Preheat oven to 375°F (190°C) and line a loaf pan with parchment paper.
In a large mixing bowl, combine the panko breadcrumbs and milk, letting them sit for 5 minutes to create a panade.
Add the ground chicken, parmesan cheese, beaten egg, minced garlic, parsley, oregano, salt, and pepper to the bowl.
Gently mix the ingredients by hand until just combined, being careful not to overwork the meat.
Transfer the mixture into the prepared loaf pan and smooth the top with a spatula.
Bake for 45 to 50 minutes, or until the internal temperature reaches 165°F (74°C).
Allow the meatloaf to rest for 10 minutes before slicing to ensure juiciness.
