Instructions

  1. Step 1: Combine 2 lbs pork shoulder cut into 3-inch chunks with 1 cup orange juice, 1/4 cup lime juice, 4 minced garlic cloves, 1 tsp ground cumin, 1 tsp dried oregano, 1 tbsp salt, and 1 tsp black pepper in a slow cooker. Cook on low for 8 hours until pork is tender and shreddable.
  2. Step 2: While pork cooks, prepare pickled onions by bringing 1/2 cup white vinegar, 1/2 cup water, and 1 tbsp sugar to a simmer until sugar dissolves. Pour over 1 medium thinly sliced red onion in a jar and let sit at least 30 minutes.
  3. Step 3: Remove pork from slow cooker, shred with two forks, and heat 2 tbsp vegetable oil in a large skillet over medium-high heat. Add shredded pork and cook for 5-7 minutes until edges are crisp and caramelized.
  4. Step 4: Warm 12 corn tortillas on a dry skillet over medium heat for 30 seconds per side.
  5. Step 5: Assemble tacos by placing a generous scoop of carnitas on each tortilla, topping with pickled onions and 1 tbsp fresh cilantro leaves. Serve immediately.
