This hearty baked dish combines diced chicken breast with sautéed celery, onion, and carrots in a rich, creamy sauce. The base gets covered with buttery seasoned stuffing and baked until beautifully golden and bubbling. Ready in under an hour, it's perfect for feeding a hungry family.
The first time my neighbor Dolly brought this casserole over, my kitchen smelled like butter and thyme for three days straight. She laughed when I asked for the recipe, saying it was just \"something thrown together\" but those are always the dishes that stick. Now it\'s the only casserole my actually requests by name.
Last winter when my sister had her tonsils out, I made a triple batch and froze individual portions. She texted me later saying it was the only thing she could taste and actually enjoy. Sometimes the simplest food is what we need most.
Ingredients
- 4 cups cooked chicken breast: Rotisserie chickens work perfectly here and save so much time
- 1 cup celery, finely chopped: Fresh celery adds a subtle crunch that complements the soft stuffing
- 1 cup yellow onion, finely chopped: Yellow onions become sweet and mellow when sautéed
- 1 cup carrots, finely chopped: Finely diced carrots cook through evenly and add color
- 1 can (10.5 oz) condensed cream of chicken soup: This creates the velvety base that holds everything together
- 1 cup sour cream: Full-fat sour cream adds richness and a slight tang
- 1/2 cup whole milk: Whole milk makes the sauce silky without being too heavy
- 1/2 teaspoon garlic powder: A background note that deepens the savory flavors
- 1/2 teaspoon dried thyme: Thyme pairs beautifully with poultry and cream
- 1/2 teaspoon black pepper: Freshly ground gives the best aroma and flavor
- 1/2 teaspoon salt: Adjust based on whether your chicken was salted
- 1 package (6 oz) seasoned stuffing mix: Traditional herb stuffing mix creates the perfect crispy topping
- 1/2 cup unsalted butter, melted: Butters the stuffing and helps it golden beautifully
- 1 cup low-sodium chicken broth: Low-sodium lets you control the salt level
Instructions
- Preheat your oven and prepare the baking dish:
- Set your oven to 350°F and lightly butter a 9x13-inch baking dish so nothing sticks later.
- Sauté the vegetables:
- Cook the celery, onion, and carrots in a skillet with a little butter or oil until they\'re softened and fragrant, about 5 to 7 minutes.
- Make the creamy sauce base:
- Whisk together the cream of chicken soup, sour cream, milk, garlic powder, thyme, pepper, and salt until completely smooth.
- Combine the chicken and vegetables:
- Fold the cooked chicken and sautéed vegetables into the sauce mixture until everything is evenly coated.
- Transfer to the baking dish:
- Spread the chicken mixture evenly across the prepared baking dish in a smooth layer.
- Prepare the stuffing topping:
- Mix the stuffing mix, melted butter, and chicken broth in a bowl until the stuffing is evenly moistened.
- Add the crispy topping:
- Sprinkle the stuffing mixture over the chicken layer, covering it completely.
- Bake until golden and bubbling:
- Bake for 35 to 40 minutes until the top is golden brown and you see bubbles around the edges.
- Let it rest before serving:
- Wait 5 to 10 minutes before serving so the casserole sets and makes serving easier.
My daughter started making this for her college roommates and now they request it for every birthday dinner. Recipes that travel from generation to generation carry more than just ingredients.
Make Ahead Magic
You can assemble this casserole up to 24 hours in advance and refrigerate it before baking. Add about 10 extra minutes to the baking time since it will be cold. The flavors actually meld better when given time to sit.
Freezer Friendly
This casserole freezes beautifully either before or after baking. Wrap tightly in foil and freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed.
Serving Suggestions
A crisp green salad with vinaigrette cuts through the richness perfectly. Roasted green beans or steamed broccoli also work wonderfully alongside.
- Warm some crusty bread to soak up any extra sauce
- A light white wine like Pinot Grigio pairs nicely
- Keep leftovers for an easy lunch the next day
Simple comfort food like this reminds us that a warm meal can fix almost anything. Enjoy every bite.
