That’s right, for a limited time McDonald’s is adding a “premium” sirloin burger to its U.S. menu. Weighing in at one-third of a pound, the new sandwich is the biggest burger on McDonald's menu since 2013, when the chain retired its Angus Third Pounder.
While there are no official nutritional stats out for the new menu addition yet, the Angus Third Pounder came in at 750 calories and carried 39 grams (nearly a day’s worth) of artery-clogging fat. We doubt the Sirloin Burgers are much better considering they are the same size and sit between the same soggy buns.
Although the chain has stated that these sandwiches are “officially” rolling out by May 11, they have been popping up somewhat randomly across the nation at select locations. If you feel compelled to try one—despite the hefty calorie-tag—we suggest opting for a plain or Steakhouse style variety (grilled mushrooms, onions, white cheddar cheese and peppercorn sauce) instead of the BLT and cheese version, which likely packs more calories. And if you can split your burger with a friend—and skip the fries and soda, even better. Trust us, your waistline will thank you!
