Cabbage in general isn’t a vegetable that requires hours of cooking. The exact amount of cooking time depends on the thickness of the shredded cabbage. Properly shredded cabbage can cook inside a soup for under 10 minutes. There are however a lot of people that prefer adding pre-cooked or wilted cabbage into a soup to prevent a crunchy texture. We don't feel that this is necessary, as soups have to generally cook for about 30 minutes, and cabbage only requires 10 minutes to cook. You can also see from our method, that the cabbage in this cabbage carrot soup has about 25 minutes to cook, which will create a very soft end product.
