Place the chicken breasts at the bottom of the crockpot.
- Add the white beans, diced green chilies, chopped onion, minced garlic, cumin, chili powder, coriander, paprika, oregano, salt, and pepper into the crockpot.
- Pour the chicken broth over the ingredients, ensuring everything is covered.
- Cover the crockpot and cook on low for 6-7 hours, or on high for 3-4 hours, until the chicken is fully cooked and easily shreds with a fork.
- Remove the chicken from the crockpot and shred it using two forks. Return the shredded chicken to the crockpot.
- Add the frozen corn (if using) and lime juice to the chili, stirring to combine. Let it cook for an additional 10-15 minutes, until the corn is heated through.
- For extra creaminess, stir in the sour cream or Greek yogurt just before serving.
- Serve the chili hot, garnished with fresh cilantro and shredded cheese, if desired.
