This combination of mayonnaise, ketchup, Worcestershire sauce and spices for dipping chicken fingers was originally created at Guthrie's—the first chain to offer chicken-finger meals—by one of founder Hal Guthrie's kids, and the sauce became a big part of the restaurant's early success. Even though Guthrie's debuted the first version of this sauce, it’s the bigger chicken-finger chains that copied Guthrie’s concept (Zaxby's and Raising Cane's) that have made the secret sauce recipe iconic.

Here's how to join in on the fun and copycat your own version of this famous sauce at home, for dipping homemade Zaxby's Chicken Fingerz, or pre-breaded tenders, you buy in the frozen food aisle of your store.
