Set the oven to 350°F. Then grease a 9-inch pie dish with baking spray.
If using unbaked pie dough, unroll 1 (9-inch) unbaked or frozen pie crust and place it into the center of the pie dish.
Shape the dough into the pie dish gently with your fingertips.
Pour the roughly chopped 2½ cups pecans into the pie dish on top of the crust.
In a separate mixing bowl, combine 3 large eggs, 1 cup light corn syrup, ¾ cup light brown sugar, 3 tablespoons butter, 1 teaspoon vanilla extract, 1 teaspoon ground cinnamon, and ½ teaspoon sea salt using a mixing spoon or baking spatula.
Pour the mixture into the pie dish over the top of the pecans. Smooth the top of the filling with a baking spatula to level.
Bake the pecan pie for 60 to 65 minutes in the preheated oven.
Once baked, allow the pie to cool on the countertop for 3 hours before cutting and serving.
