Melt the unsalted butter in a large skillet over medium heat.
Add the sliced onion and cook for 3-4 minutes until softened.
Stir in the minced garlic and sliced mushrooms, cooking for an additional 5-7 minutes until the mushrooms release their moisture and begin to brown.
Pour in the beef broth, soy sauce, Worcestershire sauce, dried thyme, and black pepper.
Stir well and bring the mixture to a gentle simmer. Cook for 5-7 minutes to allow the flavors to meld. Taste the au jus and adjust seasonings if needed.
Preheat your oven to broil (or 450°F for bake as an alternative).
Place the hoagie rolls or sandwich buns on a baking sheet and lightly toast under the broiler for 1-2 minutes.
Meanwhile, warm the thinly sliced roast beef in the simmering au jus for 2-3 minutes.
Layer the warmed roast beef onto the toasted buns and, if using, place a slice of provolone or Swiss cheese on top.
Return the assembled sandwiches to the oven for 1-2 minutes, just until the cheese melts.
Serve the sandwiches warm with individual bowls of mushroom au jus for dipping.
