In a large bowl, combine the cream cheese, ranch seasoning and Parmesan cheese. Mix until it is creamy, smooth and well combined.
Transfer it to a smaller bowl and put it in the refrigerator for about 30 minutes.
Use a spatula or clean hands to turn it out onto a platter and shape into a ball.
If desired, you can "roll" the cheeseball carefully in chopped pecans or walnuts. (I never do this because my husband isn't a fan of nuts on cheeseballs.)
Serve with yummy crackers.
Refrigerate any leftovers.
