Combine the olive oil, balsamic vinegar, cider vinegar, garlic, garlic powder, onion, powder, salt, pepper, and fresh basil. Marinate the chicken thighs in this mixture for at least half an hour.
Preheat the oven to 400.
Grease two large baking sheets. Arrange the chicken, potatoes, and vegetables on the sheet with as little overlap as possible.
Sprinkle additional salt, onion powder, and garlic powder on the potatoes and vegetables.
Cook about 40 minutes or until chicken is completely done and potatoes are slightly brown on top.
