Prepare the Aromatics: Start by heating 2 tablespoons of olive oil in a medium skillet over medium heat. Add 80g of finely diced onion and 2 cloves of minced garlic, sautéing for about 5-7 minutes until the onion is translucent and softened. Remove from heat and let the mixture cool for a few minutes while you prepare the meatloaf mixture.

Mix the Meatloaf: In a large mixing bowl, combine 900g of ground chicken, the cooled onion and garlic mixture, 60g of seasoned breadcrumbs, 2 teaspoons of milk, 30g of grated Parmesan cheese, 1 egg, 2 tablespoons of chopped fresh parsley, 1 teaspoon of Italian seasoning, and ½ teaspoon of salt. Use your hands or a spoon to mix everything gently until just combined, taking care not to overmix.

Shape the Meatloaf: Preheat your oven to 200°C (400°F). Line a baking sheet with parchment paper. Transfer the chicken mixture onto the prepared sheet and shape it into a loaf, roughly 20cm x 10cm. Create a shallow trench along the center and place the mozzarella strings (cut into 1cm slices) inside, then carefully fold the mixture over and seal it, ensuring the cheese is fully enveloped.

Bake with Marinara: Spread 120ml of marinara sauce evenly over the top of the shaped meatloaf. Bake in the preheated oven for 45 minutes, or until the meatloaf is golden and the internal temperature reaches about 74°C (165°F). Keep an eye on the edges; they should be slightly crispy and the sauce bubbling.

Add the Topping: In a small bowl, combine 2 tablespoons of panko breadcrumbs, an additional 30g of grated Parmesan cheese, 20g of melted butter, and the remaining chopped parsley. After 45 minutes of baking, sprinkle shredded mozzarella (120g) on top, followed by the breadcrumb mixture. Return the meatloaf to the oven for another 15-20 minutes, until the topping is golden and crispy.

Rest & Serve: Once baked, remove the Parmesan Chicken Meatloaf from the oven and let it rest for 10 minutes before slicing. This resting period ensures that the juices redistribute, giving you perfectly moist slices. Serve warm, with your favorite sides, and enjoy the delicious flavors of this comforting dish.
