Ingredients for america's test kitchen sweet potato pie
Sweet potatoes, warm spices, and a golden lattice crust—everything you need for a foolproof showstopper.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 lbs | Medium, peeled and cubed |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for lattice |
| All-Purpose Flour 🌾 | 2 ½ cups | Plus 1 tbsp for dusting |
| Granulated Sugar 🍚 | 1 ½ cups | Divided for filling and lattice |
| Brown Sugar 🍚 | ½ cup | Packed for filling |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Evaporated Milk 🥛 | 1 cup | Full-fat for creaminess |
| Ground Cinnamon 🌿 | 2 tbsp | Freshly ground preferred |

The sweet potatoes are non-negotiable here—orange-fleshed varieties like Beauregard give the best texture. Trader Joe's and Whole Foods usually carry them year-round, but local farmers markets have the freshest stash in fall. Peeled and cubed, they roast until tender—no mushy filling here. For the spices, Penzeys is my go-to for cinnamon and nutmeg, but the grocery store stuff works fine if it's labeled 'ground fresh.' The key is freshness: if your nutmeg smells like sawdust, toss it. The lattice crust? That's where the magic happens—cold butter and brown sugar make it crispy, while the egg wash gives that golden sheen.
No vanilla extract? Vanilla bean paste works just as well, or scrape seeds from a pod. Short on brown sugar? White sugar plus 1 tsp molasses mimics the depth. The lattice design might seem fussy, but it's just cutting dough strips and weaving them—watch a YouTube tutorial once, and you'll have it down. For the filling, if you're worried about lumps, blend the roasted sweet potatoes until completely smooth before adding other ingredients. And trust me on the evaporated milk—it's richer than regular milk and keeps the filling creamy.
Roasted sweet potatoes keep in the fridge for 5 days if wrapped tightly, but make the filling fresh for best results. The lattice dough can be prepped a day ahead and chilled—wrap it in plastic to prevent drying. This pie tastes even better the next day, so bake it ahead for parties. Store leftovers covered at room temp for 2 days or freeze the whole pie for 3 months. The crust stays crispy if you reheat slices in a 350°F oven for 5 minutes—just like fresh out of the oven.

Step-by-step instructions for sweet potato pie with golden lattice top
Here's how to create that perfect balance of creamy filling and crispy lattice crust.
🍳 Step 1: Cook the Sweet Potatoes to Silkiness
Preheat your oven to 400°F. Place the 2 lbs peeled and cubed sweet potatoes in a large baking dish and cover tightly with foil. Add ½ cup water to the dish—this helps steam the potatoes for even cooking. Bake for 45-50 minutes until a knife slides in easily with no resistance.
Here's the thing—sweet potatoes vary in moisture content. If they're not tender after 50 minutes, give them another 10 minutes. Overcooking turns them mushy, but undercooked cubes make your filling grainy. Once done, drain them thoroughly in a colander and let them cool slightly before handling.
👨🍳 Step 2: Make the Creamy Spiced Filling
In a large mixing bowl, combine the cooled sweet potatoes with 1.5 cups granulated sugar, ½ cup packed brown sugar, 2 whole eggs, 1 cup evaporated milk, 2 tbsp ground cinnamon, ½ tsp ground nutmeg, ½ tsp ground ginger, ½ tsp salt, and 1 tsp vanilla extract. Use a hand mixer or stand mixer to beat everything together on medium speed for 2 minutes.
You'll notice the mixture thickens as you mix—this is normal. The sweet potatoes release starch as they cool, which helps create that signature creamy texture. The spices should be fully incorporated, with no visible streaks of cinnamon or nutmeg. Taste a spoonful and adjust sweetness if needed (I usually add 1-2 tbsp more sugar for perfect balance).
🥘 Step 3: Assemble the Pie Crust
Roll out 2 cups of the pie dough (using 1½ cups all-purpose flour plus 1 tbsp for dusting) to fit a 9-inch pie dish, leaving a ½-inch overhang all around. Trim the edges to ¼-inch width and crimp decoratively. Chill the crust in the freezer for 15 minutes while you prepare the lattice.
For the lattice, roll out the remaining 1 cup pie dough (using the remaining 1 cup flour) into a 12x16-inch rectangle. Cut into 1-inch strips using a pizza cutter or sharp knife. Here's where it gets fun—weave the strips over the chilled crust in a classic lattice pattern, leaving the center open for steam to escape.
🔥 Step 4: Bake with Precision for Perfect Texture
Pour the filling into the lattice-topped crust, mounding it slightly in the center. Cut the ½ cup cold cubed butter into small pieces and arrange them on top of the filling. This creates steam pockets that make the lattice extra crispy. Bake at 375°F for 50-55 minutes until the lattice is deep golden brown and the filling is just set (it'll jiggle slightly in the center).
Real talk: don't open the oven door early to check. The temperature drop causes the lattice to soften. If it's browning too quickly, tent loosely with foil after 30 minutes. The pie is done when the filling pulls away from the edges just slightly and the lattice has crisped to a beautiful golden color.
⏰ Step 5: Rest and Serve for Maximum Enjoyment
Let the pie cool completely on a wire rack for at least 2 hours—this is crucial for the filling to set properly and the lattice to crisp up fully. I know it's tempting to slice into warm pie, but patience here makes all the difference. The contrast between the creamy, spiced filling and the crisp lattice is what makes this pie special.
Slice with a sharp knife and serve with whipped cream or vanilla ice cream. Each bite should deliver that perfect combination of silky sweet potato filling and shatteringly crisp lattice top. Store leftovers covered at room temperature for up to 3 days or refrigerate for up to 5 days (though it rarely lasts that long!).
Pro Tips For Making America'S Test Kitchen Sweet Potato Pie
- BOIL AND MASH SMOOTH: This recipe relies on silky-smooth sweet potato purée—don’t skip the double-boiling step. After roasting, mash the potatoes while hot, then spread them on a tray and microwave for 30 seconds to break down the fibers completely. (Yes, it’s weird, but it works—your filling will be velvety, not grainy.)
- WEIGH THE SUGAR: Use a kitchen scale for the brown and granulated sugar—this recipe’s balance depends on precise measurements. Spooning sugar from the bag leads to inconsistencies, especially when adjusting for sweetness. (I learned this the hard way after making two pies that tasted off.)
- DON’T OVERMIX THE CRUST: The crust’s secret is in the butter—cut it into the flour just until it resembles coarse crumbs. Overworking it turns the dough into a paste, and the result is a tough, dense crust instead of a flaky one. (Your future self will thank you for resisting the urge to fully incorporate.)
- BAKE LOW AND SLOW: Preheat the oven to 350°F and bake the pie on the lower rack. The recipe’s instructions matter here—high heat causes the crust to brown too quickly while the filling stays undercooked. (I was skeptical until I tried it—now I never rush it.)
Best sauces and condiments for these flavors
Classic Whipped Cream
No sweet potato pie is complete without a dollop of whipped cream on top. I use heavy whipping cream (not light cream) and fold in 1 tbsp powdered sugar plus ½ tsp vanilla extract for the perfect sweetness level.
Chill your bowl and beaters first—this helps the cream whip to stiff peaks in just 2-3 minutes. For extra flair, dust with ground cinnamon or a pinch of nutmeg to echo the pie's spices. 🥛
Vanilla Bean Ice Cream
Creamy vanilla ice cream is the ultimate pairing—its cool, rich texture contrasts beautifully with the warm pie. I recommend Häagen-Dazs Vanilla Bean for its ultra-smooth consistency, but homemade works too.
For a quick version, blend 2 cups heavy cream, 1 cup whole milk, ¾ cup sugar, and 2 vanilla beans (scraped) with 4 egg yolks, then churn in an ice cream maker. The vanilla flavor should complement, not overpower, the pie's cinnamon notes. 🍦
Spiced Caramel Sauce
For a gourmet touch, drizzle the pie with a warm spiced caramel sauce made with 1 cup brown sugar, ½ cup heavy cream, 2 tbsp butter, and 1 tsp cinnamon. Simmer until the sugar dissolves, then whisk in the cream and butter until smooth.
Let it cool slightly before drizzling—it should coat the back of a spoon but not be runny. This adds a luxurious sweetness that cuts through the pie's richness. 🍯
Salted Caramel Drizzle
If you love the contrast of sweet and salty, try a salted caramel drizzle. Melt ½ cup caramel sauce (store-bought or homemade) with 1 tbsp butter, then stir in ¼ tsp flaky sea salt.
Drizzle over slices just before serving—it enhances every bite with a sophisticated finish. I like Maldon sea salt for its delicate crunch. 🧂
Coconut Whipped Cream
For a tropical twist, swap regular whipped cream for coconut whipped cream. Whip 1 can (13.5 oz) chilled full-fat coconut milk (refrigerate overnight) until fluffy, then fold in 1 tbsp powdered sugar and ½ tsp vanilla.
The coconut flavor pairs surprisingly well with the warm spices in the pie, adding a creamy, slightly exotic note. 🥥
Caramelized Banana Topping
Slice 2 ripe bananas into rounds and caramelize them in a pan with 1 tbsp butter and 1 tbsp brown sugar over medium heat for 2-3 minutes** until golden. Arrange them on top of the pie before serving—their natural sweetness and soft texture make an unexpected but delicious contrast. 🍌

Frequently asked questions
Can I make this sweet potato pie ahead of time?
This pie actually tastes better the next day as the flavors meld. Bake it 24 hours ahead and store it at room temperature in an airtight container. For longer storage, refrigerate for up to 5 days or freeze the whole pie for 3 months. The lattice stays crispy if you reheat slices in a 350°F oven for 5 minutes—just like fresh out of the oven.
What's the secret to a crispy lattice crust?
The magic is in the butter and baking time! Use cold cubed butter on top of the filling to create steam pockets that crisp the lattice. Bake at 375°F for 50-55 minutes—don't peek early! If browning too fast, tent loosely with foil after 30 minutes. The crust should be deep golden brown with no soggy spots.
Can I substitute regular potatoes for sweet potatoes?
No—this recipe relies on the natural sweetness and texture of sweet potatoes. Regular potatoes will make the filling too starchy and watery. If you're out of sweet potatoes, try yams (like Beauregard variety), but they won't be identical. For a vegan version, replace eggs with flax eggs and use coconut milk instead of evaporated milk.
Why does my filling look grainy?
Grainy filling usually means the sweet potatoes weren't cooked enough or cooled properly. Always roast until a knife slides in easily, then cool completely before blending. For extra smoothness, blend the roasted sweet potatoes until completely smooth before adding other ingredients. Also, make sure your eggs and evaporated milk are room temperature.
What's the best way to serve this pie?
Serve warm or at room temperature with classic whipped cream or vanilla ice cream. For extra flair, dust with cinnamon or drizzle with spiced caramel sauce. The contrast between the creamy filling and crisp lattice is what makes this pie special—don't skip the toppings! Each slice should have that perfect balance of textures.
