Sonic Drive-In has introduced new SONIC Signature Slingers, a first of its kind in fast food. The cheeseburger patty is made with 100-percent pure beef blended with savory mushrooms and seasonings. It is the first instance of a quick-serve restaurant chain using a burger patty made with beef blended with mushrooms, using less beef in each patty.
“The Signature Slingers is a first-of-its–kind fast food cheeseburger, which delivers the juicy savory deliciousness you expect from a burger in a way that makes you feel like you’re getting away with something,” said Scott Uehlein, vice president of product innovation and development for SONIC. “Adding mushrooms right into the burger patty amps up the incredible flavors of the 100-percent pure beef and seasonings you get in each bite. This burger truly raises the bar for every other restaurant.”
