Preheat oven to 400°F. Line a large baking sheet with parchment paper. In a large bowl, stir together ground chicken, ½ cup parmesan, optional seasonings, and garlic, and season with salt and pepper.
Spray prepared baking sheet with cooking spray. Form chicken mixture into a large round crust, about 1/2” thick.
Bake until chicken is cooked through and golden, 20 to 22 minutes. Remove from oven and heat broiler.
Spread a thin layer of sauce, leaving a small border around the circumference of the pizza. Top with mozzarella and broil until cheese is melted, 3 to 4 minutes. Garnish with more Parmesan, if desired.
