Easy Green Bean Casserole with canned green beans. One of our favorite make ahead Thanksgiving sides, this may be the best you'll ever have!

It's not a holiday (at least, not at our house) without this quick and easy Green Bean Casserole. We love it at Easter, on our Thanksgiving menu (of course) and Christmas.

When I was growing up it was tradition to have my Mom's whole side of the family over for dinner and a celebration on Christmas Eve. It was always served in pretty casserole dishes. This casserole went so fast, we always had two whole 9x12 pans of it, and we ate it all! Haha. It's safe to say I think it is the very best!
