Ingredients:
- 3 lb boneless beef chuck roast
- 2 tbsp olive oil
- 1 tsp sea salt
- 1 tsp cracked black pepper
- 1 medium yellow onion, diced
- 3 medium carrots, cut into 1-inch chunks
- 2 stalks celery, cut into 1-inch chunks
- 4 cloves garlic, minced
- 2 tbsp tomato paste
- 1 cup low-sodium beef broth
- 1 tbsp balsamic vinegar
- 1 tbsp dried Italian seasoning
- 1 tsp dried rosemary
- 1/2 tsp dried thyme
- 2 tbsp cornstarch
- 2 tbsp water
- Fresh parsley for garnish
Instructions:
- Pat the 3 lb boneless beef chuck roast dry with paper towels and season all sides generously with 1 tsp sea salt and 1 tsp cracked black pepper.
- Heat 2 tbsp olive oil in a skillet over medium-high heat until shimmering; sear the roast for 4-5 minutes per side until a dark golden crust forms, then transfer the meat to the slow cooker.
- In the same skillet using the leftover beef fat, sauté the diced yellow onion, 1-inch carrot chunks, and 1-inch celery chunks for 5 minutes until the onions are translucent.
- Stir in 4 cloves of minced garlic and 2 tbsp tomato paste, cooking for 60 seconds until the paste turns a dark brick red.
- Stir in 1 cup low-sodium beef broth, 1 tbsp balsamic vinegar, 1 tbsp dried Italian seasoning, 1 tsp dried rosemary, and 1/2 tsp dried thyme, scraping the bottom of the pan to release the brown bits.
- Pour the aromatic vegetable mixture over the seared beef in the slow cooker.
- Cover and cook on Low for 8 hours; the roast is ready when it yields easily to a fork and reaches an internal temperature of 145°F (63°C), then let rest for 3 minutes.
- Carefully remove the beef and vegetables to a platter.
- Whisk 2 tbsp cornstarch and 2 tbsp water into a slurry, stir it into the slow cooker liquid, and cook on High for 15 minutes until the sauce is velvety and glossy.
- Spoon the glaze over the beef and vegetables and garnish with fresh parsley.
