Set your oven to 375°F.
Toss the potatoes, carrots, garlic, and onion with olive oil, salt, and pepper. Spread them out on a large rimmed baking sheet.
Pat the chicken dry with paper towels. Rub it all over with olive oil, then coat with the sun-dried tomato pesto. Season generously with salt, pepper, and herbs.
Set up the magic:
Place the baking sheet with vegetables on the lower rack of your oven.
Place the chicken directly on the oven rack above it.
Roast for about 1 hour 15 minutes to 1 hour 30 minutes, or until: The skin is golden and crispy
The internal temp reaches 165°F (74°C) and the juices run clear
Let the chicken rest for 10 minutes before carving. Serve with the flavour-packed vegetables underneath.
