Variations & Tips
For a spicier version, add a chopped jalapeño when you add the other vegetables. You can also substitute the chicken breasts with boneless, skinless chicken thighs for a richer flavor. If you prefer a thicker chili, you can mash some of the beans before adding them to the slow cooker. For a lighter version, use Greek yogurt instead of heavy cream.
