Begin by preheating your oven to 350°F (175°C). Lightly grease your loaf pan or line it with parchment paper for easy cleanup.
In a large mixing bowl, combine the ground turkey, breadcrumbs, grated Parmesan cheese, chopped fresh parsley, chopped onion, minced garlic, eggs, dried oregano, dried basil, salt, and black pepper. Pour in the milk last. Use your hands or a spatula to gently mix until just combined—avoid overmixing to keep the meatloaf tender.
Transfer the mixture to your prepared loaf pan, pressing it down evenly. Smooth the top with a spatula or the back of a spoon to create a neat shape.
Spread the ketchup evenly over the top of the meatloaf. This glaze will caramelize slightly during baking, adding a delicious tang and moisture.
Bake the meatloaf in the preheated oven for about 50-60 minutes, or until the internal temperature reaches 165°F (74°C). Let it rest for 10 minutes before slicing to allow the juices to redistribute.
