Add the sliced onions, salt, and sugar to the pot. Stir to coat, then cook over medium heat, stirring every 5–7 minutes, for 45–55 minutes, until the onions are deeply golden brown and jammy throughout. If the onions begin to stick or scorch, add a splash of water (1–2 tbsp) and scrape up any browned bits.
