Follow these simple steps to create your Slow Cooker BBQ Beef Brisket:

1. Prepare the Brisket: Trim excess fat from the brisket if necessary, then rub it with olive oil, salt, pepper, paprika, garlic powder, and onion powder.
2. Sear the Brisket: In a skillet over medium-high heat, sear the brisket on all sides until browned (about 4-5 minutes per side). This step adds depth of flavor.
3. Transfer to Slow Cooker: Place the seared brisket in the slow cooker.
4. Add Liquid Ingredients: Pour in the beef broth, BBQ sauce, Worcestershire sauce, and apple cider vinegar, ensuring the brisket is well-covered.
5. Set the Cooker: Cover and cook on low for 8-10 hours or on high for 4-5 hours until the brisket is fork-tender.
6. Rest the Brisket: Once cooked, carefully remove the brisket from the slow cooker and place it on a cutting board. Let it rest for about 15-20 minutes.
7. Shred or Slice: After resting, slice or shred the brisket against the grain for optimal tenderness.
8. Serve: Drizzle some of the cooking liquid or extra BBQ sauce over the sliced brisket before serving.

These steps will lead you to a flavorful, melt-in-your-mouth brisket that everyone will rave about.
