This Buttermilk Sweet Potato Pie recipe has been in my family for generations. I learned it from my grandmother who made it every holiday season. The combination of roasted sweet potatoes and tangy buttermilk creates something truly magical. Every time I make it, the kitchen fills with the most incredible warm, spicy aroma.
The Story Behind This Recipe
I've tweaked my grandmother's recipe over the years, adjusting the spices and perfecting that silky smooth texture. The buttermilk was actually my addition—she used regular milk, but that subtle tang makes all the difference. Now my kids say it's not the holidays without this pie.
What You'll Need
- Sweet Potatoes: I always roast them myself—it makes them extra sweet and caramelized.
- Buttermilk: Full fat gives the best texture and flavor.
- Spices: Fresh grated nutmeg and cinnamon from my spice drawer.
- Pie Crust: My butter crust recipe works perfectly here.
- Eggs: Always use room temperature—they blend better.
- Sugars: A mix of white and brown creates the perfect sweetness.
Let's Start With Sweet Potatoes
Pop those sweet potatoes in the oven at 400°F. I usually do this part a day ahead when I'm not rushed. The trick is roasting them until they're super soft and caramelized. The smell alone tells you when they're ready. Once they're done, peeling is easy, and they mash like a dream.
Creating Your Crust
I've learned that a good crust can make or break your pie. Roll it out nice and thin, then gently lift it into your pan. I always crimp the edges just like my grandmother taught me. A quick pre-bake keeps it crispy even under all that creamy filling.

Making The Filling
Here's where the magic happens. Get your sweet potatoes super smooth first, then mix in melted butter, spices, and a touch of lemon juice to brighten everything up. The eggs and sugar go in next, followed by flour and that wonderful buttermilk. Take your time here—lumps are not your friend.
The Secret to Light Texture
This is my favorite trick: folding in whipped egg whites makes the filling incredibly light and airy. Just be gentle when you fold them in—you want to keep all those tiny air bubbles. My daughter loves helping with this part.
Time to Bake
The hardest part is waiting while it bakes. Keep the oven at 375°F and resist the urge to peek too often. You'll know it's done when the edges are set but the center still has a slight wobble. Think of how custard jiggles—that's what you're looking for.
The Waiting Game
Let it cool completely before you slice it. I know it's tempting, but trust me—patience makes perfect slices. Sometimes I make it the night before and let all those flavors blend together in the fridge.
My Best Tips
After years of making this pie, I've learned a few things. Room temperature ingredients are crucial. Take your time with the sweet potatoes, getting them really smooth. And always, always pre-bake that crust.

Mix It Up
Sometimes I add fresh ginger for extra warmth or orange zest for brightness. Last Thanksgiving, I sprinkled chopped pecans on top before baking—everyone loved that nutty crunch.
Make It Ahead
This pie actually gets better after a day in the fridge. All those spices and flavors have time to really come together. Just pull it out about an hour before serving.
Saving Some For Later
If you're lucky enough to have leftovers, this pie freezes beautifully. Wrap it well, and it'll keep for months. Though in my house, it rarely lasts that long.
Perfect Pairings
We love this with fresh whipped cream or a scoop of vanilla ice cream. My husband insists on having his with strong black coffee—says it's the perfect combination.
A Taste of Home
This pie has been part of our family celebrations for as long as I can remember. It's amazing how one recipe can hold so many memories. Every time I make it, I think of my grandmother in her kitchen.

Good For You Too
Sweet potatoes are packed with nutrients, so I like to think this pie is practically health food. At least that's what I tell myself when I'm having a second slice.
Perfect For Any Time
While it's traditionally a holiday pie, I make it year-round. It's just as perfect for a summer evening as it is for Thanksgiving dinner.
Playing With Crusts
Sometimes I make it with a graham cracker crust or even a gingersnap one. Each version brings something new to the table, though the classic butter crust is still my favorite.
When Company Comes
This is my go-to dessert when I want to impress guests. Something about homemade pie just makes people feel special. Plus, it looks beautiful on the table.
Why This Recipe Works
The magic of this pie is in its simplicity. Good sweet potatoes, tangy buttermilk, warm spices, and a perfect crust. It's comfort food at its finest, and I hope it becomes a tradition in your family too.
