This Easy Chicken Zucchini Casserole is a comforting dish loaded with bits of juicy chicken, fresh zucchini, and cheesy goodness. It’s perfect for busy weeknights!
Plus, it’s a one-pan wonder, which means fewer dishes to wash. I love making it on those quiet evenings when I want something quick and tasty without the fuss.
Key Ingredients & Substitutions
Zucchini: Fresh zucchini is the star of this dish. If you can’t find it, yellow squash works well as a substitute. Both vegetables provide a nice texture and absorb flavors beautifully.
Chicken: I love using rotisserie chicken for its ease and flavor, but leftover chicken or even turkey can be used. For a vegetarian version, chickpeas or diced tofu can be a great alternative.
Cheese: Cheddar is my favorite choice for this casserole, but feel free to mix it up! Monterey Jack or mozzarella can also give a lovely meltiness. If you’re dairy-free, try a vegan cheese substitute.
Sour Cream: Sour cream contributes creaminess. Greek yogurt can be a healthier option. For a dairy-free version, try cashew cream or a plant-based yogurt.
How Do I Make Sure My Casserole is Creamy and Tasty?
Getting the right texture and flavor in your casserole requires a few careful steps. Here’s how to ensure you get it just right:
- Start by sautéing the onion and garlic; this will enhance the flavors. Don’t rush this step; let them soften before adding them to the chicken mixture.
- Mix the wet ingredients (sour cream, mayonnaise) thoroughly with the chicken and seasonings to create a creamy base that holds everything together.
- Fold in the zucchini gently to prevent them from breaking down. This helps keep some structure in the dish after baking.
- Make sure not to overbake it; once it’s bubbly and golden on top, it’s done! A little resting time after baking will help everything settle before you serve.

How Much Time Will You Need?
This Easy Chicken Zucchini Casserole takes about 15-20 minutes to prepare and 25-30 minutes to bake, giving you a total time of about 50 minutes from start to finish. It’s a quick, hearty meal that is perfect for any day of the week!
Step-by-Step Instructions:
1. Preheat the Oven:
Begin by preheating your oven to 375°F (190°C). While it’s heating, lightly grease a medium casserole dish with cooking spray or olive oil to prevent sticking.
2. Sauté the Onion and Garlic:
In a skillet, heat the olive oil over medium heat. Add in the finely chopped onion and minced garlic. Sauté them for about 3-4 minutes until the onion looks translucent and the garlic smells fragrant. This step really brings out the flavor!
3. Mix the Ingredients:
In a large mixing bowl, combine the cooked chicken, sautéed onion and garlic, sour cream, mayonnaise, Italian seasoning, salt, and pepper. Stir everything together until it’s mixed well and creamy.
4. Add Zucchini and Cheese:
Gently fold the sliced zucchini and half of the shredded cheddar cheese into the chicken mixture. Make sure everything is coated well without breaking the zucchini slices.
5. Prepare for Baking:
Transfer the mixture into the greased casserole dish, spreading it out evenly. Sprinkle the remaining cheddar cheese and the grated Parmesan cheese on top to create a cheesy crust.
6. Bake the Casserole:
Place the casserole in the preheated oven and bake uncovered for 25-30 minutes. You’re looking for it to be bubbly and the cheese to have a lovely golden color.
7. Cool and Serve:
Once it’s done, remove the casserole from the oven and let it cool for about 5 minutes. This settling time allows for easier serving. You can garnish with chopped fresh parsley or basil before serving for a pop of color and flavor.
Enjoy your comforting, cheesy chicken zucchini casserole! It’s sure to be a hit at the dinner table!
FAQs for Easy Chicken Zucchini Casserole
Can I Use Fresh Zucchini Instead of Frozen?
Absolutely! Fresh zucchini is ideal for this casserole as it retains its texture and moisture. Just make sure to slice it into thin rounds, which helps it cook evenly.
Can I Substitute the Mayonnaise?
Yes! If you prefer to avoid mayonnaise, you can use additional sour cream or Greek yogurt instead. You could also try using cream cheese for a richer texture.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm it in the oven or microwave until heated through. If it seems dry, add a splash of broth or water before reheating.
Can I Make This Casserole Ahead of Time?
Yes, you can prepare the casserole up to the baking step and then cover it and refrigerate for up to 24 hours. When ready to bake, just pop it in the oven; you may need to add a few extra minutes to the baking time if it’s coming straight from the fridge.
