Preheat oven to 350 degrees Fahrenheit.

Sift together flour, baking soda, and salt in a bowl.

In a separate bowl, cream together softened butter, light brown sugar, and granulated sugar using an electric mixer until light and fluffy.

Beat in the eggs one at a time, then stir in the vanilla extract.

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

Fold in the white chocolate chips and chopped pistachios.

Drop rounded teaspoonfuls of dough onto an ungreased cookie sheet, spacing them about 2 inches apart.

Bake for 10-15 minutes, or until the edges are lightly golden brown.

Remove from oven and let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

Store in an airtight container at room temperature.
