Ingredients You’ll Need
This recipe keeps things blissfully simple, letting vibrant veggies and a few pantry staples do all the heavy lifting on flavor and texture. Each item is carefully chosen to create that magic combo of color, taste, and melty goodness you want in a Chicken Zucchini Bake!
- 2 cups cooked shredded chicken: Rotisserie or leftover baked chicken both work perfectly for maximum juiciness and speedy prep.
- 2 medium zucchinis, sliced: Zucchini adds freshness, moisture, and that irresistible tender bite to every forkful.
- 1 cup cherry tomatoes, halved: The sweetness and burst of color balance out savory notes and brighten up the casserole.
- 1 cup mushrooms, sliced: Mushrooms infuse earthiness and soak up all those tasty seasonings beautifully.
- 1/2 cup red onion, thinly sliced: Red onion provides a hint of bite and a subtle caramelized flavor when baked.
- 1 teaspoon Italian seasoning: Just the right mix of herbs to instantly transport your tastebuds to the Mediterranean.
- 1/2 teaspoon garlic powder: This gives each bite a gentle aromatic kick—so much easier than mincing garlic.
- Salt and pepper to taste: Essential for dialing in those flavors perfectly.
- 1 cup shredded mozzarella cheese: Mozzarella melts to that stretchy, bubbling finish everyone craves on a bake.
- 1/4 cup grated Parmesan cheese: Adds salty, nutty depth and creates irresistible golden edges.
- 1 tablespoon olive oil: Helps the veggies roast up tender and juicy rather than drying out.
- Fresh basil or parsley, for garnish: A finishing sprinkle for bursts of color and zippy freshness.
How to Make Chicken Zucchini Bake
Step 1: Prep Your Oven and Dish
Start by preheating your oven to 375°F (190°C). While the oven heats up, grease a medium baking dish with a touch of olive oil or nonstick spray so nothing sticks. This is your blank canvas for all the layers of flavor ahead!
Step 2: Toss the Veggies
In a large bowl, add your sliced zucchini, halved cherry tomatoes, sliced mushrooms, and thinly sliced red onion. Drizzle with the olive oil, then sprinkle in the garlic powder, Italian seasoning, plus a good pinch of salt and pepper. Toss everything together until the veggies are nicely coated and shimmering—they’ll roast up perfectly this way.
Step 3: Add Chicken and Combine
Now it’s time for the heart of your Chicken Zucchini Bake! Pour the cooked shredded chicken into your well-seasoned veggie mixture. Mix until all the chicken and veggies are evenly combined so every bite gets an even party of flavors.
Step 4: Assemble in the Baking Dish
Transfer your chicken and veggie mix into the prepared baking dish. Spread it into an even layer so everything bakes up uniformly. Don’t worry if it looks a bit full—the veggies will shrink slightly and get perfectly tender in the oven.
Step 5: Cheese the Top
Sprinkle the mozzarella and Parmesan evenly over the top. The mozzarella creates tons of gooey stretch, while the Parmesan adds those golden brown spots and that classic savory finish you expect from a top notch Chicken Zucchini Bake.
Step 6: Bake and Finish
Put your dish into the oven and bake for 25 to 30 minutes. You’ll know it’s ready when the cheese is melted, bubbly, and dotted with golden brown spots. Let the Chicken Zucchini Bake cool just a bit, top with fresh basil or parsley, and serve it up warm. That cheesy goodness awaits!
How to Serve Chicken Zucchini Bake

Garnishes
Freshly torn basil or chopped parsley on top brightens up the whole bake and adds a pop of color and fresh-from-the-garden flavor. For even more flavor, try a light sprinkle of red pepper flakes or a squeeze of lemon juice right before serving—these little touches make the Chicken Zucchini Bake sing!
Side Dishes
This dish is hearty on its own, but it pairs beautifully with simple sides. A crisp green salad, roasted potatoes, or steamed green beans all complement the soft, cheesy comfort of the Chicken Zucchini Bake without overwhelming it. A crusty piece of whole-grain bread is also a fantastic way to soak up any extra juices!
Creative Ways to Present
You can spoon your Chicken Zucchini Bake into individual ramekins for a dinner-party-worthy presentation or serve family-style straight from the casserole dish for a cozy, communal feel. For lunch meal prep, portion it into containers with extra veggies or grains for a balanced, satisfying midday break.
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftover Chicken Zucchini Bake in an airtight container in the refrigerator. It will keep well for up to three days and makes a perfect ready-to-heat meal for busy nights or quick lunches.
Freezing
If you want to freeze portions, let the bake cool completely, then wrap tightly or use freezer-safe containers. Chicken Zucchini Bake holds up well in the freezer for up to 2 months—just thaw in the fridge overnight before reheating for best flavor and texture.
Reheating
To reheat, simply pop portions in the microwave for a couple of minutes, or warm the whole dish in a 350°F (175°C) oven until hot and bubbly again. If frozen, thaw first for even reheating—cover with foil in the oven to prevent the cheese from overbrowning.
FAQs
Can I use rotisserie chicken in Chicken Zucchini Bake?
Absolutely! Rotisserie chicken is a fantastic time-saver here, and it brings great flavor and juiciness to the Chicken Zucchini Bake. Just shred it and add as directed for easy prep.
How do I keep my zucchini from getting soggy?
Slice your zucchini evenly and don’t pile it too thick—this allows excess moisture to cook off as it bakes. A quick salt and pat dry can also help remove some of the water before tossing with the other veggies.
Is Chicken Zucchini Bake gluten-free?
Yes, this Chicken Zucchini Bake recipe is naturally gluten-free since it skips the breadcrumbs and flour. Just double check your cheese and any spice blends to confirm they’re certified gluten-free if needed.
Can I add other vegetables to the bake?
Totally! Feel free to swap in or add veggies like spinach, bell peppers, or squash. Just keep in mind that different veggies may release different amounts of water, so you might want to adjust bake time slightly.
How can I make this bake vegetarian?
Swap out the chicken for canned chickpeas, cooked lentils, or sautéed tofu for a vegetarian-friendly version. You’ll still get a protein-packed, hearty result with all the same cozy flavors!
