This Purple Sweet Potato Pie with Swiss Meringue Topping Recipe uses simple, wholesome ingredients that each play a crucial role in building flavor, texture, and that signature eye-catching color. From the earthy sweetness of purple sweet potatoes to the silky richness of evaporated milk and the delicate lightness of Swiss meringue, every component works in perfect harmony.
- Pie crust: A flaky, homemade pie crust provides the perfect buttery and sturdy base for this pie.
- Purple sweet potatoes (1 pound): Their vibrant color and natural sweetness form the heart of this dessert.
- Light brown sugar (1 cup): Adds a deep caramel flavor that complements the sweet potatoes beautifully.
- Large eggs (2): Bind the filling together for a smooth custard texture.
- Evaporated milk (3/4 cup): Gives creaminess without overpowering the filling.
- Unsalted butter (1/4 cup, melted): Adds richness and enhances the texture.
- Vanilla extract (1 tablespoon): Brightens flavors and adds warmth.
- Pumpkin pie spice (2 teaspoons): A cozy blend of cinnamon, nutmeg, and clove that brings aromatic depth.
- Kosher salt (1/2 teaspoon): Balances sweetness and intensifies flavors.
- Large egg whites (3): The base for the Swiss meringue topping, whipped to glossy perfection.
- Cream of tartar (1/4 teaspoon): Stabilizes the meringue for a smooth, fluffy texture.
- Granulated sugar (3/4 cup): Sweetens and helps create glossy stiff peaks in the meringue.
How to Make Purple Sweet Potato Pie with Swiss Meringue Topping Recipe
Step 1: Prepare and Chill the Pie Crust
Begin by preparing your homemade flaky pie crust. Shape half of your dough into a disk and let it chill in the fridge for at least 30 minutes. This resting period relaxes the gluten, making the dough easier to roll out and preventing shrinkage during baking. Trust me, this step is the foundation for a perfectly tender yet sturdy crust that can hold all that creamy filling brilliantly.
Step 2: Roll and Fit the Crust into the Pie Pan
On a lightly floured surface, roll out your chilled dough to about 1/4 inch thickness, leaving enough extra to hang over the edges by about 2 inches. Carefully transfer it into your pie pan, trim any excess dough, and crimp or decorate the edges as you like. To avoid air bubbles that can ruin your crust’s texture, gently prick the bottom with a fork. This thoughtful preparation will give you that beautiful homemade look and texture.
Step 3: Chill and Blind Bake the Crust
Pop the prepared crust into the freezer for at least 30 minutes to solidify the fat and prevent shrinking while baking. Preheat your oven to 425°F while the crust chills. Then line the crust with parchment paper or foil and fill it with pie weights or dried beans to keep it flat. Bake for 15 minutes, remove the weights, and bake for an additional 5 minutes until the bottom is lightly browned. Let it cool; this step ensures a crisp crust that won’t get soggy under the luscious filling.
Step 4: Roast the Purple Sweet Potatoes
While the crust bakes, preheat your oven to 400°F. Pierce the sweet potatoes with a fork, wrap each in foil, and roast them on a baking sheet for about an hour until they become very soft and tender. Roasting enhances their natural sweetness and gives you that intense purple color that makes this pie so unique and beautiful.
Step 5: Make the Sweet Potato Filling
Once roasted and cooled slightly, scoop out about 2 cups of sweet potato flesh and blend it until smooth and creamy. Transfer this to a large bowl and mix in light brown sugar, eggs, evaporated milk, melted butter, vanilla extract, pumpkin pie spice, and kosher salt until everything is silky and well combined. This mixture promises a filling that is rich, flavorful, and perfectly spiced.
Step 6: Fill and Bake the Pie
Pour the sweet potato filling evenly into your cooled pie crust. Bake it at 400°F for 15 minutes, then lower the heat to 350°F and bake for another 25-35 minutes. The edges should be set while the center retains a slight jiggle. Let the pie cool to room temperature for about an hour, then chill it in the fridge for at least 2 hours before adding your meringue topping. This chilling step helps the filling set beautifully.
Step 7: Prepare the Swiss Meringue
For the show-stopping Swiss meringue topping, set up a double boiler with simmering water. In a heatproof bowl, whisk together egg whites, cream of tartar, and granulated sugar. Place the bowl over the simmering water and whisk constantly until the sugar fully dissolves and the mixture reaches 160°F, which usually takes about 3 to 4 minutes. This heating process cooks the egg whites gently, ensuring a safe and glossy meringue.
Step 8: Whip the Meringue to Stiff Peaks
Transfer the warm mixture to your stand mixer fitted with a whisk attachment and beat on high speed. Continue whipping until the meringue cools and forms stiff, glossy peaks—this can take 10 to 15 minutes. If the meringue isn’t stiff yet, chill the bowl in the fridge for 10 minutes and continue whipping. The result should be a fluffy, stable topping that holds its shape beautifully.
Step 9: Top and Toast the Pie
Spread the Swiss meringue evenly over your chilled purple sweet potato pie. For that stunning golden finish, use a culinary torch to toast the peaks gently until they reach a lovely caramelized brown. This final step not only adds a brilliant look but also introduces a lightly smoky sweetness that contrasts perfectly with the creamy pie.
How to Serve Purple Sweet Potato Pie with Swiss Meringue Topping Recipe
Garnishes
A simple dusting of ground cinnamon or a few edible flowers can add a stunning finishing touch to this pie. For extra flair, sprinkle chopped toasted pecans or a drizzle of maple syrup over the meringue just before serving. These little touches play beautifully with the warm spices and seasonal sweetness of the pie.
Side Dishes
This pie pairs wonderfully with a dollop of freshly whipped cream or a scoop of vanilla bean ice cream, balancing the dense sweetness with creamy coolness. For a cozy fall meal, serve alongside hot spiced cider or lightly brewed chai tea to complement the pumpkin pie spice notes.
Creative Ways to Present
Try serving the pie in individual mini tart shells for an elegant party treat or layer slices between plates of fresh fruits like pomegranate seeds and sliced pears for a colorful presentation. You can also create a pie bar with assorted toppings like nuts, berries, and chocolate shavings to let guests customize their slices.
Make Ahead and Storage
Storing Leftovers
Store any leftover pie covered tightly with plastic wrap or foil in the refrigerator. It will stay fresh for up to 3 days, with the meringue retaining its beautiful texture if kept chilled. This makes it a great dessert to prepare in advance for holiday gatherings.
Freezing
While the pie can be frozen, the Swiss meringue topping does not freeze well and can become watery upon thawing. For best results, freeze the pie after baking and cooling the filling but before adding the meringue. Wrap tightly in plastic and foil, then thaw in the fridge overnight before topping and serving.
Reheating
If you want a warm slice, gently reheat the pie slice in a low oven at 300°F for about 10 minutes. Avoid microwaving as it can change the texture of the filling and meringue. Enjoy warm or chilled depending on your preference!
FAQs
Can I use regular sweet potatoes instead of purple ones?
Absolutely! Regular orange sweet potatoes work well too. The flavor remains deliciously sweet and creamy, though you’ll lose the signature purple color that gives this recipe its unique visual appeal.
Is Swiss meringue difficult to make?
Not at all! While it might sound fancy, Swiss meringue just requires gentle heating then whipping the egg whites and sugar until glossy and fluffy. Once you get the hang of it, it’s a wonderfully reliable way to create a smooth and stable topping.
Can I make the pie crust ahead of time?
Yes! You can prepare the pie crust dough a day ahead and keep it wrapped tightly in the refrigerator. This actually helps relax the dough, making it easier to roll and less likely to shrink during baking.
How long does it take to roast the purple sweet potatoes?
Roasting typically takes about 1 hour at 400°F until the potatoes are very soft and tender. This slow cooking develops their natural sweetness and vibrant purple color, essential for the best flavor and texture.
What if I don’t have a culinary torch to toast the meringue?
No worries! You can place the pie under a preheated broiler for just 1 to 2 minutes. Watch closely to prevent burning, and remove as soon as the meringue peaks turn golden brown for a similar effect.

- Chilling the pie after baking and before adding meringue ensures a stable topping.
- A culinary torch ensures an even, golden-brown finish, but the meringue topping can also be briefly broiled in the oven watching carefully to avoid burning.
- Homemade pie crust enhances texture and flavor, but store-bought crusts can be used as a shortcut.
