Before You Get Started

For the most tender barbacoa, give the beef plenty of time to cook. The LOW setting for 8–9 hours is my preferred method because the longer cooking time allows the chuck roast to become incredibly tender.

Don't worry if the beef isn't completely submerged in the cooking liquid. As it cooks, the beef and onions release additional juices, creating plenty of flavorful liquid for the shredded meat to soak up later.

How to Make Slow Cooker Barbacoa Beef

1. Prepare the Beef

Cut the chuck roast into approximately 2-inch pieces, trimming away any large pieces of excess fat as you go.

2. Add Everything to the Slow Cooker

Place the beef in 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.

3. Slow Cook the Beef

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 and flavorful barbacoa, I prefer cooking the beef low and slow when time allows.

4. Shred the Beef

Carefully transfer the cooked beef to a cutting board or large bowl.

Using two forks, shred the beef into bite-sized pieces. Discard any large pieces of excess fat as you shred.

5. Return the Beef to the Juices

Return the shredded beef to the slow cooker and stir it into the 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.

6. Serve

Pile the barbacoa into warm tortillas and top with diced red onion, fresh cilantro, and a squeeze of fresh lime juice.

You can also serve the beef over rice for an easy barbacoa bowl.

Tips for the Best Barbacoa Beef

• Chuck roast works perfectly. The marbling and connective tissue break 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 all of those flavorful juices.

• Adjust the spice level. Chipotle peppers in adobo add smoky heat. Reduce the amount if you prefer a milder barbacoa.

• Don't skip the fresh lime. A squeeze of lime over the finished tacos adds the perfect bright, fresh flavor.

• Shred the beef while it's warm. It's much easier to pull apart while it's still hot and tender.
