Preheat your oven to 375°F (190°C) and prepare a baking sheet with foil and cooking spray.

In a large mixing bowl, combine ground beef, breadcrumbs, eggs, milk, onion, garlic, salt, black pepper, Italian seasoning, and parsley until just mixed.

Shape the meat mixture into a rectangle, place mozzarella sticks in the center, and roll the meat around the cheese, sealing the edges.

Wrap the meatloaf with overlapping bacon slices, tucking any overhanging pieces underneath.

Mix ketchup, brown sugar, and Worcestershire sauce to create the glaze. Brush half over the meatloaf.

Bake for 45 minutes, then brush with remaining glaze and bake for an additional 15-20 minutes, until internal temperature reaches 160°F (71°C).

Let the meatloaf rest for 10 minutes, then slice and serve.
