This Southern Sweet Potato Pie is rich, smooth, perfectly spiced, and made with roasted sweet potatoes for incredible homemade flavor. Roasting the sweet potatoes concentrates their natural sweetness and creates a velvety filling that’s every bit as comforting as the pies served at holiday tables throughout the South.

Sweet potato pie has long been a cherished Southern dessert, especially during Thanksgiving and Christmas. While many recipes boil the sweet potatoes, I prefer roasting them first. It takes a little extra time, but the deeper flavor and creamy texture are absolutely worth it.

If you’re planning your holiday dessert table, be sure to try my Sweet Potato Pie with Condensed Milk, Classic Pumpkin Pie, Buttermilk Pie, and Possum Pie, too. They’re all reader favorites and perfect for special occasions.

✨ Before You Begin

✨ Roast, Don’t Boil: Roasting the sweet potatoes concentrates their natural sugars and creates a richer, sweeter filling than boiling. It’s a simple step that makes a big difference in flavor.

✨ Measure the Mashed Potatoes: After roasting and mashing, measure out exactly 2¾ cups. Too much sweet potato can make the filling dense and affect the texture.

✨ Start with Room-Temperature Ingredients: Let the butter, egg, and heavy cream come to room temperature before mixing. This helps create a smoother filling with fewer lumps.

✨ Don’t Skip Cooling Time: The pie will continue to set as it cools. Allow it to cool completely before slicing for the cleanest slices and best texture.

✨ Watch the Center: The pie is done when the center is just set and no longer looks wet. A slight jiggle is fine—it will firm up as it cools.

✨ Food Safety Tip: Because this pie contains eggs and dairy, refrigerate leftovers within 2 hours of serving.

Ingredients + Key Notes

Sweet Potatoes: You’ll need about 1¾ pounds of sweet potatoes. Roasting them before mashing brings out their natural sweetness and gives the pie a deeper, richer flavor than boiling.

Vegetable Oil: A small amount of oil helps the sweet potatoes roast evenly and caramelize slightly around the edges.

Butter: Adds richness and helps create a smooth, velvety filling. Mix it into the warm sweet potatoes so it melts completely.

Sugar: Sweetens the filling without overpowering the natural flavor of the sweet potatoes.

Ground Cinnamon + Nutmeg: These classic warm spices give the pie its signature Southern flavor. Feel free to add a pinch of cloves or allspice if you enjoy a more heavily spiced pie.

Egg: Helps bind the filling and gives it structure as it bakes.

Vanilla Extract: Enhances the sweetness and rounds out the flavor of the filling.

Baking Powder: An unusual but effective ingredient that helps create a lighter, smoother texture.

Heavy Cream: Adds richness and creates a silky filling without making the pie overly heavy.

Unbaked Pie Shell: Use your favorite homemade pie crust or a store-bought crust for convenience.

🥣 How To Make Southern Sweet Potato Pie

Roast the Sweet Potatoes: Toss the cubed sweet potatoes with vegetable oil and spread them on a baking sheet. Roast until fork-tender and lightly caramelized around the edges. Roasting intensifies their natural sweetness and creates a richer pie filling.

Mash Until Smooth: Transfer the roasted sweet potatoes to a large bowl and mash until smooth. Measure out 2¾ cups, then add the butter while the potatoes are still warm so it melts easily into the mixture.

Mix the Filling: Beat the sweet potatoes and butter together until creamy. Add the sugar, cinnamon, nutmeg, egg, and vanilla, mixing until everything is fully combined and smooth.

Add the Cream Mixture: Whisk the baking powder into the heavy cream, then stir it into the sweet potato mixture. This helps create a silky, velvety filling with a light texture.

Fill the Pie Shell: Pour the filling into the unbaked pie crust, smoothing the top and gently mounding it slightly in the center.

Bake Until Set: Bake until the center is set and the top is lightly browned. The pie may still have a slight jiggle in the very center, but it will continue to firm up as it cools.

Cool Completely: Allow the pie to cool to room temperature before slicing. This gives the filling time to fully set and makes serving much easier.

⭐ Pro Tips

✨ Roast for Maximum Flavor: Roast the sweet potatoes until they’re fork-tender and beginning to caramelize around the edges. Those browned bits add incredible depth of flavor to the filling.

✨ Mash Thoroughly: For the smoothest pie, mash the sweet potatoes very well before adding the remaining ingredients. A handheld mixer works beautifully for creating a silky filling.

✨ Don’t Overmix the Egg: Once the egg is added, mix just until combined. Overmixing can incorporate excess air and cause the filling to puff up and crack as it cools.

✨ Use a Pie Shield if Needed: If the crust begins browning too quickly, loosely cover the edges with foil or a pie shield during the last part of baking.

✨ Let It Cool Completely: Sweet potato pie slices much more cleanly after it has fully cooled and set. If time allows, chill it for a few hours before serving.

✨ Serve with Whipped Cream: A dollop of lightly sweetened whipped cream complements the warm spices and rich filling perfectly.

Storing + Freezing + Make-Ahead Instructions

Storing: Cover the cooled pie and store it in the refrigerator for up to 4 days. Because the filling contains eggs and dairy, it should not be left at room temperature for extended periods.

Freezing: Sweet potato pie freezes beautifully. Allow the pie to cool completely, then wrap it tightly in plastic wrap followed by a layer of aluminum foil. Freeze for up to 3 months.

To serve, thaw overnight in the refrigerator and bring to room temperature for about 30 minutes before slicing.

Make-Ahead: This Southern Sweet Potato Pie is an excellent make-ahead dessert for Thanksgiving, Christmas, and holiday gatherings. You can bake it 1-2 days in advance and store it covered in the refrigerator until ready to serve.

For maximum freshness, I like to use a technique called Hotel Wrapping. Wrap the completely cooled pie tightly in overlapping layers of plastic wrap so the wrap seals against itself. This helps keep air away from the pie and preserves its flavor and texture.

Frequently Asked Questions

◆ What makes a sweet potato pie Southern?

Southern sweet potato pie is made with mashed sweet potatoes, warm spices, butter, eggs, and a flaky pie crust. It’s a beloved holiday dessert throughout the South and is often served at Thanksgiving and Christmas gatherings.
