This one-skillet chicken and dumpling casserole turns a cozy classic into a weeknight dinner you can pull off without stirring a pot of soup. Tender chicken, peas, and carrots swim in a creamy sauce, all topped with fluffy, golden dumplings that bake up right on top.

It’s the kind of meal that needs nothing more than a spoon and a seat at the table. And because everything cooks in one skillet, cleanup is almost as comforting as the first bite.

Why This Casserole Works

The sauce is rich without being heavy, thanks to a mix of broth and a little cream. It coats every bite of chicken and vegetable without tasting weighed down.

Baking the dumplings instead of simmering them gives you a crisp top and a tender, biscuit-like center that soaks up just enough sauce. You get the best parts of chicken and dumplings with almost no stirring once it hits the oven.

I keep coming back to this one because it uses cooked or rotisserie chicken, so the active time is short enough for a Tuesday. You can have it on the table in under an hour with minimal fuss.

Ingredients

3 tbsp butter: salted or unsalted, whatever you keep on hand
1 small yellow onion, diced: about 1 cup
2 medium carrots, peeled and sliced into thin coins
2 celery ribs, thinly sliced
2 garlic cloves, minced
¼ cup all-purpose flour: for thickening the sauce
2 cups chicken broth: low-sodium lets you control the salt
½ cup heavy cream: makes the sauce velvety
1 tsp dried thyme
½ tsp salt, plus more to taste
¼ tsp black pepper
2 cups cooked shredded chicken: rotisserie chicken is a great shortcut
1 cup frozen peas: no need to thaw
1½ cups all-purpose flour: for the dumplings
2 tsp baking powder
½ tsp salt
4 tbsp cold unsalted butter, cut into small cubes
¾ cup whole milk: cold milk keeps the butter firm

Variations and Substitutions

Swap the protein: Leftover turkey works as well as chicken.
Change the vegetables: Corn, green beans, or a handful of chopped spinach can replace the peas.
Herb it up: Fresh thyme or a pinch of rosemary adds a different layer of warmth.
No heavy cream: Use an extra ½ cup of broth with 1 tablespoon of butter stirred in at the end.
Dairy-free: Use a plant-based milk and a good vegan butter for both the sauce and dumplings.

How to Make One-Skillet Creamy Chicken and Dumpling Casserole

Step 1: Sauté the Vegetables and Build the Roux

Preheat the oven to 400°F (200°C). Melt the 3 tablespoons butter in a 10-inch oven-safe skillet over medium heat. Add the onion, carrots, and celery and cook, stirring occasionally, until softened, about 5 minutes.

The veggies should be glossy and starting to sweeten in the butter, not browning too deeply. Stir in the garlic and cook for 30 seconds, just until fragrant.

Step 2: Stir in the Broth and Cream

Sprinkle the ¼ cup flour over the vegetables and cook, stirring constantly, for 1 minute. The flour will smell lightly toasty and turn a shade darker.

Slowly pour in the 2 cups broth while whisking to prevent lumps, then add the ½ cup cream, thyme, ½ teaspoon salt, and pepper. Bring to a gentle simmer and cook, stirring often, until the sauce thickens enough to coat the back of a spoon, 3 to 4 minutes.

Step 3: Fold in the Chicken and Peas

Remove the skillet from the heat. Stir in the 2 cups shredded chicken and 1 cup frozen peas until everything is evenly coated in the sauce.

Spread the filling into an even layer so the dumplings have a flat surface to sit on. The sauce will still be fairly loose at this stage; it thickens more as it bakes.

Step 4: Drop the Dumpling Topping

In a medium bowl, whisk together the 1½ cups flour, baking powder, and ½ teaspoon salt. Cut in the 4 tablespoons cold butter using a pastry blender or your fingers until the mixture looks like coarse crumbs with a few pea-sized bits of butter remaining. Pour in the ¾ cup milk and stir just until no dry flour remains. The dough will be thick and sticky.

Drop heaping spoonfuls of the dough over the filling, leaving small gaps for steam to escape. Do not worry about making the dumplings neat; the rustic shapes brown beautifully and keep the centers tender.

Step 5: Bake the Casserole Until Golden

Bake until the dumplings are puffed and deep golden on top and the sauce is bubbling at the edges, 20 to 25 minutes. Let the casserole rest for 5 minutes before serving, which helps the sauce settle and makes scooping easier. Spoon into bowls while it is still steaming.

Tips for the Fluffiest Dumplings

Keep the butter cold and work fast. Cold butter creates pockets of steam that lift the dumplings as they bake.
Stir the dumpling dough only until the flour disappears. Overmixing makes the topping dense instead of light.
If you do not have an oven-safe skillet, cook the filling in a regular skillet, then transfer it to a greased 9×13-inch baking dish before adding the dumplings and baking.
For a bit more color on top, broil the casserole for the last minute, but watch it closely so the dumplings do not burn.

Bake times by skillet size:

Skillet Size	Dumpling Thickness	Bake Time
9-inch	A bit thicker	25 to 30 mins
10-inch	Thinner, wider	20 to 25 mins
12-inch	Thinnest	18 to 22 mins

Storing and Reheating Leftovers

Refrigerate any leftovers in an airtight container for up to 3 days. The dumplings will soften in the fridge, but the flavor holds beautifully. Reheat in a 350°F oven until warmed through, about 15 minutes, to bring back some of the topping’s texture. A microwave works in a pinch, though the dumplings will be softer.

What to Serve with Chicken and Dumpling Casserole

A simple green salad with a sharp lemon vinaigrette cuts through the richness of the casserole. Steamed green beans or roasted asparagus tossed with a little olive oil also work, adding a crisp, fresh bite alongside each creamy spoonful.

Frequently Asked Questions

Can I use biscuit mix for the dumplings?

Yes, replace the flour, baking powder, salt, and butter with 2 cups of biscuit mix. Stir in the ¾ cup milk until just combined.

Can I make the filling ahead of time?

You can cook the filling up to a day ahead and refrigerate it. Reheat it gently on the stovetop until bubbling, then top with the dumplings and bake. Do not add the dumplings until you are ready to bake.

Can I freeze this casserole?

I do not recommend freezing it. The dumplings turn soggy and the sauce may separate when thawed and reheated.

What other vegetables can I use?

Corn, cut green beans, or sautéed mushrooms all work well. Just keep the total vegetable amount about the same so the sauce-to-filling ratio stays balanced.
