Every Sunday through June 28, head to Shake Shack and score a FREE Chicken Shack Sandwich or Chicken Shack Lettuce Wrap with a $10+ purchase when you use promo code CHICKENSUNDAY. Don’t miss out—find your nearest Shake Shack and check out the upcoming freebies!

The Chicken Shack from Shake Shack features a crispy, all-white meat chicken breast topped with fresh lettuce, pickles, and creamy buttermilk herb mayo, all served on a soft toasted bun. For a lighter option, you can enjoy it as a lettuce wrap instead of a bun. It’s a flavorful, satisfying choice that’s perfect for chicken lovers—and even better when you can get it free with a qualifying purchase.
