Quick Recipe Version (TL;DR)

Yield: 1 (9-inch) pie, about 8 servings
Prep Time: 30 minutes (active)
Cook Time: 1 hour 20 minutes
Total Time: 1 hour 50 minutes (plus 2 hours cooling)

Quick Ingredients

1 single 9-inch pie crust (homemade or store-bought), chilled
1 1/2 lb orange-flesh sweet potatoes (about 3 medium)
4 tbsp unsalted butter, melted and slightly cooled
1/2 cup packed light brown sugar
1/4 cup granulated sugar
2 large eggs + 1 large egg yolk, room temperature
2/3 cup evaporated milk (5 fl oz) or heavy cream
1 tsp pure vanilla extract
1 tsp ground cinnamon
1/4 tsp ground nutmeg
1/4 tsp ground ginger
1/8 tsp ground allspice (optional)
1/2 tsp fine sea salt
1 cup cold heavy cream
2 tbsp powdered sugar
1/2 tsp vanilla extract (for whipped cream)

Do This

1) Roast whole sweet potatoes at 400°F (200°C) for 45–60 minutes until very tender; cool, peel, and mash until smooth.
2) Reduce oven to 375°F (190°C). Fit chilled pie dough into a 9-inch pie dish, crimp edges, chill 15 minutes, then blind-bake 20–22 minutes until just set and lightly golden.
3) Whisk mashed sweet potato with melted butter, sugars, eggs, yolk, evaporated milk (or cream), vanilla, spices, and salt until silky and well combined.
4) Pour filling into warm blind-baked crust, smooth the top, and tap gently to release air bubbles.
5) Bake at 375°F (190°C) for 40–50 minutes until the edges are set and the center has a slight wobble; shield crust with foil if it browns too quickly.
6) Cool pie completely (at least 2 hours). Whip cream with powdered sugar and vanilla to soft peaks.
7) Slice cooled pie and serve each piece with a generous dollop of lightly sweetened whipped cream.

1/2 cup (100 g) packed light brown sugar
1/4 cup (50 g) granulated sugar
2 large eggs, room temperature
1 large egg yolk, room temperature
2/3 cup (160 ml) evaporated milk (5 fl oz) or heavy cream

1 cup (240 ml) cold heavy cream
2 tbsp powdered sugar
1/2 tsp pure vanilla extract

Step-by-Step Instructions

Step 1: Roast the sweet potatoes for deep flavor

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or foil for easy cleanup. Pierce each sweet potato several times with a fork and place them on the prepared sheet.

Roast for 45–60 minutes, turning once or twice, until a knife slides through the center with almost no resistance and the skins are starting to wrinkle and caramelize. Larger potatoes may take a few extra minutes. Remove from the oven and let cool until they are comfortable to handle, about 15–20 minutes.

Once cool enough, peel off and discard the skins. Mash the sweet potato flesh thoroughly in a bowl until very smooth, or press it through a sieve or use a food processor for an ultra-silky texture. Measure out 2 packed cups (about 450 g) of mashed sweet potato for the filling and set aside.

Step 2: Make the flaky pie crust

If using store-bought pie dough, skip to Step 3. To make the crust from scratch, whisk together the flour, salt, and sugar in a medium bowl. Add the cold butter cubes and cut them into the flour using a pastry cutter, two knives, or your fingertips until the mixture looks like coarse crumbs with some pea-sized butter pieces remaining.

Sprinkle in 3 tbsp of ice-cold water and gently toss with a fork until the dough clumps together when squeezed. If it is still dry, add up to 1 additional tablespoon of water, a teaspoon at a time. Turn the dough onto a lightly floured surface and gently press it into a disk without overworking it. Wrap in plastic wrap and chill for at least 1 hour (or up to 2 days) before rolling.

Step 3: Roll, fit, and blind-bake the crust

Reduce the oven temperature to 375°F (190°C). On a lightly floured surface, roll the chilled dough into a 12-inch circle, about 1/8 inch thick. Carefully transfer it to a 9-inch pie dish, easing it into the corners without stretching. Trim excess dough to leave about 1 inch overhang, fold it under, and crimp the edges decoratively.

Prick the bottom of the crust lightly with a fork. Place the pie dish in the refrigerator for 15 minutes to firm up the dough, which helps prevent shrinking. Line the chilled crust with parchment paper or foil, then fill it with pie weights or dried beans, spreading them evenly.

Bake at 375°F (190°C) for 15 minutes. Carefully lift out the parchment and weights, then return the crust to the oven and bake for another 5–7 minutes, until the bottom looks just set but only lightly golden (it will bake more with the filling). Set the crust aside while you prepare the filling. Keep the oven at 375°F (190°C).

Step 4: Make the silky spiced sweet potato filling

In a large bowl, whisk the warm mashed sweet potato with the melted butter until completely combined and smooth. Add the brown sugar and granulated sugar and whisk until the mixture looks glossy and uniform.

Add the eggs and egg yolk and whisk until fully incorporated and slightly thickened. Pour in the evaporated milk (or heavy cream), vanilla, cinnamon, nutmeg, ginger, allspice (if using), and salt. Whisk until the filling is very smooth, with no streaks of egg or dairy remaining. If you want an ultra-smooth texture, you can briefly blend the filling with an immersion blender.

Step 5: Fill the crust and bake the pie

Place the blind-baked crust on a rimmed baking sheet to catch any spills and make it easier to move. Pour the sweet potato filling into the warm crust, smoothing the top with a spatula. Gently tap the pan on the counter a couple of times to release any air bubbles.

Bake at 375°F (190°C) for 40–50 minutes. The pie is done when the edges are set and slightly puffed, and the center still has a gentle wobble when you jiggle the pan (like gelatin). If the crust edges are browning too quickly, tent them with strips of foil or a pie shield during the last 15–20 minutes of baking.

Remove the pie from the oven and place it on a wire rack. Cool completely at room temperature, at least 2 hours, so the filling can finish setting before slicing.

Step 6: Whip the cream and serve

Just before serving, make the whipped cream. In a chilled bowl, combine the cold heavy cream, powdered sugar, and vanilla extract. Whip with a hand mixer, stand mixer, or balloon whisk until soft peaks form and the cream holds its shape but still looks pillowy and smooth. Do not overbeat.

Slice the fully cooled sweet potato pie with a sharp knife, wiping the blade clean between cuts for neat slices. Serve each slice with a generous dollop or swirl of the lightly sweetened whipped cream. If you like, finish with a tiny pinch of cinnamon or nutmeg on top of the cream for a pretty, fragrant touch.

Pro Tips

Roast, do not boil: Roasting the sweet potatoes concentrates their natural sweetness and keeps the filling from becoming watery, which is key for a silky but sliceable pie.
Use warm sweet potatoes in the filling: Slightly warm mash blends more easily with butter and sugar, giving a smoother, more velvety texture.
Do not overbake: Pull the pie when the center still has a soft wobble; it will finish setting as it cools. Overbaking can cause cracks and a dry texture.
Protect the crust: Keep an eye on the crust edges and cover with foil if they are browning faster than the filling is setting.
Chill for cleaner slices: For picture-perfect slices, chill the cooled pie in the fridge for 1–2 hours, then let it sit at room temperature for about 20 minutes before serving.

Variations

Pecan-crunch topping: Sprinkle 1/2 cup chopped pecans mixed with 2 tbsp brown sugar over the filling halfway through baking for a crunchy, nutty top layer.
Brown butter twist: Brown the 4 tbsp of butter for the filling until golden and nutty, then cool slightly before mixing in. This adds a deep, toasty flavor.
Spice it up: For a bolder spice profile, increase cinnamon to 1 1/2 tsp and ginger to 1/2 tsp, and add a pinch of cloves.

Storage & Make-Ahead

Sweet potato pie is very make-ahead friendly. Once the pie has cooled completely, cover it loosely with foil or plastic wrap and refrigerate for up to 3 days. For the best texture, let refrigerated pie sit at room temperature for 30–45 minutes before serving.

You can prepare the pie crust dough up to 2 days in advance and keep it chilled, or freeze the unbaked dough disk for up to 2 months (thaw overnight in the refrigerator before rolling). Roasted, mashed sweet potatoes can be made 1–2 days ahead and refrigerated in an airtight container.

Whipped cream is best freshly whipped, but you can whip it a few hours in advance and refrigerate it; briefly re-whisk by hand if it softens. Leftover slices of pie should be stored covered in the refrigerator. For longer storage, wrap slices well and freeze for up to 2 months; thaw overnight in the refrigerator.
