Ingredients

3 medium zucchinis, sliced into rounds
2 tablespoons olive oil
3 cloves garlic, minced
1 teaspoon Italian seasoning
½ teaspoon paprika
½ teaspoon salt
½ teaspoon black pepper
½ cup grated Parmesan cheese
1 cup shredded mozzarella cheese
1 small onion, finely chopped
½ cup cherry tomatoes, halved (optional)
Fresh parsley or basil for garnish

Instructions

Preheat your oven to 400°F (200°C).
Lightly grease a large baking dish or casserole dish with olive oil.
Slice the zucchini into thin rounds and cut the chicken into bite-sized cubes.
In a large bowl, combine chicken, zucchini, olive oil, garlic, onion, Italian seasoning, paprika, salt, and pepper. Mix well until everything is evenly coated.
Transfer the mixture into the prepared baking dish and spread it evenly.
Sprinkle Parmesan cheese evenly over the top, then add shredded mozzarella cheese.
Bake uncovered for 25–30 minutes, or until the chicken is fully cooked and the cheese is melted and golden.

Remove from the oven and let it rest for 5 minutes before serving.
Garnish with fresh parsley or basil and serve warm.

Tips for the Best Chicken Zucchini Bake

Use Fresh Zucchini:
Fresh zucchini works best because it holds its texture during baking and doesn’t become too soft.

Don’t Slice Zucchini Too Thin:
If the slices are too thin, they may become watery. Medium-thick slices work best.

Drain Excess Water:
Zucchini contains a lot of water. If your zucchini is very watery, lightly salt it and let it sit for 10 minutes, then pat dry.

Use Chicken Thighs for More Flavor:
Chicken breasts are lean, but chicken thighs are juicier and more flavorful.

Add Cheese at the Right Time:
If your cheese browns too quickly, add it during the last 10 minutes of baking.

Variations

This healthy chicken zucchini casserole is very flexible, and you can easily change it depending on what you have at home.
