Add coconut oil to a stock pot and melt over medium heat.
Cook the chicken in coconut oil until cooked through and juices run clear.
Add the chicken broth, coconut milk, and curry powder. Stir to combine. Reduce the heat to medium-low and cook while occasionally stirring until soup comes to a low boil. Reduce heat to low and simmer for 15 minutes.
Add the cauliflower rice and cook for 5 minutes or until the rice is tender.
