Roast Chicken with Garlic and Thyme

Preheat oven to 450 degrees. Let chicken stand at room temperature for 30 minutes. Rub chicken all over with cut side of garlic. Season cavity with salt and pepper; stuff with garlic halves and thyme. Brush chicken with butter; generously season with salt and pepper. Transfer chicken to a rimmed baking sheet. Cross legs, and tie with kitchen twine.

Roast chicken, basting after 30 minutes, until skin is crisp and golden and an instant-read thermometer inserted into thickest part of thigh reaches 165, about 1 hour. Let stand for 10 minutes before carving. Garnish with thyme.
