Preheat oven to 190°C and line a baking sheet with parchment or grease a loaf pan.
In a large bowl, gently mix ground chicken, Parmesan, panko, eggs, minced garlic, garlic powder, onion powder, basil, parsley, salt, pepper, and milk until just combined.
Shape the mixture into a loaf, place on the prepared pan, and bake 40–45 minutes until golden and the internal temperature reaches 74°C.
Melt butter in a small saucepan over medium heat, sauté minced garlic 1–2 minutes, then stir in Parmesan and parsley until slightly thickened; season with a pinch of salt.
Brush the baked meatloaf with the glaze and return to the oven 5–7 minutes until glossy and lightly golden.
Let rest 5 minutes before slicing, garnish with parsley, and serve warm with sides of choice.
