Homemade twice baked potatoes are one of my favorite side dishes. 

I love that I can get my own serving that no one else has touched. I love that it is already made and portioned out. 

And I love how pretty it looks to have a plate of them on the table.

Well, have you ever had easy twice baked sweet potatoes with marshmallows?

It’s a twice baked potato that’s really a loaded sweet potato with all the flavors of a classic recipe from Thanksgiving dinner. But you can eat it anytime.

It is a perfect side dish, and of all my sweet potato recipes, this really is the best way to serve them. 

It’s like getting a mini version of a classic sweet potato casserole in your own little potato shell. It is already made, portioned out, and no one else has touched your food.

Think of the sweet potato skins as a natural and organic, 100% compostable bowl to host your sweet potato pie. There are so many great things about it, I don’t think this dish can get any more perfect.

What ingredients are in Baked Sweet Potatoes with Marshmallows?

  • Sweet Potatoes: try to pick potatoes that are the same size so they take the same amount of time to cook
  • Melted Butter: this adds a layer of flavor and helps the filling stay smooth and fluffy
  • Brown Sugar: use dark brown sugar for a more molasses flavor; light for a less strong flavor
  • Ground Cinnamon: this earthy spice is my favorite one to mix with brown sugar and butter because it works well in sweet and savory dishes
  • Mini Marshmallows: you must use the little ones; if you only have regular marshmallows, cut them into small pieces so they will melt and toast evenly

Pro Tip: Most yams found in a grocery store in the United States are actually sweet potatoes. True yams have a tree like bark on the outside and a really starchy white inside. The orange yams that you buy are actually sweet potatoes.

If you prefer to call these baked yams with marshmallows, you can, but being true to my full disclosure policy, these are sweet potatoes. And the nutritional value is much higher than what is in real yams.

How to make baked sweet potatoes with marshmallows:

  1. Place potatoes on a rimmed baking sheet and bake.
  2. Scoop out cooked sweet potato flesh.
  3. Mix in other ingredients in a large bowl with a hand mixer or potato masher.
  4. Scoop sweet potato mixture into skins, place in a baking dish, and top with a cup of mini marshmallows.
  5. Broil until toasty and serve!

Pro Tip: You can bake the potatoes in the oven like I write in this recipe, or you can use your instant pot or crock pot. The important thing is you want your potatoes baked and warm to get the gooey marshmallow filling you are mixing in with the potato flesh.

Can baked sweet potatoes with marshmallows be made ahead of time?

Yes! The best part is you can do everything ahead of time but toast the marshmallows. Toasted marshmallows should happen right before serving whether in the oven or with a hand torch.

But always be sure to heat the potatoes through and then add the marshmallow topping to the single serving sweet potato casserole before toasting.

Can you freeze baked sweet potatoes with marshmallows?

Yes! But not with the marshmallow topping. The baked sweet potatoes marshmallows will make a mess and not thaw well coming out of the freezer.

So if you have leftovers, remove the toasty marshmallows, wrap in plastic wrap and store in a freezer safe container for up to three months.

If you make extras, you can freeze them before you put the marshmallows on top and have an easy freezer side waiting for another day.

Can dogs eat baked sweet potatoes with marshmallows?

Plain sweet potatoes are fine for dogs to eat every once in a while. 

But these small sweet potato casserole dishes are loaded with marshmallows and brown sugar which is not good for your dog.

So while this won’t hurt your dog, this is not a good thing to feed your dog.

  4. Place potatoes in a 9x13 casserole dish.
  5. Bake for 45 minutes or until they are soft to a fork.
