Preheat your oven to 350°F (175°C).

Lightly grease a baking dish or loaf pan with cooking spray.

In a large mixing bowl, combine the ground beef and ground pork.

Add breadcrumbs, milk, chopped onion, minced garlic, eggs, Worcestershire sauce, salt, and pepper to the meat.

Mix the ingredients until just combined.

Transfer the mixture to your prepared baking dish and shape it into a loaf.

In a small bowl, mix ketchup and brown sugar to create a glaze.

Spread the glaze over the top of the meatloaf and place it in the oven.

Bake for about 1 hour, or until the meatloaf reaches an internal temperature of 160°F (70°C).

Let the meatloaf rest for 10 minutes before slicing.
