Preheat your oven to 425°F (220°C).
Rinse the chicken inside and out, then pat it dry with paper towels.
Rub the olive oil all over the chicken, and season generously with kosher salt and freshly ground black pepper.
Stuff the cavity with the fresh herbs, smashed garlic cloves, and lemon halves.
Place the chicken on a roasting pan or baking dish, breast side up.
Roast in the preheated oven for 1 hour and 30 minutes, or until the juices run clear when you cut between a leg and thigh.
Remove the chicken from the oven and let it rest for 10-15 minutes before carving.
