Preheat the oven to 350 degrees Fahrenheit. Add cooked chicken, sour cream, cream of chicken soup, shredded parmesan cheese, and poppy seeds in a large bowl. Mix until incorporated. Spread along the bottom of a 2-quart casserole or 9x9 inch pan.
Crush the Ritz crackers, add melted butter, and toss to coat in the butter. Sprinkle on top of the chicken mixture. Bake for 25-30 minutes or until bubbly.
