Ingredients

  • 4 cups sweet onions sliced
  • 1/2 cup 1 stick unsalted butter, cut into pats
  • 1 tablespoon brown sugar
  • 2 tablespoons balsamic vinegar
  • 1 tablespoon lemon juice
  • 1/4 teaspoon salt
  • 1/4 teaspoon pepper

Instructions

  1. Place chopped onions in slow cooker and arrange butter pats on top. Cover slow cooker and cook on LOW for 8 hours, stirring once or twice in between.
  2. After 8 hours, check onions and see how they look and if they’re tender. Season with salt, pepper, brown sugar, lemon juice and balsamic vinaigrette.
  3. Cover again, leaving lid just slightly ajar, and cook for another 2 hours, or until onions have reached desired tenderness and cooking juices have mostly evaporated.
  4. Store in an air-tight container and serve hot or cold.
