In a large mixing bowl, combine the shredded rotisserie chicken, stuffing mix, frozen peas and carrots, cream of chicken soup, sour cream, milk, dried thyme, garlic powder, salt, and pepper. Mix well until all ingredients are evenly distributed.
2. Assemble the Casserole
Lightly grease a 9×13-inch baking dish with cooking spray or a little butter.
Pour the chicken and stuffing mixture into the prepared baking dish and spread it out evenly.
If using, sprinkle the shredded cheddar cheese evenly over the top of the casserole.
3. Bake the Casserole
Drizzle the melted butter over the top of the casserole.
Bake in the preheated oven for 30-35 minutes, or until the casserole is hot and bubbly and the top is golden brown. If you added cheese, it should be melted and slightly browned.
4. Serve
Remove the casserole from the oven and let it cool for a few minutes before serving.
Garnish with chopped fresh parsley if desired.
