Panera Bread has brought two iconic foods together in one menu item. The bakery-café chain has introduced its new Grilled Mac & Cheese Sandwich launching nationally this month.

The fall mashup combines Panera’s signature Mac & Cheese, layered with fontina and mozzarella cheeses, sprinkled with Parmesan crisps and sandwiched between slices of classic White Miche, toasted to perfection. It joins the Sausage & Pepperoni Flatbread Pizza and limited-time Cinnamon Crunch Latte in the seasonal lineup.

“We couldn’t be more excited to bring our new Grilled Mac & Cheese Sandwich to market as the ultimate collaboration that our guests never knew they needed,” says Claes Petersson, Panera’s head chef and chief food innovation officer. “When launching new menu items, we always aim to surprise, delight and satisfy our guests – and we are confident that guests will love our expanded sandwich, flatbread pizza and coffee offerings this fall.”

To celebrate the launch, Panera has collaborated with Delicacies Jewelry to create a limited-edition golden noodle necklace. Mac & Cheese fans can enter for a chance to win one of 500 gold-plated necklaces for a limited time at PaneraMacNecklace.com. A portion of the proceeds from the collaboration will be donated by Delicacies to further both companies’ commitment towards fighting food insecurity.
