We keep it simple and it works every time. Oven on to 240, chook at room temperature. Coat chicken with olive oil, salt and pepper (or sometimes we cover it with Moroccan spices too). Get a whole lemon, ***** it all over and put in the microwave for 40 seconds. Put the lemon and a bunch of fresh thyme in the cavity and put it in the oven. Turn temp down to 200 and cook for 1 hour 20 minutes. It's Jamie Oliver style and is fantastic.
