01 - Preheat oven to 375°F. Line a 9x5-inch loaf pan with parchment paper or lightly grease with cooking spray.
02 - In a large bowl, combine ground chicken, minced garlic, chopped onion, parsley, Parmesan cheese, milk, egg, breadcrumbs, salt, pepper, and Italian herbs. Mix gently until just incorporated—avoid overmixing to prevent dense texture.
03 - Transfer mixture into the prepared loaf pan, pressing firmly to eliminate air pockets and create an even surface.
04 - In a small bowl, combine 0.5 cup grated Parmesan cheese with melted butter. Mix thoroughly to form a crumbly mixture.
05 - Sprinkle Parmesan-butter mixture evenly over the meatloaf surface. Bake for 45 to 50 minutes until internal temperature reaches 165°F and topping is golden brown.
06 - Remove from oven and let meatloaf rest for 10 minutes in the pan. This allows juices to redistribute for easier slicing. Garnish with additional fresh parsley if desired.
