Spatchcock means cutting out the backbone and flattening the chicken so it lies flat, roasting faster and more evenly than a whole chicken. Some butcher shops sell the chicken spatchcocked for you–if that’s the case, you can save a step. To plan out this recipe, brine the chicken a day before and soak the rice at least 2 hours or up to 24 hours before cooking. You can also make and refrigerate the brine a few days before brining the chicken.
