how long does rice cooker take to cook rice
(Laura Vryhof/Demand Media) One cup of regular long, medium, or short grain rice typically takes 15 minutes to cook in a rice cooker, parboiled rice tends to take 20 minutes for 1 cup, and 1 cup of whole grain rice can take between 40 and 45 minutes. For firmer long grain rice, reduce the liquid from the manufacturer-recommended amount of 2 cups to 1 3/4 cups.
