Onions and shallots are both from the same plant family. They are both used as ingredients that add flavor to many different meals. Onions are often larger and covered by a soft papery skin. Shallots, on the other hand, are smaller, and they appear to be very long onions. This vegetable divides into cloves, rather than rings. Onions have a bolder, unmistakable taste to them. Onions are used in various foods, such as salads, soups, meatballs, chicken pot pie, stir fry, and stews.
On the other hand, when cooked, shallots tend to lose their flavor, which is the opposite of onions developing their strong flavor through cooking. Shallots are commonly eaten raw. It turns out that both vegetables are good for you. Onions contain fiber, and they are popular tamers of blood sugar and blood pressure. Shallots are high in antioxidants, and much like onions, they are also good for blood pressure and cholesterol.
