To a large slow cooker add the frozen (or thawed) chicken breast. On top of the breasts add the onion, drained and rinsed black beans and white beans.
Add the undrained diced tomatoes with green chilies, canned corn, diced green chilies, chili powder, cumin, and ranch seasoning. Pour the chicken broth (or water is fine) overtop. Then add the cilantro. Place the cream cheese block overtop of everything.
Cook on low for 6 hours or high for 4 hours. Remove the chicken breasts to a cutting board and shred the meat with two forks. Return the chicken to the crock pot and stir the cream cheese into the mixture. Cover and let cook for an additional 10-15 minutes or until the cream cheese has fully melted and incorporated evenly.
Portion into bowls and garnish with cheese, cilantro, sour cream, avocado. We like to crush tortilla chips overtop too!
Serve immediately.
Notes
Cream cheese can be regular or reduced fat.If you want a thicker chili, reduce the amount of broth or water you add. For really thick only add ½ cup.
