Home Baked Sweet Potato Casserole

Well another year is almost gone and my a favorite holiday is almost here. I love when family comes over and we spend a few hours together. When we lived at the farm we had a huge gathering of family and friends. We always made some kind of Thanksgiving craft, wrote down what we are grateful for and played games. Of course we ate so much we needed a nap and then went back and ate some more.

People do not always serve turkey for Thanksgiving but our family does. I have had Turkey since I was a little girl. I love the stuffing best. I have added that recipe so you can try it too. It is so delicious, my mouth waters just thinking about it.

There are so many side dishes to make for Thanksgiving. But one recipe you need to make is Home Baked Sweet Potato Casserole.

Americans love adding marshmallows to sweet potato casserole, and the story behind it is interesting. Sweet potatoes have been popular in America since Colonial times, brought over from Central and South America.

In the Southern climes of the U.S., these crops were very successful. In the 1800s, they increasingly started becoming associated with holiday meals.

According to Saveur magazine, in 1917, a marshmallow company called Angelus Marshmallows published a recipe for sweet potatoes with marshmallows in a recipe booklet. Marshmallows were now commercially available and affordable, so they were an exciting novelty sweet. And that is how it got started.
