This hearty Chicken Zucchini Bake has become my go-to solution for transforming simple ingredients into a comforting family meal that satisfies everyone at the table while keeping dinner nutritious and fuss-free.
I first created this dish during a particularly busy week when I needed something that could stretch our leftover rotisserie chicken into something special. The combination was such a hit that my husband now specifically requests my "cheesy zucchini thing" whenever summer squash is abundant in our garden.
Ingredients
- Cooked chicken: Two cups shredded provides the perfect protein base and means you can use rotisserie chicken or meal prep leftovers
- Medium zucchinis: Three fresh ones deliver moisture nutrient density and a mild flavor that takes on the seasonings beautifully
- Cherry tomatoes: One cup halved adds bright pops of color acidity and natural sweetness
- Mozzarella cheese: One cup creates that irresistible melty stretchy texture everyone loves
- Parmesan cheese: Half cup brings sharp nutty depth that elevates the entire dish
- Cream cheese: Half cup softened creates the creamy binding sauce without needing a separate roux
- Garlic powder: One teaspoon infuses aromatic flavor throughout without the work of mincing fresh garlic
- Italian seasoning: One teaspoon delivers complex herbal notes with just one ingredient
- Olive oil: One tablespoon prevents sticking and adds richness
- Fresh basil: Optional but highly recommended for that finishing bright herbaceous note

How To Make Chicken Zucchini Bake
- Preheat the Oven:
- Set your oven to 375°F and allow it to fully preheat while you prepare the ingredients. This temperature is perfect for cooking the zucchini through while creating a golden cheesy top.
- Create the Mixture:
- Combine all ingredients except the Parmesan and olive oil in a large mixing bowl. Use clean hands or a sturdy spoon to thoroughly incorporate everything ensuring the cream cheese is evenly distributed throughout. The mixture should look cohesive with the seasonings visible throughout.
- Prepare the Baking Dish:
- Coat a 9x13 inch baking dish with the olive oil making sure to cover the bottom and slightly up the sides. This prevents sticking and helps create a lightly crisp edge on your casserole.
- Assemble the Casserole:
- Transfer your chicken zucchini mixture to the prepared baking dish spreading it in an even layer. Press down slightly to eliminate air pockets which could cause uneven cooking.
- Add the Final Cheese Layer:
- Sprinkle the Parmesan cheese evenly across the top creating a blanket that will transform into a golden crust during baking.
- Bake to Perfection:
- Place in your preheated oven and bake for 25-30 minutes watching for the telltale signs of doneness zucchini that yields easily to a fork cheese that bubbles around the edges and a beautiful golden top.
- Rest Before Serving:
- Allow the casserole to rest for 5-7 minutes after removing from the oven. This crucial step lets the juices redistribute and helps maintain the structure when serving.

My absolute favorite part of this recipe is how the cream cheese melts into a velvety sauce that coats every bite. My grandmother always said the secret to a memorable casserole was finding the perfect binding ingredient and after trying countless versions I discovered cream cheese creates that homey comfort food quality that makes people feel cared for when they eat it.
Make It Your Own
This casserole welcomes customization based on your familys preferences or what ingredients you have on hand. For a Mediterranean twist add chopped kalamata olives crumbled feta and fresh lemon zest. The briny olives create a wonderful contrast against the creamy base.
If your household enjoys Tex-Mex flavors replace the mozzarella with a Mexican cheese blend and add black beans corn kernels and taco seasoning. The beans add hearty texture while the corn provides sweet pops throughout the dish.
Garden enthusiasts can incorporate additional vegetables like bell peppers mushrooms and red onion for extra color nutrition and flavor complexity. I find this variation particularly wonderful in late summer when gardens are overflowing with produce.

Dealing With Watery Zucchini
The biggest challenge when cooking with zucchini is managing its high water content. To prevent a soggy casserole consider salting your sliced zucchini and letting it sit in a colander for 10 minutes before patting dry with paper towels. This draws out excess moisture before baking.
Another effective technique is to slice your zucchini consistently at about 1/4 inch thickness. Pieces that are too thin disappear into the casserole while thicker cuts may remain firm when everything else is done cooking.
If you notice your casserole still has excess liquid after baking let it rest longer before serving or serve with a slotted spoon leaving the liquid behind in the baking dish.
Serving Suggestions
This versatile dish works beautifully on its own but can be paired with complementary sides for a more substantial meal. A simple green salad dressed with lemon vinaigrette creates a refreshing contrast to the rich casserole.
For those not watching carbs consider serving over cooked orzo pasta or with crusty garlic bread for soaking up the delicious sauce. The starchy accompaniments help balance the protein and vegetable focused casserole.
For special occasions transform this everyday casserole into a memorable spread by adding a platter of roasted vegetables a basket of warm dinner rolls and perhaps a light fruit dessert to follow.
