To achieve crispy skin on a roast chicken, ensure the chicken is dry before roasting, use high heat initially, and baste with rendered fat during the cooking process.
Achieving perfectly crispy skin on a roast chicken involves several key steps. First, thoroughly dry the chicken, both inside and out, using paper towels. Moisture is the enemy of crispy skin. You can even let the chicken air-dry in the refrigerator, uncovered, for a few hours or overnight. This helps to remove excess moisture from the skin's surface.
Next, consider salting the chicken generously, both inside and out, at least an hour before roasting, or even better, the day before. Salt draws out moisture and helps to season the chicken.
Roast the chicken at a high temperature initially, around 450°F (232°C), for the first 15-20 minutes. This helps to render the fat under the skin and start the crisping process. Then, reduce the temperature to 350°F (175°C) for the remainder of the cooking time to ensure the chicken cooks through without burning the skin.
Basting the chicken with rendered fat, such as butter or the chicken's own drippings, every 20-30 minutes during the roasting process also contributes to crispy skin. The fat helps to conduct heat and further crisp the skin.
Finally, let the chicken rest for at least 15 minutes before carving. This allows the juices to redistribute, resulting in a more flavorful and moist bird.
Avoid overcrowding the roasting pan. Ensure there's enough space around the chicken for hot air to circulate, which is crucial for even cooking and crispy skin. If necessary, use a larger roasting pan or remove any vegetables that might be steaming the chicken instead of roasting it.
