Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
Prepare the Crust: Roll out the pie crust and press it into a 13x18-inch rimmed baking sheet. Trim any excess crust hanging over the edges.
Mix the Filling: In a large bowl, whisk together the sugar, corn syrup, melted butter, eggs, vanilla extract, and salt until it’s well combined.
Add the Pecans: Fold in the pecan halves gently, making sure they’re evenly dispersed throughout the mixture.
Pour and Bake: Pour the filling into the prepared crust and spread it evenly. Bake for about 30-35 minutes, or until the filling is set and the top is golden brown.
Cool and Slice: Let the pie cool for at least 30 minutes before slicing into squares. Serve warm or at room temperature!
