Preheat your oven to 350°F (175°C). This step is crucial as it prepares the oven for perfect baking, ensuring your pie crust gets that lovely golden color.
In a mixing bowl, combine corn syrup, eggs, sugar, butter, and vanilla. Use a spoon to mix them well. You want to ensure that the ingredients are thoroughly combined for a smooth filling.
Once mixed, gently fold in the pecans. Make sure they are evenly distributed throughout the mixture, so every bite of your pie has that delightful nutty crunch.
Pour the filling into the prepared pie crust. Take your time with this step to avoid spills, and ensure it's evenly filled to prevent any overflow during baking.
Place the pie on the center rack of the oven. Bake for 60 to 70 minutes. You’ll know it’s done when you see the filling is set, and the crust has turned a golden brown color. Keep an eye on it to avoid overbaking.
Once baked, remove the pie from the oven and let it cool for 2 hours on a wire rack. This step is important, as it allows the filling to firm up, making it easier to slice.
