Sweet Potato Pie With Marshmallow Meringue Recipe: Toasted Meringue Crown Over Silky Spice

This sweet potato pie with marshmallow meringue recipe delivers the perfect balance of spiced filling and cloud-like meringue—each bite is a harmonious blend of warm cinnamon and toasted marshmallow sweetness.

The secret lies in a velvety, well-seasoned filling that bakes to silky perfection, crowned with a golden meringue that puffs into a crisp, toasted finish. I’ve perfected this technique over years of holiday baking, ensuring the pie emerges with a crackly top and no soggy bottoms.

The foundation starts with a homemade pie crust—flaky and sturdy enough to hold the filling without shrinking, paired with a filling that’s smooth yet rich with cinnamon, nutmeg, and just the right amount of brown sugar.

The meringue, made with egg whites and marshmallows, transforms into a toasted crown when baked at high heat, creating that signature restaurant-quality texture. Every step—from mixing the filling to whipping the meringue—is designed to avoid common pitfalls like weeping or overbaked crust.

By the time you pull this pie from the oven, you’ll have a dessert that looks as impressive as it tastes: a golden, crackly meringue hiding pockets of gooey marshmallow, all resting on a spiced sweet potato filling that’s creamy yet firm.

The contrast of temperatures—warm filling, cool meringue—makes each forkful unforgettable. This is the pie that becomes the centerpiece of every holiday table, and it’s easier to achieve than you’d think.

Whether you’re baking for Thanksgiving, Christmas, or just a cozy dessert night, this recipe scales beautifully and delivers restaurant-quality results every time. The key is patience—letting the filling cool slightly before adding the meringue and baking at the right temperature to ensure that perfect toasted finish.

Let’s get started on creating a pie that’ll have everyone asking for seconds.

Ingredients for sweet potato pie with marshmallow meringue

Sweet potato pie magic starts with these 15 ingredients—rich filling meets toasted meringue perfection.

The sweet potatoes are non-negotiable—organic russets from Whole Foods or your local market have better flavor. Peel them first, then boil until fork-tender. For the meringue, room-temperature eggs whip up lighter. I always grab Kirkland Signature marshmallows—they’re uniform and melt beautifully. The butter matters too: Plugrá or Land O’Lakes for the filling, European-style butter for the crust. Freshly grated nutmeg makes all the difference—Penzeys sells pre-grated, but toasting whole nutmeg seeds first gives deeper flavor.

No evaporated milk? Heavy cream plus powdered milk works in a pinch, but the filling won’t be as rich. Substituting marshmallows? Toasted coconut flakes add texture but lack sweetness—stick with marshmallows for that classic gooey contrast. The pie crust can be store-bought (Pepperidge Farm works), but homemade is worth the effort. For the spices, McCormick’s ground cinnamon is reliable, but if you’ve got whole sticks, toast and grind them fresh. The crust butter should be cold and cubed—never softened, or you’ll end up with tough pastry.

Pie filling keeps 3 days in the fridge—bake it early and store it covered. The meringue topping? Best eaten the same day—it loses its crackly texture overnight. For make-ahead baking, assemble the pie (without meringue), refrigerate overnight, then bake the meringue fresh. Freeze the whole pie (unbaked) for 2 months—just add meringue and bake straight from frozen. Leftovers? Slice and reheat at 350°F for 10 minutes to revive the meringue’s crisp.

Step-by-step instructions for sweet potato pie with toasted meringue

Here's how to assemble this showstopper—creamy filling meets golden meringue magic.

Preheat your oven to 350°F. Peel the 2 lbs large russet potatoes and cut them into 1-inch chunks. Place them in a pot of cold water and bring to a boil. Reduce heat and simmer for 15-20 minutes until fork-tender. Drain well and return them to the pot.

Using a potato masher or ricer, mash the potatoes until completely smooth. Stir in the 1.5 cups granulated sugar, 0.5 cup light brown sugar, 1 cup evaporated milk, 0.5 cup melted unsalted butter, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 0.5 tsp ground ginger, 0.5 tsp salt, and 1 tbsp vanilla extract. Mix until the filling is completely homogeneous and silky smooth. This is your flavor base—take your time here for that perfect texture.

In a large bowl, combine the 2.5 cups all-purpose flour and 1 cup cold unsalted butter cut into small cubes. Use a pastry cutter or your fingers to work the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces. Gradually add the 0.5 cup ice water, 1 tablespoon at a time, mixing gently just until the dough comes together.

Turn the dough onto a lightly floured surface and knead it 4-5 times until smooth. Divide the dough into two equal parts, flatten each into a disk, wrap in plastic wrap, and refrigerate for at least 1 hour. Chilling prevents shrinking and makes rolling easier. Meanwhile, preheat your oven to 375°F for the next step.

Roll out one disk of dough on a floured surface into a 12-inch circle (about 1/8-inch thick). Transfer it to a 9-inch pie dish, gently pressing it into the bottom and sides. Trim any excess dough, leaving about 1/2-inch overhang. Roll out the second disk and cut into strips for the lattice crust.

Line the bottom crust with parchment paper, fill it with pie weights or dried beans, and bake for 15 minutes. Remove the weights and bake for another 5 minutes until the edges are just starting to golden. This blind-baking ensures a crisp crust that won't sog when filled. Let the crust cool slightly before filling.

Pour the sweet potato filling into the pre-baked crust, spreading it evenly. Arrange the 2 cups mini marshmallows on top in a single layer, pressing them lightly into the filling. This creates that signature marshmallow crown we all love. Bake for 45-50 minutes until the filling is set but still slightly jiggly in the center.

While the pie bakes, prepare the meringue. In a separate bowl, beat the 6 whole large eggs at room temperature until frothy. Gradually add the remaining 1.5 cups granulated sugar, beating on medium speed until the mixture is thick, glossy, and holds stiff peaks when the beaters are lifted. This should take about 5-7 minutes. Spread the meringue evenly over the hot pie, sealing it to the edges to prevent shrinking.

Immediately increase the oven temperature to 400°F and place the pie back in for 5-7 minutes until the meringue is deep golden brown and toasted. Watch closely—it can go from perfect to burnt in seconds. Let the pie cool completely on a wire rack before slicing. The contrast of the warm, spiced filling with the crisp, toasted meringue is what makes this pie extraordinary.

Serve slices warm or at room temperature. The marshmallows should be soft and gooey, the filling rich and velvety, and the meringue crown should crackle with every bite. Store leftovers in the refrigerator for up to 3 days, though I doubt any will last that long!

Serving suggestions for leftovers

Classic Presentation

Serve slices on white china plates with a dusting of powdered sugar for an elegant touch. I like to garnish each slice with a sprinkle of flaky sea salt and a drizzle of warm caramel sauce to enhance the marshmallow's gooey texture.

The contrast of colors—golden meringue, creamy filling, and white plate—makes every bite feel like a special occasion. 🍽️

Holiday Platter Styling

For Thanksgiving or Christmas, arrange pie slices on a wooden board surrounded by candied pecans and whipped cream dollops. Add a few cranberry sauce drizzles for a festive pop of color.

I always include a small bowl of vanilla ice cream on the side for scooping. The warm pie against cold ice cream creates the perfect temperature contrast. 🎄

Coffee Pairings

Serve warm slices with a strong cup of coffee—I recommend dark roast like Starbucks Sumatra or local craft roasts from your favorite shop. The bitterness of the coffee cuts through the sweetness beautifully. For a cozy night in, pair with chocolate-dipped shortbread cookies to balance the flavors. 💛

Make-Ahead Serving

Assemble the pie (without meringue) one day ahead and refrigerate. Bake fresh with meringue the next morning for restaurant-quality results. Store leftovers in an airtight container with parchment between slices to keep the meringue crisp. Reheat slices at 350°F for 10 minutes to revive the meringue’s texture before serving. ⏰

Dessert Board Idea

Create a dessert board with pie slices, mini pumpkin muffins, and spiced apple slices. Add candied ginger for a zesty contrast and gold leaf flakes for a luxurious finish.

This visually stunning display is perfect for dinner parties or family gatherings. The combination of textures and flavors makes every bite exciting. ✨

Kids' Fun Twist

Cut the pie into fun shapes using a pie cutter or cookie cutters for kids' parties. Serve with mini ice cream cones and sprinkles for a playful dessert table. The marshmallow topping makes it extra fun—let them dig in for the gooey surprises! 🧸
