Southern Buttermilk Pie
This is one of those pies that sounds unusual until you actually taste it — buttermilk on its own is tangy and thin, but baked into a custard with sugar, eggs, and a little flour, it turns into something rich, slightly caramelized on top, and genuinely addictive. It's a pantry-staples pie, the kind Southern cooks turned to when fresh fruit wasn't in season but buttermilk always was.
There's no fussy technique here — whisk, pour, bake. The whole filling comes together in one bowl with no mixer required.

Why This Recipe Works
The small amount of flour in the filling helps stabilize the custard as it bakes, giving it a sliceable set rather than a loose, jiggly texture. Buttermilk's natural acidity balances the sugar's sweetness and is what gives this pie its distinct tang — swapping in regular milk would make it noticeably flatter in flavor.

Step-by-Step
Step 1: Prepare the Crust
Fit the pie crust into a 9-inch pie dish, trimming and crimping the edges as desired. No need to pre-bake the crust for this recipe.
Step 2: Mix the Filling
Whisk the sugar and flour together in a large bowl. Whisk in the melted butter, then the eggs one at a time, followed by the buttermilk, vanilla, salt, and nutmeg until fully smooth.
Step 3: Fill and Top
Pour the filling into the prepared crust. Sprinkle a little extra nutmeg over the top for both flavor and visual finish.
Step 4: Bake
Bake at 350°F (175°C) for 45 to 50 minutes, until the top is golden brown and the center has just a slight jiggle — it will continue to set as it cools. If the crust edges brown too quickly, cover them loosely with foil.
Step 5: Cool and Slice
Cool completely at room temperature, at least 3 hours, before slicing. The custard needs this time to fully set for clean slices.
Pro Tips
- Watch for a slight jiggle: that's the correct doneness cue — a fully still center likely means it's overbaked.
- Cover the crust edges if needed: a pie shield or foil strip prevents over-browning during the long bake.
- Room-temperature eggs blend more smoothly: cold eggs can make the filling slightly lumpy going in.
- Give it the full cool time: slicing warm results in a soft, slumping filling instead of clean wedges.
Storage & Make-Ahead
Refrigerate the cooled pie, covered, for up to 4 days. Serve chilled or at room temperature — both work well. This pie freezes acceptably for up to 2 months, though the texture is best enjoyed fresh within the first few days.
Variations & Substitutions
- Lemon buttermilk pie: add 2 tablespoons of lemon juice and 1 teaspoon of lemon zest for a brighter version.
- Coconut buttermilk pie: fold in ½ cup shredded coconut for added texture.
- Spiced version: add a pinch of cinnamon alongside the nutmeg for a warmer flavor.
- Mini pies: divide the filling among mini tart shells for individual servings, reducing bake time to about 25-30 minutes.
