Sweet Potatoes with Marshmallows Ingredients
The ingredients needed to make sweet potatoes with marshmallows look a lot like you are making a dessert! Maybe that’s why this side dish is so popular.
- Sweet Potatoes: You’ll need four cups of diced sweet potatoes. Grocery stores often sell them already peeled and diced. Or you can buy the whole potatoes and prep them yourself. Some stores even sell mashed sweet potatoes during the holidays, and they would work well in this recipe.
- Sugar: We used granulated sugar as the sweetener. Brown sugar would taste great, too but keep in mind that it will change the color of the casserole.
- Milk: Whole milk helps make the sweet potatoes smooth and creamy.
- Butter: Melted butter is added for the fat and the flavor.
- Eggs: The eggs add moisture, provide structure and add to the creaminess.
- Vanilla: We added one teaspoon of vanilla extract to give the dish more flavor.
- Seasoning: This recipe uses ground cinnamon, salt, ground nutmeg, and ground ginger to season the sweet potato casserole.
How To Make Sweet Potatoes with Marshmallows
There are three easy steps to make sweet potato casserole with marshmallows. Cook the sweet potatoes, add the casserole ingredients, and bake!
Sweet Potatoes: Peel and cube your sweet potatoes if you didn’t buy them already prepped. Put the cubes in a microwave-safe bowl and cover them with cold water. Cook them in the microwave on high until tender. This step could also be done on the stovetop.
Casserole: After draining the water from the cooked potatoes, add the granulated sugar, milk, melted butter, eggs, vanilla, ground cinnamon, salt, ground nutmeg, and ground ginger. Mix until smooth and combined. Pour into a greased casserole dish.
Cook: Bake the sweet potatoes at 350˚F for 30-35 minutes.
Marshmallows: Remove the pan from the oven and top the casserole with marshmallows. Place under the broiler for 1-2 minutes until golden brown.

IDK if it was my microwave or what but when I took the cubed sweet potatoes out they were tender enough to stick a fork into but not nearly tender enough to blend in a blender. And even after mashing by hand and putting back into the microwave in increments to avoid over cooking they were still chunks that weren’t tender so I’m going to bake until I’m satisfied before topping with the marshmallows. I should have tried the recipe before committing to bring them to a dinner. Well hindsight is 20/20 😂

How and when do you add the sweet potatoes? On top of the mixture? Mix it together?

Hi Julie,
You’ll cook and drain the cubed sweet potatoes, add the other ingredients to the cooked sweet potatoes (except the marshmallows) and beat until smooth, spread the mixture out in a casserole dish, and bake. The video and photos in the post can give you more detail into exactly how I make them. I hope that helps! Let me know if you have additional questions.
Happy Thanksgiving,
