01 - Preheat oven to 375°F. Lightly grease a medium casserole dish with cooking spray or butter.
02 - In a large bowl, combine cooked chicken, softened cream cheese, half the mozzarella, half the Parmesan, Italian herbs, garlic powder, salt, and pepper. Mix thoroughly until all ingredients are evenly distributed.
03 - Spread the chicken mixture evenly across the bottom of the prepared casserole dish, pressing lightly to create a uniform layer.
04 - Pour the marinara sauce over the chicken layer. Use a spoon or spatula to spread gently, covering the entire surface.
05 - Sprinkle the remaining mozzarella and Parmesan cheeses evenly over the sauce layer.
06 - Scatter crushed pork rinds over the cheese layer for added texture and crunch.
07 - Bake for 25–30 minutes, or until the casserole is bubbling around the edges and the cheese has developed a golden-brown color.
08 - Remove from oven and let rest for 5 minutes to set. Garnish with fresh chopped basil and serve hot.
