  3. Step 3: Cover the pan tightly with foil and roast in the oven for 4 to 5 hours until the brisket is fork-tender and the exterior is richly browned.
  4. Step 4: Remove the brisket from the pan, rest for 15 minutes, then slice against the grain and serve with the roasted vegetables and pan juices.
