1-First, preheat your oven to 350°F (175°C) and gather your ingredients. Begin by beating 1/2 cup softened butter and 1 1/4 cups sugar in a large bowl until creamy, which creates a smooth base for the filling. Next, add 3 tablespoons all-purpose flour, 1/4 teaspoon salt, and 3 large eggs, then beat until everything is smooth and well combined.

2-Once that’s done, blend in 1 cup buttermilk, 1 tablespoon lemon juice, and 1 teaspoon vanilla extract; don’t worry if the mixture looks a bit curdled at this stage, as it will even out during baking. Pour the filling into the 9-inch pastry crust, making sure to use a deep dish if possible, and place the pie pan on a cookie sheet for even baking. Bake for 50-55 minutes, or until the top is lightly browned and the filling is mostly set.

3-After baking, let the pie cool on a rack and serve it at room temperature for the best flavor.
