This Crockpot Sweet Potatoes With Marshmallows recipe is going to bring back some memories. Tender sweet potato cubes are perfectly seasoned with your favorite fall spices and sweetened with maple syrup and, of course, melted mini marshmallows.

A Super-Simple Holiday Side Everyone Will Love!

One of my favorite parts of Thanksgiving as a child was seeing the mini marshmallows in the casserole dish. I was always so amused with the fact that we could eat mini marshmallows with dinner. And now I can cook them anytime with this Crockpot Sweet Potatoes With Marshmallows recipe.

Fortunately, these little fluffy marshmallows pair perfectly with sweet potatoes. Whoever thought of this is pure genius! Sweet potatoes are naturally sweet and they become even more delicious when you add melty mini marshmallows.

Marshmallows aren’t the only star of the dish though! The sweet potatoes are tossed with pumpkin spice – the perfect fall spice blend. To top it all off, we’re cooking the sweet potatoes in a crockpot. So, not only is it delicious but so easy.

The Ingredients You’ll Need

Here is what you need to make this easy crockpot recipe. Let’s hit up the pantry and get started!

  • Sweet Potatoes: Delicious and good for you! Did you know that one sweet potato packs in 400% of your daily Vitamin A needs?
  • Brown Sugar: Brown sugar caramelizes perfectly onto the sweet potatoes.
  • Maple Syrup: I always suggest using pure maple syrup instead of the fake stuff.
  • Butter: Unsalted is preferred here. But if you only have salted butter, then omit the salt in the recipe.
  • Pumpkin Pie Spice: The best spice blend to keep handy during the fall season!
  • Salt: A little pinch of salt brings out the overall sweetness of the dish – believe it or not!
  • Mini Marshmallows: My favorite part! Their sweetness is perfect and I love the gooey texture they add.

What’s the Difference Between Candied Yams and Sweet Potatoes?

Yams and sweet potatoes are a bit different even though they look the same.

Yams are starchier and are not as sweet as sweet potatoes. If you were to eat them alone, they would taste more like a regular potato. Therefore, when you make candied yams, you may need a bit more sugar or other sweeteners to make them taste “candied”. Also, sometimes candied yams use orange juice or brandy to help bring their flavor to life.

Sweet potatoes are naturally sweeter. They do not require as much sugar to taste delicious. But, that doesn’t mean that you can’t add maple syrup or sugars to them to make them taste better!

How to Make Crockpot Sweet Potatoes with Marshmallows

You’ll have these yummy sweet potatoes cooking away in the crockpot in no time. Here’s how to make this recipe.

First, prep your slow cooker. Simply spray your crockpot with non-stick cooking spray so the goodies don’t stick to the bottom!

Then, put everything in the crockpot. Give it a good stir so the spices and sweeteners coat the sweet potatoes.

Set the crockpot and wait. It will take about four hours to slow cook the sweet potatoes.

Finally, add the marshmallows! About five minutes before serving, you’ll stir in the mini marshmallows. Then, after about 3-4 minutes, this delicious sweet potato dish is ready!

Recipe Notes

Here are a few things to keep in mind when making this sweet potato recipe.

  • If you like your sweet potatoes with toasted marshmallows, you can spoon them into a casserole dish after they are cooked. Then, top with marshmallows and place in the oven at 400°F for about 10 minutes or until the tops of the marshmallows are browned and toasted.
  • Add nuts! If you like nuts, you can add some nuts for a crunch. You can use pecans or walnuts, or even candied pecans!

  • To add some green vegetables to your menu, try my Sauteed Green Beans with Bacon or The Best Green Bean Casserole.
  • Don’t forget to try my Garlic Mashed Potatoes for those of you who need both regular potatoes and sweet potatoes for your holiday spread!
