Place the chicken breasts, chopped onion, cannellini beans, great northern beans, diced green chilies, diced tomatoes and green chilies, chicken broth, cumin, oregano, garlic powder, pepper, and salt into the basin of your slow cooker.
Stir all ingredients together until combined.
Cover the slow cooker and cook on LOW for 6 to 8 hours or on HIGH for 3 to 4 hours, until the chicken is cooked through and easily shredded.
Remove the chicken from the slow cooker and place it on a cutting board. Use two forks to shred the chicken completely. Return the shredded chicken to the slow cooker.
Add the cubed cream cheese and heavy cream to the chili. Stir gently until the cream cheese has melted completely and the chili is creamy.
Taste the chili and adjust salt and pepper as needed.
Serve hot with your favorite toppings like shredded cheese, a dollop of sour cream, and fresh cilantro.
Notes
For a thicker chili, remove about 1 cup of the liquid and beans before shredding the chicken, mash them together, and stir the mixture back into the slow cooker.
If you prefer a spicier chili, add 1/4 teaspoon of cayenne pepper with the other spices.
This recipe works well using pre-cooked rotisserie chicken; add it during the last 30 minutes of cooking time along with the cream cheese.
