Ingredients
Method
- Preheat Oven: Set oven to 375°F and grease a 9×13-inch baking dish.
- Sauté Vegetables: Melt butter in a skillet over medium heat. Add onion and celery; sauté for 4–5 minutes until soft and fragrant.
- Mix Filling: In a large bowl, combine cooked chicken, sautéed vegetables, frozen veggies, cream of chicken soup, chicken broth, garlic powder, thyme, salt, and pepper. Mix well.
- Assemble Base: Spread chicken mixture evenly into the prepared baking dish.
- Prepare Stuffing: Make stuffing per package directions and spread evenly over the chicken mixture.
- Bake: Bake uncovered for 30–35 minutes until stuffing is golden brown and casserole is bubbling around the edges.
- Rest: Let sit for 5 minutes before serving for best consistency.
Notes
For a make-ahead version, assemble casserole up to 24 hours in advance and refrigerate. Add 10–15 minutes to the baking time when cooking from cold. Freeze leftovers for up to 3 months for quick weeknight meals.
