Melt butter in a small saucepan over medium heat. Reduce to low and cook until butter starts to turn light brown. Set aside in the refrigerator and chill until solid, about 1 hour.

Beat together butter and sugars until light and fluffy, about 3 minutes. Add vanilla and egg and mix until incorporated.

Add flour, salt, and baking soda to the wet ingredients and mix well (do not overmix). Stir in chocolate chips and mix until just combined. Refrigerate the cookie dough for at least 30 minutes.

To bake, preheat oven to 350F. Drop cookie dough (about 2 tablespoons) onto baking sheets lined with parchment paper, and bake for 12-15 minutes, or until golden brown around the edges.

Remove from oven and let cookies cool for 5 minutes on baking sheets before transferring to a cooling rack to cool completely.
