Ingredients:

• 3 lbs chuck roast (boneless)
• 1 tablespoon olive oil
• Salt and black pepper (to taste)
• 1 large onion, sliced
• 4 garlic cloves, minced
• 10 oz mushrooms (cremini or white), sliced
• 3 carrots, cut into chunks
• 2 cups beef broth
• 2 tablespoons tomato paste
• 1 tablespoon Worcestershire sauce
• 1 teaspoon dried thyme
• 1 teaspoon dried rosemary
• 1 bay leaf
• 1 tablespoon cornstarch (optional, for thickening)
• 2 tablespoons water (optional, for slurry)

Instructions:

1. Sear the Beef: Pat roast dry and season with salt and pepper. Heat oil in a skillet and brown roast on all sides. Transfer to slow cooker.
2. Sauté the Aromatics: In the same skillet, sauté onions and garlic for 2–3 minutes. Add mushrooms and cook until slightly browned.
3. Layer in the Cooker: Add sautéed veggies, carrots, broth, tomato paste, Worcestershire sauce, thyme, rosemary, and bay leaf to the slow cooker.
4. Cook Low and Slow: Cover and cook on low for 8 hours or until the beef is fork-tender.
5. Optional Gravy: Remove roast, whisk cornstarch and water, stir into liquid, and cook on high for 15 minutes to thicken.

Tips:

• Use cremini mushrooms for deeper flavor.
• For best results, brown the roast before slow cooking.
• Don’t skip the tomato paste – it adds rich umami.
• To cut time, use pre-sliced mushrooms and baby carrots.

Variations & Substitutions:

• Swap beef with pork shoulder for a different twist.
• Add potatoes in the last 2 hours for a one-pot meal.
• Use red wine (½ cup) instead of half the broth for a richer flavor.
• Fresh herbs like thyme sprigs can replace dried ones.

Serving Suggestions:

• Serve over mashed potatoes, egg noodles, or buttered rice.
• Pair with a crusty bread or buttery dinner rolls.
• A side of roasted green beans or steamed broccoli balances the richness.
