Heat a large skillet over medium-high heat. Season the beef chuck roast generously with salt and pepper. Once the pan is hot, sear the roast on all sides until browned (about 3-4 minutes per side). This step enhances flavor.
02 -
Layer the sliced onions and minced garlic at the bottom of a slow cooker. This creates a flavorful base for the beef.
03 -
Place the seared chuck roast on top of the onion and garlic layer in the slow cooker.
04 -
In a bowl, mix the beef broth, French onion soup, Worcestershire sauce, thyme, and rosemary. Pour this mixture over the roast inside the slow cooker.
05 -
Cover the slow cooker and cook on low heat for 8 hours or high heat for 4 hours, until the beef is tender and shreds easily with a fork.
06 -
Remove the cooked roast from the slow cooker and place it on a cutting board. Use two forks to shred the meat into bite-sized pieces.
07 -
Optional: Strain the juices in the slow cooker to remove onions and garlic for a clear au jus. Keep the au jus warm for serving.
08 -
Slice the hoagie rolls and fill each roll with shredded beef. Top each sandwich with 2 slices of provolone cheese.
09 -
Place the assembled sandwiches under a broiler for 2-3 minutes or use a sandwich press until the cheese is melted and bubbly.

Serve the sandwiches warm with a side of au jus for dipping. Garnish with chopped parsley for an extra touch of flavor.
