  • 1/2 tsp dried sage
  • kosher salt and freshly ground pepper to taste


  • Preheat oven to 350º F/180C.
  • Heat 2 tablespoons olive oil in a large, oven-proof pan or skillet over medium heat. Add onions, season with salt and cook, stirring occasionally, for 15-20 minutes, or until softened and caramelized.

  • Remove onions from heat and transfer to a medium bowl.
