How to Make Sweet Potato Pie with Marshmallow Topping

Step 1: Prepare Your Pie Crust

Start by making sure you have a chilled pie crust ready. The crust forms the sturdy yet flaky bottom and edges of your pie, so having it cold and rested before rolling out is essential to prevent shrinkage and maintain that beautiful texture.

Step 2: Cook the Sweet Potatoes

Place the sweet potatoes in a large saucepan, cover with water, and bring to a boil. Let them cook until they are very soft—this takes about 45 to 50 minutes. Boiling softens the potatoes to create that silky smooth filling everyone loves in a Sweet Potato Pie with Marshmallow Topping.

Step 3: Roll Out and Chill the Dough

On a floured surface, roll your pie dough to a 12-inch diameter circle. Carefully transfer it into a 9-inch pie dish, smoothing it out and forming a thick, pretty edge by folding any excess dough over and crimping or fluting. Brush the edges with egg wash and chill it for at least 15 minutes to keep it from shrinking when baked.

Step 4: Make the Filling

Peel the boiled sweet potatoes after cooling slightly—they should slip right off. Then, blend or beat the potatoes until completely smooth. Add in soft butter, brown sugar, cream, bourbon, eggs, flour, vanilla, and your fragrant spices. Whip everything on high until silky and well combined, then pour this luscious filling into your chilled pie crust.

Step 5: Bake the Pie

Bake the filled pie at 350°F (177°C) for 55 to 60 minutes, or until the center is just slightly jiggly when you gently shake the pan. Keep an eye on the crust edges; if they brown too fast, shield them with foil. Let the pie cool fully on a wire rack—it will set and the flavor will deepen as it rests.

Step 6: Prepare and Add the Marshmallow Topping

For the show-stopping marshmallow topping, whisk egg whites, sugar, and cream of tartar over simmering water until smooth and warm, then beat until stiff, glossy peaks form. Fold in vanilla and spread this billowy meringue over the cooled pie. If you want, use a kitchen torch or the oven to toast the topping lightly, adding a gorgeous golden finish that makes this Sweet Potato Pie with Marshmallow Topping truly irresistible.

How to Serve Sweet Potato Pie with Marshmallow Topping

Garnishes

Adding a sprinkle of crushed pecans or a light dusting of cinnamon on the marshmallow topping creates an inviting contrast in texture and taste. A small dollop of whipped cream is always welcome and pairs beautifully with the sweetness of the topping.

Side Dishes

This pie shines as part of a festive holiday spread alongside spiced cider or a robust cup of coffee. For a balanced dessert experience, serve it with fresh fruit or a scoop of vanilla bean ice cream to complement the warm spices and creamy filling.

Creative Ways to Present

Slice the pie into generous wedges and place each piece on rustic wooden boards for a charming autumn vibe. You can also serve mini versions in ramekins topped with individual marshmallow dollops. For extra flair, a quick drizzle of caramel sauce adds decadence and a rich counterpoint to the spiced filling.

Make Ahead and Storage

Storing Leftovers

Once cooled, Sweet Potato Pie with Marshmallow Topping can be stored uncovered at room temperature for up to 8 hours, which keeps the marshmallow topping light and fluffy. For longer freshness, cover and refrigerate the pie for up to 5 days—just be aware the topping may soften a bit.

Freezing

Freezing this pie is best done before adding the marshmallow topping. Wrap the baked pie tightly with plastic wrap and aluminum foil, then freeze for up to 2 months. When ready, thaw in the refrigerator overnight and add fresh marshmallow meringue before serving for the best texture and flavor.

Reheating

Warm slices gently in the oven at 325°F (160°C) for about 10-15 minutes to regain a freshly baked feel without compromising the marshmallow topping. Avoid microwaving as it can make the topping gummy.

FAQs

Can I use canned sweet potatoes for this pie?

While fresh sweet potatoes give the best flavor and texture, you can substitute canned sweet potatoes if needed. Just make sure to drain them well and mash thoroughly to avoid excess moisture in the filling.

Is bourbon necessary in the recipe?

The bourbon is optional but highly recommended. It adds a subtle warmth and depth that elevates the pie. However, you can omit it without sacrificing the essential flavor of the sweet potato filling.

How do I prevent the crust edges from burning?

If you notice the crust edges browning too quickly during baking, cover them with a pie crust shield or loosely wrap strips of aluminum foil around the edges about halfway through the bake time. This protects the crust while the filling finishes cooking.

Can I make the marshmallow topping ahead of time?

The marshmallow topping is best made right before serving to maintain its fluffy texture and glossy appearance. If needed, you can prepare it a few hours in advance and keep it covered at room temperature, but avoid refrigerating to prevent it from weeping.

How do I get that wiggly-but-set filling texture?

The slight jiggle in the center after baking means the custard is perfectly set but still moist and creamy. Overbaking will dry out the filling, so aim for about 55-60 minutes and test with a toothpick for mostly clean removal with a tiny touch of custard sticking.

Final Thoughts

Trust me when I say, the Sweet Potato Pie with Marshmallow Topping is a pie you will want to make again and again. Its combination of velvety sweet potato filling spiced just right, alongside that dreamy marshmallow cloud, creates a dessert that is both nostalgic and uniquely special. So gather your ingredients, invite your loved ones, and dive into this homemade slice of holiday happiness—you won’t regret it!
