Ingredients You’ll Need
This recipe keeps things simple with straightforward ingredients that contribute layers of flavor, color, and texture. Each item plays an essential role—from the rich sweetness of Stokes purple sweet potatoes to the silky, glossy Swiss meringue that crowns the pie perfectly.
- 1 perfect pie crust: A homemade flaky pie crust offers the perfect buttery and crisp base to hold that luscious filling.
- 1 pound Stokes purple sweet potatoes: These are the star of the show, giving the pie its signature beautiful purple hue and natural sweetness.
- 1 cup light brown sugar: Adds a warm, caramel-like sweetness that deepens the flavor.
- 2 large eggs (room temperature): Help bind the filling while adding richness and structure.
- 3/4 cup evaporated milk: Gives the filling a creamy, velvety texture without weighing it down.
- 1/4 cup unsalted butter (melted): Adds moisture and enhances the richness of the filling.
- 1 tablespoon vanilla extract: Infuses the filling with a comforting, aromatic depth.
- 2 teaspoons pumpkin pie spice: Introduces cozy autumnal spices that complement the sweet potato perfectly.
- 1/2 teaspoon kosher salt: Balances the sweetness and enhances all the flavors.
- 3 large egg whites (room temperature): The base for the Swiss meringue, creating that light, airy topping.
- 1/4 teaspoon cream of tartar: Stabilizes the egg whites for a glossy and firm meringue.
- 3/4 cup granulated sugar: Sweetens and helps create a smooth, glossy meringue finish.
How to Make Purple Sweet Potato Pie with Swiss Meringue Topping Recipe
Step 1: Prepare and Blind Bake Your Pie Crust
Start by preparing your homemade flaky pie crust. Roll out half of your dough on a lightly floured surface to about 1/4 inch thickness and a bit wider than your pie pan. Fit it carefully into the pan, trim excess dough, crimp the edges beautifully, and poke the bottom with a fork to prevent bubbling. Chill the crust in the freezer for at least 30 minutes to keep it from shrinking during baking. Then, preheat your oven to 425°F, line the crust with parchment paper or foil, fill with pie weights or dried beans, and blind bake it. After 15 minutes, remove the weights and bake for another 5 minutes until the bottom is just starting to brown. Let the crust cool while you work on the filling.
Step 2: Roast the Purple Sweet Potatoes
Prick the purple sweet potatoes with a fork and wrap them in foil. Place them on a baking sheet and roast in the oven at 400°F for about an hour, until they are fork-tender and soft. This slow roasting enhances their natural sweetness and makes them easy to mash into a smooth filling.
Step 3: Make the Sweet Potato Filling
Once roasted and cooled slightly, scoop the sweet potato flesh into a blender and puree until silky smooth—you should have about 2 cups. Transfer this to a large mixing bowl, then add your light brown sugar, eggs, evaporated milk, melted butter, vanilla extract, pumpkin pie spice, and kosher salt. Mix everything thoroughly until the filling is completely smooth and well combined. This filling promises that melt-in-your-mouth texture with deep, comforting flavors.
Step 4: Bake the Pie Filling
Pour your luscious sweet potato mixture evenly into the pre-baked pie crust. Place the pie back in the oven at 400°F for 15 minutes, then reduce the heat to 350°F and continue baking for another 25 to 35 minutes. You’ll know it’s ready when the edges are set but the center still jiggles slightly—it should be creamy and custardy once fully cooled. Let the pie cool to room temperature for about an hour, then refrigerate for at least two hours before adding the meringue. This chilling time allows the filling to set beautifully and makes topping easier.
Step 5: Prepare the Swiss Meringue Topping
Set up a double boiler with simmering water on your stove. In a heatproof bowl, whisk together the egg whites, cream of tartar, and granulated sugar. Place the bowl over the simmering water and whisk constantly until the sugar dissolves completely and the mixture is warm (about 160°F), approximately 3 to 4 minutes. Then transfer the bowl to a stand mixer fitted with a whisk attachment and beat on high until stiff, glossy peaks form and the mixture has cooled completely, about 10 to 15 minutes. If the meringue isn’t quite stiff, pop it in the fridge for 10 minutes and continue whipping. This silky Swiss meringue is what makes this pie truly special.
Step 6: Top and Finish Your Pie
Once the filling is chilled and set, spread the Swiss meringue evenly over the top of the pie. For that eye-catching golden finish, use a culinary torch to toast the meringue to a light brown shade. This caramelized exterior contrasts beautifully with the pillowy meringue beneath and adds a subtle smoky flavor that rounds out the sweetness. Your Purple Sweet Potato Pie with Swiss Meringue Topping Recipe is now ready to impress!
How to Serve Purple Sweet Potato Pie with Swiss Meringue Topping Recipe
Garnishes
Consider fresh whipped cream or a sprinkle of toasted pecans for added crunch and richness. A light dusting of ground cinnamon or nutmeg on the meringue can also add a lovely aromatic touch that complements the pie’s warm spices beautifully.
Side Dishes
Serve this pie alongside a cup of rich spiced chai tea or coffee to balance the sweetness. For a festive meal, pair it with roasted turkey or a simple green salad to create a wholesome autumn-inspired spread.
Creative Ways to Present
Try slicing this pie into individual mini servings using small tart pans for a charming dessert presentation. Alternatively, use a piping bag to swirl the Swiss meringue decoratively on top before torching—this makes for a stunning centerpiece at any gathering.
Make Ahead and Storage
Storing Leftovers
You can store leftover Purple Sweet Potato Pie with Swiss Meringue Topping Recipe in the refrigerator, covered loosely with plastic wrap or stored in an airtight container, for 3 to 4 days. This gives you plenty of time to enjoy every last bite without sacrificing freshness or texture.
Freezing
While the pie can be frozen, it’s best to freeze it before adding the meringue topping. Wrap the cooled baked pie tightly in plastic wrap and then aluminum foil. Freeze for up to 1 month. When ready to serve, thaw overnight in the refrigerator, then prepare the Swiss meringue topping fresh.
Reheating
The pie is best enjoyed chilled or at room temperature, so reheat gently if desired by letting it sit out for about 30 minutes. Avoid microwaving as it can melt the meringue and change the texture. If you must warm it, use a low oven for just a few minutes to take the chill off.
FAQs
Can I use regular sweet potatoes instead of purple sweet potatoes?
Absolutely! Regular sweet potatoes will work, though the vibrant purple color and subtle flavor unique to purple sweet potatoes will be missed. The taste will still be delicious though.
Why is Swiss meringue better for topping compared to other meringues?
Swiss meringue is gently heated and whipped until glossy and stable, resulting in a smooth, silky texture that holds up well on pies. It is less sweet than some meringues and has a beautiful sheen, making it perfect for this pie.
What do I do if my meringue isn’t stiff enough?
If your meringue isn’t stiff enough after beating, chill the bowl and whisk for 10 minutes, then continue whipping. Sometimes the bowl or ingredients being too warm can prevent stiff peaks from forming immediately.
Can I use a store-bought pie crust?
Yes, you can! A good quality store-bought crust works in a pinch but making your own flaky crust really elevates the texture and flavor of the finished pie.
How long does it take to prepare this pie from start to finish?
The entire process takes about 3 hours and 25 minutes, including baking, cooling, and chilling times to achieve the perfect texture for the filling and topping.

- 1 pound Stokes purple sweet potatoes
- 1 cup light brown sugar

- 1 tablespoon vanilla extract
- 2 teaspoons pumpkin pie spice
- 1/2 teaspoon kosher salt
Swiss Meringue Topping
- 3 large egg whites (room temperature)
- 1/4 teaspoon cream of tartar
- 3/4 cup granulated sugar
Instructions
- Prepare Pie Crust: Prepare one half of your homemade flaky pie crust recipe, shape it into a disk, and chill it in the fridge for at least 30 minutes to relax the dough.
- Roll and Fit Crust: On a lightly floured surface, roll out the chilled dough to about 1/4 inch thickness and 2 inches wider than your pie pan. Transfer it to the pan, trim the excess dough, and crimp or decorate the edges as desired. Poke the bottom with a fork to prevent air bubbles.
- Chill Crust: Place the pie crust in the freezer for at least 30 minutes to prevent shrinking during baking. Meanwhile, preheat the oven to 425°F (220°C).
- Blind Bake Crust: Line the crust with parchment paper or foil, fill it with pie weights or dry beans/rice, and bake at 425°F for 15 minutes. Remove the weights and bake an additional 5 minutes until the bottom starts to brown. Let it cool.
- Cook Sweet Potatoes: Preheat oven to 400°F (200°C). Prick the sweet potatoes with a fork and wrap them in foil. Bake on a sheet for about 1 hour until very soft.
- Make Sweet Potato Filling: Scoop the cooked sweet potato flesh into a blender and blend until smooth and creamy to make about 2 cups. In a large bowl, combine mashed sweet potato, brown sugar, eggs, evaporated milk, melted butter, vanilla extract, pumpkin pie spice, and kosher salt. Mix until smooth.
- Fill Pie Crust: Pour the sweet potato mixture into the par-baked pie crust and spread evenly.
- Bake Pie: Bake at 400°F for 15 minutes, then reduce heat to 350°F (175°C) and bake for an additional 25-35 minutes until the edges are set and the center jiggles slightly. Cool the pie to room temperature for about 1 hour, then chill it for at least 2 hours before topping.
- Prepare Swiss Meringue: Set up a double boiler with simmering water. In a heat-safe bowl, whisk together egg whites, cream of tartar, and granulated sugar. Place the bowl over the simmering water and whisk constantly until the sugar dissolves and the mixture reaches 160°F (71°C), approximately 3-4 minutes.
- Whip Meringue: Transfer the bowl to a stand mixer fitted with the whisk attachment. Beat on high speed until stiff peaks form and the meringue is no longer warm, about 10-15 minutes. If not stiff enough, chill the bowl for 10 minutes and continue beating.
- Finish Pie: Evenly spread the Swiss meringue over the chilled sweet potato pie. Use a culinary torch to toast the meringue to a golden brown, creating a beautiful finish.
Notes
- Ensure the eggs and egg whites are at room temperature for better volume and stability in the filling and meringue.
- Blind baking the crust prevents it from becoming soggy once filled.
- Use a digital thermometer to monitor the meringue temperature closely while whisking over the double boiler.
- Chilling the pie before adding the meringue topping helps maintain structure and prevents melting.
- If you don’t have a culinary torch, you can place the meringue-topped pie under the broiler for 1-2 minutes watching carefully to prevent burning.
- This pie can be stored covered in the refrigerator for up to 3 days.
