Remove any giblets from inside the chicken and discard. Wash your hands and any surfaces that touched the raw chicken.
Pat the chicken dry inside and out with paper towels. Do not rinse under running water.
Tie the legs together with kitchen string (truss) if desired so the chicken cooks more evenly.
Place the chicken breast-side up on a rack in a roasting pan (or directly in the pan). If you prefer easier cleanup, you can line the pan or loosely cover it with foil.
Let the chicken sit at room temperature 20–30 minutes while you preheat the oven. Preheat the oven to 450°F (230°C).
Roast the chicken for 15 minutes per pound. For a 5‑pound chicken this is about 75 minutes.
Check doneness with an instant-read meat thermometer inserted into the thickest part of the thigh without touching bone; the internal temperature should read 165°F (74°C). If it hasn’t reached 165°F, continue roasting and recheck every 5–10 minutes.
Remove the chicken from the oven and let it rest 10 minutes before carving and serving.
