In a large mixing bowl, beat butter and sugar until creamy. Add flour, salt, and eggs, beating well. Mix in buttermilk, lemon juice, and vanilla until blended.
Pour the prepared filling into a 9" pastry crust or homemade pie crust. Place the pie pan on a cookie sheet to catch any drips during baking.
Using a deep dish pie pan can help prevent overflow as the filling puffs up during baking.
Bake at 350°F for approximately 55 minutes, or until the edges are set and the top is golden brown. Adjust oven rack for desired browning.
Once baked to your preference, remove the pie from the oven and place it on a cooling rack. Let it cool for about 30 minutes.
After cooling, cover the pie and place it in the refrigerator to chill for 2-3 hours. This allows the pie to set up further as it cools.
Enjoy the pie cold or at room temperature. Some prefer it slightly warm for a comforting treat.
Add a dollop of whipped cream, a sprinkle of powdered sugar, or a drizzle of caramel sauce for extra indulgence.
Slice the buttermilk pie into portions and serve to family and friends for a delightful dessert experience.
Store any leftover pie in the refrigerator in an airtight container to maintain freshness.
Experiment with different crusts or add a hint of nutmeg or cinnamon to the filling for added flavor.
