It is possible to cook brown rice in a slow cooker according to Weight Watchers. Brown rice can be cooked on its own in a slow cooker or as part of a recipe that includes other ingredients.
Cooking brown rice in a slow cooker may be a process of trial-and-error for those who like their rice cooked a specific way. One starting point is to add 2 cups of dry brown rice to a slow cooker along with 5 cups of water and preferred seasonings like salt, pepper and butter or spices like cumin or chili powder. It is a good idea for those who are experimenting with this technique to start out using the highest setting on their slow cooker. The lid should be kept firmly in place for about three hours. After this point, the lid can be removed so the chef can test the rice and make appropriate adjustments if necessary.
