Preheat your oven to 400°F (200°C).

Prepare your sheet pan by greasing it with olive oil or lining it with parchment paper.

In a mixing bowl, combine halved baby potatoes, broccoli florets, and sliced carrots. Toss with olive oil, garlic powder, oregano, paprika, salt, and pepper.

Spread the seasoned vegetables evenly across the prepared sheet pan.

Place the chicken breasts on the pan, drizzle with olive oil, and season with Parmesan, salt, and pepper.

Bake for 25-30 minutes, until chicken is cooked through and veggies are tender.

Let it cool slightly before serving.
