Begin by preheating your oven to 375°F (190°C). Grease a loaf pan lightly with olive oil to prevent sticking.
In a large mixing bowl, combine the ground chicken, breadcrumbs, grated Parmesan cheese, minced garlic, finely chopped onion, and freshly chopped parsley. Mix these ingredients until evenly distributed.
In a separate small bowl, crack the egg and whisk it together with the Worcestershire sauce, garlic powder, oregano, salt, and black pepper. Ensure the mixture is well combined and smooth.
Pour the egg mixture over the chicken mixture in the large bowl. Using your hands or a spatula, thoroughly mix all the ingredients until they are evenly combined, avoiding overmixing to keep the meatloaf tender.
Transfer the meat mixture into the prepared loaf pan, shaping it into a loaf form with your hands for a uniform look.
Generously spread the ketchup over the top of the meatloaf, creating a sweet and tangy glaze that will caramelize during baking.
Place the loaf pan in the preheated oven and bake for 45-50 minutes. Use a meat thermometer to ensure the internal temperature reaches 165°F (74°C) for safe consumption.
After baking, remove the meatloaf from the oven and let it rest for approximately 10 minutes. This will allow the juices to redistribute, ensuring a moist and flavorful slice.
Notes
For an appetizing presentation, slice the meatloaf and arrange it on plates. Garnish with a sprinkle of chopped parsley and serve with mashed potatoes or steamed vegetables.
