Ingredients You’ll Need

2 medium sweet potatoes, cooked and mashed (about 1½ cups) – Roasted or boiled until fork-tender.
1 cup buttermilk – Adds tang and helps create that velvety texture.

¾ cup brown sugar, packed – For a deep, molasses-like sweetness.
¼ cup granulated sugar – Balances the brown sugar.
½ cup unsalted butter, melted – Adds richness and helps with a smooth filling.
3 large eggs – Binds everything together.
1 teaspoon vanilla extract – Adds warmth and depth.
1 teaspoon ground cinnamon – For that classic sweet potato pie flavor.

½ teaspoon ground nutmeg – Adds a subtle, nutty spice.
¼ teaspoon salt – Enhances all the other flavors.

Step-by-Step Instructions

Preheat your oven to 350°F (175°C).
- Make sure the oven rack is positioned in the center for even baking.

Prepare the crust: Fit the pre-made pie crust into a 9-inch pie pan.
- Gently press the crust into the bottom and sides of the pan to eliminate any air bubbles.
- If you’re feeling fancy, crimp the edges using your fingers or a fork to add a decorative touch.
- Place the pie pan on a baking sheet for easier transfer and to catch any possible drips.
Mix the filling: In a large mixing bowl, add the mashed sweet potatoes, buttermilk, brown sugar, granulated sugar, melted butter, eggs, vanilla extract, cinnamon, nutmeg, and salt.
- Start by lightly beating the eggs before adding them to the mixture for a smoother blend.
- Use a whisk, hand mixer, or stand mixer on low to medium speed to blend the ingredients until the mixture is smooth and uniform.
- The batter should be creamy and pourable but not too thin.
- Don’t worry if it seems slightly loose—it will firm up perfectly as it bakes.

Pour into crust: Slowly pour the sweet potato filling into the prepared pie crust.
- Use a spatula or the back of a spoon to spread the filling evenly, smoothing out the top.
- Tap the pie pan gently on the counter to release any trapped air bubbles.

Bake: Carefully place the pie (still on the baking sheet) in the preheated oven.
- Bake for 55 to 60 minutes. Begin checking at the 50-minute mark.
- The pie is done when the center is just set (a slight jiggle is okay) and a knife inserted near the center comes out clean.
- If the crust edges begin to brown too quickly, cover them with foil or a pie crust shield halfway through the baking time.
Cool: Remove the pie from the oven and transfer it to a wire rack.
- Let it cool completely at room temperature, which may take 2 to 3 hours.
- This resting period allows the filling to set fully and the flavors to meld.
- Once cooled, refrigerate if not serving right away for best slicing and storage.

Serving and Storage Tips

Serve chilled or at room temperature. It pairs wonderfully with a dollop of whipped cream or a scoop of vanilla ice cream.

Freezer-friendly: Wrap tightly in foil and freeze for up to 2 months. Thaw overnight in the fridge.
