Step-by-Step Instructions
- Season the Beef Roast: Pat a 3.5 lb beef chuck roast dry with paper towels. Season all sides generously with 1 teaspoon salt, 1/2 teaspoon black pepper, 1/2 teaspoon garlic powder, and 1/2 teaspoon onion powder.
- Sear for Flavor (Optional): Heat 1 tablespoon olive oil in a heavy skillet over high heat. Sear the beef roast for 3 to 4 minutes per side until a dark golden crust forms. Transfer the roast into your slow cooker pot.
- Mix the Gravy Sauce: In a bowl, whisk together 1.5 cups low-sodium beef broth, 1 packet brown gravy mix, 1 tablespoon Worcestershire sauce, and 4 minced garlic cloves until combined.
- Add Liquid and Butter: Pour the gravy mixture over the beef roast in the slow cooker. Top the roast with 2 to 3 tablespoons of butter cut into pats.
- Slow Cook to Tenderness: Cover with the lid and cook on LOW for 7 to 8 hours (or on HIGH for 4 to 5 hours) until the beef roast is completely tender and easily pulls apart with two forks.
- Thicken the Gravy: Transfer the roast to a plate and cover loosely with foil. Whisk a cornstarch slurry (2 tablespoons cornstarch mixed with 2 tablespoons cold water) into the remaining hot slow cooker juices. Cover and cook on HIGH for 15 minutes until thick and glossy.
- Assemble and Serve: Make a well in a bowl of warm, creamy mashed potatoes. Place a portion of tender beef roast in the center, shredding gently with two forks, and ladle the hot brown gravy generously over the top. Add extra butter pats if desired and serve hot!Tip: Cooking beef chuck roast on LOW heat produces the most tender, shreddable texture compared to cooking on HIGH.
