01 - Scatter the chopped onion and minced garlic evenly across the bottom of the slow cooker insert.
02 - Arrange the trimmed chuck roast chunks over the onion and garlic layer in the slow cooker.
03 - In a small mixing bowl, whisk together the chopped chipotle peppers, lime juice, ground cumin, dried oregano, smoked paprika, salt, black pepper, apple cider vinegar, and beef broth until well combined.
04 - Pour the seasoning sauce evenly over the beef chunks and tuck the bay leaves into the liquid.
05 - Secure the lid and cook on the low setting for 8 hours, or until the beef is fork-tender and shreds apart effortlessly.
06 - Discard the bay leaves. Using two forks, shred the beef directly in the slow cooker and stir thoroughly to coat all the meat with the accumulated juices.
07 - Serve hot with warm tortillas, over steamed rice, or in burrito bowls, garnished with chopped cilantro, diced onions, lime wedges, and pickled red onions.
