Ingredients:
- 3 lb beef chuck roast, trimmed of excess exterior fat
- 1 tsp kosher salt
- 1 tsp black pepper
- 1 tbsp avocado oil
- 1 lb carrots, cut into 2-inch chunks
- 1.5 lb baby Yukon Gold potatoes, halved
- 1 large yellow onion, wedged
- 4 cloves garlic, smashed
- 2 sprigs fresh rosemary
- 3 sprigs fresh thyme
- 2 cups low-sodium beef broth
- 2 tbsp Worcestershire sauce
- 1 tbsp tomato paste
- 1 bay leaf
Instructions:
- Pat the beef chuck roast completely dry with paper towels. Season generously with salt and pepper on all sides.
- Heat avocado oil in a cast iron skillet over medium-high heat until shimmering. Sear the roast for 5–7 minutes per side until a deep, mahogany-colored crust forms. Transfer the meat to the slow cooker.
- Scatter the onion wedges and smashed garlic at the bottom of the slow cooker to create a natural roasting rack. Place the seared beef on top.
- Surround the beef with the potato halves and carrot chunks. Tuck the rosemary, thyme, and bay leaf into the gaps.
- In a small bowl, whisk together the low-sodium beef broth, Worcestershire sauce, and tomato paste until smooth. Pour the mixture around the sides of the beef.
- Cover and cook on Low for 8 hours until the meat reaches an internal temperature of 205°F (96°C) and pulls apart effortlessly with a fork.
- Remove the meat and vegetables to a platter and tent with foil. Strain the cooking liquid into a saucepan.
- Simmer the liquid over medium-high heat for 8–10 minutes until reduced by one-third and the consistency becomes glossy and velvety. Pour the concentrated glaze over the sliced beef.
