A dessert-like side dish
The first recipe for sweet potato casserole was published in 1917 by a marshmallow manufacturer. It was a clever marketing ploy to get people to use their marshmallows in more recipes. So, we have the Angelus Marshmallow Company a big thank you for introducing us to such a sensational Thanksgiving side dish.
There are many variations of this casserole floating out there, however, once you try this one, you won’t need any other recipe ever. This is hands down the best sweet potato casserole you will ever make! It is super creamy, and loaded with marshmallows, and the whole family will beg for more at every Thanksgiving and Christmas!
The potatoes are boiled and mashed, blended with some brown sugar, nutmeg, and cinnamon to elevate the fall flavors.
The best part of this dish is the brown sugar cinnamon filling. Also, it is a delicious, mid-layer of cinnamon goodness. The crunchy topping paired with sweet marshmallows is another highlight of this casserole. It’s very comforting, and it tastes even better with a cinnamon filling and buttery cinnamon pecan topping!
This sweet potato casserole topped with pecan streusel and marshmallows is so good, that many people serve it as a dessert instead of a side dish. It could be used for a meal too. You can alter this recipe if you like but try it as written the first time and you will be glad you did.
The beauty of this Thanksgiving sweet potato is that you can make it a few days in advance and refrigerate it. You can choose to just assemble it, wrap it tightly in plastic wrap, and bake it when ready. However, if you do refrigerate it before baking, we would suggest removing it from the fridge at least 30 minutes before baking.
Also, you can bake it first, and let it fully cool. Then, wrap it tightly in plastic wrap and refrigerate it for up to 2 days. Cover with foil and warm it up in the oven before serving. A true holiday staple, that is perfect for Thanksgiving, Christmas, or Easter!

Sweet potato layer:
