Grandma’s Sweet Potato Pecan Pie is the best of both worlds—smooth, spiced sweet potato filling with a crunchy, caramelized pecan topping.
It’s rich, cozy, and packed with deep Southern flavors that bring back memories of family gatherings and holiday tables. This pie isn’t just dessert—it’s tradition, made with love and a whole lot of flavor. In restaurant kitchens, we always make sure every layer of a dish has balance, and this pie does just that.
The buttery, flaky crust holds a perfectly spiced sweet potato layer, then gets topped with a pecan mixture that turns into a crackly, candy-like topping in the oven. It takes patience—especially waiting for it to cool—but it’s worth every minute.
This pie is made for sharing, and it’s surprisingly simple to pull together with a little planning. Swap nutmeg for allspice, add a splash of bourbon to the pecan topping, or serve it warm with a scoop of vanilla ice cream.
However you slice it, this pie is pure Southern comfort. So grab your rolling pin, and let’s make something special!
What Makes This Recipe Special?

- Layers of Texture: The creamy sweet potato filling contrasts beautifully with the crunchy pecan topping.
- Deep, Warm Spices: Cinnamon, nutmeg, and a hint of vanilla make every bite taste like fall.
- Less Syrupy Sweetness: Unlike classic pecan pie, this version is naturally sweetened with sweet potatoes, reducing the need for excess sugar.
- Perfect Make-Ahead Dessert: This pie tastes even better the next day, as the flavors meld together overnight.
