This sweet potato pie recipe with sour cream delivers the perfect balance of creamy filling and spiced crust—no one will guess it's secretly healthier. The sour cream creates that signature velvety texture while keeping the pie rich and moist, not dense.
I've perfected this version after years of testing, and it's become my go-to for holidays and cozy weeknight desserts.
The secret lies in the filling: mashed sweet potatoes blended with eggs, brown sugar, and a blend of warm spices like cinnamon, nutmeg, and ginger. The sour cream adds that signature tang and tenderness that makes this pie stand out from the classic version.
Baking it in a 9-inch pie crust ensures a flaky, golden base that holds up to every forkful.

The best part? It's foolproof—no one will believe how simple it is to achieve restaurant-quality results at home.
Serve it warm with a scoop of vanilla ice cream or whipped cream for the full experience. You can also experiment with variations like adding bourbon for depth or pumpkin spice for extra autumnal flavor. Here's everything you need to make it happen!
Ingredients for sweet potato pie recipe with sour cream
Sweet potatoes, sour cream, and warm spices make this pie creamy, spiced, and foolproof.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 lbs | Peeled and boiled until tender |
| Sour Cream 🥛 | 1 cup | Full-fat for best texture |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Light Brown Sugar 🍚 | 1 cup | Packed firmly |
| Granulated Sugar 🍬 | ½ cup | For balance |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated nutmeg |
| Ground Ginger 🌶️ | 1 tsp | For warmth |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Vanilla Extract 🌸 | 1 tbsp | Pure vanilla preferred |
| Unsalted Butter 🧈 | ½ cup | Melted, cooled slightly |
| All-Purpose Flour 🌾 | ¼ cup | For thickening |
| Unbaked Pie Crust 🥧 | 1 whole | 9-inch size preferred |
| Heavy Cream 🥛 | ¼ cup | Optional for topping |
Sweet potatoes are the star here—orange-fleshed varieties work best. Trader Joe's and Whole Foods carry the best ones, but any grocery store will have them. Look for firm, heavy potatoes with no soft spots. Boil them until fork-tender, then mash them smooth—no lumps! The sour cream is non-negotiable for that signature velvety texture. Full-fat works best—don't skimp here. If you're feeling fancy, warm the sour cream slightly before mixing it in to blend flavors better.
No brown sugar? Substitute with white sugar plus 1 tsp molasses for depth. Freshly grated nutmeg makes all the difference—pre-ground loses punch fast. If you're missing ginger, cinnamon + cardamom can mimic that warmth. The pie crust can be store-bought (I love Pepperidge Farm for convenience), but homemade is worth it if you've got time. For extra flair, brush the crust with melted butter before baking. And if you're feeling bold, add a splash of bourbon to the filling—trust me, it elevates everything.
This pie tastes even better the next day, so bake it ahead if you can. Store leftovers in the fridge for up to 4 days, covered tightly. For serving, I like to warm slices for 10 seconds in the microwave—creamy perfection. Freezes beautifully too: wrap the whole pie in foil and freeze for up to 3 months. Just thaw overnight in the fridge before slicing. The crust stays crispy if you reheat it covered with foil, then uncover for the last minute.

Step-by-step instructions for sweet potato pie with sour cream
Let's create a velvety sweet potato filling that's rich, spiced, and perfectly balanced with a buttery crust.
Prepare the Sweet Potato Filling
Start by boiling the 2 lbs sweet potatoes in their skins until fork-tender, about 20-25 minutes. Drain and let them cool slightly before peeling. While still warm, scoop out the flesh and place it in a large mixing bowl.
Mash the sweet potatoes until completely smooth—no lumps should remain. This ensures your pie filling will be silky and creamy. I like to use a potato masher or fork for this step, but a food processor works too. The texture should be like thick pudding at this stage.
Mix the Spiced Custard Base
To the mashed sweet potatoes, add the 1 cup light brown sugar, 0.5 cup granulated sugar, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 1 tsp ground ginger, and 0.5 tsp salt. Stir well to distribute the spices evenly throughout the mixture.
Next, whisk in the 2 whole large eggs and 1 tbsp vanilla extract until fully combined. The mixture should look like a thick, spiced custard. Here's the thing—don't worry if it looks a bit curdled at first; the eggs will fully incorporate as you add the remaining ingredients.
Incorporate the Sour Cream and Thickeners
Add the 1 cup sour cream, 0.5 cup melted unsalted butter, and 0.25 cup all-purpose flour to the sweet potato mixture. Stir until completely smooth and thickened. The flour acts as a natural thickener, giving your pie that perfect custard-like texture.
Taste the mixture and adjust the sweetness or spice level if needed. I usually add a pinch more cinnamon or a bit more sugar at this stage to ensure it's just right. The filling should be thick but still pourable—like a rich, spiced pudding.
Assemble and Bake the Pie
Preheat your oven to 375°F. Roll out the 1 whole unbaked pie crust and fit it into a 9-inch pie dish, pressing gently to ensure it covers the bottom and sides evenly. Trim any excess dough from the edges.
Pour the sweet potato filling into the prepared crust, spreading it evenly. For that extra creamy touch, you can drizzle the 0.25 cup heavy cream over the top before baking. Bake for 45-50 minutes or until the filling is set and the crust is golden brown.
Cool and Serve
Remove the pie from the oven and let it cool on a wire rack for at least 2 hours. This cooling time is crucial—it allows the filling to fully set and the flavors to meld together. The pie should be firm to the touch but still warm inside.
Slice and serve with a dollop of whipped cream or a scoop of vanilla ice cream. Each bite should deliver that perfect balance of creamy sweet potato, warm spices, and buttery crust. Trust me, the wait is worth it!
Pro Tips For Making Sweet Potato Pie Recipe With Sour Cream
- Boil Potatoes Until Fork-Tender: I learned this the hard way—undercooked sweet potatoes turn your pie filling into a gloopy mess. Boil them until they’re so soft a fork slides in like butter. That’s the only way the texture stays velvety after baking, not grainy or watery.
- Whisk Sour Cream Last: Add the sour cream to the warm (not hot) filling after mixing everything else. Stirring it in too early can curdle it, and nothing ruins a pie faster than lumpy filling. Let the base cool slightly first—just enough to hold a finger in it without burning.
- Skip the Overmixing: Once you fold in the eggs, give the filling one gentle turn with a spatula. Overmixing incorporates too much air, and that’s how you end up with a dense, cakey pie instead of a light, custardy one. Rough is fine—smooth is the enemy here.
- Bake at 325°F, Not Higher: Sweet potato pies need time to set properly, and cranking the oven to 350°F just risks a cracked top or undercooked center. 325°F is the sweet spot—let it bake until the edges are set but the middle still jiggles like Jell-O. (Yes, even if you’re impatient like me.)
Storing and reheating this dish
Refrigerator Magic
This pie tastes even better the next day, so I always bake mine a day ahead. Store leftovers in an airtight container at 40°F or below for up to 4 days—the flavors deepen as the spices meld.
I like to slice it into individual portions before storing, so each serving stays perfectly creamy. For reheating, microwave slices for 10-15 seconds on 50% power to warm gently without drying out. 💫
Freezer-Friendly Secrets
Freezing whole pies is a game-changer for holiday prep. Wrap the 9-inch pie tightly in heavy-duty foil and place it in a freezer bag to prevent freezer burn. It keeps beautifully for up to 3 months—just thaw overnight in the fridge before serving.
Pro tip: Brush the crust with melted butter before freezing for extra crispiness when reheated. 🥧
Crust Perfection
The crust stays crispy if you reheat it properly. After thawing, cover the pie with foil and warm in a 350°F oven for 15 minutes. Then remove the foil and bake 5 more minutes to restore that golden crunch.
For microwave reheats, cover slices with a damp paper towel and heat for 20 seconds—this prevents the crust from getting rubbery. 🌟
Make-Ahead Mastery
Prep the filling ahead of time and store it in the fridge for up to 24 hours before baking—this saves you last-minute stress. I often make the pie crust the day before too, then assemble and bake fresh.
The key is keeping all components chilled until ready to use. This pie is perfect for Thanksgiving prep—just bake it while you're busy with other dishes! ⏰
Portion Control
Individual slices reheat best in the microwave. Place one slice on a microwave-safe plate, cover with a damp paper towel, and heat for 15-20 seconds.
For extra creaminess, add a splash of heavy cream or milk before reheating. The sour cream filling stays luscious when reheated this way—no soggy crust here! 🥛
Holiday Prep Hack
If you're baking for a crowd, assemble the pie 2 days ahead and refrigerate. Bring it to room temperature before baking (about 1 hour), then bake as directed. This ensures even cooking and prevents cracks.
I've used this trick for Christmas gatherings—everyone leaves with seconds! The pie actually improves overnight, so don't hesitate to bake extra. 🎄

Frequently asked questions
Why does this recipe use sour cream instead of milk or cream?
The sour cream creates that signature velvety texture while keeping the pie rich and moist—not dense like traditional recipes. It also adds a subtle tang that balances the sweetness perfectly. For a lighter version, you could substitute with Greek yogurt, but the richness of sour cream is hard to beat!
Can I make this pie ahead of time?
This pie actually tastes better the next day. Bake it 24 hours ahead, then store it at room temperature in an airtight container. For longer storage, freeze it for up to 3 months. Just thaw overnight in the fridge before serving. The flavors deepen as the spices meld!
What's the best way to reheat individual slices?
Microwave for 15-20 seconds on 50% power, covered with a damp paper towel. For oven reheating, cover the slice with foil and warm at 350°F for 10 minutes. The crust stays crispy if you reheat it properly—no soggy bottoms here!
Can I substitute sweet potatoes with regular potatoes?
No—sweet potatoes are essential for that natural sweetness and creamy texture. Regular potatoes would make the pie taste starchy and dry. If you can't find sweet potatoes, try canned pumpkin puree (about 1.5 cups) as a substitute, but the flavor will be slightly different.
How do I know when the pie is fully baked?
The filling should be set but still slightly jiggly in the center (like gelatin). The crust should be golden brown, and the edges should pull away from the pie dish slightly. If unsure, insert a knife near the center—it should come out clean or with just a few moist crumbs.
