Instructions

1. 1

   Heat the oven

   Preheat the oven to 175°C (350°F) and position a rack in the centre so the pie bakes evenly.

2. 2

   Smooth the potatoes

   Put the mashed sweet potatoes in a food processor or a stand mixer fitted with the paddle attachment. Pulse or beat a few times until silky and free of stringy fibres, then set aside.

3. 3

   Mix the filling

   In a large bowl, combine the sweet potato purée, melted butter, brown sugar, cinnamon, nutmeg, salt, cardamom, ginger, cornmeal, bourbon if using, eggs, evaporated milk and vanilla extract. Mix until smooth and thoroughly combined.

4. 4

   Fill the crust

   Pour the filling into the prepared pie crust. Smooth the surface with an offset spatula or spoon if needed.

5. 5

   Bake the pie

   Bake for 55–60 minutes. Check the crust after 30 minutes and cover it with foil or a pie-crust shield if it is browning too much. The centre should still have a slight wobble when the pie is done.

6. 6

   Cool the pie

   Set the pie on a wire rack for at least 2–3 hours to cool. Cover it with foil and refrigerate until completely chilled; because it contains milk and eggs, keep it refrigerated. Add meringue or whipped cream if desired, then slice and serve.

7. 7

   Set up a bain-marie

   Bring a few inches of water to a simmer in a small saucepan. Put the egg whites, sugar, cream of tartar and salt in a small heatproof bowl, then set it over the pan, making sure the water does not touch the bowl.

8. 8

   Warm the mixture

   Whisk continuously for about 5–6 minutes, until the mixture changes from thick to thin, feels warm and becomes somewhat frothy. Rub a little between your fingers to check that the sugar has dissolved and no granules remain.

9. 9

   Add the vanilla

   Turn off the heat and carefully lift the bowl from the saucepan. Stir in the vanilla bean paste or vanilla extract and whisk to combine.

10. 10

    Whip the meringue

    Transfer the mixture to a stand-mixer bowl or use a handheld mixer. Beat on high for about 5–7 minutes, until fluffy and forming stiff peaks that stand tall without weeping.

11. 11

    Top and toast

    Spread the meringue over the cooled pie. Serve as it is or lightly toast the topping with a kitchen torch.

What is Southern sweet potato pie?

Sweet potato pie is a traditional dessert associated with the American South, made by baking a spiced sweet potato custard in pastry. This version brings together brown sugar, evaporated milk and warm spices, then finishes the pie with a toasted meringue topping.

Smooth filling: puréeing the cooked potatoes helps make the custard silky, while cornmeal adds a little structure. The meringue gives each slice a light, sweet contrast to the dense filling.

Nutrition and macros by portion

The nutrition label shows one serving as written: 575 calories, 7g protein, 80g carbs, 27g fat.

The sweet potato, brown sugar and meringue sugar provide most of the carbohydrates, while the pastry and butter contribute much of the fat. Eggs and evaporated milk add protein, though this dessert is not a major protein source. Pair a slice with fresh fruit or serve it after a meal that includes a substantial protein source.

Choose and prepare the potatoes

Garnet yams: these are a sweet-potato variety, rather than true yams, and are suggested for their rich colour and flavour. Cook, peel and mash them before measuring the amount for the filling.

Fine purée: process or beat the mash until no stringy fibres remain. This extra smoothing makes a noticeable difference to the finished texture.

Build the spiced filling

Brown sugar and butter: the sugar sweetens the potatoes and brings a deeper flavour, while melted butter enriches the custard. Let the butter cool slightly before mixing it with the eggs.

Warm spices: cinnamon and nutmeg lead, with smaller amounts of cardamom and ginger adding complexity. Bourbon is optional, so leave it out if you prefer a straightforward vanilla-and-spice filling.

Watch the bake

Crust check: look in on the pie after 30 minutes, as the pastry edge may brown before the filling is ready. Shield it with foil or a pie-crust shield if needed.

Centre cue: at 55–60 minutes, the middle should have a slight wobble rather than looking completely firm. It will continue to settle as it cools, so avoid baking until the centre is rigid.

Cool before topping

First cooling: leave the pie on a wire rack for at least 2–3 hours. Chilling it completely before adding the meringue helps the topping sit on the filling rather than soften against a warm surface.

Meringue test: keep whisking the egg-white mixture over the simmering water until the sugar feels fully dissolved between your fingers. Then beat it until stiff peaks hold upright.

Make the marshmallow topping

Gentle heat: the bowl should sit above the simmering water without touching it. Whisk the whites and sugar continuously so the mixture warms evenly and does not cook against the bottom of the bowl.

Toasted finish: spread the meringue over the chilled pie and use a kitchen torch for light browning if you like. Keep the flame moving to colour the surface without scorching it.

Serving and timing

Plan ahead: the pie needs a long cooling period after baking, followed by chilling, so allow time before serving. The topping can be added once the filling is fully cool.

On the plate: serve slices on their own or alongside a modest spoonful of whipped cream. Coffee or unsweetened tea makes a good pairing with the sweet, spiced filling.

Recipe notes & tips

• Cool the melted butter slightly before combining it with the eggs.
• Process the sweet potato until smooth to avoid fibrous bits in the filling.
• Check the crust at the 30-minute mark and shield it if it is getting too dark.
• Use a gentle simmer for the meringue bowl and keep the water below its base.
• Rub a little warmed meringue mixture between your fingers to check for undissolved sugar.
• Chill the pie fully before spreading the meringue over it.

Variations

• Skip the bourbon: leave it out for a more classic vanilla-and-spice flavour.
• Use whipped cream: replace the meringue with whipped cream when serving.
• Change the spice balance: adjust the cinnamon, nutmeg, cardamom and ginger to suit your preference.
• Add a toasted finish: lightly brown the meringue with a kitchen torch just before serving.

Common mistakes to avoid

• Stringy filling: process the mashed potatoes until silky before mixing in the other ingredients.
• Overbrowned crust: check it after 30 minutes and shield the edges with foil or a pie-crust shield.
• Overbaked centre: take the pie out when the middle still has a slight wobble.
• Warm topping base: let the pie cool completely before adding the meringue.
• Undissolved sugar: keep whisking over the simmering water until no grains can be felt between your fingers.
• Runny meringue: beat until stiff peaks stand tall before spreading it over the pie.

How to store

Once cooled, cover the pie with foil and keep it refrigerated because it contains milk and eggs. Store leftovers in the fridge and serve chilled, or let a slice stand briefly at room temperature before eating.
