In a skillet, fry the bacon and onion until golden brown, and then drain. Alternately, if you have a slow cooker that has a sauté feature, fry the bacon right in the slow cooker, then drain some of the fat.
Add the bacon and onion to a 6-quart slow cooker with the finely-chopped clams. Make sure you pour the retained liquid from the clams in there, too.
Add the jicama pieces and chicken bone broth.
Season with salt and pepper to taste.
Cover, and cook on low for 3–4 hours, or until the vegetables are tender. (If you prefer a thicker soup, you can purée part of it including the broth and jicama pieces, then return to the slow cooker.)
In the last 20 minutes, add the coconut cream, stir to blend. Taste and season by adding more salt and pepper as needed.
Top each serving with a sprinkling of chopped fresh parsley, and enjoy!
