Creating this Chicken Parmesan with Roasted Vegetables is easy when you follow these steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Chicken: Season the chicken breasts with salt, pepper, and Italian seasoning.
3. Bread the Chicken: Dip each chicken breast into breadcrumbs until fully coated. Set aside on a plate.
4. Roast the Vegetables:
– In a mixing bowl, combine the zucchini, bell peppers, onion, and garlic with olive oil, salt, and pepper.
– Spread the vegetable mixture onto a large baking sheet lined with parchment paper.
5. Bake the Vegetables: Place the vegetables in the preheated oven and roast for about 15-20 minutes, or until tender and lightly browned.
6. Cook the Chicken: While the vegetables are roasting, heat a large skillet over medium-high heat and add a drizzle of oil. Cook the breaded chicken for 3-4 minutes on each side until golden, then remove from heat.
7. Assemble the Dish: In a baking dish, pour a thin layer of marinara sauce. Place the browned chicken on top, then cover each piece with marinara sauce. Sprinkle mozzarella and Parmesan cheese over the top.
8. Bake the Chicken: Place the baking dish in the oven with vegetables and bake for 15-20 minutes until the cheese is melted and bubbly.
9. Finish Roasting the Vegetables: Check the vegetables and give them a stir halfway through the cooking time to ensure even roasting.
10. Serve Immediately: Once the chicken is fully cooked and the cheese is bubbly, remove from the oven and let rest for a few minutes before serving.
