Instructions

  1. Step 1: Combine 2 tsp ground cumin, 1 tsp dried oregano, 1/4 tsp ground cloves, 1 tbsp chipotle chili powder, 3 minced garlic cloves, 2 tsp kosher salt, and 1 tsp black pepper in a small bowl. Rub this spice mixture all over 1.5 pounds beef chuck roast.
  2. Step 2: Preheat a grill or grill pan to medium-high heat (about 450°F). Grill the beef roast for 4-5 minutes per side to develop a charred crust, then transfer to a covered pan and cook at 325°F in the oven for 1.5 hours until tender.
  3. Step 3: While the beef cooks, place 1 medium thinly sliced red onion in a bowl and pour over 1/4 cup apple cider vinegar. Toss to coat and let sit at room temperature for 30 minutes to pickle.
  4. Step 4: Remove the beef from the oven, let rest for 10 minutes, then shred it finely with two forks.
  5. Step 5: Warm 12 small corn tortillas in a dry skillet over medium heat for 30 seconds each side until pliable and slightly toasted.
  6. Step 6: Assemble tacos by filling each tortilla with shredded beef, topping with pickled onions and 1/4 cup chopped fresh cilantro. Serve immediately with lime wedges for squeezing.
