Ingredients You’ll Need
Gathering your ingredients for this pie is surprisingly straightforward, but each component plays a vital role in texture, flavor, and visual appeal. From the creamy purple sweet potatoes to the airy Swiss meringue topping, these essentials come together to make a dessert that’s memorable and delightful.
- Pie crust: A perfect flaky crust forms the buttery base to cradle our luscious sweet potato filling.
- Purple sweet potatoes (1 pound): Their vibrant hue and naturally sweet taste give this pie its signature color and flavor.
- Light brown sugar (1 cup): Adds richness and a hint of molasses, balancing the earthiness of the sweet potatoes.
- Large eggs (2, room temperature): Essential for binding the filling and creating a smooth texture.
- Evaporated milk (3/4 cup): Brings creaminess and a slight caramel undertone.
- Unsalted butter (1/4 cup, melted): Adds depth and silkiness to the filling.
- Vanilla extract (1 tablespoon): Enhances the natural sweetness with warm floral notes.
- Pumpkin pie spice (2 teaspoons): Imparts cozy spices like cinnamon and nutmeg, elevating the flavor profile.
- Kosher salt (1/2 teaspoon): Balances sweetness and brightens all the flavors.
- Large egg whites (3, room temperature): The foundation for your Swiss meringue topping, providing volume and structure.
- Cream of tartar (1/4 teaspoon): Stabilizes the meringue to keep it silky and glossy.
- Granulated sugar (3/4 cup): Sweetens and helps to whip the meringue to stiff, billowy peaks.
How to Make Purple Sweet Potato Pie with Swiss Meringue Topping Recipe
Step 1: Prepare and Chill the Pie Crust
Start by preparing your homemade flaky pie crust, 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 without shrinking during baking.
Step 2: Roll and Fit the Crust
On a lightly floured surface, roll the dough to about 1/4 inch thickness and ensure it’s 2 inches wider than your pie pan. Carefully transfer it into the pan, trim the edges, and decorate or crimp as you like. Don’t forget to poke the bottom with a fork to prevent pesky air bubbles!
Step 3: Chill and Blind Bake the Crust
Pop the crust into the freezer for 30 minutes to avoid shrinkage, then preheat your oven to 425°F. Line the crust with foil or parchment and fill with pie weights (or dried beans/rice). Blind bake for 15 minutes, remove weights, and bake another 5 minutes until the crust edges begin to brown. Let it cool while you prepare the filling.
Step 4: Cook the Purple Sweet Potatoes
Preheat your oven to 400°F, prick the sweet potatoes all over with a fork, and wrap them tightly in foil. Roast for about an hour until they’re incredibly soft—this brings out their natural sweetness and creamy texture perfect for the pie filling.
Step 5: Blend the Filling
Scoop out roughly 2 cups of soft sweet potato flesh and blend until silky smooth. In a large mixing bowl, combine the mashed potatoes with light brown sugar, eggs, evaporated milk, melted butter, vanilla, pumpkin pie spice, and kosher salt. Mix thoroughly until the filling is uniform and creamy.
Step 6: Fill and Bake the Pie
Pour the luscious purple sweet potato mixture into your par-baked crust, smoothing the surface. Bake at 400°F for 15 minutes, then lower the heat to 350°F and bake for another 25-35 minutes. You’re aiming for set edges and a slightly jiggly center. Allow the pie to cool at room temperature for an hour, then chill it in the fridge for at least two hours to set completely before topping.
Step 7: Make the Swiss Meringue Topping
Set up a double boiler with simmering water. In a heat-proof bowl, whisk the egg whites, cream of tartar, and granulated sugar continuously over the simmering water until the sugar dissolves and the mixture reaches 160°F. This step is key for food safety and ensuring a smooth meringue.
Step 8: Whisk to Stiff Peaks
Transfer the warm meringue to a stand mixer fitted with a whisk attachment. Beat on high speed until glossy stiff peaks form and the bowl is no longer warm—about 10-15 minutes. If it’s not quite there, chill briefly and continue whipping.
Step 9: Top and Torch the Pie
Spread the Swiss meringue evenly over the chilled purple sweet potato pie. Use a culinary torch to toast the meringue gently until it develops a beautiful golden-brown crust that adds a smoky-sweet complexity and irresistible texture.
How to Serve Purple Sweet Potato Pie with Swiss Meringue Topping Recipe
Garnishes
A simple dusting of cinnamon or a sprinkle of chopped toasted pecans on the meringue adds a lovely crunch and complementary spice. For a festive touch, scatter edible flowers or drizzle a little maple syrup on the side to heighten the pie’s natural sweetness.
Side Dishes
This pie pairs wonderfully with a scoop of vanilla bean ice cream or a dollop of freshly whipped cream. For a more decadent experience, serve alongside a hot cup of spiced chai latte or rich coffee to balance the creamy, dense texture of the pie.
Creative Ways to Present
For a show-stopping look, slice the pie into generous wedges and serve on colorful plates that contrast its deep violet filling. You can pipe the Swiss meringue artistically or even add little toasted meringue peaks for extra height and drama. Inviting your guests to torch their own slice can add a fun, interactive twist!
Make Ahead and Storage
Storing Leftovers
Leftover Purple Sweet Potato Pie with Swiss Meringue Topping Recipe keeps best when covered loosely with plastic wrap or stored in an airtight container in the refrigerator. It will remain delicious for up to 3 days, allowing the flavors to meld beautifully without the meringue losing its delightful texture.
Freezing
While the filling and crust freeze well, the Swiss meringue topping does not hold up to freezing. For best results, freeze the pie without the meringue in a sturdy container. When ready to enjoy, thaw overnight in the refrigerator and prepare a fresh Swiss meringue topping just before serving.
Reheating
Reheat slices gently in a low oven (around 275°F) for 10–15 minutes to warm the filling slightly without melting the meringue. Avoid microwaving to maintain the pie’s texture and to keep the meringue light and airy.
FAQs
Can I use regular sweet potatoes instead of purple ones?
You absolutely can! Regular sweet potatoes will produce a delicious pie but with a more traditional orange hue. The purple variety not only adds unique color but also a subtly different flavor that’s earthier and slightly nuttier.
Is Swiss meringue safe to eat since it uses raw egg whites?
Yes! The Swiss meringue topping is gently cooked over simmering water until it reaches 160°F, effectively pasteurizing the egg whites. This method ensures it’s safe while achieving that glossy, stable finish.
Can I make this pie vegan?
This Purple Sweet Potato Pie with Swiss Meringue Topping Recipe relies on eggs and dairy, but you can experiment with vegan substitutes like aquafaba for meringue and plant-based milks and butter alternatives in the filling, though textures and flavors may shift.
What if I don’t have a culinary torch?
No worries! You can place the meringue-topped pie under a hot broiler for 1-2 minutes, watching very carefully to achieve a golden brown without burning. Keep the oven door slightly ajar and stay close to avoid over-browning.
How can I adjust the sweetness of this pie?
You can reduce or increase the brown sugar and granulated sugar in the recipe to suit your taste. Remember that the natural sweetness of purple sweet potatoes helps keep the pie balanced, so start by adjusting small amounts before baking.
Final Thoughts
I promise once you try this Purple Sweet Potato Pie with Swiss Meringue Topping Recipe, it will become a beloved staple for your gatherings and cozy nights alike. Its vibrant color, the irresistible creamy texture, and the feather-light meringue topping make it truly special. Don’t hesitate to dive in and share this joyful dessert with friends and family—you’re in for a delicious treat that’s as fun to make as it is to eat!

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 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 the dough to the pan, trim 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. Preheat the oven to 425°F while chilling.
- Blind Bake Crust: Line the crust with parchment paper or foil and fill with pie weights or dry beans/rice. Bake at 425°F for 15 minutes. Remove the weights and bake an additional 5 minutes until the bottom begins to brown. Let cool.
- Cook Sweet Potatoes: Preheat the oven to 400°F. Prick the sweet potatoes with a fork and wrap each in foil. Place them on a baking sheet and bake 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, about 2 cups. In a large bowl, combine the mashed sweet potato, brown sugar, eggs, evaporated milk, melted butter, vanilla extract, pumpkin pie spice, and kosher salt. Mix until smooth and well combined.
- 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 the heat to 350°F and bake for an additional 25-35 minutes until the edges are set and the center jiggles slightly. Cool to room temperature for about 1 hour, then chill 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 the 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, about 3-4 minutes.
- Whip Meringue: Transfer the bowl to a stand mixer fitted with a whisk attachment. Beat on high speed until stiff peaks form and the meringue is no longer warm, about 10-15 minutes. If the meringue isn’t stiff enough, chill the bowl for 10 minutes and continue beating.
- Finish Pie: Spread the Swiss meringue evenly over the chilled sweet potato pie. Use a culinary torch to toast the meringue to a golden brown, creating a beautiful finish. Serve chilled or at room temperature.
Notes
- Ensure the sweet potatoes are very soft for a smooth filling.
- Room temperature eggs help the filling blend evenly.
- Chilling the pie before adding the meringue helps the topping set properly.
- A culinary torch is ideal for toasting meringue evenly without baking the pie further.
- Pie crust can be store-bought if short on time, but homemade flaky crust offers the best texture and flavor.
