Chicken Broccoli Stuffing Casserole is a rich, cheesy comfort dish that’s both easy to prepare and satisfying. Perfect for holiday gatherings or a quick weeknight dinner, every bite is loaded with wholesome chicken, fresh broccoli, cheddar cheese, and mouthwatering stuffing.

I may have gone a little overboard with the boxed stuffing mix this year. Initially, I bought a couple boxes to make a meatloaf and a stuffing bake for our other site.

Then, I got more boxes for our apple cranberry walnut stuffing and chicken and stuffing casserole. It seems like there were a couple of other recipes in there somewhere, but I can’t think of think right this second. You get the picture though, right?

Somewhere in all of that I decided to make John a chicken and broccoli casserole and used stuffing as the topping. And, he loved it, so I’m making it for y’all, too!

It’s made with rotisserie chicken (super easy!), broccoli florets, shredded cheddar cheese, seasoned boxed stuffing mix, and a couple of other simple ingredients. This chicken casserole makes a great dish to serve alongside a Thanksgiving turkey or on a busy weeknight.

If you love a creamy, comforting chicken dinner that practically makes itself, my slow cooker creamy chicken pasta is another weeknight favorite worth adding to your rotation. For a casserole with a little Tex-Mex flair, my poblano chile relleno casserole is just as easy to throw together and always gets rave reviews at the dinner table.

Storage

Refrigerator: Store any leftover casserole in an airtight container in the refrigerator. The casserole will keep for up to 4 days.

Freeze: Let the baked casserole cool completely, then wrap tightly in plastic wrap followed a layer or two of aluminum foil. Freeze for up to 2 months.

Thawing and Reheating: Thaw the casserole in the fridge then heat in the oven on 350°F until warmed through. Warm individual servings in the microwave on half power until heated to the desired temperature.

Tips

Blanch or steam the broccoli. I actually prefer fresh broccoli in this casserole. Just steam or blanch it until it’s barely fork-tender before adding it. You don’t want it fully soft going in because it’ll continue to cook in the oven. If you go the frozen route, thaw it completely and squeeze out as much moisture as you can before adding it. Extra water in the filling will make the casserole soggy, and nobody wants that.
Cream Soup. Use any variety of condensed cream soup you have on hand or make homemade cream of chicken soup. Some tasty options are cream of mushroom, cheddar cheese soup, and cream of celery.
Make it lower sodium. Several of the ingredients in this recipe have a fair amount of sodium. Here are some tips on how to reduce it:
- Use low-sodium broth.
- Make homemade chicken instead of using rotisserie chicken.
- Purchase low-sodium stuffing mix.
- Use low-sodium or no sodium added soup, or make your own.
- Reduce the cheese to 1/2 cup.
Chicken thighs work too. If your family prefers dark meat, boneless skinless chicken thighs are a great swap for the rotisserie chicken. Just shred or chop them the same way.

Can I double this recipe?

Yes, this recipe easily doubles, but you’ll want to divide it between two separate pans or use a 9×13-inch if you’ve originally used a 9×9-inch dish.

Can chicken broccoli stuffing casserole be made in advance?

Yes, it can! My personal preference is to make the filling, cover it tightly so the plastic wrap is touching the filling, and refrigerate it overnight. Then, the following day add the stuffing and bake!

You can also completely assemble the chicken casserole, wrap it tightly to prevent the stuffing from drying out, and refrigerate overnight. Bake it the following day as written in the instructions.
