  • 2 Tablespoons olive oil
  • 1 ½ pounds boneless, skinless chicken breasts
  • 2 onions halved and sliced thinly
  • ¼ cup water
  • teaspoon baking soda
  • 2 Tablespoons flour
  • 2 cups chicken broth or beef broth
  • 1 teaspoon Dijon mustard
  • 1 teaspoon fresh thyme
  • 1 cup shredded Gruyere cheese


  • Heat the oil in a skillet over medium high heat. Add the chicken and cook for 3-4 minutes on each side, or until browned. Transfer to a plate.
  • Add the onion and water. Cover and cook for 5 minutes, until the onions begin to soften. Uncover and stir in the baking soda. Cook, uncovered, for 15 minutes, or until the onions are soft and golden brown, stirring occasionally.
  • Stir in the flour and season with salt and pepper. Whisk in the broth, mustard and thyme. Bring to a rapid simmer.
  • Return the chicken to the pan and cook, covered, until the chicken is cooked through, about 5 minutes.
  • Uncover and top with cheese. Broil for 2-4 minutes, or until the cheese is bubbling and browned (keep a close eye on the pan while it broils to prevent burning).
