Mix 1 cup of granulated sugar, 3 tablespoons of light brown sugar, ½ teaspoon of salt, 1 cup of light corn syrup, ¾ teaspoon of vanilla extract, ⅓ cup of melted salted butter, and 3 large eggs.
Stir in 1½ cups of pecan halves and pour into 1 unbaked pie crust. Bake for 10 minutes.
Reduce the oven to 350°F / 175°C and bake for about 50 minutes more, tenting with greased foil halfway through, until the center jiggles only slightly when gently shaken. Cool completely before slicing.
