Method
 

Assemble in the slow cooker
  1. Lightly coat the bottom of a slow cooker with the olive oil. Spread the oil to create an even base layer.
  2. Add the diced onion and minced garlic to the slow cooker and spread evenly. Keep them in a single layer so they cook through.
  3. Place the chicken breasts on top in a single layer. Arrange them so they are not stacked for even shredding.
  4. Pour the diced tomatoes with green chiles over the chicken. Cover as much surface area as possible for consistent flavor.
  5. Mix together the chili powder, cumin, smoked paprika, garlic powder, onion powder, dried oregano, salt, and black pepper, then sprinkle the spice blend evenly over the chicken and tomatoes. Make sure the spices reach all corners of the cooker.
  6. Squeeze the lime juice over everything, then place the lid on the slow cooker. Press the lid down fully to seal in heat and steam.
Slow cook until shred-tender
  1. Cook on LOW for 6–7 hours until the chicken is fully cooked and tender enough to shred easily. Check around the 6-hour mark if your slow cooker runs hot.
  2. Alternatively, cook on HIGH for 3–4 hours until the chicken is fully cooked and tender enough to shred easily. Confirm the thickest piece shreds with light pressure.
Shred and soak in the juices
  1. Remove the chicken breasts and place them on a cutting board. Let them sit briefly so excess steam settles.
  2. Use two forks to shred the meat into chunky, pull-apart pieces. Keep the texture rustic so the tacos don’t become paste-like.
  3. Return the shredded chicken to the slow cooker and stir it into the juices. Mix until the chicken looks evenly coated.
  4. Let the chicken sit on WARM for 10 minutes to soak up all the flavor. Stir once halfway through for even moisture.
Warm tortillas and build tacos
  1. Warm the tortillas in a dry skillet over medium heat for 30 seconds per side. Flip when the tortilla edges look slightly flexible and warm.
  2. Alternatively, wrap the tortillas in a damp paper towel and microwave for 45 seconds. Stop when they are soft and steamy, not dry.
  3. Build your tacos by adding a generous scoop of chicken, shredded cheese, avocado slices, pico de gallo (or salsa), sour cream, fresh cilantro, and a squeeze of lime. Serve immediately while the tortillas are warm.

Notes

For best texture, shred the chicken with chunky pieces rather than fine strands, then stir thoroughly into the juices and warm for the full 10 minutes. Store leftover chicken in an airtight container in the refrigerator for up to 4 days; freeze up to 3 months (tortillas and toppings do not freeze well). For a lighter option, swap sour cream for Greek yogurt and keep the same toppings and lime.
