Ingredients:
- 3 lb boneless beef chuck roast
- 2 tbsp vegetable oil
- 1 tsp kosher salt
- 1 tsp cracked black pepper
- 1 packet (30g) dry onion soup mix
- 1 cup low-sodium beef broth
- 1 tbsp Worcestershire sauce
- 3 cloves garlic, minced
- 1 lb carrots, cut into 2-inch chunks
- 1.5 lb Yukon Gold potatoes, quartered
- 1 large yellow onion, sliced into wedges
- 2 tbsp cornstarch
- 2 tbsp cold water
Instructions:
- Pat the beef chuck roast dry with paper towels and season generously with salt and pepper.
- Heat vegetable oil in a skillet over medium-high heat until shimmering. Sear the meat for 4–6 minutes per side until a deep, mahogany-colored crust forms, then transfer the meat to the slow cooker.
- Scatter the sliced onions, carrots, and potatoes around and underneath the seared roast.
- In a small bowl, whisk together the beef broth, onion soup mix, Worcestershire sauce, and minced garlic. Pour the mixture evenly over the meat and vegetables.
- Cover and cook on Low for 8 to 10 hours, or on High for 5 to 6 hours, until the meat yields easily to a fork.
- Remove the meat and vegetables to a serving platter and strain the remaining liquid into a saucepan.
- Whisk 2 tbsp of cornstarch with 2 tbsp of cold water; stir this slurry into the simmering liquid for 2–3 minutes until thickened into a glossy gravy.
