Ingredients:
- 3 lb beef chuck roast
- 2 tbsp vegetable oil
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1 lb carrots, cut into 2-inch chunks
- 1.5 lb Yukon Gold potatoes, halved
- 1 medium yellow onion, sliced into thick rings
- 4 cloves garlic, smashed
- 2 cups low-sodium beef broth
- 2 tbsp tomato paste
- 1 tbsp Worcestershire sauce
- 1 tsp dried rosemary
- 2 tbsp cornstarch
- 2 tbsp cold water
Instructions:
- Pat the beef roast completely dry with paper towels and season generously with salt and pepper.
- Heat oil in a skillet over medium-high heat; sear the roast for 4-5 minutes per side until a deep mahogany crust forms, then transfer to the slow cooker.
- Place sliced onion rings and smashed garlic at the bottom of the slow cooker to create a flavor rack.
- Set the seared roast on top of the onions and surround the beef with potato halves and carrot chunks.
- Whisk together beef broth, tomato paste, Worcestershire sauce, and dried rosemary; pour the liquid over the roast.
- Cover and cook on Low for 8 hours.
- Remove the beef and vegetables to a serving platter and tent with foil.
- Whisk cornstarch and cold water to create a slurry, stir into the remaining slow cooker liquid, and simmer until thickened to create a gravy.
