This easy chicken zucchini casserole is a wholesome meal that comes together quickly! With tender chicken, fresh zucchini, and melted cheese, it’s comfort food at its best.
I love how it all bakes in one dish—fewer dishes to clean! Plus, my family enjoys it, and I don’t hear any complaints about veggies when cheese is involved! 😄
Key Ingredients & Substitutions
Zucchini: Fresh zucchini adds texture and nutrition. If you can’t find zucchini, summer squash works too. You can also try using cooked broccoli or spinach for a different flavor.
Cooked Chicken: Using leftover chicken is a great time-saver. If you don’t have chicken, rotisserie chicken or canned chicken can be handy alternatives. For a vegetarian option, consider using chickpeas or tofu.
Sour Cream & Mayonnaise: These provide creaminess. For a lighter option, Greek yogurt can replace sour cream. You can skip the mayo altogether if you prefer; the dish will still turn out tasty!
Cheese: Cheddar and mozzarella are my favorites for melting. Feel free to swap in your preferred cheese, like pepper jack for a kick or gouda for a smoky flavor.
How Can I Ensure My Casserole is Creamy and Flavorful?
The key to a creamy casserole lies in blending the ingredients properly. Make sure to sauté the onions and garlic first, as this adds extra flavor. When mixing, combine everything well so each bite is balanced.
- After mixing the chicken and veggies, taste and adjust seasoning. A bit more salt or pepper can really enhance flavors.
- Be careful not to overbake; keep an eye on the casserole to ensure the cheese doesn’t burn. You want it bubbly and golden!
Let it cool a few minutes after baking to help everything set up nicely, making it easier to serve.

How Much Time Will You Need?
This easy chicken zucchini casserole requires about 15 minutes of preparation time and 25-30 minutes of baking time. In total, you’re looking at around 45 minutes for a delicious, cheesy meal that everyone will love!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 375°F (190°C). This will ensure that your casserole cooks evenly and comes out perfectly bubbly and golden.
2. Sauté the Vegetables:
In a skillet, heat the olive oil or butter over medium heat. Add the finely chopped onion and minced garlic. Sauté for about 3-4 minutes until the onion is translucent and the garlic is fragrant. This will bring out their flavors!
3. Mix the Casserole Ingredients:
In a large mixing bowl, combine the shredded cooked chicken, sautéed onion and garlic, sour cream, mayonnaise, oregano, basil, salt, and pepper. Stir well until everything is mixed together.
4. Add the Zucchini:
Next, gently fold in the thinly sliced zucchinis into the chicken mixture until well combined. The zucchini will add a delicious freshness to the casserole!
5. Prepare for Baking:
Transfer the mixture into a greased baking dish. Spread it evenly to make sure it cooks uniformly.
6. Add the Cheese:
Sprinkle the shredded cheddar, mozzarella, and Parmesan cheeses evenly on top of the casserole. The cheese will create a yummy, gooey layer as it bakes!
7. Bake the Casserole:
Bake the casserole uncovered in the preheated oven for 25-30 minutes. It’s done when the casserole is bubbly and the cheese has melted and turned golden brown. Yum!
8. Cool and Garnish:
Once it’s done baking, remove the casserole from the oven and let it cool for about 5 minutes. This will help it set. Before serving, sprinkle freshly chopped parsley on top for a pop of color and freshness!
Enjoy your creamy, cheesy chicken zucchini casserole that’s quick to make and sure to please!
FAQ for Easy Chicken Zucchini Casserole
Can I Use Fresh or Frozen Zucchini?
Fresh zucchini is best for this recipe, as it will hold its texture better. If using frozen zucchini, be sure to thaw and drain it well to avoid excess moisture in your casserole.
How Long Can I Store Leftovers?
You can store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven until warmed through. Add a splash of cream or milk to maintain creaminess if needed!
Can I Make This Casserole Ahead of Time?
Yes! You can assemble the casserole a day in advance and keep it covered in the fridge. Just add a few extra minutes to the baking time if baking cold from the refrigerator. Enjoy a quick meal prep option!
What Can I Substitute for Mayonnaise?
If you want to lighten up the dish or avoid mayonnaise, Greek yogurt is a great alternative that adds creaminess and a bit of tang. You can also use additional sour cream for a similar texture.
