This Chicken Zucchini Casserole with Stuffing features rotisserie chicken, two kinds of squash, a creamy sauce, and a crunchy cheesy stuffing topping. It’s a delicious way to use up your garden produce and is a great option for Thanksgiving leftovers!
I love zucchini and I love growing it in my garden every year!
My family, on the other hand, does not love zucchini.
However, everyone loves this chicken zucchini casserole, even my husband, who normally shies away from recipes with zucchini in them.
This recipe works because it’s:
- So flavorful. The stuffing mix gives this recipe all of its delicious flavor. You’ll get a tasty recipe without having to use a ton of spices.
- A great recipe for excess zucchini. Those of use who grow zucchini know how hard it can be to use it all up before it goes bad. This is a yummy option.
- Easy to throw together! You won’t need to do any cooking for this casserole. Just mix everything together and dinner is underway.
This recipe was adapted from Six Sisters Stuff.
Step-by-Step Instructions
Preheat your oven to 350 degrees.
Combine 6 ounces of savory herb stuffing mix, 1/2 cup of melted butter, and 1 cup of shredded Parmesan cheese in a large mixing bowl. Remove 1 cup of the stuffing to use for the topping and set aside.
Add 4 cups of rotisserie chicken (or leftover turkey), 1 diced medium zucchini, 1 diced medium yellow squash, 10.5 ounces of cream of chicken soup, 1/2 cup of sour cream, and 1 teaspoon of onion powder to the large mixing bowl. Mix well.
Spread the chicken and zucchini mixture into a lightly greased 9×13 baking dish.
Top with the reserved stuffing mixture and bake uncovered for 40-50 minutes or until the squash is tender and the top is golden brown.

Yes, this casserole freezes well. Make the recipe in a disposable pan without baking it and cover with plastic wrap and foil to seal well. When you’re ready to eat it, you can leave it in your refrigerator to defrost or you can bake it frozen.
You’ll need to add more cooking time since the casserole is frozen. It will need to cook for 80-100 minutes at 350 degrees.

This casserole is not made for a slow cooker. The stuffing mix will get soggy and mushy and will not turn out well. Cooking it in the oven crisps the stuffing nicely so you get a variety of textures in each bite.
