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.”

"We are excited to be a partner on the new Signature Slingers, which brings together the craveability of pure beef with the juiciness of mushrooms, creating a great tasting cheeseburger that guests will only be able to get at SONIC,” said Bart Minor, president of the Mushroom Council, which provides marketing and education on behalf of the nation's mushroom growers and importers. “The trend of blending mushrooms into a burger patty has been atop a number of food trend lists this year and we can’t wait for guests to experience SONIC’s uniquely delicious creation."

The Classic SONIC Signature Slinger contains approximately 340 calories.
