This recipe is for a classic corned beef dinner with rutabagas, carrots, onions, potatoes, and cabbage. As an additional option, you can serve the corned beef with a mustard sauce or horseradish sauce. This one-pot meal is a real timesaver on busy days when you can set this to cook while you multitask. It also reheats and freezes well, so making a double portion is not a bad idea. Consider it for your next potluck.
