Preheat oven to 400F. Prepare a sheet pan by greasing or lining it with parchment paper.
Squeeze dry zucchini of excess liquid, discard liquid. Mix all the zucchini and all other ingredients by hand or with a spoon until well combined.
Use a cookie scoop or eyeball. Two tablespoons are needed to make each meatball and place it on the cookie scoop.
Bake for 20-25 minutes or until internal temperature reaches 165F. If desired, broil for 2-3 minutes so the tops of the meatballs get crispy. Serve immediately with sauce and pasta, or eat on their own!
