Preheat your oven to 350°F and line a baking sheet with parchment paper.
In a large mixing bowl, cream together the softened butter and 1/2 cup powdered sugar until light and fluffy.
Add the vanilla and almond extracts, mixing until well combined.
Gradually add the flour and salt, mixing until just combined.
Fold in the finely chopped pistachios.
Using a tablespoon, scoop out the dough and roll it into small balls, placing them on the prepared baking sheet about 2 inches apart.
Bake for 15-18 minutes, or until the bottoms are lightly golden.
Remove from the oven and let cool for a few minutes before transferring to a wire rack.
Once cooled, dust the cookies with additional powdered sugar.
