Preheat your oven to 400 degrees Fahrenheit and position the rack in the center. Line your baking sheet with parchment paper.

Add the ground chicken, 1 cup mozzarella, Parmesan, egg, Italian seasoning, garlic powder, salt, and pepper to a large bowl. Ensure cheese is at room temperature for proper mixing.

Use your hands to combine everything thoroughly until no streaks of cheese remain visible, about 2 minutes of kneading. The mixture should feel cohesive rather than crumbly.

Transfer the mixture onto your prepared baking sheet and press it into a circle about 10 inches wide and 1/4 inch thick. Keep the edges slightly thicker than the center. Wet your hands periodically to stop the mixture from sticking.

Par bake the crust alone for 20 minutes until the edges turn golden brown and the surface looks dry.

Remove the crust from the oven and spread marinara sauce evenly across the surface, leaving about a half inch border.

Sprinkle the remaining 1 1/2 cups mozzarella cheese over the sauce, then arrange your pepperoni or other toppings.

Return the pizza to the oven and bake for an additional 10 minutes until the cheese melts completely and develops golden spots.

Let the pizza cool on the pan for 5 minutes before cutting. Garnish with fresh basil leaves and serve.
