Instructions

  1. Step 1: Soak 3 dried chipotle peppers in 1 cup hot water for 20 minutes until softened, then blend with 5 minced garlic cloves, 1 tbsp salt, 1 tsp black pepper, 2 tsp ground cumin, 1 tsp dried oregano, and 1/4 cup apple cider vinegar to form a smooth marinade.
  2. Step 2: Rub the marinade all over 3 lbs beef chuck roast and place it in a slow cooker with 1 cup beef broth. Cook on low for 8 hours until the beef is tender and shreddable.
  3. Step 3: Meanwhile, prepare pickled onions by combining 1/2 cup white vinegar, 1/2 cup water, 2 tbsp sugar, and a pinch of salt in a saucepan. Bring to a simmer until the sugar dissolves, then pour over 1 thinly sliced medium red onion in a jar. Let sit for at least 1 hour.
  4. Step 4: Shred the cooked beef with two forks, mixing it with the cooking juices to keep it moist.
  5. Step 5: Warm 8 corn tortillas on a dry skillet over medium heat for about 30 seconds per side until pliable.
  6. Step 6: Serve the shredded barbacoa in the warm tortillas topped with the pickled onions for a balanced smoky and tangy taco experience.
