1. Prep the Oven and Pan:
Preheat your oven to 375°F (190°C). Lightly grease a 9×5-inch loaf pan or line it with parchment paper for easy removal.
2. Mix the Meatloaf:
In a large bowl, combine the ground chicken, breadcrumbs, Parmesan cheese, egg, milk, garlic, onion, parsley, Italian seasoning, salt, and pepper. Use a fork or your hands to mix until the ingredients are just combined. Be careful not to overmix, as this will result in a denser meatloaf.
3. Form the Loaf:
Transfer the mixture to the prepared loaf pan. Gently press it down to form an even loaf, but avoid packing it too tightly. A gentle touch is the secret to a tender texture.
4. Initial Bake:
Place the meatloaf in the preheated oven and bake, uncovered, for 40-45 minutes. The edges will be golden brown, and the internal temperature should be close to 165°F (74°C).
5. Add the Topping:
Remove the meatloaf from the oven. If using the topping, carefully spread the marinara sauce evenly over the top, then sprinkle with the shredded mozzarella. Return the pan to the oven and bake for another 10-15 minutes, or until the cheese is melted and bubbly and the internal temperature in the center of the loaf reaches 165°F (74°C).
6. Rest and Serve:
Let the meatloaf rest in the pan for 5-10 minutes before slicing. This allows the juices to redistribute, making it easier to cut. Garnish with extra parsley or Parmesan if desired, and serve warm.
Perfect Pairing: This meatloaf is wonderful with creamy mashed potatoes, roasted vegetables, or a fresh green salad.
