Pre-heat the oven to 200º C.
Heat half of the olive oil in a large cast iron gratin dish or frying pan over a moderate heat until hot. Season the pieces of chicken then sear until golden-brown in colour all over. Remove from the pan, then reduce the heat and add the shallots to the dish. Sweat for 3-4 minutes, then add the chicken pieces back.
Transfer to the oven and cook for 20 minutes. Remove from the oven, add the raw prawns and the rest of the olive oil to the dish. Stir in the paprika, then return to the oven for a further 5 minutes to cook the prawns. Cut into a thick portion of chicken and check that it is cooked through, with no pink showing.
Remove from the oven, allow to stand for a few minutes, then stir through the chopped parsley and adjust the seasoning if necessary. Serve from the dish.
