Chicken Zucchini Casserole
When you’re craving something comforting but still want to keep it on the lighter side, Chicken Zucchini Casserole is the perfect answer. It brings together tender chunks of seasoned chicken, layers of soft zucchini, and a creamy, cheesy filling that feels indulgent without going overboard. Every bite gives you warmth and satisfaction, like a weeknight dinner you’ll want to repeat.
This casserole doesn’t just taste amazing, it’s also a great way to sneak more veggies into your family’s meals. Zucchini pairs so well with the flavors of garlic, herbs, and creamy cheese that even the pickiest eaters will be asking for seconds. Plus, it reheats beautifully, making it a smart option for meal prepping.
Why You’ll Love This Chicken Zucchini Casserole
It’s hearty yet not too heavy, which makes it a balanced dish you can enjoy year-round. Whether you’re trying to use up extra garden zucchini or looking for a make-ahead dinner option, this casserole covers all the bases. The flavors meld perfectly, the textures are satisfying, and it can easily be made gluten-free or keto-friendly.
What Kind of Chicken Should I Use?
You can use either cooked shredded chicken breast or thighs for this recipe. Rotisserie chicken is a great shortcut and adds a little extra flavor. If you have raw chicken on hand, quickly pan-cooking it with a bit of seasoning works just as well. What matters most is that the chicken is juicy and well-seasoned before layering it into the casserole.
Ingredients for the Chicken Zucchini Casserole
To build a casserole that’s creamy, flavorful, and just the right amount of cheesy, here are the essentials you’ll need. Each ingredient plays a role in making the dish comforting and crave-worthy.
Zucchini adds bulk and moisture while keeping the dish light. Choose medium-sized ones for the best texture.
Chicken provides the hearty protein. Use shredded or diced, cooked chicken.
Sour Cream brings creaminess and tang that balances the savory flavors.
Cheddar Cheese melts into a gooey topping and adds sharpness.
Parmesan Cheese adds depth and a salty bite that complements the zucchini.
Eggs help bind everything together into a cohesive bake.
Garlic Powder and Onion Powder add rich flavor without extra moisture.
Salt and Pepper to bring all the ingredients into harmony.

How To Make the Chicken Zucchini Casserole
Step 1: Prepare the Zucchini
Slice the zucchini thin and spread it out on paper towels. Sprinkle lightly with salt and let it sit for 10 minutes to draw out moisture. Pat dry to prevent a watery casserole.
Step 2: Mix the Filling
In a large bowl, combine the cooked chicken, sour cream, cheeses, eggs, and seasonings. Stir until everything is well incorporated.
Step 3: Layer the Ingredients
In a greased baking dish, layer zucchini slices, followed by the chicken mixture. Repeat the layers until everything is used up, ending with a generous sprinkle of cheese.
Step 4: Bake to Perfection
Bake at 375°F for about 30 to 35 minutes or until bubbly and golden on top. Let it rest for 5 to 10 minutes before serving so the layers set nicely.
How to Serve and Store Chicken Zucchini Casserole
This casserole serves around 6 people comfortably, making it ideal for a family dinner or casual gathering. It plates beautifully with a simple side salad or warm bread. Leftovers should be stored in an airtight container in the fridge and will keep well for up to 4 days.
