Ingredients

  • 3 to 3½ lb beef brisket flat or point cut
  • 1 tablespoon olive oil
  • 2 teaspoons kosher salt
  • 1½ teaspoons black pepper
  • 2 teaspoons paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried thyme or rosemary
  • 1 large yellow onion thinly sliced
  • 4 cloves garlic minced
  • 1 cup beef broth
  • ¼ cup tomato paste
  • 2 tablespoons Worcestershire sauce
  • 2 tablespoons brown sugar
  • 1 tablespoon apple cider vinegar
  • 2 bay leaves
  • Optional for thicker gravy:
  • 2 tablespoons cornstarch
  • 2 tablespoons cold water

Instructions

  • Season the brisket
  • Pat the brisket dry with paper towels. In a small bowl, mix salt, pepper, paprika, garlic powder, onion powder, and thyme. Rub the seasoning evenly over all sides of the brisket.
  • Sear for flavor (optional but recommended)
  • Heat olive oil in a large skillet over medium-high heat. Sear the brisket for 2–3 minutes per side until nicely browned. Transfer to a slow cooker.
  • Build the base
  • Scatter the sliced onions and minced garlic around and on top of the brisket.
  • Mix the sauce
  • In a bowl, whisk together beef broth, tomato paste, Worcestershire sauce, brown sugar, and apple cider vinegar. Pour the mixture over the brisket. Add bay leaves.
  • Slow cook
  • Cover and cook:
  • LOW: 8–10 hours (best for ultra-tender brisket)
  • HIGH: 4–5 hours
  • The brisket is done when it’s fork-tender and easily pulls apart.
  • Rest and slice
  • Remove brisket from the slow cooker and let it rest for 10 minutes. Slice against the grain or shred, depending on preference.
  • Optional gravy
  • Remove bay leaves. Whisk cornstarch and water together, stir into the hot cooking liquid, and cook on HIGH for 10–15 minutes until thickened.
  • Serve
  • Spoon the sauce over the brisket and serve hot.
