One cup (240 mL) of uncooked rice will generate anywhere from 1 1/2 cups (360 mL) to three cups (720 mL) of cooked rice, depending on variety. [1] X Research source Leave enough space for this expansion to prevent the rice cooker from spilling over.
White rice sold in the United States is required by law to be enriched with powdered iron, niacin, thiamin, or folic acid; these vitamins and minerals are usually removed by washing. If your rice cooker has a non-stick bowl, wash the rice (prior to cooking) in a colander with several washes/rinses/drains. Replacement non-stick bowls are very expensive.
White, long grain - 1 3/4 cups of water per 1 cup of rice (420 mL water per 240 mL rice) White, medium grain - 1 1/2 cups of water per 1 cup of rice (360 mL water per 240 mL rice) White, short grain - 1 1/4 cups of water per 1 cup of rice (300 mL water per 240 mL rice) Brown, long grain - 2 1/4 cups of water per 1 cup of rice (520 mL water per 240 mL rice) Sold as “parboiled” (not half-cooked at home) - 2 cups of water per 1 cup of rice For Indian style rices like Basmati or Jasmine, less water is needed as a drier rice is desired, use no more than 1 1/2 cups of water per 1 cup of rice. Use only 1 to 1 if you washed the rice previously. It is ok to add bay leaves or cardamom pods directly to the rice cooker to enhance the flavor.
Another option is to add chicken stock instead of just water.
You do not need to stir the rice under the water level. This may release excess starch and result in clumpier or stickier rice.
Don’t lift the lid to check on the rice. The cooking process depends on the development of steam inside the pot, so letting steam escape by opening the lid may result in improperly cooked rice. The rice cooker automatically turns off when the temperature inside the pot exceeds waters boiling point (212 degrees F or 100 degrees C at sea level), which will not happen until all the free water has vaporized.

If the rice is not ready to eat, see troubleshooting.
Adding it back to the rice cooker without enough water to cover it could result in burning, or the rice cooker failing to turn on. Next time, simply add about 1/4–1/2 cup (30–60mL) of water per cup (240 mL) rice to the rice cooker before you turn it on.
On some cookers, you can turn off the warming option entirely, but in this case, you should still eat or refrigerate the rice before it cools to reduce the risk of food poisoning. If you are cooking other ingredients with the rice, those can burn during cooking. Next time, remove any sugary ingredients and cook separately, or any ingredients that you notice burning.
Fry it to remove that excess moisture Turn it into a sweet dessert Add it to any soup, baby food, or homemade meatballs
Consult the rice cooker instructions or contact the manufacturer if you cannot find the correct amount of additional water. The amount necessary varies with altitude.
