Combine the cooked beef, vegetables, seasonings, and broth in the bowl of a 6-quart slow cooker. Stir gently to combine. Cover, and cook on low for 8 hours.
Whisk together the arrowroot starch and coconut cream until smooth.
When the soup is done, pour the arrowroot mixture into the slow cooker, and stir to combine. Cover, and continue cooking for an additional 30 minutes to thicken.
Serve warm with chopped green onions, coconut yogurt, and cilantro. Enjoy!
