#### **Step 1: Prepare and Roast the Beef**
Preheat your oven to **325°F (165°C)**. Rub the beef roast with olive oil, salt, pepper, garlic powder, onion powder, thyme, and rosemary. Place in a roasting pan and cook in the oven for **2½ to 3 hours**, or until the internal temperature reaches **195°F (90°C)** for tender, pull-apart meat. Let the beef rest for **15 minutes** before slicing thinly.
#### **Step 2: Make the Au Jus**
While the beef is roasting, combine the beef broth, quartered onion, garlic, bay leaf, and Worcestershire sauce in a small saucepan. Bring to a simmer over medium heat and let cook for **15-20 minutes**. Strain the broth, adjust seasoning with salt and pepper, and keep warm.
#### **Step 3: Assemble the Sandwiches**
Place a generous layer of sliced beef on the bottom half of each roll. If desired, add a slice of provolone or mozzarella cheese. Drizzle plenty of hot au jus over the beef. Cap with the top half of the roll.
#### **Step 4: Serve & Enjoy**
Serve the sandwiches immediately with an extra small bowl of au jus on the side for dipping. Enjoy the explosion of rich, melt-in-your-mouth flavors in every bite.
