This chicken cornbread casserole is a creamy chicken and corn filling baked under a golden layer of sweet cornbread. It tastes a lot like chicken pot pie, but instead of rolling out a crust, you just stir up a box of cornbread mix and spread it on top.

It is a great way to use leftover or rotisserie chicken. The prep takes about 10 minutes, and most of the ingredients are pantry staples. No weird ingredients, no complicated steps. You get a warm, filling dinner from one baking dish, ready in about 45 minutes.

Why This Chicken Cornbread Casserole Works

Cream of chicken soup thinned with a little milk makes a quick, savory sauce. It is thick enough to hold the chicken and corn together, but loose enough to stay creamy under the topping. Since the chicken is already cooked, the oven only needs to heat the filling and bake the cornbread.

The cornbread batter goes on raw and bakes right on top of the hot filling. The bottom of the cornbread soaks up a little of the sauce and turns soft and tender, while the top gets a golden, slightly crisp crust. The touch of sweetness in the cornbread balances the salty, creamy filling, which is what makes this dish so easy to like.

Ingredients and Easy Swaps

Cooked chicken: You need 3 cups chopped or shredded. A store-bought rotisserie chicken gives you about that much. Leftover roasted chicken, grilled chicken, or even leftover turkey all work.

Cream of chicken soup and milk: One 10.5-ounce can plus 1/2 cup milk. Cream of mushroom or cream of celery work the same way. Any milk is fine, and chicken broth works if you are out of milk.

Frozen corn: Add it straight from the bag. A cup of frozen mixed vegetables (peas, carrots, corn, and green beans) makes it feel even more like pot pie.

Onion powder, salt, and pepper: Keep the salt light at first. Canned soup and rotisserie chicken are already salty. Taste the filling before you add more.

Cornbread mix: An 8.5-ounce box like Jiffy is the easiest choice. Mix it with whatever the box calls for, usually 1 egg and 1/3 cup milk. Any brand of cornbread mix works, or you can use your own favorite homemade cornbread batter.

How to Make It at a Glance

1. Heat the oven to 375°F and grease a 9×13-inch baking dish.
2. Stir the soup, milk, onion powder, salt, pepper, chicken, and corn together.
3. Spread the filling in the baking dish.
4. Mix the cornbread batter according to the box and spread it over the filling.
5. Bake for 30 to 35 minutes, until the cornbread is golden and a toothpick in the center comes out clean.

Common Mistakes to Avoid

Pouring the batter in one spot. Spoon the cornbread batter on in small dollops all over the filling, then gently spread them together with the back of a spoon. This keeps the topping even so it bakes at the same rate.

Pulling it too early. The cornbread can look golden on top while the center is still wet. Check the middle with a toothpick. If batter sticks to it, bake 5 more minutes.

Over-salting the filling. Between the soup and a rotisserie chicken, there is plenty of salt already. Add pepper freely, but go easy on salt.

Serving it right away. Let it rest 5 to 10 minutes after baking. The filling thickens as it cools slightly, so it doesn’t run all over the plate.

Variations

Cheesy: Stir 1 cup shredded cheddar into the filling, or sprinkle it over the cornbread batter before baking.

Tex-Mex: Add a 4-ounce can of diced green chiles and 1 teaspoon chili powder to the filling. Use pepper jack cheese and serve with salsa.

Pot pie style: Use frozen mixed vegetables instead of corn and add 1/2 teaspoon dried thyme.

Thicker topping: Use two boxes of cornbread mix for a thick, cakey layer. Add 5 to 10 minutes to the bake time.

What to Serve With It

This casserole already has protein, a vegetable, and bread, so a light side is all you need. A crisp green salad with ranch or a simple vinaigrette is a good match. Steamed green beans, roasted broccoli, or sliced fresh tomatoes with salt and pepper all work. Applesauce is an easy side that pairs well with the sweet cornbread.

Make Ahead, Storage, and Reheating

You can make the filling up to 1 day ahead and keep it covered in the fridge. Mix the cornbread batter right before baking, since it loses its rise if it sits. Add about 10 minutes to the bake time when the filling starts cold.

Leftovers keep covered in the fridge for 3 to 4 days. You can freeze the baked casserole, whole or in portions, for up to 3 months. Wrap it tightly in plastic wrap and foil, and thaw it overnight in the fridge.

Reheat portions in the microwave for 1 to 2 minutes. For a larger amount, cover with foil and warm in a 350°F oven for 20 to 25 minutes, until the center reaches 165°F. The foil keeps the cornbread from drying out.

Frequently Asked Questions

Can I use raw chicken?
No. The casserole only bakes for about 30 minutes, which is not enough time to safely cook raw chicken under the topping. Cook it first so it reaches 165°F, or use rotisserie chicken.

Will one box of cornbread mix cover a 9×13 dish?
Yes, it makes a thin layer that bakes up golden and tender. If you like more cornbread, use two boxes, or bake it in an 8×8 dish for a thicker topping.

Why is my cornbread soggy on the bottom?
A little softness where it meets the filling is normal. If it is wet, the filling was too thin or the casserole needed more time. Bake until a toothpick comes out clean.

Can I make it without canned soup?
Yes. Melt 3 tablespoons butter, whisk in 3 tablespoons flour, then whisk in 1 1/2 cups chicken broth. Simmer until thick and use it in place of the soup and milk.
