A helpful guide for caramelizing onions can be found here
Recipe type: Condiment, Savory Jam, Spread
  • 2 pounds yellow onions, halved, peeled, trimmed, and thinly sliced
  • 2 tablespoons unsalted butter
  • ¾ teaspoons plus ½ teaspoon sugar, divided
  • kosher salt, to taste
  • freshly ground black pepper, to taste
  • 2 tablespoons apple cider vinegar
  1. Heat the butter in a large skillet or saucepan over medium-low heat. Add the onions, sprinkle with salt, and stir. Cover and cook for about 12 minutes, or until the onions have released their liquid.
  2. Increase the heat to medium and cook for about 10 minutes, or until the liquid has evaporated and the onions turn a slight golden color. Sprinkle with sugar, and continue to cook, stirring frequently until the onions are a deep golden brown, 10-25 minutes more. Add the apple cider vinegar to the hot pan, stir, and scrape up the brown bits at the bottom of the pan. Remove from heat.
  3. Transfer the onions to a cutting board or a food processor and finely chop (but don't puree). Add an additional ½ teaspoon of sugar, then season to taste with kosher salt and black pepper.
