A saucepan and a saucier are similar in nature as both have a long handle and can be used to make sauces, boil pasta and saute food. The major difference is its shape. A saucepan has straight sides, similar to a saute pan but taller. A saucier is rounded and shaped like a bowl, ideal to use with a whisk, spoon or spatula.
