Preheat the oven to gas mark 8(210-230 degrees Celsius)Take the chicken out of fridge around one hour prior to make sure that it reaches room temperature.Then, in your roasting tin, add the dry herbs( apart from the rosemary and thyme sprigs) and shake to combine. Cut two garlic cloves in half and rub generously all over the chicken. Then rub the chicken with olive oil and place in the roasting tin. Cover completely with the seasonings(including the cavity).Then,using a knife, make holes all over the chicken and push the Rosemary and thyme sprigs into the holes. Leave it for approx. 15 mins to absorb the flavours.
