Simmer the chicken
60 minPlace the chicken in a large pot, add cold water, and bring it to a boil. Skim off the foam. Add half of the halved onion, salt, and black pepper, then lower the heat. Simmer gently for 55 minutes, until the surface barely trembles. Check the thickest part of the thigh near the bone; it must reach 74°C / 165°F. If it has not, cook for 10 minutes more.
