Step 1

In a large skillet over medium high heat add the oil and sliced onions. Sauté until caramelized 7-10 minutes. Remove and set aside on a plate. Add in the chicken breasts and cook on each side for 3-4 minutes or until cooked throughout and no longer pink. Set aside with the onions.

Step 2

Add in the butter and let melt and add the flour and whisk until combined. Add the beef broth, oregano, and thyme and salt and pepper to taste and let simmer for 1-2 minutes until it starts to thicken.

Step 3

Reduce heat to a simmer and add chicken and onions back to the dish. Top with shredded Swiss cheese and provolone. Broil for 1-2 minutes until cheese is melted.
