Step-by-Step Instructions
- Season the skirt or flank steak generously with kosher salt and freshly cracked black pepper. In a hot cast-iron skillet, sear the steak for about 3 minutes on each side for medium-rare, reaching an internal temperature of 135°F. Let the steak rest for 5 minutes before slicing it thinly against the grain.
- In a medium saucepan, combine beef stock, dried thyme, a pinch of salt, sherry wine, Worcestershire sauce, garlic powder, and onion powder. Whisk together and bring to a gentle simmer over medium heat. Simmer for 5 minutes.
- Butter the insides of the French or hoagie rolls with salted butter and sprinkle garlic powder on them. Dip sliced steak into the au jus and arrange inside the rolls.
- Top with Gruyère or Swiss cheese and broil for about 2 minutes, watching closely to prevent burning, until the cheese is bubbling and golden.
- Pour warm au jus into small ramekins for dipping. If desired, garnish sandwiches with parsley and serve immediately.

Notes
Allow seared steak to rest for at least 5 minutes before slicing to retain juices. Use quality ingredients for better flavors.
