Long grain white rice is ideal for stuffed bell peppers. Long grain white rice is a good all-purpose rice, since it cooks quickly, is less sticky than other types of rice and the grains remain separated after cooking.
Other types of long grain rice may be used to stuff bell peppers, such as basmati rice or jasmine rice. Long grain brown rice or wild rice can be used, but both take longer to cook and has a chewier texture and nuttier flavor. Short grain rice, which is starchier and creamier, should not be used. All rice should be cooked according to the package directions, before it is mixed with other ingredients.
