Preheat your oven to 350°F (175°C).

In a large mixing bowl, combine the ground beef, grated Parmesan cheese, torn bread or breadcrumbs, chopped parsley, and the egg. Mix until well blended.

Transfer the meat mixture into a baking dish and shape it into a loaf.

In a small bowl, whisk together the ketchup and brown sugar until fully combined. Spread this mixture over the top of the shaped loaf.

Place the meatloaf in the preheated oven and bake for 45 minutes. Check with a meat thermometer for doneness (internal temperature of 160°F or 70°C).

Remove the Perfect Meatloaf from the oven and let it rest for about 10 minutes before slicing.
