Chicken & Dressing Casserole

There are few comfort foods quite as satisfying as a bubbling casserole fresh from the oven, and Chicken & Dressing Casserole is one of those dishes that feels like home from the very first bite. Tender chicken, savory herb-seasoned dressing, creamy sauce, and a golden baked top come together in one hearty dish that is perfect for a family dinner, Sunday supper, or holiday-inspired meal.

This casserole is especially useful when you want the comforting flavors of traditional chicken and dressing without preparing an entire elaborate meal. The ingredients are simple, the preparation is straightforward, and everything bakes together until the top is golden and the center is wonderfully moist.

Why You’ll Love This Chicken & Dressing Casserole

This recipe combines several classic comfort-food qualities in one pan. The chicken provides plenty of protein and a tender, savory bite, while the dressing absorbs the creamy sauce and chicken juices as it bakes.

The result is a casserole with a soft, flavorful center and a lightly crisp, golden surface. A little poultry seasoning, sage, onion, and celery give the dish that familiar dressing flavor without overpowering the chicken.

It is also an excellent make-ahead meal. You can assemble much of the casserole in advance, refrigerate it, and bake it when you’re ready for dinner.

Ingredients

For the Chicken

3 cups cooked, shredded chicken
2 tablespoons butter
1 small onion, finely diced
2 celery stalks, finely diced
1/2 teaspoon salt
1/4 teaspoon black pepper

For the Dressing

6 cups crumbled cornbread, preferably slightly dried
1 teaspoon poultry seasoning
1/2 teaspoon dried sage
1/2 teaspoon black pepper
2 cups chicken broth
1 large egg, lightly beaten

For the Creamy Mixture

1 can (10.5 ounces) cream of chicken soup
1/2 cup sour cream
1/2 cup chicken broth
1/2 teaspoon garlic powder
1/4 teaspoon black pepper

For the Top

1 tablespoon melted butter
A small pinch of dried sage or poultry seasoning, optional

Step 1: Prepare the Chicken

Start with cooked chicken that has been cooled enough to handle. Shred it into bite-sized pieces using two forks or your hands.

Rotisserie chicken works particularly well for this recipe because it is already seasoned and tender. You can also use leftover roasted or baked chicken.

Try not to shred the chicken too finely. Slightly larger pieces give the casserole a better texture and make the chicken more noticeable in every serving.

Set the shredded chicken aside while you prepare the vegetables and dressing.

Step 2: Sauté the Onion and Celery

Preheat your oven to 375°F (190°C).

Melt the butter in a skillet over medium heat. Add the diced onion and celery and cook for approximately 5–7 minutes, stirring occasionally.

The vegetables should become tender and fragrant without becoming deeply browned.

Season them lightly with salt and black pepper. Once softened, remove the skillet from the heat.

This small step makes a big difference because sautéing the vegetables first allows their flavor to become sweeter and more developed before they go into the casserole.

Step 3: Make the Dressing Mixture

Place the crumbled cornbread in a large mixing bowl.

Add the poultry seasoning, dried sage, and black pepper. Toss everything together so the seasonings are distributed evenly.

Pour in the chicken broth gradually, stirring as you go. You want the cornbread to become moist but not completely mushy.

Next, add the lightly beaten egg and stir gently until incorporated.

The dressing mixture should be moist enough to hold together when pressed but still retain some texture.

Step 4: Prepare the Creamy Sauce

In a separate bowl, combine the cream of chicken soup, sour cream, chicken broth, garlic powder, and black pepper.

Whisk until smooth.

The sour cream adds a subtle tanginess that balances the richness of the soup, while the chicken broth helps loosen the mixture so it can spread easily throughout the casserole.

If the mixture seems especially thick, add another tablespoon or two of chicken broth.
