Instructions

  1. Step 1: Combine 4 minced garlic cloves, 2 chopped chipotle peppers in adobo, 1 tbsp ground cumin, 1 tsp dried oregano, 1 tsp salt, 1/2 tsp black pepper, and 1 cup beef broth in a blender and puree until smooth.
  2. Step 2: Cut 2 lbs beef chuck roast into large chunks and place into a slow cooker. Pour the blended sauce over the beef and cook on low for 8 hours until the meat is tender and shreds easily.
  3. Step 3: While the beef cooks, prepare pickled onions by combining 1/2 cup white vinegar, 1/2 cup water, and 2 tbsp granulated sugar in a saucepan. Bring to a simmer over medium heat until sugar dissolves, then pour over 1 thinly sliced medium red onion in a jar. Let cool to room temperature and refrigerate.
  4. Step 4: When the beef is done, shred it with two forks and keep warm.
  5. Step 5: Warm 12 small corn tortillas on a dry skillet over medium heat for 30 seconds per side until pliable and slightly toasted.
  6. Step 6: Assemble tacos by filling each tortilla with a generous scoop of shredded barbacoa, topping with pickled red onions and 1/4 cup chopped fresh cilantro.
