Preheat your smoker to 225°F. If you don’t have a smoker, you can use a grill set up for indirect heat.
In a small bowl, mix together the smoked paprika, garlic powder, onion powder, salt, black pepper, and cayenne pepper.
Rub the olive oil all over the chuck roast, then generously apply the spice mixture, ensuring it covers the entire surface.
Place the chuck roast in the smoker and smoke for about 4-5 hours, or until the internal temperature reaches 195°F to 205°F for tender, pull-apart meat.
In a separate bowl, combine the beef broth, Worcestershire sauce, and apple cider vinegar. After the first 2 hours of smoking, baste the roast with this mixture every hour.
Once the roast is done, remove it from the smoker and let it rest for 20-30 minutes before slicing or shredding.
Garnish with fresh parsley before serving.
