Preheat Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Cream Butter and Sugars: In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. Add the egg and vanilla extract, mixing until well combined.
Combine Dry Ingredients: In another bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in Pecans: Gently fold in the chopped pecans.
Shape Cookies: Drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake: Bake for 10-12 minutes, or until the edges are lightly golden. Allow to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
