Preheat your oven to 350°F (175°C).

Line your baking sheet with parchment paper.

In a mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.

Beat in the eggs one at a time, followed by the vanilla extract.

In a separate bowl, whisk together the flour, baking soda, and salt.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Gently fold in the chopped pistachios.

Drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake for about 12 minutes or until the edges are lightly golden.
