Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Season 3 lbs beef brisket with 1 1/2 tsp salt and 1 tsp black pepper, then sear the brisket for 4 minutes per side until golden brown and caramelized. Transfer brisket to slow cooker.
  2. Step 2: Add 4 peeled and cut carrots, 3 peeled and cut parsnips, and 1 quartered large yellow onion around the brisket in the slow cooker. Stir together 2 cups beef broth, 4 minced garlic cloves, 2 tbsp Worcestershire sauce, and 1 tsp dried thyme; pour evenly over the brisket and vegetables.
  3. Step 3: Cover and cook on low for 8 hours until the brisket is fork-tender and the root vegetables are soft. Remove brisket and slice against the grain; serve with vegetables and spoon some cooking juices over the top.
