  • 3 Tbsp butter
  • 2 tsp olive oil
  • 45 large yellow or white onions peeled and sliced in half
  • 1/4 tsp black pepper
  • 2 sprigs fresh thyme (or 1/2 tsp dried)
  • 3 cloves garlic minced
  • 1 Tbsp balsamic vinegar (or red wine or sherry)
  • 2/3 cup reduced sodium beef broth divided
  • 4 boneless skinless chicken breasts
  • 1/2 tsp kosher salt
  • 1/2 tsp black pepper
  • 1/2 tsp dried thyme
  • 1 tsp garlic powder
  • 1 cup shredded mozzarella or gruyere
  • 1/3 cup shredded parmesan (fresh is best)


  • Heat a large skillet over MED/MED-HIGH heat. Add butter and olive oil and sliced onions. Season with 1/4 tsp pepper. Add thyme sprigs and cook 8 minutes, stirring very occasionally.
  • While onions are cooking, preheat oven to 400 F degrees and butter a 9×13″ baking dish. Set aside.
  • After 8 minutes, reduce the heat on the pan of onions down to MED/MED-LOW, and cook another 15 minutes or so, stirring occasionally.
  • Stir in garlic, cook 1 minute. Stir in balsamic vinegar and 1/3 cup of the beef broth. Stir and cook another minute or so, until onion mixture is thick and jam-like in consistency.
  • Add about a 1/2 cup of the caramelized onions to the prepared baking dish and add the remaining 1/3 cup beef broth to the dish. Stir.
