Step 1

Preheat oven to 475 degrees. Place garlic in a medium bowl; cover with another same-size bowl, creating a dome. Hold bowls together tightly, and shake vigorously until skins are loosened, about 30 seconds. Remove and discard skins; set garlic aside.

Step 2

Place chicken in a large ovenproof skillet or roasting pan. Rub all over with 1 tablespoon butter; season with salt and pepper. Add thyme, garlic, and remaining tablespoon butter to skillet.

Step 3

Roast, basting occasionally with juices and stirring garlic, until an instant-read thermometer inserted in thickest part of a thigh (avoiding bone) registers 165 degrees, 45 to 60 minutes. Transfer to a platter, and let rest 10 minutes. Carve chicken, and serve with garlic and pan juices.
