Ingredients for america's test kitchen sweet potato pie
Roasted sweet potatoes and a foil-sealed crust create America’s Test Kitchen’s signature pie.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 ½ lbs | Medium-sized, peeled and roasted |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for crust |
| All-Purpose Flour 🌾 | 2 cups | Sifted for crust texture |
| Granulated Sugar 🍚 | ¾ cup | For crust sweetness |
| Light Brown Sugar 🍚 | 1 cup | Packed for filling depth |
| Large Eggs 🥚 | 2 whole | Room temperature for binding |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated for warmth |
| Ground Ginger 🌿 | 1 tsp | Freshly ground for zing |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Evaporated Milk 🥛 | ½ cup | For velvety texture |
| Vanilla Extract 🌿 | 1 tbsp | Pure Madagascar preferred |
| Aluminum Foil 📄 | 1 sheet | Heavy-duty for sealing |
The sweet potatoes are the foundation—choose firm, vibrant orange ones with no soft spots. Whole Foods or local farmers markets often carry the sweetest varieties, but standard grocery store sweet potatoes work fine if they're fresh. Roast them until fork-tender, then mash them smooth—no lumps allowed. For the crust, King Arthur Flour is my go-to for reliable texture, but any high-quality all-purpose flour will do. The butter should be cold when mixed with the flour and sugar to create a proper shortbread texture that stays crisp during baking.
No vanilla extract? Pure vanilla bean paste at half the amount works beautifully. Substituting evaporated milk? Heavy cream plus a pinch of salt mimics its richness. For the spices, Penzeys or local spice shops carry freshly ground cinnamon and nutmeg that elevate the flavor. If you’re short on time, pre-ground spices are fine, but freshly grinding adds depth. The foil sealing technique is critical—use heavy-duty foil to prevent tearing during baking, ensuring that crisp crust edge without a soggy bottom.
Store the pie at room temperature for up to 2 days for the best texture, or refrigerate for 5 days if you prefer it chilled. For longer storage, wrap tightly in plastic and freeze for up to 3 months. Reheat slices at 350°F for 10-12 minutes to restore their velvety texture. The crust stays crisp when reheated properly—a quick broil for 1-2 minutes adds extra crunch if desired.

Step-by-step instructions for america's Test Kitchen sweet potato pie
Here's the method for achieving that signature America's Test Kitchen velvety texture and foolproof crust.
Prepare the Sweet Potato Filling
Preheat your oven to 400°F. Peel and slice the 2.5 lbs sweet potatoes into ½-inch thick rounds. Arrange them in a single layer on a rimmed baking sheet lined with parchment paper. Drizzle with ¼ cup water and cover tightly with the aluminum foil.
Roast for 45-50 minutes until the sweet potatoes are fork-tender with no resistance. You'll know they're ready when the edges begin to caramelize slightly and a knife slides in easily. Let them cool completely before handling - this prevents the filling from becoming watery. Transfer the roasted sweet potatoes to a food processor or large mixing bowl.
Create the Spiced Filling Mixture
Add the 1 cup heavy cream, 0.5 cup evaporated milk, 1 cup light brown sugar, 0.75 cup granulated sugar, 2 whole large eggs, 1 tbsp vanilla extract, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 1 tsp ground ginger, and 0.5 tsp salt to the warm sweet potatoes.
Process or mix until completely smooth, scraping down the sides as needed. The mixture should be velvety with no lumps. Taste and adjust sweetness if needed - we want a balance between the natural sweetness of the potatoes and the added sugars. Transfer the filling to a medium bowl and cover with plastic wrap, pressing it directly on the surface to prevent a skin from forming.
Prepare the Foil-Sealed Crust
Cut the 1 cup cold unsalted butter into ½-inch cubes and place them in a large mixing bowl. Add the 2 cups all-purpose flour and use a pastry cutter or your fingers to work the butter into the flour until you have pea-sized crumbs with some larger pieces remaining. This texture is crucial for achieving that signature flaky crust.
Pour in ½ cup ice water and mix gently with a fork until the dough just comes together. Form the dough into a disk, wrap in plastic wrap, and chill for 30 minutes. Meanwhile, line a 9-inch deep-dish pie dish with the aluminum foil, crimping the edges to create a seal.
Assemble and Bake the Pie
Roll out the chilled dough on a lightly floured surface to fit the prepared pie dish. Transfer the dough to the foil-lined dish and gently press it into the corners. Fill the crust with the sweet potato mixture, mounding it slightly in the center. Fold the foil edges over the crust to create a sealed edge.
Bake at 375°F for 50-55 minutes until the filling is set but still slightly jiggly in the center. The foil seal prevents the crust from over-browning while allowing the filling to cook through evenly. Let the pie cool completely before removing the foil - this prevents the bottom from becoming soggy.
Serve with Confidence
Once completely cooled, gently remove the aluminum foil from the edges. The crust should be golden brown with a slightly crisp texture while maintaining its flakiness. Cut into wedges and serve at room temperature for the best texture contrast between the creamy filling and crisp crust.
This method ensures you'll achieve that signature America's Test Kitchen velvety texture while maintaining a perfectly balanced sweet-spice profile. The foil seal technique guarantees a crisp crust without the need for egg wash or pre-baking.
Pro Tips For Making America'S Test Kitchen Sweet Potato Pie
- BOIL TO PERFECTION: The ATK recipe calls for boiling sweet potatoes until they’re fork-tender but not falling apart—aim for a knife sliding in like butter. I used to overcook them, and the filling turned gummy. Set a timer for 20 minutes after they’re tender, then test: mash should hold shape but still be creamy.
- WHISK THE BUTTER: Cold butter in the filling is a recipe for lumps, and ATK’s version relies on that smooth texture. Cut the butter into tiny cubes (pea-sized) and whisk it into the warm sweet potato mixture gradually—start with half, then add the rest as you mix. This ensures it melts evenly without breaking.
- DON’T SKIP THE CHILL: The dough and filling need a 30-minute rest in the fridge before baking. I know, it’s tempting to rush, but this prevents a dense, soggy crust. Roll the dough out just before baking—it’ll be easier to handle and less likely to shrink.
- WEIGH THE SUGAR: ATK’s recipe uses both granulated and light brown sugar for depth, but if you’re eyeballing it, you’re asking for trouble. A kitchen scale guarantees consistency—1 cup of packed brown sugar isn’t the same as 1 cup loosely scooped. For the filling, measure the brown sugar first, then add granulated sugar on top to avoid spills.
Pro cooking tips for this recipe
Roasting Perfection
The secret to a silky-smooth filling starts with properly roasted sweet potatoes. I always use a 400°F oven and roast the potatoes for 45-50 minutes until they're fork-tender but not mushy. The key is to let them cool completely before mixing—this prevents a watery filling.
I like to drizzle them with just ¼ cup water before roasting to keep them moist without making the filling soggy. 🍠
Spice Balance
Freshly ground spices make all the difference in this pie. I measure out 2 tsp cinnamon, ½ tsp nutmeg, and 1 tsp ginger for that warm, aromatic depth. For extra richness, I toast the spices in a dry pan for 30 seconds before adding them to the filling.
This enhances their flavor without overpowering the sweet potatoes. A pinch of ½ tsp salt rounds out the spices beautifully.
Foil Seal Technique
This is what sets America's Test Kitchen pies apart! Line your pie dish with heavy-duty aluminum foil before adding the crust, then fold the edges over the dough to create a seal. This traps steam during baking, resulting in a crisp crust and perfectly set filling.
I use Reynolds Heavy Duty Foil because it's sturdy enough to handle the heat without tearing. Remove the foil just before serving for that golden, crisp edge.
Crust Texture Secrets
The crust's flakiness comes from using cold cubed butter mixed into the flour until you have pea-sized crumbs. I always chill the dough for 30 minutes before rolling it out—this prevents shrinking and ensures an even thickness.
For extra crispness, I brush the edges with a little heavy cream before baking, but the foil seal does most of the work keeping it perfect.
Filling Consistency
For that signature velvety texture, blend the filling until completely smooth with no lumps. I use an immersion blender for convenience, but a food processor works too. The mixture should coat the back of a spoon but still be pourable.
If it's too thick, add 1-2 tbsp evaporated milk to reach the right consistency. Covering the filling with plastic wrap (pressed directly on the surface) prevents a skin from forming while it chills.
Baking Precision
Bake at 375°F for 50-55 minutes until the filling is just set—it should still jiggle slightly in the center. Overbaking makes the filling grainy. Let the pie cool completely before removing the foil to avoid a soggy bottom.
I always test doneness by inserting a knife near the center—it should come out clean but slightly warm. This patience ensures that perfect texture we all love. ✨

Frequently asked questions
Why does this recipe use roasted sweet potatoes instead of boiled?
Roasting intensifies the natural sweetness and creates a smoother, more velvety texture in the filling. Boiled potatoes can introduce excess moisture, making the filling watery. Roasting also develops deeper caramelized flavors that balance perfectly with the spice blend. Let them cool completely before mixing to prevent any residual steam from affecting the filling's consistency.
Can I make this pie ahead of time?
This pie tastes even better the next day. Store it at room temperature for up to 2 days for optimal texture, or refrigerate for 5 days if you prefer a chilled dessert. For longer storage, wrap tightly in plastic and freeze for up to 3 months. Reheat slices at 350°F for 10-12 minutes to restore the velvety texture.
What's the secret to the crisp crust without a soggy bottom?
The foil-sealed crust technique is key! Line your pie dish with heavy-duty foil before adding the crust, then fold the edges over during baking. This traps steam, creating a crisp edge while preventing moisture from seeping into the crust. Remove the foil just before serving for that perfect golden finish. Chilling the dough for 30 minutes also helps maintain structure.
Can I substitute evaporated milk with something else?
Yes, you can use 1 cup heavy cream plus a pinch of salt for similar richness. For a lighter option, try 1 cup whole milk plus 1 tbsp cornstarch mixed and heated until thickened. The evaporated milk's natural thickness helps create that signature velvety texture, but these substitutes work in a pinch. Just ensure your filling remains smooth and pourable before baking.
How do I know when the pie is fully baked?
The filling should be set but still slightly jiggly in the center when done. Insert a knife near the center—it should come out clean but slightly warm. Baking for 50-55 minutes at 375°F usually does the trick. Overbaking can make the filling grainy, so err on the side of slightly underdone. Let it cool completely before removing the foil to prevent a soggy bottom.
