Make It Your Way

One of the best things about the Sweet Potato Fries with Toasted Marshmallow Dip Recipe is how easy it is to customize to your taste and occasion. Whether you want to make it a bit more savory, dial up the sweetness, or fit your dietary needs, there’s plenty of room to play around.

Variation: For an extra crispy twist, I like to soak the cut sweet potatoes in cold water for 30 minutes before patting them dry and baking. It really makes the fries crisp up beautifully—and I never skip this step now.
Dairy-Free Option: Swap out the heavy cream in the dip for full-fat coconut milk to keep things creamy but dairy-free. The subtle coconut flavor pairs surprisingly well with the toasted marshmallows!
Less Sweet Dip: If you find the marshmallow dip a bit too sweet, try replacing half the marshmallows with cream cheese. It adds a tangy richness that balances the flavors nicely.
Seasonal Additions: Toss a sprinkle of cinnamon or smoked paprika on your fries before baking for a cozy fall vibe or a smoky kick.
Gluten-Free & Vegetarian: Just double-check your marshmallows are certified gluten-free and vegetarian-friendly to keep this recipe accessible for everyone at the table.

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

A small white bowl filled with smooth, creamy, light beige dipping sauce sits on a light gray cloth with a coarse texture. Around the bowl are several long, thin sweet potato fries, deep orange with dark brown crispy edges. Two fries rest inside the bowl, standing upright and partially dipped in the sauce, while more fries lay scattered nearby on the cloth and the white marbled surface beneath. In the top left corner, a white paper-lined white dish holds a pile of similar crispy sweet potato fries.

Step 1: Prep Your Sweet Potatoes

Start by peeling and cutting your sweet potatoes into sticks—aim for uniform thickness so they bake evenly. Toss them in a large bowl with 3 tablespoons of olive oil and a generous pinch of sea salt. Make sure each fry is well coated; this oil helps them crisp up beautifully in the oven.

Step 2: Spread and Bake

Line one or two baking sheets with tin foil or parchment paper. I prefer parchment for easier cleanup! Lay the sweet potato sticks out in a single layer—no overlapping, so they roast instead of steam. Bake in a 475°F oven for 25 to 30 minutes, depending on how thick your fries are. You’ll know they’re ready when they look golden and crispy on the edges but still tender inside.

Step 3: Toast Your Marshmallows

While the fries are baking, line a small cake pan or baking dish with tin foil. Spread half a bag of marshmallows in a single layer for even toasting. Pop them in the oven alongside the sweet potatoes for about 5 minutes or until puffed and golden. If you love a richer toasted flavor, leave them in a little longer until they turn a deeper brown.

Step 4: Blend Your Dip

Carefully transfer the warm toasted marshmallows to a blender. Add ½ cup of heavy cream and blend until everything becomes smooth and creamy. You might need to scrape down the sides a couple of times because marshmallows get super sticky! If the dip feels too thick, add a little more cream bit by bit until you reach your desired consistency.

Step 5: Season and Serve

Take your sweet potato fries out of the oven and give them a quick taste—add more sea salt if needed to bring out all their natural sweetness. Serve them warm with a generous bowl of that luscious toasted marshmallow dip on the side. Trust me, dipping these crispy, caramelized fries in a creamy, toasted marshmallow sauce is pure magic.

Top Tip

These little insider tips will make your Sweet Potato Fries with Toasted Marshmallow Dip Recipe even better — from extra crisp fries to a perfectly smooth dip, here’s what I’ve learned along the way.

Soak before baking: I always soak my cut sweet potatoes in cold water for 30 minutes before baking. It really helps remove excess starch and gives those fries an unbeatable crispiness!
Don’t overcrowd the pan: When baking the fries, spread them out evenly with space between each stick. Overlapping leads to steaming, which means softer fries instead of crispy ones.
Toast marshmallows longer for depth: I found that toasting marshmallows a bit longer until they’re a deeper golden brown adds a richer, more complex flavor to the dip.
Use parchment over foil: Switching to parchment paper prevents sticking and makes cleanup so much easier, saving you time and frustration.

Garnishes

To kick your presentation up a notch, sprinkle fresh chopped rosemary or thyme over the fries for a lovely herbal aroma that pairs beautifully with the sweet marshmallow dip. A little flaky sea salt on top just before serving enhances the crispiness and balances sweetness. For a fun touch, add a few toasted mini marshmallows on the dip bowl rim — it’s as cute as it is tasty!

Side Dishes

This dish shines as a snack or side, and it complements hearty meals perfectly. Try serving it alongside grilled chicken or turkey burgers for a casual dinner. It also works great paired with a crisp green salad tossed in a tangy vinaigrette, which cuts through the richness beautifully. For a cozy vibe, cheese-stuffed meatballs or a smoky black bean chili make excellent companions.

Make Ahead and Storage

Storing Leftovers

Keep any leftover sweet potato fries and toasted marshmallow dip in separate airtight containers in the refrigerator. The fries stay good for up to 3 days but may lose some crispiness. The dip remains creamy and delightful for about 2 to 3 days as well.

Freezing

While freezing fries can affect their texture, you can freeze leftover sweet potato fries in a single layer on a baking sheet, then transfer to a freezer bag for up to 1 month. The toasted marshmallow dip doesn't freeze well as it can become grainy, so I recommend making fresh dip each time for that perfect creamy finish.

Reheating

To revive leftover fries, reheat them in a preheated oven at 400°F for about 8–10 minutes to bring back their crisp edges. Avoid the microwave to keep them from getting soggy. For the dip, gently warm it on low in a small saucepan or microwave in short bursts, stirring in a splash of cream if it needs loosening up.

Frequently Asked Questions:

Can I make the sweet potato fries crispier?

Absolutely! Soaking the cut sweet potatoes in cold water for 30 minutes before baking helps remove starch and results in crispier fries. Also, baking at a high temperature of 475°F and making sure the fries aren’t crowded on the baking sheet helps them become perfectly crispy.

Is the toasted marshmallow dip very sweet? Can I make it less sweet?

The dip is naturally sweet due to the marshmallows. If you prefer a less sweet dip, you can reduce the amount of marshmallows or substitute half the marshmallows with cream cheese to add a tangy balance.

Can I prepare this recipe ahead of time?

You can prep the sweet potatoes in advance by cutting and soaking them ahead of time, but it’s best to bake the fries and prepare the dip fresh just before serving to enjoy optimum crispiness and creamy dip texture.

Are these fries and dip gluten-free and vegetarian?

Yes! This recipe is vegetarian. To ensure it's gluten-free, double-check that the marshmallows you use are certified gluten-free and vegetarian-friendly, as some brands include gelatin or gluten-containing ingredients.
