Sonic Drive-In has revamped its fry offering with the debut Tuesday of Natural-Cut Fries at its 3,500 drive-ins nationwide.

The new skin-on version of the fry is made from whole russet potatoes and offers guests a “higher quality fry with a crispy crunch,” according to parent company Sonic Corp.

Natural-Cut Fries replace the previous fry offering, though the chain will continue to offer its Tots.

“Fries are a staple at any quick-service restaurant, so we have worked to create a natural-cut, skin-on fry that delivers lots of flavor while maintaining the crispy but fluffy texture our customers desire,” Claes Petersson, Sonic’s vice president of product innovation, said in a statement.

The Oklahoma City-based company said that during market research, consumers scored the skin-on fry higher on quality, crispness, texture and overall product than its past offerings.

With the new item, Sonic joins other large quick-service chains that have made changes to their French fries. In September, Miami-based Burger King Worldwide Inc. introduced lower-calorie crinkle-cut French fries, dubbed Satisfries, which it said had significantly less fat and fewer calories than its competitors’ offerings. Dublin, Ohio-based Wendy’s reformulated its fries in November 2010 to a natural-cut version with sea salt.

Sonic’s rollout of new French fries follows its release in the past of week of a new lineup of spicy items, which includes a Classic Spicy Chicken Sandwich, Island Fire Spicy Chicken Sandwich, Island Fire SuperSonic Cheeseburger and Southwest Chipotle Breakfast Burrito.

The new spicy items include cayenne pepper and habanero sauces, and are part of the chain’s limited-time offers.
