Sweet Potato Pie with Espresso-Chocolate Crust

Recipe by Ailene

This pie takes a Southern classic and wraps it in a bakery-style upgrade: a dark, flaky chocolate crust spiked with a hint of espresso. Roasting the sweet potatoes face-down concentrates their natural sugars, creating a silky, richly spiced filling that pairs perfectly with the bitter-cocoa notes of the crust. It’s all crowned with a toasted marshmallow-like Swiss meringue and a final hit of flaky sea salt for a dessert that demands a second slice.

  • Total TimeAbout 7 hours 30 minutes
  • Yield1 pie (serves 8) 1x

Ingredients

Scale

Espresso-Chocolate Crust

  • 1 1/4 cups all-purpose flour (150g), plus more for dusting
  • 1/2 cup cold unsalted butter (1 stick/113g), cubed
  • 1/4 cup Dutch-process cocoa powder (25g)
  • 1 tablespoon granulated sugar
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon instant espresso powder
  • 3 to 5 tablespoons ice water

Sweet Potato Filling

  • 2 pounds sweet potatoes (about 2 large or 3 medium)
  • 3/4 cup packed dark brown sugar (150g)
  • 1/2 cup heavy cream
  • 1/4 cup unsalted butter (56g), melted and slightly cooled
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground ginger
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon freshly grated nutmeg

Toasted Swiss Meringue

  • 3 large egg whites, room temperature
  • 3/4 cup granulated sugar (150g)
  • 1/2 teaspoon vanilla extract
  • 1/4 teaspoon cream of tartar
  • Flaky sea salt, for garnish

Instructions

  1. Mix the crust: In a food processor, pulse the flour, cocoa powder, 1 tablespoon granulated sugar, 1/2 teaspoon kosher salt, and espresso powder until combined. Scatter the cold butter cubes over the dry ingredients and pulse 6 to 8 times until the mixture resembles coarse meal with pea-sized butter clumps remaining.
  2. Hydrate and chill: Transfer the mixture to a bowl. Drizzle 3 tablespoons of ice water over the top and toss gently with a fork. Add more water, 1 tablespoon at a time, just until the dough holds together when squeezed. Form into a flat disk, wrap tightly in plastic wrap, and refrigerate for at least 2 hours.
  3. Roast the sweet potatoes: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper. Halve the sweet potatoes lengthwise and place them cut-side down on the parchment. Roast for 40 to 50 minutes, or until completely tender and oozing sticky juices. Let cool, then scoop the flesh from the skins. Measure out exactly 2 cups (about 450g) of sweet potato flesh and set aside.
  4. Roll and crimp: On a lightly floured surface, roll the chilled dough into a 12-inch circle about 1/8-inch thick. Gently transfer it to a 9-inch metal pie dish. Fold the overhang under itself and crimp the edges. Prick the bottom lightly with a fork, then freeze for 20 minutes to set the crimp.
  5. Blind bake the crust: Lower the oven temperature to 350°F (175°C). Line the chilled crust with parchment paper or heavy-duty foil, leaving plenty of overhang, and fill to the brim with pie weights or dried beans. Bake for 25 to 30 minutes until the edges look dry. Carefully remove the weights and parchment, and bake for another 5 to 10 minutes until the bottom is set and matte. Let cool slightly on a wire rack.
  6. Blend the filling: In a food processor (wiped clean from the dough), combine the 2 cups of sweet potato flesh, dark brown sugar, heavy cream, melted butter, eggs, 1 teaspoon vanilla extract, cinnamon, ginger, 1/2 teaspoon kosher salt, and nutmeg. Blend for 1 to 2 minutes, scraping down the sides as needed, until completely smooth and velvety.
  7. Bake the pie: Pour the filling into the warm, blind-baked crust, smoothing the top. Bake at 350°F (175°C) for 45 to 55 minutes. The pie is done when the edges are slightly puffed and the center jiggles gently like gelatin when nudged. Transfer to a wire rack and let cool for 1 hour, then refrigerate until completely chilled, at least 2 hours.
  8. Make the Swiss meringue: Set a medium heatproof bowl over a saucepan with 1 inch of simmering water (ensure the water doesn’t touch the bowl). Add the egg whites, 3/4 cup granulated sugar, and cream of tartar to the bowl. Whisk constantly until the sugar is completely dissolved and the mixture reaches 160°F (71°C) on an instant-read thermometer, about 4 to 6 minutes.
  9. Whip and toast: Carefully remove the bowl from the heat. Using an electric hand mixer or a stand mixer fitted with the whisk attachment, beat the egg white mixture on medium-high speed until glossy, stiff peaks form, about 5 to 7 minutes. Beat in the 1/2 teaspoon vanilla extract during the last minute.
  10. Garnish and serve: Pile the meringue onto the chilled pie, swirling it into dramatic peaks with the back of a spoon. Use a kitchen torch to toast the meringue until golden brown (or briefly run it under the oven broiler, watching constantly). Finish with a light sprinkle of flaky sea salt before slicing.

Notes

  • Why it works: Halving the sweet potatoes and roasting them cut-side down creates a steam seal against the pan. This caramelizes their natural sugars while preventing the watery, diluted texture you get from boiling them whole, resulting in a significantly richer pie filling.
  • Make-ahead tip: The pie (without the meringue) can be baked, cooled, and stored in the refrigerator for up to 2 days before serving. Add the meringue and toast it just a few hours before you plan to serve, then return the pie to the refrigerator until serving.
  • Clean-slice trick: For the neatest slices, chill the pie fully before cutting, and dip your knife in hot water (wiping it dry) between each cut to glide through the sticky meringue.
