Sweet Potato Pie
yields one nine-inch pie
Thanksgiving is the season not just for turkey but for pies as well, and therein lay my problem. I’ve never liked buying commercial pies because I find them too sweet and cloying; yet I’ve also avoided making pies myself because, like many people, I feared making the dough. So what to do? For a while, I simply let my mother do the Thanksgiving baking. (Having had the turkey wrested from her several years ago, she was glad for this sop.) Over time, though, I realized that I was just worrying too much. I studied the basics of pie-dough creation and found that I could make a decent (if not Parisian) dough with very little fuss. That’s why they call it "easy as pie."
- 1 prebaked nine-inch pie shell (see recipe below)
- 1 1/2-1 3/4 lb sweet potatoes (to yield 2 1/4 c flesh)
- 1 14-oz can sweetened condensed milk (or 3/4 c heavy cream)
- 2 eggs plus 2 egg yolks
- 4 Tbs unsalted butter, melted
- 1 c sugar
- 1 tsp vanilla extract
- 1/2 tsp ground cinnamon
- 1/4 tsp ground nutmeg
- 1/8 tsp ground cloves
1. Prick the ends of the sweet potatoes with a fork and roast them at 425 degrees Fahrenheit on a foil-lined baking sheet, turning them after about half an hour. Continue roasting until the skin separates from the flesh and the flesh itself becomes very soft, about 60-90 minutes depending on the size of the potatoes. Let cool.
2. Lower the oven temperature to 350 degrees Fahrenheit.
3. Remove the skin from the roasted potatoes (it should slip off easily), place the flesh in a large mixing bowl, and mash well. Add the remaining ingredients and stir with a whisk or spatula until well blended and smooth. Transfer the filling to the prebaked pie shell.
4. Bake until the filling sets, about 45-50 minutes. Cool before serving.

Tips
* Most recipes call for the sweet potatoes to be boiled, as you would for regular mashed potatoes. But I don’t like having to peel them, and I prefer the slightly caramelized taste one gets from roasting them. Just make sure you leave them in the oven long enough for them to become completely soft.
* You can roast the potatoes several days in advance and refrigerate them until you’re ready to make the pies.
* Although cinnamon, cloves, and nutmeg are the traditional spices for sweet potato pie, there are alternatives. Some people use ground ginger, but I don’t think the flavor comes through very well in the finished pie. One option I do endorse is ground cardamom. It may sound odd, but just a hint (about an eighth of a teaspoon) makes for a heady pie.
* A good way to test whether the pie is done is to give it a little shake. If the filling slides to one side, it needs more baking time; if the center jiggles a little but holds its shape, it’s done.
Pie Shell yields one nine-inch pie shellIf you plan on making two shells, just double the amounts rather than making two batches. The dough ball can easily be cut in half before rolling.
- 1 c flour
- 2 Tbs vegetable shortening, chilled
- 3 Tbs unsalted butter, chilled
- 1/2 tsp kosher salt
- 2-4 Tbs ice water
1. Preheat the oven to 350 degrees Fahrenheit.
2. Measure the flour and shortening into the bowl of a food processor fitted with a steel blade. Chop the butter into half-inch cubes and add them to the flour and shortening. Pulse the machine until the dough reaches the consistency of a course meal with some pea-sized pieces, about 20-30 seconds. Add the salt to the ice water and, with the machine running, drizzle the water through the feed tube until the dough comes together to form a ball. Turn out the dough onto some plastic wrap, wrap it securely, and chill in the refrigerator for at least an hour (or overnight).
3. On a lightly floured surface, roll out the dough to form a circle large enough to cover the pie plate with a little overhang (a total diameter of about eleven inches). Transfer the dough circle to the pie plate, folding and crimping the overhanging edges. Refrigerate for at least fifteen minutes.
4. Cover the pie shell with aluminum foil, weighing down the foil with rice, beans, or pie weights. Bake until the dough sets, about 15 minutes. Remove the weighted foil and continue baking until the shell turns a light golden brown, about another 10-12 minutes. Remove and let cool, pricking any bubbles that may have formed with a fork to let the crust settle down.

Dough Tips
* The ideal pie crust is both tender and flaky. Pastry chefs achieve these two qualities with skilled kneading that creates layers (or sheets) of fat without overworking the dough. (Overworked dough turns tough and spongy, like bread.) My food processor method doesn’t yield dough as tender as an English scone or as flaky as a croissant, but it does produce a consistently good result without the need of a pastry tutor.
* When making pie dough, you want to keep your ingredients and equipment as cold as possible. Otherwise, the butter melts a little, resulting in a rubbery dough.
* You want to add the water to the dough fast enough so that the food processor doesn’t overwork the dough yet slow enough so that you add the least amount necessary to bring the dough together. I usually add a couple of tablespoons quickly and then drip in any more that’s needed. After a try or two, you’ll get the hang of it.
* To roll a circular crust, first shape the dough into a flat disk. Then roll the dough out from the center. After each roll, gently lift the dough and give it a quarter turn, reflouring the rolling surface and pin as necessary to prevent sticking and tearing. If the dough does tear, simply pinch it together and keep rolling. Do not start from the beginning because this will overwork the dough.
* An easy way to transfer the dough from the rolling surface to the pie plate is to roll it up onto the pin and then unroll it over the plate.
* If your circle is a little wonky and there’s a gap in one section of edge, don’t worry. Just pinch off some overhanging dough from another section and use it as a patch.
Listener Feedback
Jay DiPucchio of Turners Falls, Massachusetts, sent along this recipe for Sweet Potato Pecan Pie, which he calls “even more life threatening.” It makes enough for a nine-inch pie shell.
Sweet Potato Foundation
- 1 c cooked sweet potato flesh
- 4 Tbs brown sugar
- 2 Tbs white sugar
- 2 Tbs heavy cream
- 1 Tbs unsalted butter, softened
- 1 egg, whipped into a frenzy
- 1 Tbs vanilla extract
- 14 tsp kosher salt
- 14 tsp ground cinnamon
- 14 tsp groud allspice
- 1/8 tsp ground nutmeg
Pecan Roof
- 34 c white sugar
- 34 c dark corn syrup
- 2 eggs beaten
- 1 1/2 Tbs unsalted butter, melted
- 2 tsp vanilla extract
- a pinch of salt
- a pinch of ground cinnamon
- 1 c pecans, lightly toasted
1. Whip the sweet potato foundation ingredients together until they’re almost fluffy, then set aside. (I prefer doing this by hand so that an occasional bit of reluctant sweet potato remains for texture, but electric mixers are acceptable in some circles.)
2. Reserving the pecans, stir together all of the other ingredients for the pecan roof until the mixture is smooth. Chop up thre-quarters of the pecans and add them to the roof mixture.
3. Transfer the foundation to the pie shell, smoothing the top. Then add the roof, topping the whole thing off with the reserved pecans. Bake at 325 degrees Fahrenheit for 75 minutes and then begin checking regularly to see whether the pie is done. (It puffs up quite a bit, so you should include a spill pan under the pie plate.) Cool before serving (preferably overnight on the porch in the November air).
