Cover the steaks with parchment paper and press down to an even 1-inch thickness with your hand or a meat mallet (don't whack it, just press). Season both sides with salt and pepper.
In a glass measuring cup, whisk together the broth, Dijon mustard, Worcestershire sauce.
In a medium pan over medium high heat, melt the butter or heat the oil. Once hot, add the steaks and sear on both sides for about 3 to 4 minutes each (medium rare). Remove to a plate.
Add the shallots to the pan and sauté until tender, about 2 minutes. Stir in the cognac to deglaze the pan, then cook until most of it has evaporated.
Add the broth mixture to the pan and cook until slightly thicker, about 3 minutes. Stir in the heavy cream and continue to cook until thickened, 2 to 3 minutes more.
Return the steaks and any accumulated juices back into the pan. Sprinkle with chopped chives or green onion.
