The burger features antibiotic-free, USDA certified Choice beef.

The burger is made with 6 oz. of all-natural, antibiotic-free, USDA certified Choice beef. It’s a burger that combines brisket and chuck for a different beef blend for consumers. The premium burger is served on a brioche bun with a steak knife through it.

“At Steak ‘n Shake, we’ve been on a quest to create the world’s best burger,” said Jim Flaniken, senior vice president of marketing for Steak ‘n Shake. “In pursuing this endeavor, we invested years visiting farms and working in chef kitchens around the world to develop the perfect blend of beef. The result is the Prime Steakburger — the tastiest burger on the market today. We are convinced no one will be able to match the quality and taste of the Prime Steakburger.”
