01 - Preheat oven to 375°F. Lightly grease a medium casserole dish with cooking spray or butter.
02 - In a large bowl, mix cooked chicken, softened cream cheese, half the mozzarella, half the Parmesan, Italian herbs, garlic powder, salt, and pepper until thoroughly combined.
03 - Spread the chicken mixture evenly in the prepared casserole dish, pressing down lightly to create an even layer.
04 - Pour the marinara sauce over the chicken layer, spreading gently with a spoon to cover evenly.
05 - Sprinkle the remaining mozzarella and Parmesan evenly over the sauce layer.
06 - Scatter crushed pork rinds over the cheese for added texture, if desired.
07 - Bake for 25–30 minutes, or until the casserole is bubbling around the edges and the cheese is golden brown.
08 - Let cool for 5 minutes before serving. Garnish with fresh chopped basil and serve hot.
