Place your turkey breast side down in your air fryer basket. Spray the skin with extra virgin olive oil. Season all visible skin with salt, pepper, and half the mixed herbs. Air fry for 25 minutes at 180c/360f.
Check to see if the turkey is cooked by slicing at the thickest part of the breast and checking that it is piping hot and not pink. If the turkey crown is still not cooked through, cook for a further 15 minutes at the same temperature breast side down again.
