In a large bowl, combine the ground turkey, breadcrumbs, chopped onion, minced garlic, parsley, thyme, milk, egg, Worcestershire sauce, salt, pepper, and smoked paprika.
If using mozzarella cheese, fold it into the mixture.
Using your hands (or a spatula), mix everything together until well combined, but do not overmix as this can make the meatloaf dense.
Transfer the mixture to a loaf pan and shape it gently, creating an even surface.
Spread a layer of ketchup or BBQ sauce on top for extra flavor and moisture.
Bake in the preheated oven for 50-60 minutes, or until the internal temperature reaches 165°F (74°C).
Let the meatloaf sit for 10 minutes before slicing to allow the juices to redistribute.
Serve warm and enjoy!
Notes
Let the meatloaf rest before slicing to keep it juicy.
