Ingredients

  • 6 large red onions, peeled and sliced very thinly
  • ¾ cup brown sugar, firmly packed
  • 1 Tbsp. extra-virgin olive oil
  • 3 cups dry red wine
  • ½ cup aged balsamic vinegar
  • ½ tsp. salt
  • ½ tsp. ground black pepper

Directions

  • In a heavy nonstick skillet, combine onions and sugar with olive oil; heat over medium-high heat. Cook uncovered for 25 minutes, or until onions turn golden and start to caramelize, stirring occasionally.
  • Stir in wine, vinegar, salt, and pepper; bring to a boil over high heat. Reduce heat to low; cook 15 minutes, or until most of the liquid has evaporated, stirring frequently.
