Total Time 9 hours 10 minutes

Ingredients
  

  • 3 pounds chuck roast, cut into approximately 2-inch pieces
  • 1 yellow onion, diced
  • 4 chipotle peppers in adobo sauce, diced
  • 6 cloves garlic, minced
  • 1/4 cup lime juice
  • 2 tbsp apple cider vinegar
  • 1 tbsp cumin
  • 1/2 tbsp dried oregano
  • 2 tsp salt
  • 1 tsp black pepper
  • 1/2 cup beef broth

Instructions
 

  • Cut the chuck roast into approximately 2-inch pieces, trimming away any large pieces of excess fat as you go.
  • Place the beef pieces into the slow cooker. Add the diced yellow onion, chipotle peppers, minced garlic, lime juice, apple cider vinegar, cumin, oregano, salt, black pepper, and beef broth. Stir everything together so the beef is well coated in the seasonings and cooking liquid.
  • Cover and cook on LOW for 8–9 hours or HIGH for 4–5 hours, until the beef is incredibly tender and easily pulls apart with a fork.
    For the most tender, flavorful barbacoa, I prefer cooking the beef low and slow when time allows.
  • Carefully transfer the cooked beef to a cutting board.
  • Using two forks, shred the beef into bite-sized pieces. Discard any large pieces of excess fat as you shred.
  • Return the shredded beef to the slow cooker and stir it into all of those flavorful cooking juices.
  • Let the shredded beef sit in the juices for a few minutes before serving so it can soak up even more flavor.
  • Pile the barbacoa beef into warm tortillas and top with diced red onion, fresh cilantro, and a squeeze of lime juice.
    Or skip the tortillas and serve the beef over rice for an easy barbacoa bowl.
    Enjoy!

Tips for the Best Barbacoa Beef

  • Chuck roast works perfectly. The marbling breaks down during the long cooking time, giving you tender, flavorful shredded beef.
  • Cook it low and slow when possible. While the high setting works when you’re short on time, the low setting gives the beef plenty of time to become incredibly tender.
  • Don’t throw away the cooking liquid! Returning the shredded beef to the slow cooker allows it to absorb those flavorful juices.
  • Adjust the spice level. Chipotle peppers in adobo add smoky heat. Reduce the amount if you prefer a milder barbacoa.
  • Finish with fresh lime. A squeeze of lime over the finished tacos adds the perfect bright, fresh flavor.

Frequently Asked Questions

Is barbacoa beef spicy?

This version has a noticeable kick from the chipotle peppers in adobo, along with lots of smoky flavor. For a milder version, simply reduce the number of chipotle peppers.

What cut of beef is best for slow cooker barbacoa?

Chuck roast is a great choice because it has enough fat and connective tissue to become incredibly tender during a long, slow cook.

Can I make barbacoa ahead of time?

Absolutely! Barbacoa is a great make-ahead meal because the beef stays juicy in its cooking liquid. Store it with some of the juices and reheat before serving.

What can I make with leftover barbacoa?
