  • 1 tbsp olive oil
  • 1 medium red onion diced (about 2 cups)
  • several sprigs fresh thyme
  • 1/2 tsp kosher salt
  • 1/4 tsp freshly ground pepper
  • 2 cups blueberries
  • 2 tbsp balsamic vinegar
  • 1/4 cup honey
  • 2 tbsp brown sugar
  • 1/4 cup red wine
  • 1 tsp lemon juice


  • In a Dutch oven, heat olive oil over medium heat. Add onion, salt, pepper, and thyme, and reduce to medium low. Cook for 30 -35 minutes or until caramelized, stirring occasionally.
  • Add blueberries, vinegar, brown sugar, honey, and red wine and cook until berries are enlarged and about to burst and liquid is reduced, about 5-10 minutes. Add lemon juice and stir, smashing berries. Remove thyme stems.
  • Remove from heat and cool to room temperature. Spoon into a clean jar and refrigerate until thickened. Use to top crostini or burgers.
