Creating Chicken Parmesan with Roasted Vegetables can be seamless by following these steps:

1. Preheat Your Oven: Start by preheating your oven to 400°F (200°C). This prepares it for both the chicken and the vegetables.

2. Prepare the Chicken: Season each chicken breast with salt, pepper, and Italian seasoning.

3. Set Up Breading Station: In one bowl, combine the breadcrumbs and Parmesan cheese. In another bowl, lightly beat an egg.

4. Coat the Chicken: Dip each chicken breast first into the egg, then coat it with the breadcrumb mixture, ensuring it’s well covered.

5. Bake the Chicken: Place the breaded chicken breasts on a baking sheet lined with parchment paper. Bake for 20-25 minutes, or until chicken is cooked through and the coating is golden brown.

6. Prep the Vegetables: While the chicken is baking, chop your vegetables into bite-sized pieces. Toss them with olive oil, salt, and pepper.

7. Roast the Vegetables: Spread the prepared vegetables on a separate baking sheet and roast them in the oven for 15-20 minutes until tender and slightly charred.

8. Add Sauce and Cheese: Once the chicken is done, remove it from the oven. Spoon marinara sauce over each piece, then sprinkle mozzarella cheese on top.

9. Final Bake: Return the chicken to the oven for an additional 5-10 minutes, until the cheese is melted and bubbly.

10. Garnish: Remove everything from the oven and let it cool slightly. Garnish with fresh basil before serving, if desired.

These steps will lead you to create a spectacular Chicken Parmesan with Roasted Vegetables that everyone will enjoy.
