How to Make It
Melt butter in a medium-size Dutch oven over medium heat. Tie thyme sprigs together with kitchen string. Add parsnips, next 6 ingredients, and thyme to Dutch oven, and cook, stirring often, 10 minutes. Stir in broth and 2 cups water, and bring to a boil. Reduce heat to medium-low; cover and simmer 15 minutes.
Discard thyme. Process parsnip mixture, in batches, in a blender or food processor until smooth, stopping to scrape down sides as needed. Return mixture to Dutch oven, and stir in heavy cream.
Cook over medium heat, stirring often, 5 minutes or until hot. Serve immediately.
