Slow Cooker Turkey Meatballs

Spray the bottom of a slow cooker with cooking spray.

Pour 1 cup marinara sauce into the prepared slow cooker.

Combine turkey, Parmesan cheese, parsley, milk, egg, salt, and pepper in a bowl; stir to combine. Add bread crumbs and mix using your hands until well combined.

Form meat mixture into tangerine-sized meatballs. Place into the slow cooker and pour remaining marinara sauce on top.

Cover and cook until meatballs are no longer pink in the centers, about 4 hours on High, or about 8 hours on Low.
