Ingredients

Instructions

  1. Step 1: In a blender, combine 2 chipotle peppers in adobo sauce, 4 minced garlic cloves, 1 tsp ground cumin, 1 tsp dried oregano, 1 tsp salt, 1/2 tsp black pepper, and 1 cup chicken broth. Blend until smooth to make the marinade.
  2. Step 2: Place 1.5 pounds boneless skinless chicken thighs in a slow cooker and pour the chipotle marinade over the chicken. Toss gently to coat, cover, and cook on low for 6 hours until the chicken is tender and shreds easily.
  3. Step 3: Meanwhile, combine 1/2 cup white vinegar, 1 tbsp sugar, and 1/4 tsp salt in a bowl. Add 1 medium thinly sliced red onion and let it sit for at least 30 minutes to pickle, stirring occasionally.
  4. Step 4: When chicken is done, shred it with two forks in the slow cooker and stir to mix with the sauce.
  5. Step 5: Heat 8 small corn tortillas on a dry skillet over medium heat for 30 seconds per side until warm and pliable.
  6. Step 6: Assemble tacos by spooning shredded chipotle chicken onto each tortilla, topping with pickled red onion and 1/4 cup chopped fresh cilantro. Serve with 4 lime wedges to squeeze over the tacos.
