Add chicken broth, white beans, green chiles, garlic, onion, cumin, oregano, salt, and cayenne pepper.
Mix everything well.
Cover the slow cooker and cook on low for 4–6 hours or high for 2–4 hours until the chicken is fully cooked.
Transfer the chicken to a plate and allow it to cool slightly.
Shred the chicken using two forks.
Use an immersion blender to blend part of the chili in the slow cooker to create a creamy texture, leaving some beans intact.
Alternatively, blend a few ladles of chili in a blender or food processor, then return it to the pot.
Add the shredded chicken back into the slow cooker and stir it into the chili.
Mix in freshly chopped cilantro for a burst of flavor.
Serve the chili in bowls with a squeeze of lime juice and your favorite toppings.
