This Baked Sweet Potato Fries with Toasted Marshmallow Dip recipe is sweet and salty heaven. It’s a wonderful appetizer or side dish for birthday parties, holiday tables or weeknight dinner fun.
I cannot take credit for this one. There is a really good burger place in Lawrence, Kansas called The Burger Stand. They have a condiment station that rivals any I have ever seen. All of the condiments are homemade, and all incredible.
And they had one, mysterious sweet flavor called toasted marshmallow. I thought that it was the coolest idea ever.
All it is – toasted marshmallows blended with some cream. How fun would this be for a kid’s birthday party or holiday table? Something a little different, and very, very fun.
Ingredients //
All it takes is 5 simple ingredients including sweet potatoes, olive oil, sea salt, marshmallows and heavy cream.
Sweet Potatoes. Any shape or size sweet potato will do. When you get home from the store, thoroughly wash, scrub, peel and cut into batons about ½-inch thick (see steps below!).
Marshmallows. I like the Jumbo marshmallows you can find in the baking aisle of most grocery stores. Regular or mini marshmallows can also work, just keep an eye on them as soon as you put them in the oven.
How to Cut Sweet Potato Fries
The cooking time will vary depending on the thickness of your potatoes, but this is the method I stick to every time:
- Wash, scrub and peel the sweet potatoes.
- Cut off the stem ends.
- Slice all four sides of the potato to square it off.
- Make ½-inch slices down the potato, then cut the planks into ½-inch batons.
How to Make // The Steps
I really enjoy sweet potato fries. The one trick to super-crisp sweet potatoes – a very hot oven. It is helpful if you preheat it for a bit before you put the sweet potatoes in.
- Put the sweet potato wedges into a large bowl. Add olive oil and sea salt. Toss and coat completely.
- Line a baking sheet (or two) with tin foil or parchment paper. Lay the sweet potatoes out in a single layer. Bake in a preheated 475-degree oven for 25 to 30 minutes. It really depends on how thick your fries are.
- Meanwhile, line a cake pan with tin foil. Arrange marshmallows in a single layer.
- Add the marshmallows to the oven with the sweet potatoes. Cook until the marshmallows begin to puff and toast, about 5 minutes. Next time, I will go darker, I loved the toasted flavor in the sauce and think that it could be even more pronounced.
- Add the heavy cream and marshmallows to a blender. The marshmallows are super sticky, so I just scraped off as much as I could. Blend until smooth. Add more cream if you need to thin the dip out.
- Take the fries out of the oven. Check for seasoning, and add more salt if needed. Serve with toasted marshmallow dip.
What Makes These Sweet Potato Fries with Marshmallow Dip So Good?
I am a sweet potato fiend. I adore them in just about which way. But this combines both salty and sweet flavors for a side dish I make time and time again because:
- A super hot oven and space between the fries bake sweet potatoes to crisp and tender every time.
- The toasted marshmallow dip is so easy and absolutely divine.
- My kids love it and it makes a wonderful appetizer or side dish for any occasion.
Serving Suggestions
The baked sweet potato fries and marshmallow dipping sauce are best served right away.
Dip Tip: As the dip cools, the marshmallow begins to harden. If this happens, just put it back in the blender with a splash of milk or cream and it will smooth out again.
Top Tips for Baked Sweet Potato Fries with Marshmallow Dipping Sauce:
- Make sure the oven is super hot. I like to preheat the oven way ahead of time before I even start prepping the recipe.
- Use more than one baking sheet, if necessary. The sweet potato fries need 1-2 inches of space between each piece. This ensures the hot air in the oven can reach all sides of the potato for the ultimate crisp exterior.
- Use aluminum foil or parchment-paper. Keep in mind that aluminum foil conducts heat more efficiently, which means deeper, darker sweet potatoes and marshmallows.
- Toast the marshmallows to pale, golden brown or charred. I kept it at a happy, golden-brown medium, which took about 5 minutes in my oven. Keep the marshmallows in the oven longer for a deeper, toasty flavor.
- Serve immediately. The fries and marshmallow dip are best when served straight away. If the marshmallow sauce tightens up, simply put it back in the blender with a splash or milk or cream or re-whip by hand.

Did you really make fluff DIP? My goodness, I love you.
Yes, yes I did. 🙂
Oh! I just died! Potatoes and mallow combination? Divine! Thanks a lot for the recipe. Gotta head to my kitchen and start making one^^
You are welcome! Hope that you like it.
While my boys described the chocolate yogurt bread as epic yummmm….I am using it here. Oh my….hello marshmallow dip…this could be a lovely friendship!!
Wow. That is quite a compliment! Tell the boys thank you. 🙂
When I roast sweet potato chunks for my kids, they call them sweet potato candy because they are so sweet. While I don’t get them as crisp as with regular homemade fries, I do manage to get a nice crust! I’ve found that if I throw in a little extra oil, so you have about a quarter-half an inch of oil in the pan, it helps. Not the healthiest, but makes for a nice, firm exterior. Good luck and I can’t wait to try this!
Thank you for the tip! I will try that next time.
One thing that I do to get sweet potato fries a little crispier is to place them on an oven cooling rack, and place that on top of a cookie sheet. That way there is a lot less surface area touching the fries, unlike simply placing them on a cookie sheet. hope this helps!
that is a great idea too Rachael, I will try that next time.
My favorite dip for sweet
potato fries is a mix of buttery maple syrup and mayo lile a 2 to 1 maple to mayo u will never know mayo is in it and its prolly the best dip ive ever had with swt potato fries soo i am looking forward to trying this dip
This dip looks like the best thing ever created…and so easy! 😀 You are a genius Bree, a genius.
I cannot take the credit for this one, I got it from a restaurant that I really like. But thank you!
Goodness gracious… turning one of my favorite sides into a pseudo-dessert. I think, yes. I will be dreaming of roasted marshmallows all day! 🙂
Me too! I loved making this. I knew that it would be good, but it is also really fun.
What a fantastic idea – a “sweet” dip to go along with the sweet potatoes. I’ve always had mine with ranch, but this sounds so much better. Thank you 🙂
It was just a fun change of pace. My kids really liked it. Its fun.
This dip is too brilliant, and is perfect for sweet potato fries. I love this!
thank you Cassie!
Are you KIDDING ME?!?!?! Heading to the store now for marshmallows….my kids will FLIP over this! Thanks, Bree! Looks like another winner!
Not kidding! I hope that they loved them!
Sweet potato fries should be presented that way every time – it just brings so much more to the experience. I admit, if you slapped a big burger in the dish with the fries, I’d be the happiest woman on the planet. The marshmallow dip just tickles me – looks like the perfect accompaniment and I love that you made it in your vitamix…the fact that I can whip up the dip in the vitmaix is reason alone to make your recipe. Thanks!
I tickled me too. When I figured out what it was, I was sold. So fun!
Love sweet potato fries! I too have had a hard time getting them perfectly crispy without frying them. What’s funny is, I just made these the other day but with a strawberry dipping sauce. I guess great minds think alike! 🙂
Even fried, I don’t think that they crisp like a french fry. But I still love them. Yum, strawberry dipping sauce sounds so good for these.
I soak the sweet potato strips in ice water for a few hours before cooking. I swear it helps to make them crispier.
Thanks! I’ll try it next time.
This sounds amazing! I also love taco seasoning on my sweet potato fries but I can see how you’d want to go the plain route for the dip.
Taco seasoning on sweet potatoes is insanely good.
Toasted marshmallow dip? That sound fabuloso!
It is! A treat for sure, but so fun.
I have been craving sweet potato fries lately and these will definitely hit the spot!
These were so fun. I loved making them and I loved eating them.
Love this! It’s like a deconstructed, fried sweet potato casserole!
that is exactly what it is like. I wish that I came up with this idea all on my own.
Crazy combi, but I imagine how it will tastes.. Delicious!
I know! I was shocked at how amazing it was.
This is brilliant! My oldest says he doesn’t like sweet potatoes but I bet he would eat them with marshmallow dip!
Wouldn’t you? Hope that he turns around. 🙂
These look super delicious!
They are June! My kids loved them.
I hope that you so Meredith.
Those look delicious! I never would have thought that combination worked together but I’ll have to try it. Sweet potato fries are my absolute favorite! Thank you for introducing me to Michelle Kane’s Photoshop actions! I cannot get enough of them! I can’t imagine not having them!!
I love her actions! You are welcome. I just got the new set, and they are gorgeous!
If you use vegetable oil instead of olive oil, it’ll get hotter and the fries will crisp better
Duh! Why didn’t I think of that! Thanks Eno!
I tried this recipe today and my marshmallows were sooooo sticky. I made a huge mess in my kitchen, but the dip turned out delicious. 🙂
It can be, but worth it!
My husband and I go there just for the sweet potatoes and this dip. LOVE IT! We went last weekend, and were talking about how we could mimic this recipe. I was afraid to ask, thinking they would not tell me their recipe. So glad you asked and shared with the rest of us. I am going to go buy sweet potatoes now and make this sauce. You don’t know how excited I am. HEHEHE. 🙂
How funny! I hope you love it as much as theirs.
how was the cleanup of the blender? lol. the sauce sounds amazing.
I’m actually going to line a 9×13 baking dish with Graham cracker crust, pour a brownie mix over that and then drizzle with this sauce over it when it comes it if the oven for a more gourmet s’more.
thanks!
Not bad. Lots of hot water. Marshmallow is not hard to get clean because their is no fat in it.
Super yummy! I toasted the marshmallows for longer as you suggested, and i could totally taste it! Thanks for the recipe!
You are very welcome.
