Preheat the oven to 375°F. Line a large baking sheet with parchment paper. Set aside.
In a large bowl, combine the ground chicken, Parmesan cheese, flour, eggs, minced garlic, Italian seasoning, salt and pepper. Mix until just combined. Be careful not to over mix.
Divide the mixture into 8 equal portions and shape each into a small loaf. Place the loaves, spaced a few inches apart, on the prepared baking sheet.
Bake in the preheated oven for 25 minutes. Remove from the oven. Spread a spoonful of marinara over each meatloaf, then sprinkle with 2 Tablespoons of freshly grated mozzarella cheese over the tops.
Place back in the oven and bake for an additional 5 minutes to allow the cheese to melt. (Meatloaves are done when the internal temperature reaches 165°F.) Top each meatloaf with a sprinkle of fresh parsley, if desired. Serve warm and enjoy!
