Easy Green Bean Casserole Recipe
Where did green bean casserole originate? Green Bean Casserole was first created in 1955 by the Campbell Soup Company. The original inspiration was to make use of 2 items that most American families always had on hand. Green beans and cream of mushroom soup. Perhaps, it was also to ensure that most American families always had those items on hand. Regardless of the original intent, it's been a staple dish on supper and special occasion tables all over the country ever since. It was a side dish designed for Thanksgiving, Christmas, Easter and other special holidays.

I'm so glad she did, I love her take on this green bean casserole, and I'm delighted she allowed me to pass on her homestyle creation to all of you. It's a keeper in my cookbook and one you can find on our holiday menu every year.
