Caramelized Onions

Caramelized Onions

EverydayCooked

Caramelized onions are slowly cooked onions transformed by the Maillard reaction, developing a deep golden-brown color and rich, sweet flavor. This process breaks down the onions' natural sugars over 30-45 minutes of low-heat cooking in oil or butter, resulting in a tender, jam-like texture that contrasts with raw onions' sharpness. Their concentrated umami enhances dishes from soups to sandwiches while adding modest fat content from the cooking process.
