Chop the chicken into 1-inch chunks and set aside. Rinse and drain the white beans thoroughly to ensure they’re clean and ready.
Add the chicken, beans, diced green chilies, chopped onion, minced garlic, and toasted cumin into the crockpot. Pour over the chicken broth, making sure the ingredients are covered about two-thirds of the way.
Stir everything together with a spatula to evenly distribute the spices and ingredients. Cover the crockpot with its lid.
Set the crockpot to low and cook for 6 hours, or on high for about 3 hours, until the chicken is tender and easily shredded, and the beans are soft.
Once cooked, remove the lid and stir in the heavy cream or sour cream for added richness. Squeeze in fresh lime juice for brightness and stir to combine.
Taste the chili and adjust seasoning if needed—adding a pinch of salt or more lime juice for extra flavor. Let it sit for a few minutes to meld the flavors.
Scoop the hot chili into bowls, serve with optional toppings like shredded cheese or sour cream, and enjoy the comforting, creamy texture and fragrant aroma.
