If you like cabbage, you will make this dish over and over again. It keeps well in the refrigerator and can be reheated in the oven or microwave.
Make sure you mash the rice down on the top layer so that it is wet and not dry. You can cover the last hour if you think the rice is not cooking or getting soft. I make this most of the time with long grain rice and it is always done in my oven at about 90 minutes. I have not tried freezing this casserole.
