Ingredient Highlights

Every ingredient in this dish plays an important role in building flavor, texture, and nutrition. Together, they create a balanced and delicious meal with Mediterranean flair.

Chicken Breasts
Boneless, skinless chicken breasts are a lean, high-protein option that stay moist when baked over vegetables. You can also use boneless thighs if you prefer a richer flavor and softer texture.

Zucchini
This mild, tender vegetable adds moisture and volume to the dish without overpowering the other flavors. As it cooks, it becomes soft and buttery, absorbing the herbs and garlic beautifully. Yellow squash is a great alternative if zucchini isn’t available.

Sun-Dried Tomatoes
Sun-dried tomatoes bring a rich, tangy intensity that contrasts perfectly with the creaminess of the cheese and the mild vegetables. If you don’t have them on hand, chopped roasted red peppers or halved cherry tomatoes work well too.

Red Onion
Red onion turns soft and slightly sweet as it roasts, adding both color and depth of flavor. You can substitute white or yellow onion, but red adds a touch of sharpness that balances the dish.

Mozzarella Cheese
Mild and melty, mozzarella provides a creamy finish that ties everything together. You can also try combining it with a bit of feta, parmesan, or goat cheese to create new flavor layers.

Olive Oil
A drizzle of extra virgin olive oil enhances the taste of the vegetables and keeps everything from drying out while baking. It also supports even browning.

Garlic and Herbs
Garlic, oregano, basil, and thyme bring classic Mediterranean flavor to this dish. You can use dried herbs for convenience or fresh herbs for a brighter, more aromatic finish.

Optional additions like lemon zest, fresh parsley, olives, or chili flakes can bring even more flavor, depending on your taste.

How to Make It

1. Preheat and Prep
Set your oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish with olive oil to prevent sticking.

2. Prep the Vegetables
Slice 2 medium zucchinis and 1 red onion into thin rounds. Mince 3 garlic cloves and chop ½ cup of sun-dried tomatoes. Spread the zucchini, onion, garlic, and tomatoes in an even layer across the baking dish. Drizzle with 2 tablespoons of olive oil and gently toss everything to coat.

3. Season the Chicken
Pat dry 1.5 pounds of boneless, skinless chicken breasts. Season both sides generously with salt, pepper, 1 teaspoon of dried oregano, and 1 teaspoon of dried basil. Place the chicken directly on top of the vegetable mixture.

4. Add Cheese and Bake
Sprinkle 1 to 1½ cups of shredded mozzarella evenly over the top. Optionally, add a bit of dried thyme or chopped fresh herbs.

Cover the dish loosely with foil and place it in the oven. Bake for 25 minutes covered to help everything cook evenly.

5. Finish Uncovered
Remove the foil and return the dish to the oven. Bake for another 15–20 minutes, or until the chicken is cooked through and the cheese is bubbling and golden. The internal temperature of the chicken should reach 165°F.

6. Rest and Serve
Let the dish rest for about 5–7 minutes after baking. This allows the juices to redistribute and makes for cleaner servings.

Avoid These Pitfalls:

• Don’t skip drying the chicken—extra moisture can prevent browning.

• Overbaking can dry out the chicken; use a thermometer for accuracy.

• Avoid overcrowding—space the chicken and vegetables evenly to allow even roasting.
