Sirloin Burger

What is it?

Coarsely ground sirloin gives this patty a looser, more steak-like texture than the usual finely formed fast-food burger. It sits on a toasted brioche bun, which puts the whole sandwich a step above the standard hamburger lineup. Depending on the version, it comes with toppings such as Swiss and grilled onions, or blue cheese and bacon, with lettuce and tomato on the simpler build. It's a larger, more premium-style burger in the chain's range, built around the sirloin patty rather than the regular ground beef used elsewhere on the menu.
