In a food processor, pulse half the dill and the garlic clove until the garlic is chopped. Add the cheeses and lemon zest and pulse again for a minute or two until the mixture is almost totally smooth.
Turn the cheese mixture onto a piece of plastic wrap spritzed with cooking spray. Wrap the cheese in the plastic wrap, gently forming into a ball as you seal the plastic. Place the cheese ball in a bowl to prevent a flat edge, and chill for 2 hours up to 2 days.
When ready to serve, put the remaining dill on a plate. Roll the cheese ball in the dill until it's totally covered.
Serve as desired. Enjoy!
