Watch and learn how to butterfly, or spatchcock, a chicken. Butterflying a chicken is a great technique for grilling or oven-roasting as it will cook faster and more evenly. Begin by patting your chicken dry. Turn over the chicken so its back is facing up. Using poultry or kitchen shears, cut along either side of the spine and remove it. Lay the chicken flat and use a knife to make a notch in the white cartilage in the breast bone at the neck end. Cut a slit on either side of the cartilage. Pop out the breast bone and remove it entirely. Turn over the chicken and tuck the wings under to keep it neat. You're now ready to cook your chicken.
