You can make this creamy, tangy, and sweet buttermilk pie using simple pantry staples. This old-fashioned dessert delivers a silky custard filling and a flaky crust, proving that great baking does not require complex techniques.

Ingredients

Scale
  • 1 (9-inch) unbaked pie crust
  • 1 1/2 cups granulated sugar
  • 3 large eggs
  • 1 cup buttermilk
  • 1/4 cup all-purpose flour
  • 1/4 cup unsalted butter, melted
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon ground nutmeg (optional, for topping)

Instructions

  1. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Place your unbaked pie crust into a 9-inch pie plate.
  2. In a medium bowl, whisk together the granulated sugar and the flour until they are fully combined.
  3. Add the eggs to the sugar and flour mixture. Whisk until the mixture is smooth.
  4. Gradually whisk in the buttermilk, melted butter, and vanilla extract until the filling is uniform. Do not overmix.
  5. Pour the buttermilk filling into the prepared pie crust.
  6. Bake for 40 to 50 minutes. The center should be mostly set but still have a slight jiggle when gently shaken. The top should be golden brown.
  7. If the crust edges start to brown too quickly, cover them loosely with aluminum foil halfway through baking.
  8. Remove the pie from the oven. If desired, lightly dust the top with ground nutmeg immediately after removing it.
  9. Let the pie cool completely on a wire rack for at least 2 hours before slicing. The custard will continue to set as it cools.

Notes

  • For a truly flaky crust, keep your butter cold when preparing the pastry.
  • If you do not have buttermilk, you can make a substitute by adding 1 tablespoon of white vinegar or lemon juice to 1 cup of whole milk and letting it sit for 5 minutes.
  • This pie is excellent served at room temperature or slightly chilled.
