Preheat your oven to 350°F (175°C). Place your unbaked pie crust into a 9-inch pie dish and gently press it into the edges. Crimp the sides as desired and set it aside while you prepare the filling.
In a large bowl, whisk together the corn syrup, brown sugar, melted butter, eggs, vanilla extract, and salt until fully combined. Make sure the mixture is smooth but avoid overmixing, as too much air can affect the texture.
Stir the pecan halves into the filling mixture until evenly coated. Pour everything carefully into the prepared pie crust, spreading the pecans evenly so they settle nicely on top during baking.
Place the pie on a baking sheet and transfer it to the oven. Bake for 50 to 60 minutes, or until the center is set but still slightly jiggly. If the crust edges brown too quickly, cover them loosely with foil.
Remove the pie from the oven and let it cool at room temperature for at least 2 hours. The filling will continue to set as it cools, giving you clean, beautiful slices.
