Preheat your oven to 350°F (175°C).
In a large mixing bowl, whisk together the corn syrup, sugar, eggs, melted butter, and vanilla extract until smooth.
Place the pie crust in a 9-inch pie dish. Scatter the pecan halves evenly over the crust.Pour the filling mixture over the pecans. The pecans will float to the top as the pie bakes.
Place the pie in the preheated oven and bake for 50–60 minutes or until the filling is set but slightly jiggly in the center. Cover the edges with foil if they start to brown too quickly.
Let the pie cool completely before slicing. Serve with a dollop of whipped cream or a scoop of vanilla ice cream.
