Preheat your oven to 350°F (175°C). Lightly grease a loaf pan or line it with parchment paper.
In a large bowl, combine ground beef, breadcrumbs, eggs, milk, chopped onion, minced garlic, ¼ cup ketchup, Worcestershire sauce, salt, and black pepper. Mix until just combined.
Transfer the meat mixture into the prepared loaf pan and shape it into a loaf.
In a small bowl, mix ½ cup ketchup with brown sugar. Spread the glaze evenly over the top of the meatloaf.
Bake in the preheated oven for 1 hour, or until the meatloaf is cooked through and the internal temperature reaches 160°F (71°C).
Let the meatloaf rest for 10 minutes before slicing and serving.
