Preheat the oven to 350°F (175°C).

In a large bowl, cream together the unsalted butter, granulated sugar, and brown sugar until smooth.

Beat in the eggs and vanilla extract until well combined.

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

Gradually add the dry ingredients to the wet ingredients and mix until just combined.

Fold in the chopped pistachios and white chocolate chips.

Drop tablespoon-sized portions of dough onto a baking sheet lined with parchment paper.

Sprinkle extra chopped pistachios on top of the cookie dough.

Bake in the preheated oven for 10-12 minutes or until edges are lightly golden.

Allow cookies to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
