Side Dishes
This sweet potato with marshmallow cream recipe transforms humble sweet potatoes into a showstopping side dish with crispy edges and a gooey marshmallow center that tastes like holiday dessert.
The secret lies in roasting the potatoes until tender yet firm enough to hold their shape, then topping them with a silky marshmallow cream that caramelizes just enough to create that perfect contrast of textures.
I developed this recipe after years of perfecting the balance between tender potatoes and that irresistible marshmallow topping that always disappears first.
The magic happens in the oven where sweet potatoes roast until their edges develop a golden crispness while maintaining a creamy interior.
The marshmallow cream, made with just a few pantry staples, gets its signature texture from whipping egg whites to stiff peaks before folding in melted marshmallows and cream cheese.
This method ensures the topping stays light and airy rather than dense, creating that perfect pull-apart quality that makes every bite feel like a decadent treat.
What you'll end up with is a dish that looks as impressive as it tastes—crispy on top, tender inside, and topped with a glossy, caramelized marshmallow cream that's impossible to resist.
The sweetness of the marshmallows pairs beautifully with the earthy sweetness of the potatoes, creating a flavor combination that's both comforting and sophisticated. This recipe serves four and comes together in under an hour, making it perfect for holiday dinners, family gatherings, or even as a special weekend treat.
The best part? This dish requires just one pan for both the potatoes and the marshmallow topping, which means less cleanup and more time enjoying the results.
Serve it warm with a sprinkle of cinnamon or a drizzle of honey for extra flair. Here's how to make it perfectly every time.

Sweet potatoes are the star here—orange-fleshed, firm varieties like Beauregard hold their shape best. Trader Joe's and Walmart usually have them pre-peeled for convenience, but I always peel mine myself (the skin can get tough when roasted). For the marshmallows, Kraft Jet-Puffed or Dandies melt perfectly without getting gummy. The cream cheese? Philadelphia brand is my go-to—it whips smoother than store brands. Pro tip: let everything sit at room temperature for at least 30 minutes before starting, especially the egg whites and cream cheese—they whip up so much better when they're not cold.
No marshmallows? Melted white chocolate chips work in a pinch (reduce by half), though they won't caramelize the same way. Short on egg whites? Aquafaba (chickpea brine) works at a 1:1 ratio—just whip it longer. The honey drizzle is optional but adds a gorgeous glaze. If you're feeling fancy, swap the granulated sugar for turbinado sugar—it gives the marshmallows a subtle crunch. And if you're making this ahead, make the marshmallow cream first—it keeps in the fridge for up to 3 days, ready to bake whenever you are.
Roasted sweet potatoes keep in the fridge for 4-5 days if wrapped tightly in foil, but honestly, they're best eaten fresh. The marshmallow cream? Store it in an airtight container with parchment paper between layers—it'll last 3 days in the fridge. For make-ahead magic, assemble the whole dish (potatoes + cream) and refrigerate overnight, then bake straight from the fridge (add 10-15 minutes to the baking time). The flavor actually deepens after a night in the fridge—trust me on this. Leftovers? They're rare, but if you have any, reheat them gently in the microwave with a splash of water to keep the marshmallow from drying out.

Step-by-step instructions for sweet potato with marshmallow cream
Here's how to create that perfect crispy exterior and gooey marshmallow center—no fancy skills needed.
Prep the Sweet Potatoes for Perfect Crispiness
Preheat your oven to 425°F and line a large baking sheet with parchment paper. Peel the 4 whole large sweet potatoes and slice them lengthwise into ½-inch thick rounds. For even cooking, I like to trim any uneven edges with a knife so all slices are consistent in thickness.
Brush each slice generously with ½ cup melted unsalted butter, making sure to get every surface. This butter creates that golden, crispy crust while keeping the inside moist. Arrange the slices on the prepared baking sheet in a single layer, leaving about ½ inch between each piece—they'll expand as they bake.
Bake Until Golden and Tender
Place the baking sheet in the preheated oven and bake for 20-25 minutes, flipping the slices halfway through cooking. You're looking for slices that are golden brown on top and fork-tender when pierced—they should slide off your knife easily but still hold their shape.
Here's the thing—don't overbake. Sweet potatoes continue cooking after you remove them from the oven, and you want that perfect balance between crispy exterior and tender interior. If they're browning too quickly, tent the pan with foil for the last 5 minutes of baking.
Whip the Marshmallow Cream Filling
While the sweet potatoes bake, beat the 4 whole large egg whites in a medium bowl until they form soft peaks. In a separate bowl, mix the 8 oz softened cream cheese, 2 cups large marshmallows, ¼ cup granulated sugar, 1 tsp ground cinnamon, and ½ tsp sea salt until completely smooth and creamy.
Gently fold the marshmallow mixture into the egg whites using a spatula, being careful not to deflate the whipped egg whites. For extra creaminess, you can add the ¼ cup heavy cream at this stage. The mixture should be thick but still pipeable—if it's too stiff, add a few more spoonfuls of whipped egg whites to loosen it.
Assemble and Bake to Gooey Perfection
Once the sweet potatoes are done baking, remove them from the oven and let them cool slightly for 3-5 minutes. Spread about ¼ cup of the marshmallow cream mixture onto each slice, creating an even layer. Place the slices back in the oven and bake for an additional 10-12 minutes at 350°F until the marshmallow topping is fully melted and golden.
Watch closely during this final stage—the marshmallow should be bubbly and just starting to caramelize on top. If it browns too quickly, cover loosely with foil for the last 2-3 minutes. The center should remain soft and gooey, not firm.
Finish with Cinnamon, Honey, and Serve Warm
Remove the sweet potatoes from the oven and immediately dust the tops generously with 1 tsp ground cinnamon. For that extra touch, drizzle each slice with 1 tbsp honey and let it pool slightly on top. Serve warm, straight from the oven, for the ultimate experience.
This dish is all about contrast—the crispy, caramelized top gives way to the soft, marshmallow-infused center with every bite. The cinnamon and honey add that perfect balance of sweet and warm spices. Enjoy immediately while the marshmallow is still gooey and the sweet potatoes are piping hot!
Pro Tips For Making Sweet Potato With Marshmallow Cream
- PIERCE THE POTATOES: Cut your sweet potatoes lengthwise first, then slice into ½-inch rounds—this keeps them from curling up while roasting and guarantees even cooking. I learned this the hard way when my first batch turned out warped and uneven.
- SALT THE WATER: Boil your sweet potato slices in salted water (1 teaspoon per quart) for 5 minutes before roasting—this jumpstarts the softening and prevents them from drying out later. Yes, even if you’re skipping the boil step, this small move makes a real difference.
- WHISK THE CREAM CHEESE: Softened cream cheese and egg whites blend best when you whisk them together over warm water (or in short bursts in a stand mixer) until completely smooth. Lumps in your marshmallow cream are a dead giveaway you didn’t mix it enough—no one wants to scrape them off their plate.
- TOAST THE MARSHMALLOWS: Spread whole marshmallows on a baking sheet and toast them in a 350°F oven for 3–4 minutes before blending into the cream. This caramelizes their edges slightly, adding depth of flavor without burning them—trust me, your dish will taste richer.
Wine and beer pairings for this sweet potato with marshmallow cream
Sweet Wine Pairings
For this dessert-like side dish, opt for Moscato d'Asti—its light sweetness and effervescence complement the marshmallow cream beautifully. The bubbles cut through the richness while the subtle fruitiness enhances the caramelized sweet potatoes. I always keep a bottle of La Gioiosa Moscato d'Asti on hand for these occasions. 🍷
A Riesling with a touch of residual sugar, like Dr. Loosen Blue Slate, works wonderfully too. Its crisp acidity balances the dish's sweetness while its floral notes harmonize with the cinnamon and honey. Chill your wine to 45-50°F for optimal enjoyment.
Rich Dessert Wines
If you prefer something bolder, a Port-style wine like Taylor's Late Bottled Vintage adds depth to the marshmallow flavors. The nutty, caramel undertones mirror the roasted sweet potatoes, creating a luxurious pairing. Serve slightly chilled (55-60°F) to let the wine's complexity shine.
Beer Pairings
A honey wheat beer like Allagash Honey Beer is my go-to for this dish. The honey notes echo the drizzle while the light body prevents the marshmallow cream from feeling overwhelming.
For a darker option, try a Belgian dubbel like Westmalle Dubbel—its caramel and spice notes complement the cinnamon beautifully. 🍺
Non-Alcoholic Options
Don't overlook sparkling apple cider—it's a fantastic non-alcoholic choice. Brands like Martinelli's Sparkling provide that same refreshing contrast without alcohol. For a more sophisticated option, a ginger-infused sparkling water with a splash of cranberry juice adds a zesty kick that cuts through the sweetness.

Frequently asked questions
Can I make this recipe with regular potatoes instead of sweet potatoes?
Sweet potatoes are essential for this dish—their natural sweetness and moist texture pair perfectly with the marshmallow cream. Regular potatoes would be too starchy and dry after roasting, and they lack that caramel-like flavor. If you're looking for a similar texture, try yams, but they're harder to find and less flavorful. Stick with sweet potatoes for the best results!
What if my marshmallow cream turns out too thick or too runny?
If your marshmallow cream is too thick, add 1-2 tablespoons of whipped egg whites to lighten it up. For a runny consistency, fold in 1 tablespoon of softened cream cheese to thicken it. The key is to maintain that perfect balance—it should be thick enough to hold its shape when spread but still creamy and spreadable. Adjust gradually while mixing!
Can I prepare this dish ahead of time?
Make the marshmallow cream up to 3 days ahead and store it in an airtight container in the fridge. For the sweet potatoes, roast them up to 2 days ahead and reheat in the oven at 350°F for 10 minutes before adding the marshmallow cream. Assemble and bake fresh before serving for the best texture. The flavors actually deepen overnight!
Why did my marshmallow topping burn before it melted?
Marshmallows burn easily because sugar caramelizes quickly. Keep a close eye on them during the final 10-12 minutes of baking and reduce the oven temperature to 325°F if needed. Cover loosely with foil for the last 2-3 minutes to slow browning while still allowing it to melt. The topping should be bubbly and golden, not dark brown!
Can I use store-bought marshmallow cream instead of making it from scratch?
You can, but homemade marshmallow cream gives you that perfect light, airy texture and customizable sweetness. If you're short on time, look for a high-quality marshmallow fluff (like Jet-Puffed) and mix it with 2 oz softened cream cheese and 1 tsp cinnamon for a quick substitute. The flavor won't be identical, but it'll still taste delicious!
