Shallots and onions are related, but they're not exactly the same. Shallots are a type of Allium, the same family that includes onions, garlic, and chives. However, shallots have a milder, sweeter flavor than onions and are often used in dishes where a more delicate onion flavor is desired. They have a slightly different texture than onions as well, with a softer, more tender flesh. Shallots are also smaller than onions and typically grow in clusters with multiple bulbs per plant. The bulbs are usually elongated and have a brown papery skin. In contrast, onions are usually round or oblong in shape and have a more distinct papery skin that varies in color depending on the variety.
