Creating the Parmesan Crusted Chicken Sheet Pan Dinner is simple. Follow these steps to achieve a delicious meal:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Sheet Pan: Line a large sheet pan with parchment paper for easy cleanup.
3. Season the Chicken: In a bowl, mix together the Parmesan cheese, garlic powder, onion powder, Italian seasoning, salt, and black pepper.
4. Coat the Chicken: Dip each chicken breast into the Parmesan mixture, pressing lightly to ensure it sticks well.
5. Arrange on the Pan: Place the coated chicken breasts on one side of the prepared sheet pan.
6. Prepare the Vegetables: In a separate bowl, toss the broccoli and baby carrots with olive oil, salt, and pepper until evenly coated.
7. Add Vegetables to the Pan: Spread the seasoned vegetables on the other side of the sheet pan, ensuring they are in a single layer.
8. Bake: Place the sheet pan in the preheated oven and bake for 25-30 minutes, or until the chicken is cooked through and the vegetables are tender.
9. Broil for Extra Crispiness: If desired, switch to broil for the last 2-3 minutes to achieve a golden, crispy crust on the chicken.
10. Garnish and Serve: Remove from the oven, garnish with fresh parsley if using, and serve hot.

These straightforward steps will guide you in creating this incredible sheet pan dinner with ease.
