As Chick-fil-A toys with adding macaroni and cheese to its menu, customers in Murfreesboro and Nashville will be playing a role.

The Georgia-based chicken-sandwich chain is currently testing the dish as a side items in several markets, including Baltimore, Maryland, Greensboro, North Carolina, Houston and San Antonio, Texas, and Phoenix, Arizona.

"These tests will help Chick-fil-A decide whether or not the menu item will become available nationwide in the future," the company said in a statement sent to USA TODAY.

The company launched the mac and cheese menu item in July 2017 as part of a family-pack meal kit, according to its website.

A manager at the Chick-fil-A store on Memorial Boulevard in Murfreesboro said mac and cheese — made from a blend of American, cheddar and Romano cheeses — has been offered since late 2017. Customers have the option of upgrading to a mac and cheese side for an additional 45 cents, according to in-store menus, or ordering small or large servings a la carte. A small serving is $2.35.

The Murfreesboro store on Old Fort Parkway also carries it. It is also available in Nashville on Charlotte Pike and Nolensville Road, as well as Old Lebanon Dirt Road in Hermitage.

Customers in test markets can also order mac and cheese off the catering menu as a small or large tray option, Chick-fil-A says.
