caramelize the onions

Meaning

To caramelize onions means to cook them slowly over low heat until they become sweet, soft, and deep golden-brown. This process draws out the natural sugars in the onions and transforms their sharp flavor into a rich, savory sweetness. It requires patience, as rushing the process with high heat will burn them instead.
