Make It Your Way

One of the best things about this Sweet Potato Fries with Toasted Marshmallow Dip Recipe is how easy it is to make it your own. Feel free to play around with flavors and textures to suit your cravings or dietary needs!

Variation: I love adding a sprinkle of smoked paprika or a pinch of cayenne pepper to the fries before baking. It adds a wonderful smoky kick that balances the sweetness beautifully.
Diet-Friendly: For a lighter dip, try swapping the heavy cream for half-and-half or even almond milk for a dairy-free twist. The texture will be a bit thinner but still delicious!
Seasonal Twist: During fall, I like to sprinkle some cinnamon and nutmeg on the fries after baking to enhance their natural warmth and sweetness.
Extra Crispiness: A tip I swear by is soaking the cut sweet potato sticks in cold water for 30 minutes before baking, then patting them dry — it really makes the fries crispier!

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. I like them about the size of traditional fries—not too thick, so they crisp up nicely. Toss them in a large bowl with 3 tablespoons of olive oil and a good sprinkle of sea salt. Make sure every fry is evenly coated. This helps with both flavor and that beautiful golden crisp.

Step 2: Arrange and Bake

Line one or two baking sheets with tin foil or parchment paper—parchment is my go-to to prevent sticking and make cleanup a breeze. Spread your coated fries out in a single layer without overcrowding. This is key to getting crispy edges. Preheat your oven to a sizzling 475°F, then pop the sheets in for 25 to 30 minutes. Keep an eye on them; you want tender interiors with a crisp surface.

Step 3: Toast Those Marshmallows

While your fries are roasting, prepare the marshmallows. Line a cake pan or small baking tray with tin foil and spread out about half a bag (roughly 7 ounces) of marshmallows in a single layer. Place them in the oven alongside the fries for about 5 minutes until they puff up and get that beautiful golden toasted top. If you love an even deeper caramelized flavor, leave them in a little longer—watching closely so they don’t burn.

Step 4: Blend Up Your Dip

When the marshmallows are toasted, transfer them to a blender or food processor along with ½ cup of heavy cream. Be prepared—they’re sticky, so scrape off as much as you can from the foil. Blend until smooth and creamy. If the dip feels too thick, add a little more heavy cream gradually until it’s just right for dipping those fries.

Step 5: Serve and Enjoy!

Pull the fries out of the oven and give them a quick taste test—sometimes a little extra sea salt is just perfect. Serve the hot, crispy fries alongside your luscious toasted marshmallow dip. The contrast of the sweet, crunchy fries with the rich, creamy dip creates an irresistible combo that's perfect for cozy gatherings or any time you want a fun twist on a classic side dish.

Top Tip

Getting the perfect texture and flavor balance in this Sweet Potato Fries with Toasted Marshmallow Dip Recipe really comes down to a few key details I've picked up along the way.

Soak and Dry: I always soak the sweet potato sticks in cold water for about 30 minutes before baking, then pat them completely dry. This step makes a noticeable difference in achieving crispiness without sacrificing tenderness.
Marshmallow Toasting Time: Through trial and error, I found toasting marshmallows just long enough to get a beautiful golden brown and puff really amps up that rich, smoky flavor in the dip without burning it.
Blending Technique: When blending the toasted marshmallows with the cream, scraping off any sticky bits clinging to the foil beforehand helps the blender run smoothly and creates a perfect smooth, creamy dip.
Don't Overcrowd the Pan: Giving those fries plenty of space on the baking sheet prevents steaming and keeps them from getting soggy—this little step ensures they come out crispy every time.

Garnishes

Sprinkle a little freshly chopped rosemary or thyme on the fries just before serving for an herbal aroma that complements the sweetness. A light dusting of smoked paprika on the fries also adds a subtle warmth. On the dip side, a tiny pinch of flaky sea salt or a few crushed graham cracker crumbs creates delightful texture and layers of flavor.

Side Dishes

This dish pairs beautifully with a crisp green salad dressed in a light vinaigrette to balance the sweet and rich notes. It also works as a fun side alongside grilled chicken or turkey burgers for a casual meal with a creative twist. For a cozy touch, roasted corn on the cob or sautéed green beans complete the plate wonderfully.

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 good for up to 3 days, while the dip keeps well for up to 2 days for best freshness and flavor.

Freezing

While the fries technically can be frozen, their texture tends to get a bit soggy after thawing, so I usually recommend enjoying them fresh. The marshmallow dip doesn't freeze well because the cream can separate. For best results, make the dip fresh when serving.

Reheating

To bring leftover fries back to life, reheat them in a 400-degree Fahrenheit oven for about 5–7 minutes to regain their crispiness without drying them out. Avoid microwaving the fries as they can turn mushy. Give the toasted marshmallow dip a quick stir before serving chilled or at room temperature.

Frequently Asked Questions:

Can I make the toasted marshmallow dip ahead of time?

Yes! You can prepare the dip a few hours ahead and store it covered in the refrigerator. Give it a quick stir before serving to restore its smoothness.

What can I substitute for heavy cream in the dip?

If you want a lighter version, you can use half-and-half or milk instead of heavy cream, but keep in mind the dip will be less rich and creamy.

How do I make the fries extra crispy?

Soaking the fries in cold water for at least 30 minutes before baking is a great tip to remove excess starch and helps them crisp up beautifully in the oven.

Can I use marshmallows other than plain white ones?

Plain white marshmallows work best for this recipe to keep flavors balanced, but you can experiment with flavored marshmallows if you want a unique twist. Just be mindful of added colors or flavors impacting the dip's taste.
