Ingredients:

  • 8 kg (4 lb) Boneless Beef Chuck Roast (trimmed of excess silver skin)
  • 2 tsp Fine Sea Salt
  • 1 tsp Freshly Ground Black Pepper
  • 2 Tbsp Neutral Oil (Canola or Vegetable)
  • 1 large Yellow Onion, diced
  • 4-6 cloves Garlic, minced
  • 3 Tbsp Chili Powder (preferably Ancho or New Mexico variety)
  • 1 Tbsp Ground Cumin
  • 1 Tbsp Dried Mexican Oregano
  • 1 tsp Smoked Paprika (optional, for extra smokiness)
  • 2-3 Chipotle Peppers in Adobo Sauce (finely chopped)
  • 1 Tbsp Adobo Sauce
  • 700 ml (3 cups) Beef Broth (low sodium)
  • 120 ml (½ cup) Crushed Tomatoes or Tomato Sauce (optional)
  • 2 Tbsp Apple Cider Vinegar or Fresh Lime Juice

Instructions:

  1. Prepare the Beef: Pat the chuck roast completely dry with paper towels. Season generously on all sides with salt and pepper.
  2. Heat Oil and Sear: Heat the neutral oil in a large frying pan over medium-high heat until shimmering. Sear the chuck roast for 3-4 minutes per side until a deep, dark brown crust (Maillard reaction) is achieved. Transfer the seared roast into the base of the slow cooker.
  3. Sauté Aromatics: Reduce the heat to medium-low in the same pan. Add the diced onion and sauté for 5 minutes until softened. Add the minced garlic and cook for 1 minute until fragrant.
  4. Bloom the Spices: Add the chili powder, cumin, oregano, and smoked paprika to the onion mixture. Cook, stirring constantly, for 30 seconds to release their full flavor potential.
  5. Build the Sauce: Stir in the chopped chipotles, adobo sauce, beef broth, crushed tomatoes (if using), and vinegar or lime juice. Bring the mixture to a slight simmer and immediately turn off the heat.
  6. Combine and Cook: Pour the entire sauce mixture over the beef in the slow cooker. Cover the slow cooker tightly. Cook on the LOW setting for 8-9 hours, or on HIGH for 4-5 hours.
  7. Check for Doneness: The beef is ready when it is completely fork-tender and pulls apart with almost no resistance.
  8. Rest and Remove: Carefully remove the beef roast from the slow cooker and transfer it to a large cutting board or shallow bowl. Allow it to rest for 10 minutes.
  9. Shred: Using two forks or shredding claws, shred the beef entirely. Discard any large pieces of fat or connective tissue.
  10. Reduce the Liquid: Skim off any excess fat floating on the surface of the remaining slow cooker liquid. Pour the liquid into a saucepan and bring to a rolling boil over high heat.
  11. Concentrate the Sauce: Reduce the liquid until it has thickened slightly and concentrated in flavor (about 10-15 minutes). This is the finishing sauce.
  12. Combine and Serve: Return the shredded beef to the slow cooker or saucepan and toss thoroughly with the reduced sauce to coat. Taste and adjust seasoning (salt/pepper) if necessary. Serve hot.
