You’ll follow these easy steps to create Dolly’s Chicken and Stuffing Casserole:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Prepare the Chicken: If not yet done, shred your cooked chicken, ensuring no large pieces remain.
3. Sauté Vegetables: In a skillet over medium heat, melt the butter. Add the chopped onions and celery, sautéing until they’re tender (about 5-7 minutes).
4. Mix Ingredients: In a large bowl, combine the shredded chicken, sautéed vegetables, chicken broth, cream of chicken soup, garlic powder, thyme, black pepper, and salt. Mix well until all ingredients are thoroughly combined.
5. Prepare Stuffing: In a separate bowl, combine the stuffing mix with 1 cup of chicken broth, ensuring it is moistened but not overly soggy.
6. Assemble Casserole: In a greased 9×13 inch baking dish, layer the chicken mixture evenly across the bottom. Top this layer with the prepared stuffing, spreading it evenly over the chicken mixture.
7. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, or until golden brown and heated through.
8. Garnish: Once it’s done, remove the casserole from the oven and let it sit for 5 minutes. Garnish with fresh parsley before serving.

These straightforward instructions will enable even beginner cooks to prepare this delectable casserole with success.
