1 of 1433Rating: 5 stars I have been making my corned beef and cabbage in the crockpot for a long time. The only spice I would recommend is either the packet that comes with the corned beef or some whole peppercorns. Then for the last hour of cooking you can add your cabbage. Started the Corned Beef with Seasoning Packet on Low at 9:00 this morning, added the potatoes, carrots and onions at 2:00 and added cabbage at 4:00.
