A crouton is a piece of sautéed or rebaked bread, often cubed and seasoned, that is used to add texture and flavor to salads, notably the Caesar salad, as an accompaniment to soups, or eaten as a snack food. The word crouton is derived from the French croûton, itself derived from croûte, meaning "crust". Most people consider croutons to come invariably in the shape of small cubes, but they can actually be of any size and shape, up to a very large slice.
