In 1955, a Campbell test kitchen chef, Dorcas Reilly, invented the classic holiday dish. It's a quick, easy side dish that uses only six ingredients and can be prepared in 10 minutes. Nearly 65 years later, it's still one of the most popular holiday dishes, found on Thanksgiving Day tables across the country. In fact, Green Bean Casserole recipes were viewed more than 6 million times last holiday season!
