Ingredients & Why They Work
For this recipe, it’s all about keeping it straightforward but important to pick fresh, quality ingredients. Sweet potatoes should be firm and vibrant, and for the marshmallow dip, I always recommend fresh marshmallows for that perfect toasting effect.

- Sweet potatoes: Naturally sweet and sturdy, they crisp nicely in the oven and hold up well to dippings.
- Olive oil: Helps to get those fries perfectly golden and crispy without weighing them down.
- Sea salt: Just the right touch to bring out the natural sweetness of the fries.
- Marshmallows: When toasted, they add a creamy, caramelized flavor to the dip that’s pure nostalgia.
- Heavy cream: Creates a rich, smooth dip that balances the sweetness and adds luscious texture.
Make It Your Way
One of the best parts about this Sweet Potato Fries with Toasted Marshmallow Dip Recipe is how easy it is to tailor it to your taste buds or dietary needs. Don't hesitate to put your own spin on it — cooking should be fun and personal!
- Variation: For a vegan twist, swap the heavy cream for coconut cream and opt for vegan marshmallows. I’ve tried this version, and it still delivers that creamy, sweet dip without compromising on flavor.
- Spice it up: Toss your fries with a pinch of smoked paprika or cayenne pepper before baking for a smoky, slightly spicy kick that contrasts beautifully with the sweet dip.
- Seasonal swap: In the fall, try adding a sprinkle of cinnamon or nutmeg to the fries before baking to echo cozy autumnal flavors.
- Make it lighter: If you prefer a lighter dip, reduce the olive oil used on the fries or use less heavy cream in the dip and thin it a bit with a splash of almond milk.
Step-by-Step: How I Make Sweet Potato Fries with Toasted Marshmallow Dip Recipe

Step 1: Prep Your Sweet Potato Fries
Start by peeling and cutting 4 sweet potatoes into sticks—make sure they're relatively even in size so they bake uniformly. Toss your cut fries in a large bowl with 3 tablespoons of olive oil and a generous sprinkle of sea salt. Don’t be shy about coating each piece well; that olive oil is the secret to getting that coveted crispy exterior.
Step 2: Get Ready to Bake
Line one or two baking sheets with tin foil or parchment paper. I personally prefer parchment because it helps with crispiness and cleanup is a breeze. Spread the sweet potato fries out in a single layer, making sure none overlap — giving each fry ample space is key to baking them nice and crispy.
Step 3: Bake the Fries at High Heat
Preheat your oven to a blazing 475 degrees Fahrenheit. Slide your trays in and bake the fries for about 30 minutes. Check around the 25-minute mark if your fries are thinner; you’re looking for fries that are tender inside with crisp edges. Flip them halfway through for the best texture.
Step 4: Prepare and Toast the Marshmallows
While the fries are baking, line a small cake pan with tin foil and arrange about half a bag of marshmallows (approximately 1 cup) in a single layer. Add the pan to the oven alongside the fries about 5 minutes before they’re done. Watch closely as they puff up and toast to a lovely golden brown. For an even deeper toasted flavor, you can leave them in a little longer, but be careful — marshmallows burn quickly!
Step 5: Blend the Dip
Transfer the toasted marshmallows to a blender, scraping off as much as you can since they’re sticky. Add ½ cup of heavy cream and blend until silky and smooth. If the dip feels too thick, just add a splash more cream and blend again. You want a luscious dip that’s easy to scoop with your fries.
Step 6: Finish, Season, and Serve
Your sweet potato fries should be perfectly crispy now. Give them a quick taste and add more sea salt if needed. Plate your fries alongside a bowl of the warm, creamy toasted marshmallow dip and dig in. This combo is a guaranteed crowd-pleaser with its unique balance of sweet and savory.
Top Tip
These tips come from lots of experimenting in my kitchen to make sure your Sweet Potato Fries with Toasted Marshmallow Dip Recipe comes out perfectly every time!
- Slice Evenly: Cutting your sweet potatoes into sticks of similar thickness ensures they bake evenly and crisp up beautifully without burning.
- Use Parchment Paper: I’ve found that parchment paper makes cleanup a breeze and helps the fries develop a crispier outside compared to foil.
- Watch the Marshmallows Closely: Marshmallows can go from toasted to burnt in seconds. Keep an eye on them during roasting to get that perfect golden-brown color and deeper flavor.
- Don’t Skip the Salt: Salt is key for balancing the natural sweetness of the fries and dip, so taste and adjust before serving.
How to Serve Sweet Potato Fries with Toasted Marshmallow Dip Recipe

Garnishes
To add a little extra something, sprinkle chopped toasted pecans or a light dusting of smoked paprika over the fries for a smoky kick. A drizzle of honey or a little fresh rosemary can also complement the sweet and savory balance beautifully.
Side Dishes
This recipe pairs wonderfully with simple green salads, roasted chicken, or even a creamy coleslaw. For a fun twist, try serving alongside grilled corn on the cob or spicy black bean burgers to make a hearty vegetarian meal.
Make Ahead and Storage
Storing Leftovers
Once cooled, store leftover sweet potato fries in an airtight container in the refrigerator for up to 3 days. Keep the toasted marshmallow dip in a separate sealed jar or container to preserve its creamy texture.
Freezing
You can freeze the cooked fries by flash freezing them on a baking sheet first, then transferring to a freezer-safe bag or container. They’ll keep well for up to 1 month. The marshmallow dip is best fresh, so I don’t recommend freezing it.
Reheating
Reheat the fries in a 400-degree Fahrenheit oven for 5–10 minutes to regain crispiness. Avoid microwaving as it makes fries soggy. For the dip, briefly stir and let it come to room temperature before serving; if needed, whisk gently to restore its smooth texture.
Frequently Asked Questions:
Yes! While this recipe shines with sweet potatoes’ natural sweetness, regular potatoes will work too. Just note the flavor will be different, and the marshmallow dip pairs uniquely well with sweet potato’s natural sugars.
The marshmallow dip is vegetarian but not vegan in this recipe, since it uses heavy cream and regular marshmallows which often contain gelatin. For a vegan version, substitute heavy cream with coconut cream and use vegan marshmallows.
Using parchment paper, slicing fries evenly, and baking at a high temperature of 475°F for the full 30 minutes helps achieve crispiness. Avoid overcrowding the pan so each fry crisps rather than steams.
While you can prepare the dip ahead, it’s best served fresh for optimal creaminess and flavor. If making in advance, store it tightly sealed in the fridge and gently reblend or whisk before serving.
Final Thoughts
I hope this Sweet Potato Fries with Toasted Marshmallow Dip Recipe brings a fun, comforting twist to your next meal or snack time. It combines crispiness with creamy sweetness in such a delightful way – a perfect crowd-pleaser. So grab those sweet potatoes, warm up your oven, and enjoy every bite with that irresistible toasted marshmallow dip. Happy cooking and happy dipping!
