How long do you cook a 1.5kg boned turkey crown?

1.5kg equals 3.3lbs turkey should be cooked for 20 minutes per pound and 20 minutes should be added to the total cooking time. So at least 1hour and 20 minutes should see the turkey cooked! Check it's cooked by inserting a knife or skewer into the thickest part of the turkey leg, ensure that the juices run clear and your turkey is then fully cooked.
