Ingredients You’ll Need
Don’t let the list intimidate you—each ingredient is straightforward but plays a vital role in perfecting this pie. From the naturally colorful purple sweet potatoes to the silky Swiss meringue, these ingredients combine to deliver a balanced, irresistible dessert.
- Pie crust: A flaky homemade crust creates the perfect buttery base that supports the filling beautifully.
- Purple sweet potatoes (1 pound): These provide vibrant color and a naturally sweet, creamy texture to the filling.
- Light brown sugar (1 cup): Adds sweetness with a touch of molasses depth that complements the sweet potatoes.
- Large eggs (2, room temperature): Key for binding the filling and providing a custardy richness.
- Evaporated milk (3/4 cup): This adds creaminess without excess water, ensuring a silky texture.
- Unsalted butter (1/4 cup, melted): Invites richness and helps mellow the spices.
- Vanilla extract (1 tablespoon): Enhances the natural sweetness and rounds out flavors.
- Pumpkin pie spice (2 teaspoons): Warms the pie with cozy notes of cinnamon, nutmeg, and cloves.
- Kosher salt (1/2 teaspoon): Balances sweetness and intensifies all the flavors.
- Egg whites (3 large, room temperature): Whipped for the Swiss meringue topping to add lightness and elegance.
- Cream of tartar (1/4 teaspoon): Stabilizes the meringue, helping it hold stiff peaks.
- Granulated sugar (3/4 cup): Sweetens and thickens the meringue for that glossy, toasted finish.
How to Make Purple Sweet Potato Pie with Swiss Meringue Topping Recipe
Step 1: Prepare and Chill the Pie Crust
Start with your flaky homemade pie crust, forming it into a disk and chilling it for at least 30 minutes. This relaxation time stops the dough from shrinking during baking and ensures a tender, buttery base that’s easy to roll out.
Step 2: Roll Out and Fit the Crust
On a lightly floured surface, gently roll the dough to about 1/4 inch thickness, making it a couple of inches wider than your pie pan. Transfer the dough carefully to the pan, trim any excess, and add a decorative edge or crimp for that classic look. Don’t forget to poke the bottom with a fork to avoid air bubbles from forming while baking.
Step 3: Chill and Blind Bake
Pop the crust in the freezer for at least 30 minutes to keep it from shrinking. Meanwhile, preheat your oven to 425°F. Line the crust with parchment or foil and fill it with pie weights, dried beans, or rice to protect the crust’s shape. Bake for 15 minutes, remove the weights, then bake 5 more minutes until the bottom starts to turn golden. Allow it to cool completely.
Step 4: Roast the Purple Sweet Potatoes
Preheat your oven to 400°F. Prick the sweet potatoes with a fork, wrap them individually in foil, and bake for about an hour until they are soft and tender all the way through. This step brings out their natural sweetness and smooth texture.
Step 5: Prepare the Sweet Potato Filling
Once the sweet potatoes are cool enough to handle, scoop out the flesh and blend it until perfectly smooth—about 2 cups. In a large mixing bowl, combine the mashed sweet potatoes with brown sugar, eggs, evaporated milk, melted butter, vanilla, pumpkin pie spice, and salt. Mix everything until silky and fully combined.
Step 6: Fill the Pie Crust and Bake
Pour your sweet potato filling into the prepared and cooled pie crust, smoothing the top. Bake at 400°F for 15 minutes, then reduce the oven temperature to 350°F and continue baking for another 25 to 35 minutes. You’ll know it’s ready when the edges are set and the center still jiggles gently. Let the pie cool to room temperature, then chill for at least two hours so it sets nicely before adding the topping.
Step 7: Make the Swiss Meringue
Set up a double boiler with gently simmering water. In a heat-safe bowl, whisk together the egg whites, cream of tartar, and granulated sugar. Place the bowl over the steaming water and whisk constantly until the sugar dissolves completely and the mixture reaches 160°F, which takes about 3 to 4 minutes.
Step 8: Whip and Top
Transfer the warm mixture to your stand mixer fitted with a whisk attachment. Beat on high speed until stiff, glossy peaks form and the mixture cools down—about 10 to 15 minutes. If it’s not quite stiff enough, chill the bowl for a few minutes and continue whipping. Spread the Swiss meringue evenly over the chilled sweet potato pie.
Step 9: Toast the Meringue
If you have a culinary torch, gently toast the meringue until it reaches a gorgeous golden brown. This adds a lovely texture contrast and a hint of caramelized flavor that elevates the entire dessert.
How to Serve Purple Sweet Potato Pie with Swiss Meringue Topping Recipe
Garnishes
Simple is best here. A sprinkle of toasted pecans or a few freshly grated nutmeg shavings adds a lovely nutty crunch and extra warmth. For a touch of elegance, add a few edible flowers or a dusting of cinnamon on the meringue’s peaks.
Side Dishes
This pie pairs wonderfully with a scoop of vanilla bean ice cream or a spoonful of lightly whipped cream. For a lighter option, fresh berries or a citrusy orange salad offer a bright contrast to the rich pie flavors.
Creative Ways to Present
Try serving individual mini pies or tartlets topped with piped Swiss meringue for an impressive presentation. Alternatively, plate slices with a drizzle of caramel sauce and a sprig of mint to truly impress your guests.
Make Ahead and Storage
Storing Leftovers
Wrap the leftover pie tightly with plastic wrap or place it in an airtight container. Store it in the refrigerator, where it will keep its freshness and creamy texture for up to 3 days.
Freezing
You can freeze the baked pie without the meringue topping wrapped well in plastic and foil for up to one month. When ready to enjoy, thaw it overnight in the fridge and prepare the Swiss meringue topping freshly before serving.
Reheating
Gently warm pie slices in a low oven (around 300°F) for 10 to 15 minutes to refresh the filling without melting the meringue. If you’ve already topped it, skip reheating to preserve the delicate meringue texture.
FAQs
Can I use regular orange sweet potatoes instead of purple ones?
Absolutely! Regular sweet potatoes work well, but you’ll lose the signature vibrant purple color that makes this pie so special. The flavor will still be delicious and comforting.
Why is it important to chill the pie crust before baking?
Chilling the crust helps relax the gluten, preventing shrinking and helps maintain a flaky, tender crust that bakes evenly without puffing up.
What’s the best way to make sure my Swiss meringue is stable?
Use room temperature egg whites and cream of tartar, and whisk over simmering water until the sugar fully dissolves. This process ensures the meringue is smooth and glossy, then whipping it well forms stiff, stable peaks.
Can I make the Swiss meringue topping ahead of time?
Swiss meringue is best made fresh and spread immediately on the chilled pie. If made in advance, it can lose its volume and texture.
How do I store the pie if I want to serve it the next day?
Cover the pie loosely with foil or a cake dome and refrigerate. Add the meringue topping just before serving to keep it light and fluffy.

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 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 to the pan, trim excess dough, and crimp or decorate 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. Preheat oven to 425°F while chilling.
- Blind Bake Crust: Line the crust with parchment paper or foil, fill with pie weights or dry beans/rice, and bake at 425°F for 15 minutes. Remove weights and bake an additional 5 minutes until the bottom begins to brown. Let cool.
- Cook Sweet Potatoes: Preheat oven to 400°F. Prick potatoes with a fork and wrap in foil. Bake on a sheet for about 1 hour until very soft.
- Make Sweet Potato Filling: Scoop cooked sweet potato flesh into a blender and blend until smooth and creamy, about 2 cups. In a large bowl, combine mashed sweet potato, brown sugar, eggs, evaporated milk, melted butter, vanilla, pumpkin pie spice, and salt. Mix until smooth.
- Fill Pie Crust: Pour the sweet potato mixture into the par-baked pie crust, spreading evenly.
- Bake Pie: Bake at 400°F for 15 minutes, then reduce heat to 350°F and bake for an additional 25-35 minutes until edges are set and the center jiggles slightly. Cool to room temperature for about 1 hour, then chill at least 2 hours before topping.
- Prepare Swiss Meringue: Set up a double boiler with simmering water. In a heat-safe bowl, whisk egg whites, cream of tartar, and sugar. Place the bowl over simmering water, whisking constantly until sugar dissolves and mixture reaches 160°F, about 3-4 minutes.
- Whip Meringue: Transfer bowl to a stand mixer fitted with whisk attachment. Beat on high until stiff peaks form and the meringue is no longer warm (about 10-15 minutes). If not stiff, chill bowl for 10 minutes and continue beating.
- Finish Pie: Spread the Swiss meringue over the chilled sweet potato pie evenly. Use a culinary torch to toast the meringue to a golden brown, creating a beautiful finish.
Notes
- Chilling the pie crust before baking helps prevent shrinking and ensures a flaky crust.
- Use room temperature eggs for better incorporation into the filling and meringue.
- Blind baking the crust prevents the bottom from becoming soggy when adding the filling.
- Allow the pie to chill completely before adding the meringue topping to ensure it holds shape.
- To toast the meringue without a torch, you can place the pie under a broiler for 1-2 minutes, watching carefully to avoid burning.
- Store leftover pie covered in the refrigerator and consume within 3 days for best freshness.
