📝 Ingredients
- 3–4 lb beef chuck roast
- 1 large onion, sliced
- 10–12 garlic cloves, peeled
- 2 cups beef broth
- 3 tablespoons butter
- 2 tablespoons olive oil
- 1 tablespoon Worcestershire sauce
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1½ teaspoons salt

👩🍳 Instructions
- Season the roast: Pat the beef dry. Combine salt, pepper, paprika, garlic powder, onion powder, thyme, and rosemary. Rub the seasoning generously over the entire roast.
- Sear the beef: Heat olive oil in a large skillet over medium-high heat. Brown the roast for 3–4 minutes per side until a deep crust forms.
- Layer the slow cooker: Place sliced onions and garlic cloves in the bottom of the slow cooker.
- Set the browned roast on top of the onions and garlic.
- Pour the beef broth and Worcestershire sauce around the roast. Place butter pieces over the top.
- Cover and cook on LOW for 8–9 hours or HIGH for 4–5 hours, until the beef is fork-tender.
- Carefully remove the roast and allow it to rest for 10–15 minutes.
- Spoon the caramelized onions, garlic, and flavorful juices over the roast. Garnish with fresh parsley.
- Slice or shred the beef and serve with plenty of the garlic-infused cooking juices.

💡 Pro Tips
- Chuck roast is ideal because its marbling becomes wonderfully tender during slow cooking.
- Searing the roast first gives the finished dish a richer, deeper flavor.
- Don’t rush the cooking time—the roast should be easy to pull apart with a fork.
- For thicker gravy, simmer the cooking liquid with a cornstarch slurry after removing the beef.
