What is the proper method for cooking grilled onions?

Grilled onions are best prepared on a grill, where they can take on a smoky flavor and caramelize properly. The method of cooking them on the grill allows the natural sugars in the onions to caramelize, leading to a rich, sweet taste and a tender texture. Adding oil, salt, and pepper enhances the flavor and prevents the onions from sticking to the grill.

When prepared this way, the onions can develop a beautiful char and grill marks, which contribute not only to their taste but also their appearance, making them more appealing as a topping for burgers or in various dishes. This technique also combines the cooking method with seasoning right from the start, ensuring that every bite is flavorful.

The other methods mentioned don't yield the same results in terms of flavor or texture. Cooking in water, for instance, can reduce the natural sweetness and alter the texture, resulting in a softer and watery product. Frying without seasoning would lack the depth of flavor that seasoning provides. Hence, grilling onions with the right combination of ingredients is the optimal method for achieving the desired taste and texture.
