Ingredients for america's test kitchen sweet potato pie
These 14 ingredients transform humble sweet potatoes into America's Test Kitchen's signature crack-free, velvety pie.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 lbs | Firm, orange-fleshed like Beauregard |
| All-Purpose Flour 🌾 | ½ cup | For thickening filling |
| Granulated Sugar 🍚 | 1 ½ cups | Adjust to taste for sweetness |
| Brown Sugar 🍯 | ½ cup | Packed, for caramel notes |
| Evaporated Milk 🥛 | 1 cup | Full-fat for creaminess |
| Heavy Cream 🥛 | ½ cup | Full-fat for velvety texture |
| Large Eggs 🥚 | 2 whole | Room temperature for blending |
| Unsalted Butter 🧈 | ½ cup | Cubed, cold for crust |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated for depth |
| Ground Ginger 🌿 | 1 tsp | Freshly ground for warmth |
| Salt 🧂 | ½ tsp | Kosher salt preferred |
| Pie Crust 🥧 | 1 pre-made | Classic flaky or vegan alternative |
| Vanilla Extract 🌸 | 1 tbsp | Pure vanilla preferred |
The sweet potatoes are non-negotiable—Beauregard or similar firm, orange-fleshed varieties give the best texture. Costco or Trader Joe's usually stock them year-round, but check the produce section for firm, unblemished tubers. The crust matters too: for classic flaky, Pillsbury or store-bought works, but if you're going vegan, Bob's Red Mill or Whole Foods carry excellent plant-based options. The spices? Freshly ground nutmeg and ginger make all the difference—Penzeys or bulk bins at natural markets are your best bet for quality.
No brown sugar? Substitute with white sugar plus 1 tsp molasses for depth. Running low on evaporated milk? Heavy cream plus 1 tsp lemon juice mimics the tang. The crust can be homemade too—just use your favorite recipe, but keep it cold when rolling to prevent shrinking. For extra richness, add 1 tbsp cornstarch to the filling to prevent cracks. And if you're vegan, aquafaba (chickpea brine) replaces eggs perfectly in the filling—just whisk it vigorously for volume.
Sweet potatoes keep 1 week in the pantry, filling ingredients last 3 months in the fridge. The crust? Use within 2 days of purchase for best flakiness. For make-ahead magic, assemble the pie 1 day ahead—cover and refrigerate. The filling can be pre-cooked and stored 3 days before baking. Slice and serve warm for that signature creamy texture—every bite will be worth the wait!

Step-by-step instructions for america's Test Kitchen sweet potato pie
Here's the foolproof method for a silky, crack-free pie that'll have everyone begging for seconds.
👨🍳 Step 1: Roast the Sweet Potatoes Until Tender
Preheat your oven to 400°F. Pierce the 2 lbs sweet potatoes all over with a fork, then place them on a baking sheet. Roast for 45-60 minutes until completely tender when pierced with a knife—you should be able to twist the fork easily through the center.
Here's the thing—I like to test doneness by squeezing the potatoes gently. When they're ready, they'll feel soft all the way through with no resistance. Let them cool slightly before handling, then scoop out all the flesh, discarding the skins. You should have about 2 cups of cooked sweet potato.
🍳 Step 2: Make the Silky Filling
In a large bowl, combine the cooked sweet potato with 1.5 cups granulated sugar, 0.5 cup brown sugar, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 1 tsp ground ginger, 0.5 tsp salt, and 1 tbsp vanilla extract. Mash everything together with a potato masher or fork until completely smooth.
Now for the magic—whisk in 1 cup evaporated milk, 0.5 cup heavy cream, 2 whole large eggs, and 0.5 cup unsalted butter (melted and cooled slightly). The mixture should be thick but pourable. I always taste it at this point and adjust sweetness if needed—some sweet potatoes vary in natural sweetness.
🥘 Step 3: Thicken the Filling Properly
In a separate bowl, whisk together 0.5 cup all-purpose flour with 1 tablespoon cold water to make a smooth paste. Slowly whisk this into the sweet potato mixture while stirring constantly. The goal is to create a thick, smooth filling that coats the back of a spoon but still pours easily.
This flour slurry is what prevents cracks in your pie. Don't skip it—it's the secret to that velvety texture. The filling should now be thick enough to hold its shape when dropped from a spoon but still flow smoothly when poured.
🔥 Step 4: Assemble and Bake to Perfection
Roll out the pre-made pie crust to fit a 9-inch pie dish, leaving a ½-inch overhang. Pour the filling into the crust, then fold the overhang under and crimp the edges. Cut a few slits in the top to allow steam to escape—this prevents the crust from puffing up.
Bake at 375°F for 50-60 minutes until the filling is set but still slightly jiggly in the center (it'll firm up as it cools). The edges should be golden brown but not over-browned. Here's my pro tip: If the crust starts browning too quickly, tent it loosely with foil after 30 minutes.
⏰ Step 5: Cool and Serve for Maximum Flavor
Let the pie cool completely on a wire rack before slicing—this prevents the filling from running everywhere. The pie will be at its peak when it's just slightly warm, with that perfect balance of creamy texture and spiced sweetness.
Cut into wedges and serve with whipped cream or a dollop of vanilla ice cream. The secret to serving this pie right is patience—waiting for it to cool gives the flavors time to meld perfectly. Trust me, every bite will be worth the wait!
Pro Tips For Making America'S Test Kitchen Sweet Potato Pie
- Boil Potatoes Until Fork-Tender: I learned this the hard way—undercooked sweet potatoes turn your pie filling into a watery mess. Boil them until they’re so soft a fork slides right in (about 20-25 minutes), then mash them smooth. No lumps, no regrets.
- Toast the Flour First: Skip the flour straight from the bag—it’s bland and gummy. Toast 2 tablespoons in a dry pan over medium heat for 2-3 minutes until it smells nutty. This makes the crust richer and prevents that chalky aftertaste. (Yes, even if you’re impatient like me.)
- Don’t Overmix the Filling: The second you add the evaporated milk, stop stirring. Overmixing incorporates air, which makes the pie dense and gummy. Just fold it in until just combined—think "marbled," not "smooth." Your future self will thank you.
- Use Cool Sweet Potatoes: Hot mashed sweet potatoes make the filling watery as it cools. Let them sit in the pot, covered, for 10 minutes after boiling before draining and mashing. This guarantees a thick, velvety texture—not a puddle. (I know, I know, but trust the process.)
Pro cooking tips for this recipe
Sweet Potato Prep
Start with the right sweet potatoes—Beauregard or Jewel varieties are ideal for their dry, starchy flesh. Pierce them all over with a fork before roasting to prevent explosions, then bake at 400°F for 45-60 minutes until fork-tender.
Let them cool completely before scooping out the flesh—this prevents filling from becoming watery. I always test doneness by squeezing gently; they should feel completely soft with no resistance. 🍠
Filling Thickening
The flour slurry is the secret to crack-free filling. Whisk ½ cup all-purpose flour with 1 tbsp cold water until smooth, then gradually whisk it into the warm sweet potato mixture. This creates a stable, velvety texture that won't shrink or crack during baking.
For extra insurance, chill the filling for 30 minutes before pouring into the crust—this helps it set more evenly. 🥄
Crust Handling
Use a pre-made crust (like Pillsbury) for foolproof results, but if making your own, keep it cold when rolling to prevent shrinking. Press it gently into the pie dish, then trim excess to ½-inch overhang.
For a vegan option, Bob's Red Mill plant-based crust works beautifully—just blind-bake it for 10 minutes at 375°F before adding filling to prevent sogginess. 🥧
Baking Precision
Bake at 375°F for 50-60 minutes until the filling is set but still slightly jiggly in the center. If the crust browns too quickly, tent it loosely with foil after 30 minutes.
The filling should be 160°F internally when done—use a thermometer for accuracy. Let it cool completely before slicing, or the filling will run everywhere. 🔥
Spice Balance
Freshly ground spices make all the difference—Penzeys or store-brand bulk spices work best. Start with 2 tsp cinnamon, ½ tsp nutmeg, and 1 tsp ginger, then adjust to taste.
For depth, add 1 tbsp vanilla extract and a pinch of salt to enhance the sweetness. If your filling tastes too tart, add 1-2 tbsp more sugar before baking. 🌿
Make-Ahead Magic
Assemble the pie 1 day ahead and refrigerate uncovered for 12 hours to let flavors meld. Bake straight from the fridge—no need to thaw. For extra richness, brush the crust with egg wash before baking.
Store leftovers in an airtight container for up to 4 days, or freeze for 3 months. Reheat slices at 350°F for 10 minutes to restore creaminess. ⏰

Frequently asked questions
Why does America's Test Kitchen's recipe use roasted sweet potatoes instead of boiled?
Roasting intensifies the natural sweetness and creates a smoother texture in the filling. Boiled sweet potatoes can become watery, which dilutes the spice flavors and makes the pie filling too thin. The roasting method also helps break down the starches for that signature velvety consistency.
Can I make this pie without a traditional crust?
For a crustless version, bake the filling in a 9-inch oven-safe dish and serve warm. You can also try a graham cracker or pecan crust by pressing crushed cookies into the bottom of the dish before adding the filling. Just reduce baking time by 10-15 minutes since there's no crust to absorb heat.
How do I prevent cracks in my sweet potato pie?
The flour slurry is key—whisk ½ cup flour with 1 tbsp cold water before adding it to the filling. Also, chill the filling for 30 minutes before baking, and avoid overbaking. The filling should be set but still slightly jiggly when done.
Can I substitute regular potatoes for sweet potatoes?
No, this recipe requires sweet potatoes—their natural sweetness and moisture content are essential. Regular potatoes lack the sugar and starch balance needed for the perfect texture. If you must substitute, try yams, but adjust the sugar to 1 cup total (reduce by ½ cup) since yams are sweeter.
How long can I store individual slices?
Store slices in an airtight container in the fridge for up to 4 days. For longer storage, freeze slices for 3 months. To reheat, warm at 350°F for 10-15 minutes until the filling is creamy again. The texture may be slightly firmer after freezing, but it restores beautifully with gentle warming.
