White onions are a type of onion with a white or off-white skin and a mild, slightly sweet flavor. They're commonly used in cooking and salads for their crisp texture and subtle taste. White onions can be sliced thinly and added raw to sandwiches, salads, and salsas, or cooked in soups, stir-fries, and sauces. They're also popular for pickling and marinating.
