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 black pepper. Stir until evenly incorporated.
03 - Spread the chicken mixture evenly across the bottom of the prepared casserole dish, pressing gently to create a uniform layer.
04 - Pour the sugar-free marinara sauce over the chicken layer, spreading gently with a spoon to cover completely.
05 - Sprinkle the remaining mozzarella and Parmesan cheeses evenly over the sauce layer.
06 - Scatter crushed pork rinds over the cheese for extra texture and crunch.
07 - Bake for 25–30 minutes, or until the casserole is bubbly around the edges and the cheese topping is golden brown.
08 - Let the casserole cool for 5 minutes before serving. Garnish with chopped fresh basil and serve hot.
