Preheat oven to 350°F. In a medium bowl stir together soup, cottage cheese, cream cheese, sour cream, Italian seasoning, and garlic powder.
Stir in chicken and the sliced ½ cup green onions. Spoon chicken mixture into a 2-quart square baking dish.
Stir together crackers and melted butter. Sprinkle over chicken mixture.
Bake until chicken mixture is heated through (160°F) and crackers are golden brown, about 40 minutes. Let stand 10 minutes. Top with 2 Tbsp. sliced green onions.
