Crispy fried onions are often used as a topping to enhance salads, burgers, or sandwiches by adding an extra burst of flavor and crunch. They can also be incorporated into soups or stews to provide additional texture and depth of flavor. Another common use is as a side dish for meat dishes like steak or roast chicken, where they perfectly complement the savory flavors. In Asian cuisine, crispy fried onions are sometimes added as a garnish to sushi or rice dishes, providing an interesting contrast in texture and flavor.
