This hearty American casserole combines diced chicken breast with sautéed vegetables in a rich, creamy sauce. The dish is topped with buttery seasoned stuffing and baked until golden brown. With just 15 minutes of prep and 40 minutes in the oven, it's perfect for busy weeknight dinners or feeding a crowd. The filling bubbles up around the edges while the stuffing becomes irresistibly crispy on top. Serve with a simple green salad for a complete meal.
The smell of butter-toasted stuffing mingling with creamy sauce still takes me back to Tuesday nights at my grandmother's house. She'd call it 'something good' and we'd all come running from different corners of the neighborhood.
I first made this for a potluck when I was completely broke and had nothing but a rotisserie chicken and a box of stuffing. Three people asked for the recipe, and I've been making it on repeat ever since.
Ingredients
- 4 cups cooked chicken breast: Rotisserie chicken works perfectly here, or use leftover roasted chicken
- 1 cup each celery, onion, and carrots: Finely chopped so they soften nicely and blend into the creamy base
- 1 can cream of chicken soup: The backbone of the sauce, though homemade condensed soup works too
- 1 cup sour cream: Adds tang and richness that balances the salty stuffing
- 1/2 cup whole milk: Helps create that velvety texture we all want in comfort food
- 1/2 teaspoon garlic powder, thyme, pepper, and salt: Simple seasonings that let the chicken shine
- 1 package seasoned stuffing mix: Traditional herbed stuffing creates the best crispy crust
- 1/2 cup unsalted butter, melted: Essential for getting those golden, toasted edges
- 1 cup chicken broth: Moistens the stuffing just enough without making it soggy
Instructions
- Preheat your oven to 350°F and grease a 9x13-inch baking dish.
- This size gives you the perfect ratio of crispy topping to creamy filling.
- Sauté the vegetables until softened.
- Cook celery, onion, and carrots for about 7 minutes until they're fragrant and starting to turn translucent.
- Whisk together the sauce ingredients.
- Combine the soup, sour cream, milk, and seasonings until completely smooth.
- Combine chicken, vegetables, and sauce.
- Fold everything together gently so the chicken stays in nice chunks.
- Spread in the baking dish.
- Press it down lightly so there are no air pockets.
- Mix the topping.
- Combine stuffing, melted butter, and broth until every piece is lightly coated.
- Spread topping evenly.
- Cover the entire surface so no creamy filling shows through.
- Bake until golden.
- 35 to 40 minutes should give you beautifully toasted edges and bubbling sauce.
- Let it rest.
- Wait about 10 minutes before serving so the filling sets up slightly.
My husband claimed he didn't like casseroles until he tried this one. Now he requests it whenever the weather turns cold.
Making It Your Own
Turkey works just as well as chicken, especially after Thanksgiving. I've also added frozen peas or corn when I needed to stretch the recipe for unexpected guests.
Make-Ahead Magic
Assemble everything up to the baking step, cover tightly, and refrigerate for up to 24 hours. Add 5 to 10 minutes to the baking time since it will be cold.
Leftovers That Actually Reheat Well
Individual portions microwave beautifully and the topping somehow stays crispy. You can also freeze the whole casserole unbaked, then thaw overnight in the refrigerator before baking.
- Portion leftovers into containers before reheating for even heating
- Add a splash of broth when reheating if it seems dry
- The flavors actually improve after a day in the refrigerator
This is the kind of recipe that makes a house feel like home, no matter what day of the week it is.
Recipe FAQ
- → Can I make this ahead of time?
-
Yes, assemble the entire casserole up to 24 hours in advance and refrigerate. Add 5-10 minutes to baking time if baking cold from the refrigerator.
- → Can I freeze this casserole?
-
Freeze before baking by wrapping tightly in plastic and foil. Thaw overnight in refrigerator before baking. Alternatively, freeze leftovers in individual portions for up to 3 months.
- → What can I substitute for cream of chicken soup?
-
Try cream of mushroom soup, homemade white sauce, or a mixture of chicken broth and heavy cream thickened with flour. Each adds a slightly different flavor profile.
- → How do I know when it's done baking?
-
The casserole is ready when the stuffing top is golden brown and crispy, and you see the creamy filling bubbling around the edges. The internal temperature should reach 165°F.
- → Can I use raw chicken instead of cooked?
-
No, use pre-cooked chicken. Raw chicken won't cook through safely in the 40-minute baking time. Rotisserie chicken works perfectly and saves time.
- → How do I make this healthier?
-
Use low-fat sour cream and reduced-fat soup. Add extra vegetables like peas or green beans. Increase the vegetable-to-chicken ratio for more nutrients and fewer calories per serving.
