For years I hosted a legendary 48-hour pig roast, the kind of party where the whole pig, the location, and the entertainment were my contribution, while the guests brought sides and desserts. One year, someone showed up with a Buttermilk Pie from the famous Buttermilk Pie Company. I took one bite and was hooked. That pie set me on a journey to recreate the same silky, nostalgic flavor in my own kitchen.
This version stays true to that inspiration. The pie features a golden, flaky crust filled with a sweet custard that bakes until it’s creamy, smooth, and just firm enough to hold a delicate jiggle in the center. It is simple, comforting, and Southern to the core. Served chilled the next day, the flavors settle into perfection.
A Little History
Buttermilk pie is a staple in Southern kitchens, born from the resourcefulness of using simple pantry ingredients: buttermilk, eggs, sugar, and flour. Families across Texas and the South baked it for holidays, church gatherings, and BBQ spreads. This recipe takes inspiration from the Buttermilk Pie Company’s iconic version and brings it home for anyone to enjoy.

Description of the Finished Dish

This Southern custard pie is smooth, sweet, and creamy with a subtle tang from buttermilk and lemon. The top bakes golden and lightly caramelized, while the inside stays rich and silky. It is a dessert that balances comfort and elegance, perfect on its own or with a dollop of whipped cream.

What to Look For

  • Light golden top: Custard should have a slightly caramelized surface.
  • Gentle jiggle in the center: Ensures a creamy, smooth custard without overbaking.
  • Silky filling: Texture should be custard-like, not grainy.

Pro Tips

  • Let the pie chill overnight for the best flavor and sliceable texture.
  • Place foil over the crust edges if they brown too quickly.
  • Fresh lemon juice balances the sweetness and enhances the tang of buttermilk.
  • Serve chilled slices with fresh berries for a bright contrast.

Variations

  • Coconut Custard Pie: Add ½ cup shredded coconut to the filling.
  • Citrus Twist: Replace lemon juice with orange zest for a softer flavor.
  • Bourbon Custard Pie: Add 1 tablespoon bourbon for depth and smokiness.
  • Mini Pies: Use small tart pans for individual servings at BBQ events.
