This creamy chicken zucchini bake has rescued weeknight dinners at my house so many times. You get juicy chicken tucked under golden cheese with bursts of tomato and ribbons of tender zucchini. One baking dish does it all and dinner is on the table with hardly any prep.
I first served this when I needed something cozy and healthy last minute. My husband asked for seconds and even my picky eater cleared her plate.
Ingredients
- Shredded cooked chicken: This is the main protein for staying power. Use rotisserie chicken for convenience or leftover grilled chicken for extra flavor.
- Medium zucchinis: Bring a mild sweetness and lots of moisture. Look for small to medium size with unblemished skin for best taste.
- Cherry tomatoes: Give the bake juicy pops of brightness. Choose tomatoes that are firm and deep red for the best flavor.
- Shredded mozzarella cheese: Melts into a creamy blanket across the top. Always pick cheese you can shred yourself when possible for extra melt factor.
- Grated Parmesan cheese: Adds salty complexity and helps that bubbly golden topping. Parmigiano Reggiano is always worthwhile when you can find it.
- Softened cream cheese: This is your secret weapon for creamy texture throughout. Make sure it is at room temperature so it mixes evenly into the filling.
- Garlic powder: Enhances all the savory notes. Go for fresh smelling powder for the brightest flavor.
- Italian seasoning: Provides herby complexity. Pick blends with visible herbs and no fillers.
- Salt and pepper: These two bring out all the best flavors. Use kosher salt and freshly cracked black pepper if you have them.
- Olive oil: Keeps the bake from sticking and adds a finishing gloss. Quality extra virgin olive oil gives a floral and peppery note.
- Fresh basil: Optional but brings a refreshingly fragrant finish. Snip just before serving for best results.
Instructions
- Preheat the Oven:
- Set your oven to three seventy five degrees Fahrenheit or one ninety Celsius. This ensures the dish heats evenly and the cheese gets crisp edges.
- Mix the Filling:
- Combine shredded chicken, sliced zucchini, halved cherry tomatoes, mozzarella, cream cheese, garlic powder, Italian seasoning, salt, and pepper in a large mixing bowl. Mix until everything looks well distributed and coated with the cream cheese.
- Prepare the Baking Dish:
- Drizzle olive oil into your nine by thirteen inch dish. Then use your hands or a brush to cover the whole bottom and sides. This prevents sticking and adds subtle flavor.
- Add the Casserole Mixture:
- Spoon your chicken and vegetable blend into the dish. Spread everything into an even layer so it cooks consistently.
- Add the Parmesan Topping:
- Sprinkle grated Parmesan across the top. You want even coverage for the best golden result.
- Bake to Perfection:
- Slide the pan into your oven. Bake for twenty five to thirty minutes. The zucchini should become fork tender, the cheese will bubble, and the top will develop a rich golden crust.
- Cool and Garnish:
- Remove from the oven and let it cool for a few minutes before scooping portions. Top with torn fresh basil for an herby lift if desired.

The sweet snap of zucchini is my favorite part since it soaks up all those cheesy savory juices. Last time I made this my little one enthusiastically helped arrange the tomatoes and it made dinner feel special.
Storage Tips
Store leftovers in an airtight container and refrigerate for up to three days. You can reheat portions in the microwave or oven. The bake also tolerates freezing — wrap tightly and defrost before reheating on busy nights.
Ingredient Substitutions
You can swap the mozzarella for Monterey Jack or provolone for a twist. Greek yogurt works instead of cream cheese for extra tang and less richness. If tomatoes are scarce, diced red bell pepper fits right in.
Serving Suggestions
Serve this bake with a crisp green salad or some crusty bread. Warming up a portion for lunch the next day makes it easy to eat well. If you want more heartiness, stir in cooked brown rice or quinoa before baking.
Cultural and Historical Context
Baked dishes like this are loved in Mediterranean kitchens where chicken, vegetables, and cheese are everyday ingredients. Casseroles have also been staples of American family dinners since the mid century for their ability to stretch ingredients and feed a crowd.

This dish is a staple for busy weeknights and always brings comfort to the table. Each bite feels nourishing and the leftovers are just as good the next day.
