How Do You Make a Classic Southern Sweet Potato Pie?
Short answer: Bake whole sweet potatoes until tender, blend them into a smooth puree, mix with eggs, evaporated milk, butter, sugar, and warm spices, pour into a pie crust, and bake at 350°F until set.
This sweet potato pie delivers a creamy, spiced filling inside a flaky crust. It’s a traditional Southern dessert often served at Thanksgiving and holiday gatherings, but it’s simple enough to make year-round.
What Is Sweet Potato Pie?
Sweet potato pie is a baked dessert made from mashed sweet potatoes, eggs, sugar, butter, milk, and warm spices like cinnamon and nutmeg.
The texture is smooth and custard-like—similar to pumpkin pie—but slightly denser and naturally sweeter.
Ingredients (Exact Measurements)
- 3 medium sweet potatoes (about 2–2½ cups mashed)
- ½ cup evaporated milk
- 2 large eggs
- 1 teaspoon vanilla extract
- ½ cup brown sugar
- ½ cup granulated sugar
- 1 teaspoon ground cinnamon
- ½ teaspoon ground nutmeg
- ½ cup (1 stick) unsalted butter, melted
- 1 tablespoon all-purpose flour (for dusting pan)
- 1 unbaked 9-inch pie crust (store-bought or homemade)
Why These Ingredients Matter
- Evaporated milk creates a rich, creamy texture without making the filling watery.
- Eggs help the filling set like a custard.
- Butter adds depth and silkiness.
- Brown sugar enhances caramel notes.
- Cinnamon and nutmeg provide classic fall flavor.
Step-by-Step Instructions
1. Bake the Sweet Potatoes
Direct answer: Bake at 400°F for about 60 minutes until fork-tender.
- Wash and dry sweet potatoes.
- Pierce each several times with a knife.
- Place on a baking sheet.
- Bake until soft when pierced.
- Let cool, then peel.
Baking instead of boiling concentrates the natural sugars and improves flavor.
2. Make the Sweet Potato Puree
Direct answer: Blend peeled sweet potatoes until completely smooth.
- Add potatoes to a food processor or mash thoroughly by hand.
- Blend until velvety with no lumps.
You should have about 2–2½ cups of puree.
3. Prepare the Filling
In a large mixing bowl, combine:
- Sweet potato puree
- Evaporated milk
- Eggs
- Vanilla
- Brown sugar
- Granulated sugar
- Cinnamon
- Nutmeg
- Melted butter
Whisk until smooth and fully incorporated. The mixture should be creamy and pourable.
4. Prepare the Pie Crust
- Preheat oven to 350°F.
- Lightly dust the pie dish with flour to prevent sticking.
- Place the crust into the 9-inch pie dish.
- Use a fork to prick the bottom gently (this helps prevent air bubbles).
Optional: Chill crust for 10 minutes before filling to help maintain structure.
5. Assemble and Bake
Direct answer: Bake at 350°F for 50–60 minutes.
- Pour filling evenly into the crust.
- Bake until the center is mostly set.
- A toothpick inserted near the center should come out mostly clean.
The center may jiggle slightly—that’s normal. It will finish setting as it cools.
If crust edges brown too quickly, cover them loosely with foil.
6. Cool Before Serving
Let the pie cool completely at room temperature for at least 2 hours.
Cooling allows the custard filling to firm up and makes slicing easier.
How to Tell When Sweet Potato Pie Is Done
The pie is ready when:
- Edges are set
- The center jiggles slightly, but isn’t liquid
- Internal temperature reaches about 175–180°F
Avoid overbaking, which can cause cracks.

- Bake, don’t boil, to avoid excess moisture.
- Bring eggs to room temperature for smoother blending.
- Strain filling through a sieve if you want an ultra-smooth texture.
