Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 9x5-inch loaf pan with cooking spray.
Press brown sugar into the bottom of the prepared loaf pan; spread ketchup over sugar.
Mix ground beef, milk, eggs, salt, ground pepper, onion, ginger, bread crumbs, and parsley together thoroughly in a mixing bowl. Shape into a loaf and place into the pan on top of ketchup.
Bake in the preheated oven until no longer pink in the center, about 1 hour. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).
