How long does it take to cook a 3kg turkey breast

Boned and rolled

In an oven that is set at 180°C / 350ºF / Gas Mark 4, you should allow 20 minutes per pound, plus 20 minutes.

Put in a roasting tin skin-side up and roast for 70 mins plus 20 mins per kg, or until the internal temperature reaches 65-70C. Remove the turkey from the oven and rest in a warm place for 20 mins.
