Begin your Pulled Beef Sandwich by seasoning the beef chuck roast generously with salt, pepper, and your choice of optional spices, such as garlic powder or paprika. This seasoning will enhance the rich flavor of the meat. Ensure an even coating; this should take about 5 minutes.

Place the seasoned beef chuck roast into a slow cooker. Set it to cook on low for approximately 8 hours, allowing the magic of slow cooking to tenderize the meat until it easily shreds with a fork.

Once the cooking time is up, carefully remove the chuck roast from the slow cooker and place it on a large cutting board. Allow it to rest for a few minutes before shredding it into bite-sized pieces using two forks.

In a large mixing bowl, combine the shredded beef with your favorite barbecue sauce, ensuring every piece is well-coated. This should take about 2–3 minutes.

Now it's time to assemble your Pulled Beef Sandwich! Pile the saucy, shredded beef onto the soft sandwich rolls, and if desired, add sliced onions, pickles, or coleslaw on top.
