Ingredients for simply sweet potato pie
Six ingredients for the filling and six for the crust—simple, classic, and foolproof.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 ½ lb | Peeled, cooked until tender |
| All-Purpose Flour 🌾 | 2 ½ cups | For pie crust |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for crust |
| Granulated Sugar 🍚 | 1 ½ cups | Light brown preferred |
| Evaporated Milk 🥛 | 1 cup | Full-fat for creaminess |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Ground Cinnamon 🌿 | 2 tsp | Freshly ground preferred |

The sweet potatoes are the heart of this pie, so pick firm, vibrant orange ones—the deeper the color, the sweeter the flavor. Trader Joe's and Whole Foodscold butter is non-negotiable—it creates those flaky layers. Use a food processor for the dough, but don't overmix. The filling's spices need to be freshly ground—pre-ground spices lose their punch fast.
No evaporated milk? Full-fat coconut milk works perfectly—just reduce the sugar slightly. Short on vanilla? Vanilla bean paste adds extra depth, or a splash of bourbon for warmth. The crust can be made ahead and chilled for up to 48 hours, which actually improves the texture. For a gluten-free version, swap the flour for a 1:1 gluten-free blend. The sweet potatoes can be roasted in batches if you're feeding a crowd—just keep them warm until ready to mash.
The filling keeps in the fridge for 5 days—great for making ahead. The crust can be pre-baked and frozen for up to 3 months. Once assembled, this pie holds together beautifully for 24 hours before baking, so it's perfect for holiday prep. Slice and serve at room temperature—waiting just 10 minutes lets the filling set up nicely. Store leftovers in an airtight container for up to 4 days, though it rarely lasts that long.

Step-by-step instructions for simply sweet potato pie
Here's the method for a silky-smooth filling and perfect crust every time.
Prepare the Sweet Potato Filling
Preheat your oven to 350°F. Peel and slice the 2.5 lb sweet potatoes into ½-inch thick rounds. Place them on a baking sheet and bake for 45-50 minutes until completely tender and easily pierced with a fork. Let them cool slightly before handling.
Once cool enough to handle, transfer the sweet potatoes to a food processor or large mixing bowl. Mash them until completely smooth, scraping down the sides as needed. The texture should be completely free of lumps—this ensures a velvety pie filling. I like to use the food processor for this step as it gives me that ultra-smooth consistency.
Mix the Filling Ingredients
In a large mixing bowl, combine the mashed sweet potatoes with 1.5 cups granulated sugar, 1 cup evaporated milk, 2 whole large eggs, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 1 tsp ground ginger, and 0.5 tsp salt. Mix thoroughly until all ingredients are evenly distributed and the mixture is smooth.
Next, stir in the 1 tbsp vanilla extract. This step is crucial for developing the pie's signature warm, aromatic flavor. The vanilla enhances the spices and adds depth to the sweet potato's natural sweetness. Taste the mixture at this point—it should be sweet, spiced, and balanced. If you want to adjust the flavor, this is your last chance before baking.
Prepare the Pie Crust
In a separate bowl, combine the 2.5 cups all-purpose flour and 0.5 tsp salt. Cut in the 1 cup cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. Gradually add the 0.5 cup ice water, one tablespoon at a time, mixing just until the dough comes together.
Turn the dough out onto a lightly floured surface and knead it gently for 30 seconds until it forms a smooth ball. Divide the dough in half and roll out each half to fit a 9-inch pie dish, pressing the dough into the bottom and up the sides. Trim any excess dough and crimp the edges with a fork. Chill the crust in the refrigerator for 30 minutes while you prepare the filling.
Assemble and Bake the Pie
Pour the sweet potato filling into the chilled pie crust, spreading it evenly. Preheat your oven to 375°F. Place the pie on a baking sheet lined with parchment paper to catch any potential drips. Bake for 45-50 minutes until the filling is set and the crust is golden brown.
To check doneness, gently shake the pie—if the filling doesn't jiggle, it's ready. The center should be just set, not completely firm. If the crust starts to brown too quickly, tent it with aluminum foil to prevent over-browning. Let the pie cool completely on a wire rack before slicing—this allows the filling to set properly and makes for cleaner slices.
Pro Tips For Making Simply Sweet Potato Pie
- Boil Until Fork-Tender: Sweet potatoes straight from the oven? Skip it. Boil them whole in salted water until they collapse under a fork—about 45 minutes for medium-sized tubers. I learned this the hard way: roasted potatoes turn to mush when mashed, while boiled ones stay creamy and uniform, which is non-negotiable for a smooth pie filling.
- Whisk the Butter First: Melt the butter and sugar together before adding the flour. This creates a silky base that blends better with the sweet potato purée, preventing lumps in the filling. I used to toss the flour in cold and wondered why my pie tasted more like a dense pudding than a custard.
- Watch the Evaporated Milk: Don’t drown the mixture—use just enough evaporated milk to loosen the filling to a thick pudding consistency. Too much and your pie will weep; too little and it’ll be dry. Aim for about ½ cup for a standard 9-inch pie, then taste-test before baking.
- Prevent a Soggy Crust: Chill the pie crust for at least 30 minutes before filling, then blind-bake it for 10 minutes at 375°F (200°C). This ensures it holds its shape and doesn’t turn to mush when the custard steams. I skipped this once and ended up with a pie that looked like a sad, soggy pancake.
Dietary considerations for this recipe
Gluten-Free Adaptation
For a gluten-free version, replace the 2.5 cups all-purpose flour in the crust with a 1:1 gluten-free flour blend like King Arthur Measure for Measure or Bob's Red Mill 1-to-1. These blends mimic the texture of wheat flour perfectly.
Chill the dough for an extra 15 minutes before rolling to prevent cracking. The filling remains unchanged, so you still get that creamy, spiced goodness without compromising flavor. 🌾
Dairy-Free Options
Skip the 1 cup evaporated milk and 1 cup butter by using 1 cup full-fat coconut milk (canned, not carton) for creaminess. Reduce the 1.5 cups sugar to 1.25 cups since coconut milk is sweeter.
For the crust, substitute 1 cup cold vegan butter (like Miyoko's) or coconut oil (solidified). The texture stays flaky, and the filling remains rich and velvety. 🥥
Vegan Sweet Potato Pie
Transform this into a vegan pie by replacing the 2 eggs with 2 tbsp ground flaxseed mixed with 6 tbsp water (let it sit for 5 minutes to thicken).
Use 1 cup coconut cream (from a can) instead of evaporated milk and 1 cup vegan butter (like Earth Balance) in the crust. The spices and sweet potatoes shine just as brightly without any animal products. 🌱
Lower-Sugar Version
Cut the 1.5 cups sugar to 1 cup and boost the natural sweetness by roasting the sweet potatoes 10 minutes longer (until caramelized). Add 1 tbsp maple syrup to the filling for depth.
The pie will still be rich but with 33% less sugar—perfect for those watching their intake while keeping that classic taste. 🍯
Nut-Free Allergy-Friendly
This recipe is naturally nut-free, but if you're concerned about cross-contamination, use a dedicated food processor for the crust and filling. Store ingredients separately until mixing, and clean surfaces thoroughly. The filling’s spices and sweet potatoes provide all the flavor without nuts—no compromises needed! ✨

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
No, sweet potatoes are essential for this recipe! Regular potatoes lack the natural sweetness and vibrant orange color that make sweet potato pie special. The moisture content and starch levels are different too, which would make the filling gummy or watery. If you absolutely must substitute, try yams—but they're not the same!
How do I prevent a soggy crust?
Prevent soggy bottoms by chilling the crust for 30 minutes before adding filling, and blind-baking it for 8-10 minutes at 375°F with pie weights or dried beans. The filling should be slightly thickened (not runny) before pouring. For extra insurance, brush the crust edges with egg wash before baking.
Can I make this pie ahead of time?
Assemble the pie (unbaked) and refrigerate for up to 24 hours before baking. For make-ahead baking, prepare the filling and crust separately, then assemble and bake when ready. The filling can be made 2 days ahead and stored in the fridge—just reheat gently before assembling.
Why is my pie filling too runny?
Overmixing the filling or using too much milk are common culprits. The filling should coat the back of a spoon but not drip. For a thicker texture, reduce the evaporated milk by ¼ cup or add 1 tbsp cornstarch mixed with 1 tbsp water to the filling. Bake at 350°F instead of 375°F for a slower set.
What's the best way to reheat slices?
Sweet potato pie is best served at room temperature, but if reheating is necessary, warm slices in a 350°F oven for 5-8 minutes covered with foil. Microwaving can make the crust soggy—never reheat this way. For serving at gatherings, keep the whole pie at room temperature for 2 hours before slicing.
