  • 2 tablespoons butter divided
  • 1 tablespoon olive oil
  • 4 chicken breasts pounded or cut to be 1/2 inch thick (or less)
  • salt & pepper to taste
  • 2 whole yellow onions sliced thin
  • 1 teaspoon dried thyme leaves
  • 2 bay leaves
  • 1/2 cup marsala or red wine
  • 1 cup beef broth

Finishing the dish:


  • Place large, nonstick pan over medium heat heat. Add 1 tablespoon butter to the pan. Sprinkle salt and pepper over both sides of the chicken. Add to the preheated pan and brown on both sides and thoroughly cooked to 165 degrees F. Transfer browned chicken to a plate and cover with foil.

  • To the hot pan, add other tablespoon butter and 1 tablespoon olive oil. Add onions, thyme, bay leaves, salt and pepper to the pan and stir to coat in spices, butter and oil. Cook slowly, stirring occasionally for 20-30 minutes or until completely soft and tender. If your onions are coloring before they are tenderizing, your heat may be too high. Reduce heat and continue cooking.

  • Once onions are completely tender and browned all the way though, deglaze pan with marsala wine and cook down by half (this shouldn't take too long). Add in the beef broth. In a small bowl, stir butter and flour together to create a paste. Add to pan to thicken the gravy. Stir and cook 1 minute. Reduce heat to low.
