Ingredients

To make this recipe, you need a handful of ingredients:

  • Sweet potatoes – They can vary in size, we need almost 1.5 pounds of sweet potatoes for this recipe. You can boil or roast them to make the casserole.
  • Egg – We are going to use one large egg as a binding agent.
  • Spices – Cinnamon and ginger add a lot of flavor to this dish. Make sure to use dried powdered ginger since it has a more sweet and subtle flavor.
  • Maple syrup – To sweeten this casserole and add more flavor, I used maple syrup. You can also use honey, granulated sugar, brown sugar or even stevia.
  • Topping: You need a combination of marshmallows, brown sugar and pecans. I used mini marshmallows and chopped pecans, but it’s also possible to use regular marshmallows and whole pecans.

Instructions

Cook the sweet potatoes

You can use two different methods to cook your sweet potatoes:

  • Stove top: Wash and peel the sweet potatoes. Cut them into cubes and place them in a large pot. Cover the sweet potatoes with water and bring it to boil over medium heat. Cook for about 15 to 20 minutes until fully cooked. Drain the water and let the sweet potatoes cool.
  • Oven: Wash the sweet potatoes and pierce them several times with a fork. Rub some olive oil all over the sweet potatoes and wrap them in foil. Bake in the oven at 400 degrees F for about 30 to 40 minutes until fully cooked.

Prepare the casserole

  • Once the sweet potatoes are cool enough to handle, peel them and place them in a bowl. Mash the sweet potatoes using an electric mixer, a potato masher or a fork.
  • Add in the egg and the maple syrup or any other sweetener of your preference. Season with cinnamon and ginger then fold in the marshmallows. Save about 1/2 cup marshmallows for the topping.
  • Transfer the mixture to a casserole dish and top it with the remaining marshmallows, pecans and brown sugar.
  • Bake it for about 30 minutes. Serve sweet potato casserole warm or at room temperature.

Serving suggestions

Sweet potato casserole is usually served as part of a Thanksgiving spread alongside mashed potatoes, roasted sweet potatoes, roasted turkey, stuffing and cranberry sauce. It’s a nice addition and the color gives the table nice fall vibes.

Absolutely! You can make this sweet potato casserole with pecans up to three days in advance and simply reheat it in the oven at 325 degrees F until it’s completely heated through, about 30 minutes.

While yams and sweet potatoes are not the same thing, it’s possible to use canned yams to make this casserole. Keep in mind that they might have added sugar in which case you won’t need additional sweetener.

If you’re not a fan of marshmallows, simply leave them out. There will be no change in the process or the cooking time.

  1. I am all about sweet potato casserole at Thanksgiving. However, I’ve never seen it done with pecans AND marshmallows! Seems people like it one way or another but together the combination is genius!

    1. Me too, love sweet potato! I guess being new to Thanksgiving helps with creativity, I love pecans and marshmallows together!

  2. 5 stars
    I’m very familiar with yams. Initially, they’re native to West African and some Caribbean countries and are larger and a lot more starchy than sweet potatoes so they’re used a lot with savory stews and soups. I recently discovered that in the US, yams and potatoes are used interchangeably so I was initially thinking about actual yams when I watched that episode and remember being seriously grossed out about him adding sweets to “yams” and everyone loving it! Lol! Well now I know and yes that combo is absolutely delicious as a dessert!

    1. Hi Lois! Ok this is new to me! I didn’t know sweet potatoes and yams are not the same. Well, it’s been only 2 years since I had my first sweet potato but next time I’m in a super market, I’ll make sure to get both and see the difference. Thank you so much!

  3. I refused to eat sweet potato casserole as a kid…except for the marshmallow topping! But I’ve learned to love it, and yours looks really delicious. I’ll have to give this recipe a try

  4. Totally making this for Thanksgiving! It looks SO delicious and perfect. Your photography is gorgeous, too!

  5. 5 stars
    This is an interesting recipe. I love how light and fluffy this looks. I’ve never had sweet potato with marshmallows before. I bet it tasted awesome.

  6. 5 stars
    This looks incredible! I’d love to make this recipe for my very own “Friendsgiving” this year! I love how creamy and decadent the recipe turns out. It’s the perfect comfort food during the cold months and holiday season!

  7. 5 stars
    You’re talking my language… from LOVing friends, to adding marshmallows and pecans to the sweet potatoes! Pinned this!

  8. 5 stars
    I have never tried a sweet potato casserole. It just always sounded strange to me to have a sweet something with marshmallows as a side dish… but your description makes it sounds really delicious. Maybe if I think of it as a dessert I could get on board with it? And yes, every episode of Friends is my favourite but now with the US Thanksgiving around the corner I’ve been remembering that particular episode also 🙂 So funny!

  9. i have never been into casserole but your version looks so fluffy _ with all that pecans.
