Sweet potatoes, butter, and brown sugar are baked then topped with mini marshmallows to make my traditional Sweet Potatoes with Marshmallows.
Sweet Potatoes with Marshmallows have been a part of my Thanksgiving dinner for as long as I can remember! They were always on our family table when I was a kid and now I make them every year.
We use canned sweet potatoes for this dish. I find it is an easier alternative. This dish is so quick and easy to make, and that is super important because our Thanksgiving dinner, like most people’s, is an all day affair.
I almost always do all of the cooking for our family Thanksgiving dinner. There are dishes that I make homemade and then there are recipes like these Sweet Potaotes with Marshmallows where I take a little help from the grocery store.
It really helps this huge meal be easier to make. I always make my Super Soft Yeast Rolls from and the this super impressive Libby’s Pumpkin Roll from scratch, among other dishes.
I always put the sweet potatoes in the oven while the turkey is resting. It is the perfect amount of time for these yummy sweet potatoes to get hot.
How to make Sweet Potatoes with Marshmallows:
Preheat oven to 350°. Spray a 13″ X 9″ casserole dish with cooking spray.
Drain two 40 ounce cans of sweet potatoes. Cut large chunks into bite sized pieces and spread evenly in casserole dish.
Top sweet potatoes with 1/4 butter cut into cubes. Sprinle with 1/8 cup brown sugar.
Bake for 25-30 minutes or until the sweet potaotes are hot. Spread 4 cups miniature marshmallows over top and return to the oven until the marshmallows begin to brown, about 5 – 7 minutes.
Make sure to watch them closely so the marshmallows don’t melt.
We don’t use too much brown sugar in this dish. The sweet potatoes are already sweet, and then we put mini marshmallows on top.
To me all of those things make this dish taste just right. Not too sweet.

Notes
My recipe is very similar to this reicpe by Pillsbury. You could use the large marshmallows if you want, but I prefer the mini ones.
