Heat your oven to 220C (200C fan-forced),preferably with a grill setting. Rub a little of the butter over the base of a roasting tray and add the potatoes. Butterfly the chicken by cutting through the breast and pressing it flat on a board. Season both sides of the chicken well with salt.
Chop the garlic and bacon together on a board to combine,then mix with the pepper,half the parsley and the white wine. Place the chicken on top of the potatoes and cover the skin of the chicken with the bacon and garlic mixture.
Roast the chicken for 45 minutes until browned and cooked through. Remove the chicken from the pan to rest,stir the potatoes and return them to the oven for a further 20 to 25 minutes.
Serve the potatoes and chicken together scattered with the remaining parsley.
Adam's tip A chicken can be butterflied by either cutting through the spine of the bird or through its breast. Cutting through the spine is more common,but cutting through the breast of the chicken is easier and reduces the amount of skin that bunches between the drumsticks.
Serving suggestion:Raddichio with raisins and parmesan
