Step 1: Cook the Pasta

• Fill a large pot with water and bring it to a rolling boil.
• Add 1 teaspoon of salt and a splash of olive oil to the boiling water.
• Add the pasta and cook according to the package instructions until al dente.
• Drain the pasta and set it aside.

Step 2: Prepare the Chicken and Vegetables

• Heat 3 tablespoons of olive oil in a large skillet over medium heat.
• Add the chopped onion and sauté until translucent, about 3 minutes.
• Add the garlic and cook for another minute.
• Add the chicken pieces to the skillet and season with salt, pepper, oregano, and basil. Cook for 7-10 minutes until the chicken is fully cooked and browned.
• Toss in the chopped tomatoes and cook for another 5-7 minutes, stirring occasionally, until the tomatoes soften and form a sauce.

Step 3: Combine the Pasta and Sauce

• In a large mixing bowl, combine the cooked pasta and the chicken-tomato mixture.
• Stir well to ensure the pasta is evenly coated with the sauce.

Step 4: Assemble the Pasta Bake

• Grease a baking dish lightly with olive oil.
• Pour the pasta mixture into the baking dish and spread it evenly.
• Sprinkle the shredded mozzarella cheese and grated Parmesan cheese over the top.

Step 5: Bake

• Preheat your oven to 375°F (190°C).
• Place the baking dish in the oven and bake for 20-25 minutes, or until the cheese is melted, golden, and bubbly.

Step 6: Serve

• Remove the baked chicken pasta from the oven and let it cool for 5 minutes to allow the flavors to settle.
• Serve hot, garnished with fresh basil or parsley if desired.
