McDonald’s, Burger King, and Wendy’s watch out, there’s a new burger in town and it’s made by the guys who have the meat! That’s right Arby’s has moved into the burger selling space!

Arby’s new burger is made with a blend of 48% ground beef and 52% American Wagyu, and is a cross between Japanese Wagyu and top American cattle breeds. Arby’s says it’s the largest single patty in the fast food genre, with a raw weight of 6.4 ounces. That would be 50% larger than McDonald’s Quarter Pounder and will be prepared sous-vide style, using a technique more common in fine dining. The cooking method results in a juicy burger with a crispy outer edge and slightly pink center, Arby’s said in a statement.

The Arby’s Wagyu Steakhouse Burger is topped with American cheese, shredded lettuce, tomato, pickles, red onion and a special burger sauce and served on a toasted brioche bun. Guests can also choose to add bacon and ranch.

“Boring burgers are a fast-food staple, so Arby’s felt compelled to raise the bar with a Wagyu Steakhouse Burger. Instead of focusing on making billions of mediocre burgers, we’re taking a stance on high-quality meat that deserves to be cooked properly,” Patrick Schwing, Chief Marketing Officer of Arby’s, said in a statement. “As the meat experts, we’ve spent over two years of dedicated research and development to deliver a premium burger that redefines what’s possible from a drive-thru.”

The new Arby’s burger will be available for a limited time only at participating U.S. locations while supplies last.
