Ingredients:
- 3 lb beef chuck roast
- 2 tbsp vegetable oil
- 1 tsp kosher salt
- 1 tsp cracked black pepper
- 1 packet (30g) onion soup mix
- 1 cup beef broth
- 2 tbsp Worcestershire sauce
- 1 tbsp balsamic vinegar
- 1 lb baby yellow potatoes, halved
- 4 large carrots, cut into 2-inch chunks
- 2 stalks celery, sliced thick
- 1 large yellow onion, sliced into thick wedges
Instructions:
- Pat the beef chuck roast dry with paper towels and season generously with 1 tsp kosher salt and 1 tsp cracked black pepper.
- Heat 2 tbsp vegetable oil in a 12-inch cast iron skillet over medium-high heat until shimmering; sear the meat for 4-6 minutes per side until a deep, mahogany-colored crust forms, then remove and set aside.
- Place the sliced yellow onion, carrots, celery, and halved baby yellow potatoes at the bottom of a 6-quart slow cooker to create a roasting rack.
- Place the seared beef roast directly on top of the vegetables.
- In a small bowl, whisk together 1 packet onion soup mix, 1 cup beef broth, 2 tbsp Worcestershire sauce, and 1 tbsp balsamic vinegar, then pour the mixture evenly over the roast.
- Cover and cook on LOW for 8 to 10 hours, or until the meat reaches an internal temperature of 205°F (96°C) and shreds effortlessly with a fork.
- Carefully remove the meat and vegetables to a platter.
- Strain the remaining liquid into a saucepan and simmer over medium heat for 10 minutes to reduce and thicken into a glossy gravy.
