Slow Cooker Brisket Sandwich with Vinegar Slaw

Steps

1. 1

   Season the brisket

   • Pat the trimmed brisket dry with paper towels.
   • Season both sides evenly with 1 tsp kosher salt and ½ tsp freshly ground black pepper.
   • Let sit at room temperature for 10 minutes while you prepare the slow cooker.

   Ready when: Brisket is evenly seasoned and has lost surface moisture

   Tip: Patting the brisket dry helps it brown slightly when added to the slow cooker and prevents excess liquid from diluting the braising liquid.

2. 2

   Build the slow cooker bed

   • Add the sliced onion and crushed garlic to the bottom of a 6-quart slow cooker.
   • Pour in 1 cup unsalted beef broth and 2 tbsp Worcestershire sauce.
   • Stir gently to combine.

   Ready when: Onions and garlic are submerged in broth

   Tip: The bed of aromatics prevents the brisket from sticking to the bottom and flavors the braising liquid.

3. 3

   Add brisket to slow cooker

   • Place the seasoned brisket fat-side up on the aromatics, pressing it gently into the liquid so that about half the meat is submerged.
   • The fat cap should face upward to baste the meat as it cooks.

   Ready when: Brisket is nestled in the liquid with fat cap facing up

   Tip: Fat side up allows the rendered fat to self-baste the meat, keeping it moist and flavorful throughout the long cook.

4. 4

   Braise on low heatOven 205°F / 95°C

   • Cover the slow cooker and set it to low heat.
   • Cook for 8 to 9 hours.
   • The brisket is done when it's fork-tender and shreds easily with minimal pressure.
   • An instant-read thermometer inserted into the thickest part should read 190–205°F (87–96°C).
   • Do not open the lid during cooking.

   Ready when: Internal temperature 190–205°F (87–96°C); meat shreds easily with a fork

   Tip: Resist opening the lid frequently—each opening adds 15–20 minutes to the cooking time. The low, steady heat is what transforms tough collagen into silky tenderness.

5. 5

   Shred the brisket

   • Once the brisket is fully cooked, transfer it to a cutting board.
   • Using two forks or a serrated knife, shred the meat into bite-sized pieces, removing any remaining fat deposits.
   • Strain the braising liquid into a large bowl, discarding the onions and garlic, and skim off excess fat from the surface using a spoon or fat separator.

   Ready when: Brisket is shredded into small, tender pieces; braising liquid is strained

   Tip: Working quickly while the brisket is still warm makes shredding easier. Save a bit of the de-fatted braising liquid to add back to the shredded meat for moisture.

6. 6

   Combine brisket with sauceOven 350°F / 175°C

   • Return the shredded brisket to the slow cooker.
   • Pour in 1.5 cups barbecue sauce and ½ cup of the reserved braising liquid (or more to taste).
   • Stir until evenly coated.
   • Set the slow cooker to warm and keep covered until ready to serve (up to 2 hours).
   • The brisket can also be made ahead and reheated in a 350°F oven.

   Ready when: Brisket is evenly coated in sauce and glistens

   Tip: Adding some braising liquid keeps the meat moist and prevents it from drying out during the warm hold. You can adjust the barbecue sauce ratio to your preference—more for saucier sandwiches, less for drier ones.

7. 7

   Make the vinegar slaw

   • While the brisket finishes cooking, combine 8 cups sliced green cabbage and 1 julienned carrot in a large mixing bowl.
   • Sprinkle with 1 tsp kosher salt and toss well.
   • Let sit for 5 minutes to allow the cabbage to wilt slightly and release moisture.
   • In a small bowl, whisk together ½ cup apple cider vinegar and 3 tbsp granulated sugar until the sugar dissolves.
   • Pour the vinegar mixture over the cabbage and carrot, tossing until everything is well coated.
   • The slaw can be made 1–2 hours ahead and refrigerated; it will become softer and more flavorful as it sits.

   Ready when: Slaw is well coated in vinegar mixture; cabbage is slightly wilted

   Tip: Salting the cabbage before adding the vinegar dressing draws out water and prevents a watery finished slaw. The acidity of the apple cider vinegar cuts through the richness of the brisket beautifully.

8. 8

   Toast the brioche bunsOven 350°F / 175°C

   • About 20 minutes before serving, preheat your oven to 350°F (176°C).
   • Split the brioche buns and arrange them cut-side up on a 9×13-inch baking sheet.
   • Lightly brush the cut surfaces with 2 tbsp melted unsalted butter.
   • Bake for 5–6 minutes until golden brown and lightly crisp on the edges.

   Ready when: Cut surfaces are golden brown; edges are lightly crisped

   Tip: Toasting the buns adds structure so they won't fall apart under the weight of the juicy brisket and slaw. Don't toast too long or they'll become hard.

9. 9

   Assemble the sandwiches

   • Divide the warm shredded brisket evenly among the bottom halves of the toasted brioche buns (about ¾ cup per sandwich).
   • Top each portion generously with vinegar slaw, allowing some of the sharp, tangy liquid to drip onto the meat.
   • Cap with the top bun halves.
   • Serve immediately while the brisket is warm and the buns are still crisp.

   Ready when: Sandwiches are stacked and ready to eat

   Tip: Build the sandwiches just before serving so the warm brisket doesn't make the buns soggy. If you prefer saucier sandwiches, spoon a little extra vinegar slaw liquid over the meat before topping with slaw.
