Chicken and Zucchini Casserole is the kind of dinner that works especially well when you want something warm, creamy, and filling without spending the whole evening in the kitchen. Tender chicken, fresh zucchini, onion, and a creamy sauce are baked together under a buttery stuffing topping until the edges are bubbling and the top turns golden. The recipe is inspired by the classic creamy chicken-and-zucchini casserole style, with a few practical touches that make it easy to prepare at home.

How to Make Chicken and Zucchini Casserole
1. Prepare the baking dish
Preheat your oven to 350°F (175°C). Lightly grease a 9-by-13-inch baking dish so the casserole is easier to serve after baking.
2. Mix the stuffing topping
Add the stuffing mix to a large bowl and pour in the melted butter. Stir until the stuffing is evenly coated. Set aside about 1 cup of the mixture to use as the topping.
3. Make the chicken and zucchini filling
Add the sliced zucchini, diced onion, cooked chicken, cream of chicken soup, and sour cream to the remaining stuffing mixture. Stir everything together until the chicken and vegetables are evenly coated with the creamy mixture. Taste and add a little salt or black pepper if needed.
4. Assemble the casserole
Spread the chicken and zucchini mixture evenly into the prepared baking dish. Sprinkle the reserved buttery stuffing mixture over the top, making sure it is spread across the casserole rather than piled in one area.
5. Bake until golden
Bake for about 40–45 minutes, or until the casserole is hot and bubbling around the edges and the stuffing topping is golden brown. Let it rest for a few minutes before serving. This short resting time helps the creamy filling settle and makes it easier to scoop.

What You Can Do Better
A few small changes can make a noticeable difference in the finished casserole. Zucchini naturally contains a lot of water, so if your slices look particularly wet, pat them dry with paper towels before mixing them into the filling. This helps prevent an overly watery casserole.
For an easier weeknight version, use leftover cooked chicken or shredded rotisserie chicken. If you prefer more cheese, add a small handful of shredded cheddar or mozzarella over the filling before adding the stuffing topping. You can also replace part of the zucchini with yellow squash for a slightly different texture and color.
For extra flavor, season the chicken mixture with garlic powder, black pepper, or a small amount of dried herbs. Just remember that stuffing mix and canned soup can already contain quite a bit of seasoning, so taste before adding much salt.
Tips for the Best Chicken and Zucchini Casserole
- Use firm, fresh zucchini rather than very soft zucchini for a better texture.
- Pat excess moisture from the zucchini if it appears particularly watery.
- Rotisserie chicken is a convenient option when you do not want to cook chicken separately.
- Spread the stuffing topping evenly so you get some crisp topping in every serving.
- Allow the casserole to rest for a few minutes after removing it from the oven.
- For a cheesier version, add cheddar, mozzarella, or Parmesan before baking.
Serving Suggestions
This casserole is filling enough to serve as a complete dinner but a simple side can round out the meal. A fresh green salad, roasted carrots, steamed broccoli, or another roasted vegetable works well alongside the creamy casserole. If you want something more comforting, serve it with warm bread or dinner rolls to soak up the creamy sauce.

Storage and Reheating
Allow leftover casserole to cool before transferring it to an airtight container. Keep it refrigerated and use within about 4 days. Individual portions can be reheated in the microwave, while larger portions can be covered with foil and warmed in the oven.
For make-ahead preparation, assemble the casserole, cover it, and refrigerate it until you are ready to bake. If it goes into the oven directly from the refrigerator, it may need a little additional baking time.
Can You Freeze Chicken and Zucchini Casserole?
Yes. Let the baked casserole cool completely, then wrap it well and freeze it for up to about 2 months. Thaw it in the refrigerator before reheating for more even results. The stuffing topping may not be quite as crisp after freezing and reheating but the casserole will still make a convenient make-ahead meal.

Frequently Asked Questions
Can I use rotisserie chicken?
Yes. Shredded rotisserie chicken is one of the easiest shortcuts for this recipe. Remove the skin and bones, shred the meat, and use it in place of freshly cooked chicken breast.
How do I stop the casserole from becoming watery?
Excess moisture from zucchini is the main thing to watch. Pat the sliced zucchini dry before adding it to the filling, and avoid using zucchini that is very soft or watery.
Can I add cheese?
Absolutely. Cheddar, mozzarella, or Parmesan can be added to the filling or sprinkled over the top before the stuffing mixture is added.
Can I use yellow squash instead of some of the zucchini?
Yes. Yellow squash can replace part of the zucchini and works well in this type of casserole.
How long does Chicken and Zucchini Casserole last in the refrigerator?
Keep leftovers covered or stored in an airtight container in the refrigerator and use them within about 4 days.
Can I make this casserole ahead of time?
Yes. Assemble the casserole ahead of time, cover it, and refrigerate it until you are ready to bake. Allow a little extra baking time if the casserole is thoroughly chilled.
