Make It Your Way

This Sweet Potato Fries with Toasted Marshmallow Dip Recipe is truly a canvas for your creativity. Whether you want to tweak the flavors for a dietary need or add a little seasonal twist, it’s all about making this dish your own.

Variation: For a vegan spin, I swapped the heavy cream for coconut cream and used vegan marshmallows. It gave the dip a lovely tropical undertone that paired surprisingly well with the natural sweetness of the fries.
Spicy Kick: If you crave a bit of heat, sprinkle cayenne or smoked paprika on your fries before baking. The smoky spice cuts through the sweetness beautifully.
Seasonal Twist: During fall, I add a pinch of cinnamon or nutmeg to the fries’ olive oil toss for an aromatic touch that complements the toasted marshmallow dip perfectly.

Step-by-Step: How I Make Sweet Potato Fries with Toasted Marshmallow Dip Recipe

A round white bowl filled with light beige dipping sauce is placed on a soft grey cloth on a white marbled surface. Around the bowl, there are several long, thin, slightly burnt orange sweet potato fries with darkened edges. Two fries are dipped into the sauce, standing upright. In the top left corner, a white bowl lined with white parchment paper holds more sweet potato fries. photo taken with an iphone --ar 2:3 --v 7

Step 1: Prep Your Sweet Potatoes for Crispy Perfection

Start by peeling and cutting 4 sweet potatoes into evenly sized sticks. Uniform pieces are key to baking them to crispy perfection. Toss the fries thoroughly in 3 tablespoons of olive oil and a generous pinch of sea salt—don’t be shy here! Each fry should be fully coated, ensuring every bite has that perfect balance of savory and crispy texture.

Step 2: Arrange and Bake with Care

Line one or two baking sheets with tin foil or parchment paper for easy cleanup and to prevent sticking. Spread the sweet potato fries out in a single layer—crowding them will cause steaming, not crisping! Pop them into a preheated oven at 475°F. Bake for about 30 minutes, but keep an eye because thinner fries may cook faster while thicker ones might need those full 30 minutes to get beautifully golden and crisp.

Step 3: Toast the Marshmallows Just Right

While your fries are baking, line a cake pan with tin foil and arrange about half a bag (roughly 7 ounces) of marshmallows in a single layer. Slide them in the oven alongside the fries for about 5 minutes. Watch carefully as they puff up and start to toast. A golden brown hue is perfect here, but feel free to leave them in a bit longer next time if you want a stronger, smokier flavor.

Step 4: Whip Up That Creamy Marshmallow Dip

Remove the toasted marshmallows carefully and transfer them to a blender. Add ½ cup of heavy cream. Since marshmallows can get sticky, scrape any toasted bits off the pan right into the blender to capture all that extra flavor. Blend until silky smooth and creamy. If the dip feels too thick, simply add a little more cream until it reaches your ideal dipping consistency.

Step 5: Final Touches and Serving

Pull those fries from the oven and give them a quick taste. Add a pinch more sea salt if needed to brighten up those flavors. Serve the fries hot and crispy alongside the luscious toasted marshmallow dip. The contrast between the savory, crispy fries and the sweet, creamy dip makes every bite an irresistible treat. Enjoy!

Top Tip

These tips will help you get those perfectly crispy sweet potato fries and a luscious toasted marshmallow dip every time. A few simple tricks make all the difference!

Uniform Cutting: I always cut the sweet potatoes into evenly sized sticks so they bake evenly and get that ideal crispness without burning or undercooking.
Watch the Marshmallows Closely: Toasting marshmallows in the oven happens fast! Keep a careful eye to catch them when they’re just golden and puffed for the best flavor without burning.
Use Parchment Paper: Lining your baking sheets with parchment paper prevents sticking and makes cleanup a breeze — a must-have for sticky marshmallow dip prep.
Adjust Cream Gradually: When blending your marshmallow dip, add heavy cream slowly. It’s easy to thin the dip out, but hard to thicken it if you add too much at once.

Garnishes

A sprinkle of fresh chopped rosemary or a pinch of smoked paprika on the fries adds a wonderful aroma and a subtle smoky kick. For the toasted marshmallow dip, top it with a few mini toasted marshmallows or a light dusting of cinnamon for an inviting, cozy touch.

Side Dishes

These sweet potato fries with toasted marshmallow dip pair beautifully with savory mains like grilled chicken, BBQ ribs, or even a fresh green salad with a tangy vinaigrette to balance the sweetness. For a fun twist, add some spicy coleslaw on the side to complement the creamy dip.

Make Ahead and Storage

Storing Leftovers

Store any leftover sweet potato fries and toasted marshmallow dip separately in airtight containers in the refrigerator. The fries will stay fresh for about 2 to 3 days, while the dip can keep up to 3 days as well.

Freezing

While the fries can be frozen if placed on a single layer on a baking sheet first and then transferred to a freezer-safe bag, the toasted marshmallow dip is not ideal for freezing due to its creamy texture—it may separate upon thawing.

Reheating

To reheat the fries and bring back their crispiness, pop them in a preheated 425°F oven for 8-10 minutes. Avoid the microwave, which makes them soggy. Warm the marshmallow dip gently in a small saucepan over low heat, stirring constantly to prevent scorching.

Frequently Asked Questions:

Can I use regular potatoes instead of sweet potatoes for this recipe?

You can use regular potatoes, but keep in mind the flavor and sweetness will be different. Sweet potatoes add a natural sweetness that complements the toasted marshmallow dip wonderfully.

How long should I watch the marshmallows when toasting?

Marshmallows toast quickly at 475°F — usually around 5 minutes. Keep a close eye so they puff up and turn golden brown without burning.

Can I make the toasted marshmallow dip vegan?

Absolutely! Substitute heavy cream with coconut cream and use vegan marshmallows to keep the dip creamy and delicious without animal products.

What’s the best way to get crispy fries without frying?

Baking at a high temperature (475°F) and spacing the fries out in a single layer on parchment paper helps achieve a crispy exterior. Tossing them well in olive oil and salt also contributes to perfect crispness.
