Prepare the Brisket:
Pat brisket dry. In a small bowl, mix paprika, garlic powder, onion powder, chili powder, brown sugar, salt, and pepper. Rub the spice mix all over the brisket.
Sear (Optional):
Heat olive oil in a skillet over medium-high heat. Sear brisket for 2–3 minutes per side until browned. (Adds flavor but can be skipped for ease.)
Slow Cook:
Place brisket in the slow cooker. Pour barbecue sauce, beef broth, and Worcestershire over it. Cover and cook on LOW for 8 hours or HIGH for 4–5 hours, until the meat is fork-tender.
Shred the Brisket:
Remove brisket and let rest 10 minutes. Shred using two forks, discarding any large fat pieces. Return meat to the slow cooker and stir into the sauce.
Assemble Sandwiches:
Toast buns if desired. Pile brisket onto each bun and top with extra BBQ sauce, slaw, or pickles.
