Bake this traditional Southern Buttermilk Pie for a comforting, tangy, and sweet dessert. This recipe delivers a creamy custard filling in a flaky crust, just like Grandma used to make.

Ingredients

Scale
  • 1 (9-inch) unbaked pie crust (all-butter recommended)
  • 1 1/2 cups granulated sugar
  • 3 tablespoons all-purpose flour
  • 1/4 teaspoon salt
  • 1 cup buttermilk
  • 1/2 cup (1 stick) unsalted butter, melted
  • 2 large eggs, lightly beaten
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat your oven to 350°F (175°C). Place your unbaked pie crust into a 9-inch pie plate.
  2. In a medium bowl, whisk together the sugar, flour, and salt until combined.
  3. In a separate bowl, whisk together the buttermilk, melted butter, eggs, and vanilla extract until smooth.
  4. Slowly pour the wet ingredients into the dry ingredients while whisking constantly until the filling is uniform. Do not overmix.
  5. Pour the buttermilk filling into the unbaked pie crust.
  6. Bake for 45 to 55 minutes. The center should be mostly set but still have a slight wobble. The top should be golden brown.
  7. Cool the pie completely on a wire rack for at least 3 hours before slicing. This allows the custard to fully set.
  8. Serve slightly warm or at room temperature, often with a dollop of fresh whipped cream.

Notes

  • For a truly old-fashioned crust, use a lard or shortening crust instead of all-butter.
  • If your pie top browns too quickly, loosely cover the edges with aluminum foil halfway through baking.
  • This pie tastes best when served the day it is made, but leftovers keep well covered in the refrigerator for up to 3 days.
