Onion Jam


  • 1 ½ lbs onions
  • 3 Tbsp butter
  • ¼ c sugar
  • 1 c dry red wine
  • ¼ c balsamic vinegar (plus 2 to 3 tsp more if needed)
  • Salt to taste



  1. Peel and slice onions in half and then into thin slices.
  2. Heat skillet over medium heat and add butter. When melted, add onions and sugar. Cook, stirring occasionally until onions are soft and beginning to caramelize, about 10-15 minutes.
  3. Add wine and ¼ cup balsamic vinegar and stir until bubbly. Reduce heat and simmer until liquids have evaporated, about 15-20 minutes.
  4. Remove from heat, sprinkle in some salt. Taste to see if additional vinegar is needed for balanced sweetness and tartness.
