Ingredients
  

Brisket & Rub
  • 5 lb beef brisket Flat cut, trimmed of excess fat
  • 1 tbsp kosher salt
  • 1 tbsp coarse black pepper
  • 1 tsp smoked paprika
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 0.5 tsp cayenne pepper
  • 2 tbsp olive oil
Sauce
  • 1 cup beef broth
  • 0.75 cup ketchup
  • 0.25 cup apple cider vinegar
  • 3 tbsp brown sugar
  • 2 tbsp Worcestershire sauce
  • 1 tbsp yellow mustard
  • 1 tsp chili powder
  • 1 tsp garlic powder
  • 1 large yellow onion thinly sliced
  • 4 clove garlic cloves smashed

Equipment

  • 1 Dutch oven
  • 1 slow cooker

Method
 

Prepare the brisket and rub
  1. Pat the brisket dry with paper towels, so the rub clings and sears properly.
  2. Mix kosher salt, coarse black pepper, smoked paprika, garlic powder, onion powder, and cayenne pepper together and rub generously all over every surface of the brisket.
Sear for a dark crust
  1. Heat olive oil in a large skillet or Dutch oven over high heat until shimmering.
  2. Sear the brisket fat-side down for 3–4 minutes until deeply browned, aiming for a dark, crusty surface.
  3. Flip the brisket and sear the other side for another 3 minutes until browned, using visual color to confirm the crust is set.
Mix the sauce and build the slow cooker
  1. While the brisket sears, whisk beef broth, ketchup, apple cider vinegar, brown sugar, Worcestershire sauce, yellow mustard, and chili powder together until smooth.
  2. Scatter sliced onion and smashed garlic into the bottom of a large slow cooker (6-quart or bigger).
  3. Place the seared brisket on top, fat-side up.
  4. Pour the sauce evenly over the brisket so it won’t fully cover the meat, which is fine.
Slow-cook until fork-tender
  1. Cover and cook on LOW for 9–10 hours, until the brisket is fork-tender and pulls apart easily at the thickest part.
  2. (Alternative timing) Cover and cook on HIGH for 5–6 hours, until the brisket is fork-tender and pulls apart easily at the thickest part.
Rest, slice or shred, and serve
  1. Carefully transfer the brisket to a cutting board and let it rest for 15 minutes so the juices redistribute.
  2. Skim excess fat from the juices left in the slow cooker, leaving behind a richer braising liquid.
  3. Slice the brisket against the grain into thick slabs, or shred it with two forks for sandwiches.
  4. Spoon the rich pan juices generously over the brisket before serving.

Notes

For the best flavor and sliceability, use the LOW cook time and rest the brisket the full 15 minutes before slicing. Store leftovers in an airtight container in the refrigerator for up to 4 days; freeze up to 2 months (thaw in the fridge overnight). For a lower-sugar option, reduce brown sugar by half and use no-sugar ketchup if desired (adjust to taste).
