Harvest Chicken and Stuffing Casserole

This harvest chicken and stuffing casserole tastes like the best plate of Thanksgiving leftovers, built on purpose. Creamy chicken with sage, Gruyère and tart-sweet cranberries sits under a buttery stuffing crust that bakes up crisp at the edges. A rotisserie chicken and a box of stuffing mix do the heavy lifting, so it fits on a weeknight.

What I like most is in the small details. The celery and onion get five minutes in a pan, so they’re tender instead of crunchy. Half the cranberries stay out of the oven so they don’t scorch. You’ll also find a real doneness temperature, make-ahead and freezing notes, and an honest look at the sodium, with ways to lower it.

Why You’ll Love This Recipe

The vegetables are soft. The filling only bakes for about half an hour, so raw celery never fully softens and raw onion keeps its bite. Five minutes in butter fixes both and adds a little sweetness.

The stuffing is ready when you need it. It needs a few minutes to soak up the hot broth, so I start it first. It goes on fluffy instead of soupy.

The cranberries stay bright. The ones in the filling plump up in the sauce. The ones scattered on at the end stay chewy and add color.

Ingredients You’ll Need

Makes one 9×13-inch (23×33 cm) casserole, 8 servings.

For the filling

1 tablespoon unsalted butter – For softening the celery and onion.

1/2 cup diced celery (about 1 large rib) – Cooked first, so it isn’t crunchy.

1/4 cup finely chopped yellow onion – Five minutes in the pan takes the bite out.

4 cups shredded rotisserie chicken – Most store-bought chickens give 3 to 4 cups of meat, so measure it and top up with leftover chicken if you need to.

1 can (10.5 ounces / 298 g) condensed cream of chicken soup – The base of the sauce.

1/2 cup sour cream – A little tang.

1/2 cup low-sodium chicken broth – It keeps the filling from going stiff.

3/4 cup dried cranberries – They plump up in the sauce.

1 cup shredded Gruyère or sharp white cheddar (4 ounces / 113 g) – I’d choose Gruyère if you can. More on that below.

1/2 teaspoon ground sage – It’s what makes this taste like Thanksgiving.

1/2 teaspoon poultry seasoning – It sits right next to the sage.

1/2 teaspoon black pepper – Just enough.

For the stuffing topping

1 box (6 ounces / 170 g) chicken or herb stuffing mix – Either one works.

1 1/2 cups low-sodium chicken broth – Heated until steaming, so the stuffing soaks it up.

1/4 cup (57 g) unsalted butter, melted – It makes the topping rich and golden.

To finish

1/4 cup dried cranberries – These go on after baking.

No added salt is needed. The soup, stuffing mix, chicken and cheese bring plenty.

How to Make This Recipe

Heat the oven to 375°F (190°C) and grease a 9×13-inch baking dish. Start with the stuffing. Heat the 1 1/2 cups of broth until steaming, either in the microwave or in a small pot. Pour it over the stuffing mix in a medium bowl, add the melted butter, and stir until every crumb is moistened. Set it aside while you make the filling.

Melt 1 tablespoon of butter in a skillet over medium heat. Cook the celery and onion, stirring now and then, for about 5 minutes, until the onion turns translucent and the celery bends without snapping. Take the pan off the heat.

In a large bowl, combine the chicken, soup, sour cream, the 1/2 cup of broth, the softened vegetables, 3/4 cup of cranberries, the cheese, sage, poultry seasoning and pepper. Stir until the chicken is evenly coated, then spread the mixture into the baking dish in an even layer.

Fluff the stuffing with a fork and spoon it over the filling in small clumps, covering the surface. Don’t press it down.

Bake uncovered for 30 to 35 minutes, until the edges bubble, the top is golden, and the center reads 165°F (74°C) on an instant-read thermometer. If the topping is browning faster than the center is heating, lay a loose sheet of foil over the dish. If your chicken went in straight from the fridge, expect closer to 40 minutes.

Let the casserole rest for 10 minutes, so the sauce thickens enough to scoop cleanly. Scatter the remaining 1/4 cup of cranberries over the top and serve.

My “Crisp Top, Creamy Middle” Mini Guide

• Spoon the stuffing on loosely. Packed down, it turns into a dense, soggy lid.
• Bake it uncovered, and top it right before it goes in. Covered, or assembled hours ahead, the topping goes soggy.
• Check the middle, not the top. If the top browns first, tent it with foil and bake until the center hits 165°F (74°C).
• If the filling looks thick or dry, add an extra 1/4 cup of broth. Lean, breast-heavy chicken soaks up more sauce.

Helpful Tips

Gruyère or Cheddar?

Gruyère melts smoothly into the sauce, and its nutty flavor sits naturally next to sage. Sharp white cheddar is the budget pick and gives a tangier filling. Either way, grate it from a block if you can. Pre-shredded cheese is coated with anti-caking starch and melts a little less smoothly.

Can You Make Chicken and Stuffing Casserole Ahead of Time?

Yes, with one rule: keep the topping separate. Assemble the filling in the baking dish, cover it and refrigerate for up to 24 hours. Add the stuffing topping right before baking, because overnight it soaks up moisture from the filling and bakes up soggy. Straight from the fridge, the dish needs about 10 to 15 extra minutes, so go by the 165°F (74°C) center temperature.

To freeze it, wrap the unbaked filling tightly, without the topping, for up to 3 months. Thaw it in the refrigerator overnight, add fresh stuffing and bake as above. The sauce can look slightly grainy after freezing, but stirring the thawed filling before you top it brings it back together.

Storing and Reheating Leftovers

Refrigerate leftovers within 2 hours of baking, and eat them within 3 to 4 days. Reheat portions in the microwave, or the whole dish covered with foil at 350°F (175°C) until hot in the center. Take the foil off for the last 5 to 10 minutes so the topping crisps again.

Sodium and Nutrition

Per serving (1/8 of the dish), approximate: 470 calories, 27 g protein, 36 g carbohydrates, 15 g sugars, 23 g fat and about 950 mg sodium as written. These are estimates from USDA FoodData Central and typical label values. Brands will shift them, and rotisserie chicken varies the most, since some stores brine their birds far more heavily than others.

Sodium is the number worth watching. With regular broth and salted butter, one serving climbs to roughly 1,150 mg, about half of the 2,300 mg daily limit in the U.S. Dietary Guidelines. The low-sodium broth and unsalted butter already cut about 200 mg. To go further, use a reduced-sodium condensed soup, or roast your own chicken.

Variations (and One to Skip)

• Apple and pecan: fold 1/2 cup of diced tart apple into the filling and scatter 1/3 cup of chopped pecans over the stuffing before baking.
• Cornbread stuffing: a 6 ounce box of cornbread stuffing mix gives a sweeter, crumblier topping.
• The one to skip, fresh cranberries: they’re far too tart without added sugar, and they burst in the oven, leaking juice that turns the filling pink and watery. Stick with dried.

What to Serve With It

It’s rich and creamy, so pair it with something sharp and green. Roasted green beans or Brussels sprouts with a squeeze of lemon cut through the sauce, and so does a bitter-leaf salad with a mustard vinaigrette. On a holiday, whole-berry cranberry sauce on the side echoes the cranberries in the filling.

Final Thoughts

This is a simple dinner, built from a rotisserie chicken and a box of stuffing. A few small steps do most of the work: softening the vegetables, keeping the topping loose, holding some cranberries back until the end.

It tastes like the part of Thanksgiving people go back to the table for, and it asks for an ordinary night’s worth of effort.
