The promotion runs through August 2, 2026, and is open to diners who order a tender item in-store or through the brand’s loyalty app. Each winner will receive a punch card valid for a free three-piece tender meal every month through July 2027. The company is also introducing a $9.99 value bundle featuring the new tenders alongside their signature Shack potatoes, a side, sauce, and a drink.

Founded in 1956 by John and Iola Sobeck, the restaurant chain has built its reputation on fresh, never-frozen American chicken. According to Cliff Lunny, the company’s president, the revamped recipe utilizes a proprietary batter-and-flour blend designed to enhance both texture and flavor. As the brand eyes further expansion through franchising, this menu update serves as a cornerstone of its 70th-anniversary milestone.
