In fact, it wouldn’t be Thanksgiving or even Christmas for most of us without a Sweet Potato Casserole on the table.

This is one we’ve made and perfected over the years… and absolutely love.

I’ve opted for a nutty pecan topping, which provides a wonderfully delicious crunchy contrast to the creamy mashed sweet potatoes.

History of the Sweet Potato Casserole

Often, there is a side dish you most look forward to during the holiday feast. For many, that dish is sweet potato casserole.

But did you ever wonder what its origins are?

Much of them lie in the topping.

Celebrating the 100th year of the Sweet Potato Casserole, the Smithsonian writes:

“In the United States, sweet potato recipes can be found as far back as 1796, when Amelia Simmons published American Cookery.”

However, the Smithsonian notes, “The oldest recipe for candied yams is from 1889… Fannie Farmer’s 1918 recipe for ‘Glazed sweet potatoes’ calls for boiling the potatoes before coating them in a sugar syrup with butter and baking ‘until brown, basting twice with the remaining syrup’.”

Marshmallows or Pecans?

As I mentioned, much of the Sweet Potato Casserole’s origins lie in the topping.

The Smithsonian notes that a marshmallow-topped casserole is only a “thing” — thanks to Cracker Jacks.

Marshmallows were introduced into American households in 1907 by Angelus Marshmallows, the original maker of Cracker Jacks.

A decade later, and in an attempt to drive sales, they contracted Boston Cooking School founder Janet McKenzie Hill to write a cookbook featuring marshmallows. From fudge to hot cocoa, and yes, the first documented appearances of a marshmallow-topped sweet potato casserole.

The sweet potato casserole with pecans originated in the South and often contains milk or cream, brown sugar, and eggs.

For me, I like pecans a bit better than marshmallows.

What is the difference between Sweet Potato Pie and Sweet Potato Casserole?

Well? Not a whole lot. They’re both sweet, both incredibly delicious, and in my opinion, each has its own place at the Thanksgiving table.

A Sweet Potato Pie is served on the dessert table and generally has no topping. It’s also most often made with granulated sugar.

Sweet Potato Casserole, on the other hand, is considered a side dish and is served alongside mashed potatoes, stuffing, roasted vegetables. It usually has a topping of a nut streusel or sometimes marshmallows.

Why Do People Eat Sweet Potatoes for Thanksgiving?

Sweet potatoes have been popular in the American South since the founding of this country.

“The tropical region of Nigeria, the Ivory Coast, and West Africa is called the ‘yam belt,'” said Frederick Opie, Ph.D., Professor of History and Society at Babson College in Boston. “When Africans came to the new world as enslaved people, they substituted sweet potatoes for yams.”

In later years, a Sweet Potato Pudding or “Pone” became popular following the Civil War. Shortly thereafter, love for the beautiful orange tuber began traveling to the Northern regions of the U.S.

Today, whether we’re serving a Sweet Potato Soup, a Sweet Potato Pie, Mashed Sweet Potatoes, or this casserole, know that you’re continuing a beautiful heritage for Thanksgiving.

Frequently Asked Questions

Can I switch out the pecans for marshmallows in this Sweet Potato Casserole recipe?

Yes! Simply replace the topping with mini marshmallows; the cooking time should be about the same, you just will know it is done when the marshmallows are puffed and golden.

Can I make this Sweet Potato Casserole ahead?

You can make this casserole up to 12 hours ahead and keep it in the fridge ready for baking. Keep the topping separate to keep things crisp and sprinkle it over just before placing the casserole in the oven.

Sweet Potato Filling

  • 3 to 4 large sweet potatoes, peeled and chopped
