"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.”

Beginning Monday, March 5, guests can enjoy two Signature Slingers cheeseburger options to satisfy their guilt-less burger cravings. The Classic SONIC Signature Slinger is topped with fresh lettuce and tomato, diced onions, crinkle-cut dill pickles, mayo and melted American cheese served on a bakery-quality brioche bun. The Bacon Melt SONIC Signature Slinger is made with crispy bacon, layered with melted cheese and mayo served on a bakery-quality brioche bun.

"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."

Guests can pair the new SONIC Signature Slingers with a SONIC Fruit Fizz™ for the ultimate lunch, dinner or snack, but only for a limited time.
