Begin by preheating your oven to 350°F (175°C) to ensure it's perfectly heated for baking.
In a large mixing bowl, combine the ground beef with the breadcrumbs, finely chopped onion, minced garlic, grated Parmesan cheese, shredded mozzarella cheese, and fresh parsley.
Add the eggs, Worcestershire sauce, dried oregano, dried thyme, salt, and black pepper to the mixture.
Using your hands or a fork, mix all the ingredients together until they are evenly combined. Be careful not to overmix, as this can make the meatloaf tough.
Shape the combined mixture into a loaf shape and transfer it into a greased 9x5-inch loaf pan, pressing it gently to ensure it holds its shape.
Generously spread the ketchup over the top of the meatloaf, creating a flavorful glaze that will enhance its taste.
Place the loaf pan in the preheated oven and bake for 45-55 minutes, or until the meatloaf is fully cooked and achieves an internal temperature of 160°F (70°C).
After baking, let the meatloaf rest for about 10 minutes before slicing. This resting period allows the juices to redistribute, ensuring a moist and flavorful loaf.
Serve the meatloaf warm, with extra ketchup on the side if desired, complemented by your favorite vegetables or creamy mashed potatoes for a hearty meal.
Notes
Let the meatloaf rest before slicing for better texture.
