Big Mac Jacked: McDonald's Iconic Burger Now Bigger, and Smaller

The Big Mac is getting an update. Select McDonald’s restaurants are trying out a two-patty, one-third-pound Grand Mac, and a single-patty Mac Jr.

The Big Mac is finally getting an update. Unchanged in America since its debut in 1967, the iconic multi-hyphenate-ingredient burger and subject of that familiar jingle is being tested in new supersize and mini versions until June.

Select McDonald’s restaurants in central Ohio are currently trying out two new Big Mac burgers — a two-patty, one-third-pound Grand Mac; and a single-patty Mac Jr. that’s “easier to eat on the go.” The new granddaddy of burgers costs $4.89, and the mini Mac is priced at between $2.39 and $2.59.

While other fast food chains have supersized their best-selling burgers with items such as Wendy’s Quad Baconator and Burger King’s Triple Whopper, the Big Mac has held steady. But customers wanted innovation, Scott Nickell, president of McDonald’s Central Ohio Co-op, explained in a press release.

“They wanted different ways to enjoy the one-of-a-kind Big Mac taste, and we are proud to test this newest menu item that provides our customers with choices that fit their needs," Nickell said.

“This is a great way to celebrate our iconic Big Mac sandwich,” a spokesperson for McDonald’s told NBC News. “We’re always evolving our menu and providing our customers with new and exciting food innovations, and we look forward to learning more from this test.”

McDonald’s has been doing a lot of tinkering lately, introducing bottomless French fries and table service at a swish new franchise in Missouri, providing free tablets to diners in the U.K., and launching the popular all-day breakfast last year.

The Grand Mac and Mac Jr. are available at participating McDonald’s restaurants in central Ohio until June 6.
