6" french or hoagie rolls, sliced in half diagonally
6 tablespoons
butter, softened
2 teaspoons
garlic powder, granulated
2 cups
grated gruyere or Swiss cheese
minced parsley for garnish, optional
Au Jus
4 cups
beef stock
¼ teaspoon
dried thyme
1 teaspoon
salt
1 teaspoon
sherry wine
1 tablespoon

2 teaspoons

2 teaspoons

Method
Heat a large cast iron skillet over high heat. Generously salt and pepper the steak and sear it until it reaches medium rare (135°F on an instant read thermometer), depending on thickness about 3 minutes each side. Let the steak rest for 5 minutes. Slice the steak into strips, as thin as possible against the grain and set aside.
In a medium sized saucepan set over medium heat, whisk the beef stock, dried thyme, salt, sherry, Worcestershire, garlic and onion powder, until fully combined. Simmer for 5 minutes.
Butter the inside of the each of the french or hoagie rolls and sprinkle with garlic powder and place them open faced on a rimmed baking sheet.
Turn oven broiler on medium. Quickly dip the strips of steak into the broth and place them in even amounts onto one side of each roll. Sprinkle ⅓ cup cheese on each sandwich and arrange them open face on the baking sheet.
Place the baking sheet under the broiler until cheese begins to melt, watching carefully for about 2 minutes. Remove from oven and sprinkle with parsley if desired.
In small cocottes or ramekins ladle ¾ cup serving of au jus into each container. Serve au jus with the warm sandwich.
