Preheat your oven to 350°F (175°C). Gather a large mixing bowl.

Combine softened cream cheese, cottage cheese, sour cream, mayonnaise, and cream of chicken soup in the mixing bowl. Mix until smooth.

Stir in garlic powder, onion powder, salt, and pepper into the creamy mixture.

Fold in the cooked chicken until evenly coated.

Grease a 9x13-inch baking dish and spread the chicken mixture evenly.

Sprinkle Parmesan cheese over the chicken mixture.

In a small bowl, mix crushed Ritz crackers with melted butter until fully coated.

Spread the buttery cracker mixture over the Parmesan cheese, then add shredded mozzarella on top.

Bake for 25-30 minutes until bubbly and golden brown.

Let the casserole cool for about 10 minutes before serving, then garnish with fresh parsley.
