Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish.

In a large bowl, mix shredded chicken, cream of chicken soup, and sour cream until smooth. Add garlic powder, onion powder, salt, and pepper to taste.

Pour the chicken mixture into the prepared baking dish and spread it evenly across the bottom.

In a separate bowl, combine stuffing mix with melted butter and gradually stir in chicken broth until the stuffing is moist but not soggy.

Spoon the stuffing mixture over the chicken layer and spread evenly.

Bake uncovered for 35–40 minutes until the top is golden brown and the edges are bubbling.

Let the casserole rest for 5–10 minutes before serving.
