How Long to Boil Cabbage
It takes 20 to 30 minutes to boil cabbage, depending on how large the head of cabbage is. Cabbage is popular and pretty easy to cook by boiling it, but it's important to pay attention to make sure that it gets nicely soft without destroying the sweet flavors it can have. When the cabbage is soft instead of rubbery, you'll know it's ready. Drain it immediately and serve it: If you leave cabbage in the pot too long, that's when it starts to get smelly and slimy.
