Ingredients

Instructions

  1. Step 1: Season 3 lbs beef chuck roast generously with 2 tsp salt and 1 tsp black pepper on all sides.
  2. Step 2: Heat 2 tbsp olive oil in a large skillet over medium-high heat. Sear the roast for 4 minutes per side until deeply browned and crusty. Transfer to the slow cooker.
  3. Step 3: In the same skillet, add 1 large sliced yellow onion and 4 minced garlic cloves. Sauté for 3 minutes until softened and fragrant, scraping up browned bits.
  4. Step 4: Stir in 2 tbsp tomato paste and cook for 1 minute. Pour in 2 cups beef broth, stirring to combine.
  5. Step 5: Pour the broth mixture over the beef in the slow cooker. Add 4 carrots cut into 2-inch pieces, 3 parsnips cut into 2-inch pieces, 1 lb quartered red potatoes, 3 fresh thyme sprigs, and 2 bay leaves.
  6. Step 6: Cover and cook on low for 8 hours or on high for 4-5 hours until beef is fork-tender and vegetables are cooked through.
  7. Step 7: Remove bay leaves and thyme sprigs before serving. Slice or shred the beef and serve with the root vegetables and cooking juices spooned over the top.
