Kroger is getting into the meal delivery business.

The nation's largest traditional grocer said Monday that it has partnered with Indianapolis-based startup ClusterTruck to open delivery-only kitchens, also known as "dark" or " ghost " kitchens, in Indianapolis, Columbus, and Denver.

Here's what we know about the new concept, called Kroger Delivery Kitchen.

The kitchens will prepare and deliver restaurant-style meals and "change the wayAmericans access freshly prepared meals," Kroger said in a news release.

"The way our customers order and receive meals is evolving, and ClusterTruck's innovative culinary and digital design is cracking the code for the future of profitable meal delivery," said Yael Cosset, Kroger's chief information officer.

Kroger will not charge delivery or service fees, making it cheaper than other delivery options such as Uber Eats.

"Kroger Delivery Kitchen Powered by ClusterTruck will allow our customers to access restaurant-quality fresh and delicious meals like never before and without having to pay excessive service or delivery fees," Cosset said.

ClusterTruck software uses algorithms to optimize operations, which ensure orders are delivered within seven minutes of preparation, Kroger said. Meals are delivered within 30 minutes of ordering, on average.
