, but follow it up with Patriots Jerod Mayo's Lineshacker for a limited time only.

Shake Shack fans with a penchant for poultry, here are your lunch plans. The New York-based burger chain debuts its first-ever chicken sandwich today at all Massachusetts locations.

The Chick’n Shack tops Shake Shack’s classic potato roll with a crispy, buttermilk-battered and fried chicken breast—from cage free, non-GMO birds, of course—plus shredded lettuce, pickles, and Shack-made buttermilk herb mayonnaise. New to the condiment line is Louisiana hot sauce, for those who need an extra kick.

The Chick’n Shack premiered at Shake Shack’s three Brooklyn locations over the summer, to much delight: It sold out in one day, before the company ramped up production and has kept it on the borough’s menus ever since. Demand led to its nationwide launch today, though the sandwich won’t be available at three New York City restaurants just yet.

Unlike the limited edition Surf N’ Shack lobster burger, a smoky sausage-topped Kreuz Market burger, and other one-offs, it’s here to stay. “The introduction of chicken marks a new era for Shake Shack, staying true to our core menu while continuing to innovate new items our guests have asked for,” Shake Shack CEO Randy Garutti said in a press release.

But after you finish your Chick’n Shack today, there is a special custard: Just in time for the NFL playoffs, Jerod Mayo’s Lineshacker is available through the end of January. The New England Patriots co-captain is a fan of Flour Bakery, so his specially-designed vanilla custard is swirled with the flavors of chef Joanne Chang’s pecan sticky bun, and topped with whipped cream and brown sugar cinnamon toasted pecans. All proceeds from Lineshacker sales go to the Boston Medical Center.
