Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish or casserole dish with cooking spray or butter.

In a large mixing bowl, combine the softened cream cheese, sour cream, mozzarella cheese, cheddar cheese, mayonnaise, garlic powder, onion powder, paprika, salt, and black pepper. Mix until smooth and well combined.

Fold the shredded halal chicken into the mixture, ensuring it is evenly coated with the creamy mixture.

Transfer the chicken mixture into the prepared baking dish, spreading it out evenly.

In a separate small bowl, mix the crushed Ritz crackers with melted butter until the crumbs are well coated.

Sprinkle the buttered cracker crumbs evenly over the chicken mixture in the baking dish.

Bake in the preheated oven for 30-35 minutes, or until the casserole is bubbling and the cracker topping is golden brown.

Remove from the oven and let it cool slightly before serving. Garnish with chopped parsley if desired.
