3 pounds beef chuck roast
1 large onion, sliced
3 cloves garlic, minced
1 cup beef broth
2 tablespoons Worcestershire sauce
1 tablespoon Dijon mustard
1 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon dried thyme
1/2 teaspoon dried rosemary
2 bay leaves
1 tablespoon olive oil
6–8 hoagie or French rolls
Optional: 6–8 slices Swiss or provolone cheese
Trim excess fat and pat roast dry.
Sear roast in olive oil until browned on all sides.
Place onions and garlic in the slow cooker.
Add seared roast on top of onions and garlic.
Whisk together broth, Worcestershire sauce, Dijon mustard, salt, pepper, thyme, and rosemary; pour over roast. Add bay leaves.
Cook on low 8–10 hours or high 4–6 hours until fork-tender.
Remove roast, let rest 10 minutes, then slice against the grain.
Strain cooking liquid for au jus and adjust seasoning.
Toast rolls, layer beef and cheese if using, melt cheese briefly.
Serve with warm au jus for dipping.
