Ingredients:
- 3 lb beef chuck roast, trimmed of excess fat
- 2 tsp kosher salt
- 1 tsp cracked black pepper
- 2 tbsp vegetable oil
- 1 cup beef broth (low sodium)
- 1/2 cup dry red wine
- 1 packet onion soup mix
- 3 cloves garlic, smashed
- 1 lb carrots, cut into 2-inch chunks
- 1.5 lb Yukon Gold potatoes, halved
- 1 large yellow onion, wedged
- 2 tbsp cornstarch
- 3 tbsp cold water
Instructions:
- Pat the beef dry with paper towels and season generously with salt and pepper.
- Heat vegetable oil in a large skillet over medium-high heat until shimmering. Sear the roast for 4–5 minutes per side until a deep mahogany-colored crust forms.
- Transfer the seared beef to the slow cooker.
- Pour the beef broth, red wine, and smashed garlic over the meat, then sprinkle the onion soup mix evenly across the top.
- Arrange the wedged onion, carrot chunks, and halved potatoes around the sides of the beef.
- Cover and cook on LOW for 8 hours until the beef yields easily to a fork.
- Remove the meat and vegetables to a platter and tent with foil.
- Strain 2 cups of the cooking liquid into a small saucepan and bring to a simmer.
- Whisk the cornstarch and cold water into a slurry, then stir it into the simmering liquid.
- Whisk constantly for 2-3 minutes until the gravy is thick and glossy.
