The Grilled Cheese Burger starts with the brand’s signature grilled cheese sandwich on buttery Texas Toast and adds a seasoned, 100 percent pure beef patty, plus mustard, ketchup, and diced onions. It’s also available as a double featuring a duo of beef patties.
You can find the Grilled Cheese Burger at participating Sonic locations nationwide for a suggested price of $2.49 through September 26, 2021 while supplies last.
Sonic is also encouraging fans to try one for half-price when you order online or through the brand’s app. The reward is valid for one half price Grilled Cheese Burger or Grilled Cheese Double Cheese Burger.
