🍽️ Step-by-Step Beginner-Friendly Instructions

  1. Prep the beef
    Trim excess fat and cut chuck roast into large, even chunks. Season all sides with salt and pepper.
  2. Sear the meat (optional, but worth it!) 🔥
    Heat oil in a skillet over medium-high heat. Sear beef chunks on all sides until golden brown—about 2–3 minutes per side.
  3. Build the flavor base
    In the slow cooker, layer in chopped onions, garlic, carrots, and celery.
  4. Mix the sauce 🥣
    In a bowl, whisk together beef broth, tomato paste, Worcestershire sauce, smoked paprika, thyme, salt, and pepper. Pour this mixture over the vegetables.
  5. Slow cook the beef
    Place seared beef chunks on top. Cover and cook on low for 8 hours or high for 4 hours, until the beef is fall-apart tender.
  6. Final seasoning & serve
    Taste and adjust seasoning if needed. Shred or slice the beef and serve over a bed of mashed potatoes or buttery egg noodles. 🥔🍽️

💡 Pro Tips
