Preheat your oven to 375°F (190°C). Lightly grease a loaf pan or line it with parchment paper to prevent sticking during baking.

Finely chop the onion and mince the garlic cloves. Smaller pieces blend better into the meat mixture and create even flavor.

Place breadcrumbs, salt, black pepper, paprika, and dried parsley into a large bowl. Mix well so the seasonings distribute evenly.

Add eggs, milk, and Worcestershire sauce to the bowl. Stir gently until everything combines into a moist mixture.

Place the ground beef into the bowl. Mix gently using clean hands or a spoon. Avoid overmixing to keep the meatloaf tender.

Transfer the mixture into the prepared loaf pan. Press lightly to shape it evenly without making it too compact.

In a small bowl, combine ketchup, brown sugar, and mustard. Stir until smooth and fully blended.

Spread the glaze evenly across the top of the meatloaf. This creates a sweet and savory coating during baking.

Place the pan in the oven and bake for about 60 minutes. The internal temperature should reach 160°F (71°C).

Remove the meatloaf from the oven. Let it rest for 10 minutes before slicing. This helps retain moisture and flavor.
