Preheat your oven to 375°F (190°C).
In a large bowl, combine ground chicken, breadcrumbs, Parmesan cheese, parsley, garlic, and egg.
Add salt, pepper, Italian seasoning, and milk. Mix until well combined.
Form the mixture into meatballs, about 1.5 inches in diameter.
Place meatballs on a lined baking sheet, spaced evenly apart.
Bake for 20-25 minutes or until golden brown and cooked through.
While baking, prepare your sauce or side dishes.
Once cooked, remove meatballs from the oven and let them rest for 5 minutes.
Serve with your favorite sauce or as desired.
Enjoy your delicious ground chicken meatballs!
