Sautéed onions are a popular cooking technique that involves cooking onions in a small amount of oil or butter over medium heat. This method allows the onions to soften and develop a sweet, rich flavor as they caramelize. The process typically takes about 10 to 15 minutes, depending on the desired level of tenderness and color. Sautéed onions can be used in a variety of dishes, enhancing the taste of everything from soups and stews to sandwiches and pasta. They are a versatile ingredient that adds depth and complexity to many recipes, making them a staple in many kitchens.
