Sweet potatoes: I prefer fresh, firm sweet potatoes peeled and cut evenly to ensure they bake perfectly crisp.
Olive oil: It helps crisp the fries while adding a mild fruity note that complements the natural sweetness.
Sea salt: For that essential seasoning boost — it balances the sweet and savory elements beautifully.
Marshmallows: Using about half a bag gives plenty of gooey sweetness for the dip without overpowering.
Heavy cream: Adds richness and smooths out the toasted marshmallows into a silky dip texture.

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 adapt to your taste or the occasion. Whether you're craving something a little more savory or want to amp up the sweetness, there are plenty of ways to make this dish truly your own.

Spicy Kick: I love adding a pinch of smoked paprika or cayenne pepper to the sweet potatoes before baking for a smoky, spicy contrast to the sweet, creamy dip. It really wakes up the flavors!
Herb Infusion: Toss the fries with some fresh rosemary or thyme alongside the olive oil and salt. It adds a lovely earthy aroma that complements the sweetness without overpowering it.
Dairy-Free Dip: To make the dip vegan, swap the heavy cream for full-fat coconut milk. The marshmallow dip stays rich and luscious with a subtle coconut undertone.
Seasonal Twist: In fall, try sprinkling some cinnamon or nutmeg into the dip for an extra cozy vibe. It pairs beautifully with the toasted marshmallow flavor.
Chunky Dip: If you prefer texture, pulse the marshmallow and cream mixture briefly in the blender so you still have little toasted marshmallow bits throughout the dip. It adds a fun touch when dunking fries.

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 and Coat Your Sweet Potatoes

Start by peeling and cutting 4 sweet potatoes into sticks that are roughly the same size so they bake evenly. Toss them in a large bowl with 3 tablespoons of olive oil and a good sprinkle of sea salt. Make sure each fry is thoroughly coated—you want that oil to help them crisp up in the oven. This step sets the stage for irresistibly crunchy fries with tender centers.

Step 2: Spread and Bake to Perfection

Line one or two baking sheets with tin foil or parchment paper to prevent sticking and make cleanup easier. Lay your sweet potato sticks out in a single layer, leaving space between them—overcrowding causes sogginess. Then, pop the fries in your preheated oven at 475°F. Bake for about 30 minutes, but keep an eye on them if your fries are thinner or thicker. You want crisp outsides with tender, fluffy insides. The smell alone will have you eagerly waiting!

Step 3: Toast Your Marshmallows Alongside

While your fries are baking, line a small cake pan with tin foil and arrange about half a bag (around 7 ounces) of marshmallows in a single layer. Place the pan in the oven alongside the fries for roughly 5 minutes—or until you see the marshmallows puff up and develop a lovely toasted golden top. I personally love going a little darker for a richer smoky note, but watch closely—they can burn quickly.

Step 4: Blend Up the Creamy Toasted Marshmallow Dip

Transfer the toasted marshmallows into a blender and add ½ cup of heavy cream. Use a spatula to scrape off any sticky, toasted bits from the pan and add those in too—they boost the dip’s flavor big time. Blend until the mixture is smooth and creamy. If the dip feels too thick, simply add a little more cream until you reach the perfect dipping consistency. This luscious dip is the perfect sweet counterpart to your salty fries.

Step 5: Season & Serve It Warm

Once your fries are out of the oven, give them a quick taste test. Add more sea salt if needed to balance the flavors. Serve the fries while still warm alongside generous dollops of your toasted marshmallow dip. It’s a comforting, surprising combo that’s sure to delight everyone around your table!

Top Tip

These tips will help you get the crispiest, most flavorful sweet potato fries paired perfectly with the luscious toasted marshmallow dip. A few little tricks from my own kitchen adventures make all the difference!

Perfect Crispiness: Toss your fries thoroughly with olive oil and spread them out in a single layer without overcrowding. This ensures every fry gets that golden, crispy edge instead of steaming in the oven.
Watch the Toasting: Keep a close eye on the marshmallows as they toast. They can go from perfectly golden to burnt in seconds, so I suggest checking them after 4 minutes and adjusting based on your oven.
Smooth Dip Texture: Use a blender to puree the toasted marshmallows with heavy cream. If your dip feels too thick, add a splash more cream so it becomes smooth and easy for dipping.
Season at the End: Salt your fries well after baking. It’s tempting to add it all upfront, but sprinkling sea salt right after they come out of the oven gives you better control and a fresher flavor punch.

Garnishes

To elevate your sweet potato fries, consider garnishing with a sprinkle of finely chopped fresh rosemary or thyme for an herbal touch. A light dusting of smoked paprika adds a subtle smoky flavor that pairs surprisingly well with the sweetness. For the dip, a small drizzle of melted dark chocolate or a few crushed graham crackers sprinkled on top can bring a delightful s’mores-inspired flair.

Side Dishes

This Sweet Potato Fries with Toasted Marshmallow Dip Recipe is fantastic alongside a crisp green salad dressed with tangy vinaigrette to cut through the richness. It also pairs beautifully with grilled chicken or smoky BBQ ribs if you want to build a comforting meal. For a vegetarian feast, serve it with a hearty black bean burger or roasted vegetable skewers to keep things balanced yet exciting.

Make Ahead and Storage

Storing Leftovers

Store any leftover sweet potato fries and toasted marshmallow dip separately in airtight containers. The fries will keep well in the refrigerator for up to 3 days. The dip can also be refrigerated for about 2 to 3 days; just give it a quick stir or gentle reblend before serving again.

Freezing

If you want to freeze your sweet potato fries, lay them out on a baking sheet in a single layer and freeze until solid before transferring to a freezer-safe bag. This helps prevent them from sticking together. They’ll keep well for up to 1 month. The toasted marshmallow dip, however, doesn’t freeze well because of its texture—it's best enjoyed fresh.

Reheating

To reheat the fries and keep them crispy, pop them on a baking sheet and warm in a 400°F oven for about 8-10 minutes. Avoid microwaving, which tends to make fries soggy. For the dip, gently warm it in a microwave for 10-15 seconds and stir well, or let it come to room temperature and stir before serving.

Frequently Asked Questions:

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

Absolutely! While the recipe is designed for sweet potatoes to create that lovely sweet and savory balance, regular russet or Yukon gold potatoes would work nicely. Just keep in mind the baking time might need a slight adjustment depending on the potato variety and thickness of your fries.

What can I substitute for heavy cream in the marshmallow dip?

If you don’t have heavy cream on hand, full-fat coconut milk is a great alternative that will keep the dip rich and creamy. For a lighter option, you can try whole milk, but the dip might be a little less thick and luscious.

How do I prevent the marshmallows from burning in the oven?

Keep a close eye during those 5 minutes of toasting and place the pan on a rack further from the top heating element if possible. Marshmallows toast quickly, so checking around 4 minutes and pulling them out as soon as they’re puffed and golden will prevent burning.

Can I make the sweet potato fries and dip ahead of time?

Yes! You can prepare the fries and dip separately and store them in the refrigerator. Reheat the fries to crisp them back up before serving, and give the dip a quick stir or gentle blend to restore its smooth texture.
