Ingredients

Instructions

  1. Step 1: Combine 2 chipotle peppers in adobo sauce, 4 minced garlic cloves, 1 tbsp ground cumin, 1 tsp dried oregano, 1 tsp sea salt, and 1/2 tsp black pepper in a blender with 1/2 cup beef broth. Blend until smooth to form the barbacoa marinade.
  2. Step 2: Place 2 lbs beef chuck roast in a slow cooker and pour the marinade over it, coating well. Cook on low for 8 hours until the beef is tender enough to shred easily.
  3. Step 3: While the beef cooks, prepare pickled red onions by combining 1/2 cup apple cider vinegar, 1/2 tsp sea salt, and thinly sliced 1 medium red onion in a jar. Let sit at room temperature for at least 30 minutes.
  4. Step 4: When the beef is done, shred it using two forks and mix it with the cooking juices for extra flavor.
  5. Step 5: Warm 12 corn tortillas in a dry skillet over medium heat for 30 seconds each side until pliable and slightly toasted.
  6. Step 6: Assemble the tacos by placing generous portions of shredded barbacoa beef on each tortilla, topping with pickled red onions and 1/4 cup chopped fresh cilantro. Serve immediately.
