Prep Time: 15 minutes | Cook Time: 8–10 hours | Servings: 6–8

Ingredients

For the Beef Roast:

  • 3–4 lb beef chuck roast
  • 2 lbs baby potatoes, halved
  • 1 medium onion, chopped
  • 5 garlic cloves, minced
  • 6 tablespoons unsalted butter, cubed
  • 1 cup beef broth
  • 2 tablespoons olive oil
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried rosemary
  • 1 teaspoon dried thyme
  • 1 teaspoon salt, or to taste
  • ½ teaspoon black pepper
  • 1 tablespoon fresh parsley, chopped (optional)

Step-by-Step Instructions

Step 1: Prepare the Vegetables

Wash the baby potatoes and cut larger ones in half. Place the potatoes and chopped onion evenly across the bottom of a 6-quart slow cooker. Sprinkle with half the minced garlic.

Step 2: Season the Beef

Pat the beef roast dry with paper towels. Rub it with olive oil, then season generously with salt, black pepper, smoked paprika, garlic powder, onion powder, rosemary, and thyme.

Step 3: Sear the Roast (Optional)

Heat a skillet over medium-high heat. Sear the roast for 2–3 minutes on each side until browned. This adds a deeper, richer flavor.

Step 4: Assemble the Slow Cooker

Place the seasoned beef roast directly on top of the potatoes and onions. Add the remaining minced garlic and distribute the butter cubes over the beef.

Step 5: Add the Liquid

Pour the beef broth and Worcestershire sauce around the roast, allowing the seasonings to remain on top.

Step 6: Slow Cook

Cover with the lid and cook:

  • LOW: 8–10 hours
  • HIGH: 5–6 hours

Cook until the beef is fork-tender and the potatoes are soft. For a shreddable chuck roast, the internal temperature often reaches approximately 195–205°F (90–96°C).

Step 7: Shred and Serve

Carefully remove the beef and shred it with two forks or slice it into thick pieces. Spoon the garlic butter cooking juices over the beef and potatoes.

Step 8: Garnish

Sprinkle with freshly chopped parsley and serve warm.

Tips for the Best Results

  • Use chuck roast for the most tender, juicy results.

  • For thicker gravy, stir 1 tablespoon cornstarch mixed with 2 tablespoons cold water into the hot cooking liquid and simmer until thickened.
  • Store leftovers in an airtight container in the refrigerator for up to 3–4 days.
