Season chuck roast generously with salt and pepper.
In a large skillet, heat olive oil over medium-high heat and sear roast on all sides until browned.
Transfer roast to a slow cooker. Add beef broth, Worcestershire sauce, soy sauce, garlic powder, and onion powder.
Cover and cook on low for 6–8 hours or until meat is tender and shreds easily.
Remove roast, shred with two forks, and return to the juices in the slow cooker.
Toast hoagie rolls if desired. Place shredded beef on rolls and top with provolone cheese.
Serve with a side of the cooking juices for dipping.
