Add Ingredients to Slow Cooker: Place the chicken breasts, chopped onion, garlic, green chilies, white beans, chicken broth, cumin, oregano, garlic powder, salt, and pepper into the slow cooker.
Cook the Chili: Cover and cook on low for 6-7 hours or on high for 3-4 hours, until the chicken is fully cooked and tender.
Shred the Chicken: Once the chicken is cooked, remove it from the slow cooker, shred it using two forks, and return it to the slow cooker.
Add Cream Cheese and Sour Cream: Add the softened cream cheese and sour cream to the slow cooker, stirring until they’re melted and the chili is creamy. Let the chili cook on low for an additional 10-15 minutes to blend the flavors.
Serve and Garnish: Ladle the chili into bowls and garnish with fresh cilantro and any of your favorite toppings.
