Preheat your oven to 350°F (175°C) and lightly grease a loaf pan.
In a large bowl, combine ground beef, breadcrumbs, onion, garlic, milk, eggs, ketchup, Worcestershire sauce, salt, pepper, and thyme. Mix until evenly combined.
Transfer the mixture to the prepared loaf pan, pressing down gently to shape it.
Spread an additional layer of ketchup over the top for a glaze.
Bake in the preheated oven for 1 hour, or until the internal temperature reaches 160°F (70°C).
Let the meatloaf rest for 10 minutes before slicing. Serve warm and enjoy!
