OKLAHOMA CITY – Sonic Drive-In has taken two popular menu items and put them together to make a new limited time only (LTO) indulgent burger. The Sonic Grilled Cheeseburger adds a seasoned 100% beef patty to the QSR’s Grilled Cheese on Texas toast. It finishes with mustard, ketchup and diced onions.

“A grilled cheese sandwich becomes even more craveable when you pair the flavor with a savory 100% pure beef patty and extra toppings,” said Scott Uehlein, vice president of product innovation and development for Sonic. “Guests no longer have to choose between these classic menu items because the Sonic Grilled Cheeseburger simultaneously fulfills the need for both burger and grilled cheese sandwich, upping the cheese factor in a big way.”

The LTO Grilled Cheeseburger will be available until Sept. 26 while supplies last for $2.49. Customers can try one for half price when ordering online of through the Sonic app.
