Ingredients
  

  • Main Ingredients
  • 2 boneless skinless chicken breasts, cut into bite-sized pieces
  • 2 medium zucchinis sliced into half-moons
  • 1 cup cherry tomatoes halved
  • ½ red onion thinly sliced
  • 2 cloves garlic minced
  • Seasoning & Oil
  • 2 tablespoons olive oil
  • 1 teaspoon dried oregano
  • ½ teaspoon dried basil
  • ½ teaspoon smoked paprika
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • ¼ teaspoon red pepper flakes optional, for heat
  • Cheese & Garnish
  • ½ cup shredded mozzarella or feta for a Mediterranean twist
  • ¼ cup grated Parmesan cheese
  • 2 tablespoons fresh parsley chopped

Equipment

  • 9×13-inch baking dish
  • Mixing bowl
  • Knife and cutting board

Method
 

  1. Preheat and prepare. Set your oven to 375°F (190°C). Lightly grease a baking dish with olive oil to prevent sticking.
  2. Combine the ingredients. In a large bowl, add the chicken pieces, zucchini, tomatoes, onion, and garlic. Drizzle with olive oil and sprinkle in all the seasonings (oregano, basil, paprika, salt, pepper, and red pepper flakes if using). Toss everything together until evenly coated.
  3. Assemble the dish. Transfer the mixture into the prepared baking dish. Spread it out into an even layer so everything cooks uniformly.
  4. Add the cheese. Sprinkle mozzarella and Parmesan evenly over the top, creating a layer that will melt and turn golden during baking.
  5. Bake covered. Cover the dish loosely with foil and place it in the oven. Bake for 20 minutes to allow the chicken to cook through and the vegetables to soften.
  6. Finish uncovered. Remove the foil and continue baking for an additional 10–15 minutes, until the cheese is melted and lightly golden the chicken is fully cooked (internal temperature of 165°F / 75°C)
  7. Garnish and serve. Remove from the oven and let the dish rest briefly. Sprinkle fresh parsley over the top before serving.
