                                According to the company's official FAQ, Smashburger uses a combination of beef tallow and canola oil to fry their standard french fries. This unique blend is a key element in giving their fries a rich, savory taste that sets them apart from the competition. For their signature Smashfries, a different process is used, with a blended oil tossed with rosemary and garlic after frying.
