In a medium bowl, combine ground chicken, grated garlic, breadcrumbs, egg, parmesan, all but 2 tablespoons of the parsley, the zest of the lemon, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Roll mixture into 1-inch round balls and place on prepared sheet pan.
Do you ever make these ahead and freeze them?
You certainly can! There are two ways you could do it. 1. Freeze them in a container with the sauce already on them. 2. Freeze the meatballs alone on a sheet tray and then transfer the frozen meatballs to a bag. Then, you can make the sauce while you bake the meatballs (either frozen or thawed) in the oven.
