Sonic’s Signature Slingers feature a new beef patty that’s made with 100 percent pure beef, seasonings, and savory mushrooms.
No, the mushrooms aren’t on top of the burger patty, they’re IN it.
There are two options that use it. The Classic Sonic Signature Slinger is topped with lettuce, tomato, diced onions, crinkle-cut dill pickles, mayo, and American cheese on a brioche bun. The second is the Bacon Melt Sonic Signature Slinger. It features bacon, melted cheese, and mayo on a brioche bun.
According to Sonic, the mushroom-enhanced patty “gives you all the flavor with none of the guilt.” The Classic Sonic Signature Slinger contains 340 calories.
The burger starts at $1.99 and is available for a limited time at participating locations.
