1 Check oven has reached temperature, 2  Roast chicken for 80 minutes at 190 Â°C (375 Â°F-Gas 5). 3  Increase the oven heat to 220 Â°C (425 Â°F-Gas 7), for the final 15 minutes to turn the skin crisp and golden.4  Total cooking time 95 minutes. Let bird breath for 10 minutes. 2  Place into suitable roasting tin. 3  Check oven has reached temperature, 4  Roast bird for 25 minutes at 220 Â°C (425 Â°F-Gas 7). 5  Reduce the oven temperature to 180 Â°C (350 Â°F-Gas 4). 6  Roast bird for 20 minutes per 450g. 7  Remove the joint from the oven and check that juices run clear.
Arrange the chicken pieces in the pan so that all the pieces are skin-side up, and the largest pieces (the breasts) are in the center of the pan. Don't crowd the pan; allow room between the pieces. 3 Bake in the oven for 30 minutes at 400Â°F (205Â°C).This initial high heat will help brown the chicken.hen lower the heat to 350Â°F (175Â°C) and bake for and additional 10-30 minutes more until the juices run clear (not pink) when poked with a sharp knife or the internal temperature of the chicken breasts is 165Â°F (74Â°C) and of the thighs is 170Â°F (77Â°C).
