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.

    For some reason, I’ve never tried adding pecans to my sweet potato casserole. I will now! Thanks for the idea.

    Sweet potato casserole is one of my most favorite Thanksgiving sides, ever! And, I’m a huge Friends fan. I’ve lost count of how many times I’ve seen every episode, but I could probably recite the scripts! 🙂 This one with Brad Pitt was such a good episode!
