01 - Preheat oven to 375°F. Lightly grease a medium casserole dish with cooking spray or butter.
02 - Combine cooked chicken, softened cream cheese, half the mozzarella, half the Parmesan, Italian herbs, garlic powder, salt, and pepper in a large bowl. Mix thoroughly until well incorporated.
03 - Spread the chicken mixture evenly across the bottom of the prepared casserole dish, pressing down lightly to create a uniform layer.
04 - Pour the sugar-free marinara sauce over the chicken layer, spreading gently with a spoon to cover the entire surface evenly.
05 - Distribute the remaining mozzarella and Parmesan cheese uniformly over the sauce layer, ensuring complete coverage.
06 - Scatter crushed pork rinds over the cheese layer for added texture and golden crunch.
07 - Bake for 25 to 30 minutes until the casserole bubbles vigorously around the edges and the cheese topping develops a deep golden-brown color.
08 - Remove from oven and let rest for 5 minutes to set. Sprinkle with fresh chopped basil just before serving hot.
