Preheat oven to 350 degrees and line two cookie sheets with parchment paper.
Using a medium bowl, whisk the flour, baking soda, kosher salt.
Using a standing mixer, beat the butter, sugar, lemon zest, eggs, and vanilla until combined, creamy and smooth.
Beat in the ricotta cheese until combined.
Gradually beat in the dry ingredients until combined and a soft dough forms.
Using a small cookie scoop, drop the cookie dough onto the cookie sheets about 2 inches apart.
Once trays have a minimum of 12 cookies, place in the oven and bake for 10-12 minutes or until lightly brown.
Remove and place on the counter to cool.
Once cookies are cooled, place onto a wire rack.
