Preheat your oven to 350°F (175°C) and line your baking sheets with parchment paper.
In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar using an electric mixer until light and fluffy.
Beat in the eggs one at a time, followed by the vanilla extract, mixing well after each addition.
In a separate bowl, combine the flour, baking soda, and salt. Gradually add this dry mixture to the wet mixture, mixing until just combined.
Fold in the chopped pecans with a spatula or wooden spoon.
Using a cookie scoop or spoon, drop rounded tablespoons of the dough onto the prepared baking sheets, leaving space between each cookie.
Bake in the preheated oven for 10 to 12 minutes, or until the edges are lightly golden.
Remove from the oven and let the cookies cool on the baking sheets for a few minutes before transferring them to a cooling rack to cool completely.
