Ingredients (Serves 6)

Gather these ingredients to create your Chicken Zucchini Bake. I’ve included notes on substitutions and tips to help you make the most of each component:

2 cups cooked, shredded chicken: Rotisserie chicken, leftover grilled chicken, or poached chicken breasts work perfectly. For a quick prep, shred a store-bought rotisserie chicken.
3 medium zucchinis, sliced into 1/4-inch rounds: Choose firm, medium-sized zucchinis for the best texture. Yellow squash or a mix of both can be used for variety.
1 cup cherry tomatoes, halved: These add a burst of sweetness and color. Grape tomatoes or diced Roma tomatoes are great alternatives.
1 cup shredded mozzarella cheese: Provides that gooey, stretchy texture. Low-moisture mozzarella melts best, but part-skim works for a lighter option.
1/2 cup grated Parmesan cheese: Adds a nutty, salty depth. Pecorino Romano can be used for a sharper flavor.
1/2 cup cream cheese, softened: Creates a creamy, rich layer. Neufchâtel cheese or Greek yogurt can be substituted for a lighter version.
1 teaspoon garlic powder: For a subtle, savory kick. Fresh minced garlic (2–3 cloves) can be used for a bolder flavor.
1 teaspoon Italian seasoning: A blend of herbs like oregano, basil, and thyme for that classic Italian flair. Make your own by mixing equal parts of these dried herbs.
Kosher salt and freshly ground black pepper: Season to taste to enhance all the flavors. Adjust at multiple stages for balance.
1 tablespoon olive oil: Helps the vegetables roast evenly and adds a touch of richness. Avocado oil or melted butter can be used instead.
Fresh basil, chopped (optional): A vibrant garnish that adds freshness. Fresh parsley or oregano can also be used for a different herbaceous note.

Equipment Needed

9×13-inch baking dish: A standard casserole dish is perfect for this recipe. A slightly smaller or larger dish can work, but adjust cooking time as needed.
Large mixing bowls: For tossing the vegetables and mixing the chicken-cheese mixture.
Cutting board and sharp knife: For slicing the zucchini and tomatoes.
Measuring cups and spoons: For precise ingredient amounts.
Aluminum foil: To cover the dish during baking, ensuring the zucchini cooks through without drying out.
Spatula or wooden spoon: For mixing and spreading the ingredients.

Instructions: Crafting Your Cheesy Masterpiece

Follow these step-by-step instructions to create a Chicken Zucchini Bake that’s as delicious as it is beautiful. I’ve included extra tips to ensure success and make the process enjoyable.

Step 1: Preheat and Prep the Oven
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray or a drizzle of olive oil to prevent sticking. This step ensures your casserole slides out easily for serving. If you prefer a crispier top, brush the dish with a bit of extra olive oil for added richness.

Step 2: Prepare the Vegetables
In a large mixing bowl, combine the sliced zucchinis and halved cherry tomatoes. Drizzle with 1 tablespoon of olive oil, then sprinkle with 1/2 teaspoon kosher salt, 1/4 teaspoon black pepper, and 1 teaspoon Italian seasoning. Toss everything together to ensure the vegetables are evenly coated. The oil and seasoning help the veggies roast to perfection, bringing out their natural sweetness. Set the bowl aside while you prepare the chicken mixture.

Step 3: Mix the Chicken and Cheese
In another large bowl, combine the 2 cups shredded chicken, 1/2 cup softened cream cheese, 1 cup shredded mozzarella cheese, 1/2 cup grated Parmesan cheese, and 1 teaspoon garlic powder. Use a spatula or wooden spoon to mix until everything is well blended. The cream cheese acts as a creamy binder, while the mozzarella and Parmesan create that irresistible cheesy texture. If the cream cheese is too firm, microwave it for 10–15 seconds to soften it further. Taste the mixture and add a pinch of salt or pepper if needed, depending on the seasoning of your cooked chicken.

Step 4: Assemble the Casserole
Spread half of the zucchini and tomato mixture in an even layer across the bottom of the prepared baking dish. This creates a vibrant, veggie-packed base. Next, spoon the chicken and cheese mixture over the vegetables, spreading it evenly with a spatula to cover the base layer. Top with the remaining zucchini and tomato mixture, arranging the slices attractively if you want a picture-perfect presentation. The layered approach ensures every bite has a balance of chicken, cheese, and vegetables.

Step 5: Bake to Perfection
Cover the baking dish tightly with aluminum foil to trap steam and help the zucchini cook through without drying out. Bake in the preheated oven for 25–30 minutes, until the vegetables are tender and the cheese is melted. Remove the foil and bake for an additional 10–15 minutes, until the top is golden brown and bubbly. If you love an extra crispy top, switch the oven to broil for the last 2–3 minutes, but watch closely to avoid burning.

Step 6: Garnish and Serve
Remove the casserole from the oven and let it cool for 5–10 minutes to set, making it easier to slice and serve. Sprinkle with fresh chopped basil (if using) for a burst of color and flavor. The basil adds a fresh, aromatic note that complements the cheesy richness. Serve warm, scooping generous portions onto plates, and enjoy the melty, comforting goodness of this Chicken Zucchini Bake!

Tips for Success

Prevent Soggy Zucchini: Zucchini releases water as it cooks. To reduce excess moisture, you can lightly salt the zucchini slices and let them sit for 10 minutes before patting dry with paper towels. This step is optional but helps achieve a firmer texture.
Use Leftover Chicken: This recipe is a great way to use up leftover chicken. Rotisserie chicken adds extra flavor, but grilled, baked, or poached chicken works just as well.
Cheese Variations: Swap mozzarella for cheddar or provolone for a different flavor profile. Add a sprinkle of feta or goat cheese for a tangy twist.
Add More Veggies: Incorporate sliced mushrooms, spinach, or diced bell peppers into the vegetable layer for extra nutrition and flavor.
Make It Spicy: Add a pinch of red pepper flakes or a dash of hot sauce to the chicken mixture for a subtle kick.
Storage and Reheating: Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the oven at 350°F (175°C) for 10–15 minutes or in the microwave until warmed through.
Freezing: Assemble the casserole but don’t bake it. Wrap tightly in plastic wrap and foil, then freeze for up to 2 months. Thaw in the refrigerator overnight and bake as directed, adding 5–10 minutes to the covered baking time.
Gluten-Free and Low-Carb: This recipe is naturally gluten-free and low-carb, making it suitable for many dietary needs. Double-check that your cheeses and seasonings are gluten-free if necessary.

Serving Suggestions

This Chicken Zucchini Bake is a complete meal on its own, but pairing it with the right sides can elevate the experience:

Salad: Serve with a crisp Caesar salad or a mixed green salad with a lemon vinaigrette to balance the richness.
Bread: Pair with garlic bread, dinner rolls, or a crusty baguette to soak up the cheesy juices.
Grains: For a heartier meal, serve alongside quinoa, wild rice, or cauliflower rice for a low-carb option.
Wine Pairing: A chilled glass of Sauvignon Blanc or Pinot Grigio complements the dish’s fresh and cheesy flavors. For a non-alcoholic option, try sparkling water with a splash of lemon.
