• 1 tbsp tomato paste
• 2 cups beef broth

• 2 bay leaves
• 2 tsp Worcestershire sauce

Optional Garnish

Step-by-Step Instructions

1. Prepare the Roast

Pat the chuck roast dry using paper towels. Season generously with salt and pepper. Heat olive oil in a skillet over medium-high heat and sear the roast for 2–3 minutes per side until beautifully browned.

2. Cook the Onions

In the same skillet, sauté sliced onions for about 5–6 minutes until softened. Add garlic and tomato paste and cook for another minute until fragrant.

3. Assemble in Slow Cooker

Place the seared roast into the slow cooker. Spoon the onion mixture over the top. Pour in beef broth, white wine, herbs, bay leaves, and Worcestershire sauce.

4. Slow Cook

Cover and cook on low for 7–8 hours or high for 4–5 hours until the meat becomes fork-tender and shreds easily.

5. Finish & Serve

Remove roast and let rest for 10 minutes. Discard bay leaves. Slice or shred the meat and spoon onion gravy over the top. Garnish with fresh parsley.
