Ingredients You’ll Need
This recipe calls for straightforward ingredients that come together beautifully, each playing its own role in texture, taste, and that gorgeous purple hue. You’ll find that simple pantry staples combined with the rich flavor of purple sweet potatoes make this pie truly special.
- Pie crust: Choose a perfectly flaky homemade pie crust to provide a buttery base that holds all the filling beautifully.
- Stokes purple sweet potatoes (1 pound): These give the pie its signature color and naturally sweet, creamy texture.
- Light brown sugar (1 cup): Offers depth with its molasses notes and helps balance the sweetness.
- Large eggs (2, room temperature): Help set the filling and add richness.
- Evaporated milk (3/4 cup): Adds creaminess and smooth texture to the filling.
- Unsalted butter (1/4 cup, melted): Brings richness and tenderizes the filling.
- Vanilla extract (1 tablespoon): Enhances all the flavors with warm, aromatic notes.
- Pumpkin pie spice (2 teaspoons): Adds cozy, spiced warmth that complements the sweet potato.
- Kosher salt (1/2 teaspoon): Balances and uplifts the sweetness.
- Egg whites (3 large, room temperature): The star ingredient for your Swiss meringue topping, creating that fluffy crown.
- Cream of tartar (1/4 teaspoon): Stabilizes the meringue so it whips perfectly.
- Granulated sugar (3/4 cup): Sweetens and stabilizes the Swiss meringue topping.
How to Make Purple Sweet Potato Pie with Swiss Meringue Topping Recipe
Step 1: Prepare Pie Crust
Start by preparing half of your flaky homemade pie crust dough, shaping it into a disk and chilling it for at least 30 minutes. This resting time helps the dough relax, making it easier to roll out and preventing shrinkage while baking—a crucial first step in achieving that perfect pie base.
Step 2: Roll and Fit Crust
On a lightly floured surface, roll the chilled dough to about 1/4 inch thick, ensuring it’s roughly 2 inches larger than your pie pan. Gently transfer it to the pan, trim any excess dough, then crimp or decorate the edges to your liking. Use a fork to poke small holes in the bottom, which stops air bubbles from forming and keeps your crust even.
Step 3: Chill and Blind Bake Crust
Pop the pie crust in the freezer for at least 30 minutes. Meanwhile, preheat your oven to 425°F. Once chilled, line the crust with parchment or foil and fill it with pie weights or dry beans. Bake for 15 minutes, then remove the weights and bake another 5 minutes until the bottom starts to turn golden. Let the crust cool completely—this step ensures a crispy crust that won’t get soggy once filled.
Step 4: Bake Purple Sweet Potatoes
Preheat your oven to 400°F, pierce the purple sweet potatoes with a fork, and wrap them in foil. Bake on a sheet pan for about an hour or until the potatoes are completely soft and tender inside. This slow roasting intensifies their sweet flavor and makes them easy to mash.
Step 5: Make Sweet Potato Filling
Once the potatoes are cool enough to handle, scoop out about 2 cups of flesh and puree it in a blender until creamy and smooth. In a large bowl, mix the sweet potato with brown sugar, eggs, evaporated milk, melted butter, vanilla, pumpkin pie spice, and salt until well combined. The result is a custardy filling bursting with sweet, spicy warmth.
Step 6: Fill and Bake Pie
Pour the luscious sweet potato filling into your pre-baked pie crust, smoothing it evenly. Bake at 400°F for 15 minutes, then reduce the temperature to 350°F and continue baking for 25 to 35 minutes. The edges should be set, and the center will jiggle slightly—perfection. Let the pie cool at room temperature for about an hour before chilling it in the refrigerator for at least two hours. This cooling time helps the filling settle, making slicing neater and flavors richer.
Step 7: 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. Keep whisking constantly as the mixture gently heats, dissolving the sugar and raising the temperature to 160°F. This step is key to creating that silky, safe-to-eat meringue base.
Step 8: Whip Swiss Meringue
Transfer the warm mixture to a stand mixer with a whisk attachment. Beat on high speed until stiff peaks form and the mixture is cool to the touch—this usually takes about 10 to 15 minutes. If it’s still a bit warm, chilling briefly helps to get that perfect lift and sheen.
Step 9: Finish the Pie with Meringue
Spread the gorgeous Swiss meringue generously over your chilled sweet potato pie. To add a stunning touch, use a culinary torch to gently toast the peaks to a golden brown. This step creates a beautiful contrast of colors and adds a slight caramelized flavor that elevates the entire pie experience.
How to Serve Purple Sweet Potato Pie with Swiss Meringue Topping Recipe
Garnishes
A simple dusting of cinnamon or a few toasted pecans sprinkled on top of the Swiss meringue adds a delightful texture and spice note, without overpowering the natural sweet flavor of the purple sweet potatoes. A few edible flowers can also complement the vibrant purple color beautifully.
Side Dishes
Pair this pie with a small scoop of vanilla bean ice cream or a dollop of freshly whipped cream to add cool creaminess against the warm spices. A cup of spiced chai tea or freshly brewed coffee makes this dessert even more comforting and satisfying.
Creative Ways to Present
For a fun twist, serve this pie in individual mini tart shells topped with tiny toasted meringue peaks. Another idea is to slice and layer with a drizzle of honey and crushed pistachios for a sophisticated look and texture contrast. The bold purple hue naturally makes the presentation stand out, so minimal decor lets the pie shine.
Make Ahead and Storage
Storing Leftovers
Keep any leftovers covered tightly in the refrigerator for up to 3 days. The Swiss meringue topping may soften over time but will still be delicious. Make sure to store the pie in a pie box or airtight container to protect it from absorbing other flavors.
Freezing
You can freeze the pie (without the meringue topping) wrapped tightly in plastic wrap and aluminum foil for up to 2 months. When ready to serve, thaw it in the refrigerator overnight and prepare a fresh Swiss meringue topping just before serving to retain that perfect fluffy texture.
Reheating
Reheat slices gently in a warm oven (about 300°F) for 10 to 15 minutes if you prefer it warm. Avoid using the microwave, as it can make the meringue rubbery and the crust soggy. If you froze the pie without meringue, be sure to add the topping fresh after warming.
FAQs
Can I use regular sweet potatoes instead of purple?
Absolutely! While purple sweet potatoes give the pie its signature vibrant color and unique flavor, regular sweet potatoes will also create a delicious pie with a more traditional orange hue. Just adjust the baking time slightly if needed.
What makes Swiss meringue different from other meringues?
Swiss meringue is made by gently heating the egg whites and sugar before whipping, which dissolves the sugar completely and results in a silky, glossy, and stable meringue. It’s less sweet and more stable than typical French meringue, perfect for spreading and torching.
Can I make the pie crust from store-bought dough?
Yes, you can use store-bought pie crust for convenience. Just choose a good-quality crust and follow the blind bake instructions carefully to avoid a soggy bottom crust that could detract from this otherwise perfect pie.
How long does it take to roast the purple sweet potatoes?
Roasting usually takes about 1 hour at 400°F to get them soft enough to mash smoothly. You can test by piercing with a fork; it should slide in easily with no resistance.
What can I use if I don’t have a culinary torch?
If you don’t have a torch, simply place the pie under the broiler on low, watching closely to toast the meringue evenly and prevent burning. This achieves a similar golden finish, though with less control.

Ingredients
Pie Crust
- 1 perfect pie crust (homemade flaky pie crust recommended)
Sweet Potato Filling
- 1 pound Stokes purple sweet potatoes
- 1 cup light brown sugar
- 2 large eggs (room temperature)
- 3/4 cup evaporated milk
- 1/4 cup unsalted butter (melted)
- 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, form it into a disk, and chill in the refrigerator 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 the dough to the pie pan, trim off the excess dough, and crimp or decorate the edges as desired. Poke the bottom of the crust with a fork to prevent air bubbles during baking.
- Chill Crust: Place the pie crust in the freezer for at least 30 minutes to prevent shrinking when baked. Meanwhile, preheat the oven to 425°F (220°C).
- Blind Bake Crust: Line the crust with parchment paper or aluminum foil, fill it with pie weights or dry beans/rice, and bake at 425°F for 15 minutes. Remove the weights and lining, then bake an additional 5 minutes until the bottom begins to brown. Allow the crust to cool.
- Cook Sweet Potatoes: Preheat the oven to 400°F (204°C). Prick the purple sweet potatoes several times with a fork and wrap them individually in foil. Place them on a baking sheet and bake for about 1 hour until very soft and easily pierced with a fork.
- Make Sweet Potato Filling: Once cooled, scoop the cooked sweet potato flesh into a blender and blend until smooth and creamy, yielding about 2 cups. In a large bowl, combine the mashed sweet potato, light brown sugar, eggs, evaporated milk, melted butter, vanilla extract, pumpkin pie spice, and kosher salt. Mix all the ingredients until smooth and well incorporated.
- Fill Pie Crust: Pour the sweet potato filling into the par-baked pie crust, spreading it evenly with a spatula.
- Bake Pie: Bake the pie in the oven at 400°F for 15 minutes. Then reduce the oven temperature to 350°F (175°C) and bake for an additional 25 to 35 minutes, or until the edges are set and the center still slightly jiggles. Remove from oven and allow to cool to room temperature for about 1 hour, then chill in the refrigerator for at least 2 hours before adding the topping.
- Prepare Swiss Meringue: Set up a double boiler with simmering water. In a heat-safe bowl, combine the egg whites, cream of tartar, and granulated sugar. Place the bowl over the simmering water and whisk constantly until the sugar is fully dissolved and the mixture reaches 160°F (71°C), about 3 to 4 minutes.
- Whip Meringue: Transfer the bowl to a stand mixer fitted with the whisk attachment. Beat the mixture on high speed until stiff peaks form and the meringue cools down to room temperature, about 10 to 15 minutes. If the meringue is not stiff enough, chill the bowl for 10 minutes and continue whipping.
- Finish Pie: Spread the Swiss meringue evenly over the chilled sweet potato pie. Using a culinary torch, carefully toast the meringue topping to a golden brown, creating a beautiful toasted finish. Serve immediately or keep chilled until serving.
Notes
- For best results, use room temperature eggs for both filling and meringue to achieve smooth consistency and volume.
- Blind baking the crust ensures a crisp bottom and prevents sogginess from the moist filling.
- Toasting the meringue with a culinary torch adds both flavor and visual appeal; alternatively, you can briefly broil the meringue if you don’t have a torch.
- Store leftover pie covered in the refrigerator for up to 3 days.
- Use a blender or food processor to puree the cooked sweet potatoes for the smoothest texture.
- Make sure the sweet potatoes are thoroughly cooked and soft to achieve the creamy filling.
