  • Preheat oven to 400°F. Then lightly grease a 9x12" baking-dish. Put aside.

  • Then pour ¼ cup of broth in the pan becomes too dry and keep stirring till onions are browned.
  • OPTIONAL: Pour in balsamic vinegar, white wine or sherry to deglaze the pan and add some extra tastes to the onions. Let cook for a moment before the sauce thickens slightly.

  • Transfer the remaining caramelized onions in the skillet into the prepared baking-dish. Mix in remaining ¼ cup of broth. Put aside.
  • Heat oil in exactly the exact same skillet over medium-high-heat. Sear the stuffed chicken breasts for 4 minutes each side till browned. (They won't be completely cooked. You may finish off them in the oven).
  • Top with remaining chopped thyme and then bake for 15-20 minutes till completely cooked.
  • Discard toothpicks. Serve with pan juices and onions.
