How long does cabbage need to cook?
I make cabbage a few times a week and because it can be eaten raw you cannot under cook it. Although you can over cook it so I would wait until the roast has maybe 30 min til done then add the cabbage. This is a guess because I have never made this dish but I do know if you over cook cabbage it will make your tummy hurt bad. HOPE I HELPED.

Reply:I put in the same time as my roast and its done when the roast is done, ignore the other responds, I love cooked cabbage also.
