More About This Recipe

  • Whether you bake sweet potatoes in the oven or cook them in the slow cooker like in this recipe, you probably have come to associate sweet potato casserole with Thanksgiving. And what makes it really special? The marshmallow topping, of course! Though nowadays it doesn’t seem too out of the ordinary to top a savory dish with fluffy marshmallows, take a step back and you’ll find yourself wondering: who came up with such an unlikely, delicious pairing? You may be surprised to find out that though candied sweet potatoes were being made in America in the 1800s, it wasn’t until the turn of the 20th century that it was suggested to top candied sweet potatoes with marshmallows. It’s been reported that the company Angelus Marshmallows promoted the first recipe to use marshmallows as a topping for sweet potato casserole as a way to sell their product, and it picked up steam from there. Now you’ll have a hard time finding a table in the United States that doesn’t serve this unique dish on Thanksgiving. First time making sweet potatoes? This slow-cooker version is foolproof, but if you have any questions or want to learn more before you get started, check out our easy-to-follow how-to guide.
