If you're planning to freeze these meatballs, we actually recommend sticking to dried herbs here (dried basil, thyme, rosemary, and oregano are all great). Fresh herbs will lose a lot of their flavor in the freezer, so they won't make as big of a difference here as dried herbs will. But we love adding a sprinkle of fresh basil or fresh parsley to the finished dish when it's time to serve these meatballs!
