Preheat the oven to 350?F and spray a 9?5?2-inch loaf pan with nonstick cooking spray.

In a large mixing bowl, combine ground chicken, Italian breadcrumbs, grated Parmesan cheese, minced yellow onion, minced garlic, egg, whole milk, 2 tablespoons chopped parsley, salt, and black pepper. Mix until well combined.

Form the meat mixture into a loaf, and place it into the prepared loaf pan. Top with shredded parmesan cheese and the remaining 1 tablespoon of chopped parsley.

Bake in the preheated oven for 1 hour. Broil for the last 2 minutes to get the top golden brown. Watch it closely!
