Place the chuck roast into the bottom of a slow cooker.
Whisk together the gravy mixes, water, broth and onion soup mix. Pour over the roast in the slow cooker.
Place the lid on top and cook on HIGH for 4-5 hours or LOW for 8-10 hours. The roast has to cook until it shreds perfectly with two forks, which takes hours.
Once done, remove the strings from the beef and discard. Shred the roast into the gravy until mixed throughout.
Serve as is, in sandwiches, or on Yorkshire puddings and more!
