Put the chicken on a rimmed baking sheet and rub any remaining butter over the skin. Season each breast with just a pinch of freshly ground black pepper.
05Roast the chicken breasts, skin sides up, in the center of the oven until skin is crisped and chicken is cooked through, about 35 to 40 minutes. An instant-read thermometer should register 165 degrees F when inserted into the thickest part of the meat. Remove from the oven to a serving platter. Let stand 10 minutes before serving.06Cook's Note: This recipe makes 2 logs of compound butter; unused butter can be used to top grilled meats, burgers, or baked or mashed potatoes.
