Add the sliced onions and salt, stirring to coat. Cook over medium heat, stirring every 5 minutes, until the onions are completely softened and a deep golden-amber color throughout, 35–45 minutes. If the onions begin to stick or darken too quickly at any point, reduce the heat to medium-low and add a splash of water.
