Place the whole chicken in a large heavy-bottomed stockpot, followed by the carrots, onion, celery, parsley, bay leaves and black peppercorns. Cover with water and bring to a boil.
Reduce the heat, partially cover with a lid, and simmer on low heat for 2 hours. Whilst the broth simmers, skim the top with a slotted spoon or fine-mesh strainer to remove the fat in excess.
Once ready, remove the chicken from the stockpot, then strain the broth through a fine-mesh strainer.
Serve the prepared brodo di pollo immediately on its own, with pastina or tortellini, or use it to flavor other recipes. Alternatively, cool it completely, refrigerate overnight, and the next day, remove the fat layer from the top before reheating.
