Add Ingredients to Your Crockpot: Put the chicken breasts in the bottom of your crockpot. Add the drained white beans, corn, diced green chilies, minced garlic, and chopped onion on top of the chicken. Pour in the chicken broth and sprinkle with cumin, chili powder, oregano, salt, and black pepper evenly over everything.
Slow Cook the Chili: Cover and cook on low for 6 to 8 hours or on high for 3 to 4 hours until the chicken is fully cooked and tender.
Shred the Chicken and Make It Creamy: Remove the chicken breasts, shred them using two forks, then put the shredded chicken back into the crockpot. Add the cream cheese cubes, stirring until they melt and blend into the chili. Next, stir in the sour cream until the chili is smooth and creamy. Taste and add more salt or pepper if you like.
Serve and Garnish: Ladle the chili into bowls. Top each with chopped fresh cilantro, diced avocado, shredded cheese, and a dollop of sour cream. Serve with lime wedges on the side for an extra bright flavor boost if desired.
