1. Combine Ingredients in Slow Cooker:
- Place the boneless, skinless chicken breast halves into a 3-quart slow cooker (or similar size).
- In a small bowl or measuring cup, combine the chicken broth, fresh lime juice, and chili powder. Season this mixture with salt and pepper to your taste.
- Pour the prepared broth mixture evenly over the chicken in the slow cooker.
2. Slow Cook the Chicken:
- Cover the slow cooker securely with its lid.
- Cook on the LOW setting for 2 1/2 to 3 hours. The chicken is done when it is very tender and an instant-read thermometer inserted into the thickest part reads 165°F (74°C). (Note: 2.5-3 hours on LOW for whole chicken breasts is a relatively short slow cooker time; ensure they are truly tender enough to shred. If using larger/thicker breasts, or if your slow cooker runs cooler, it might take up to 4-5 hours on LOW or 2-3 hours on HIGH).
3. Shred Chicken and Add Zest:
- Once the chicken is cooked and tender, carefully remove the chicken breasts from the slow cooker and place them on a clean cutting board or large plate. Leave the cooking liquid in the slow cooker.
- When the chicken is cool enough to handle, use two forks to shred the meat.
- Return the shredded chicken to the slow cooker with the cooking juices.
- Stir in the 1 teaspoon of grated lime zest.
4. Serve:
- Stir the chicken and zest well to combine with the juices. Let it heat through for a few more minutes on WARM or LOW if needed.
- Serve the Spicy Lime Chicken hot. It’s delicious served over hot cooked rice, used as a filling for tacos or burrito bowls, or on salads.
- Garnish with fresh cilantro leaves, if desired, and offer extra lime wedges, avocado, chopped tomato, or sliced green onions on the side.
