While orzo may be shaped to look like rice, it is actually a form of pasta that is traditionally made from white flour, or semolina.  You’ll often find it in soups, casseroles, salads or in side dishes like this Homemade Rice Pilaf. Another part of the confusion stems from the fact that they are cooked almost identically.  Just like with rice, orzo can be added to soups to cook, or simmered and fluffed… you can even make risotto with it!
