1. Heat olive oil in a Dutch oven over medium heat. Add onion; cook 5 minutes or until tender, stirring frequently. Add apple and the next 4 ingredients (through garlic); cook 1 minute, stirring constantly. Add parsnip, chicken broth, and apple cider; bring to a boil. Cover, reduce heat, and simmer for 30 minutes or until parsnip is tender.
2. Place half of parsnip mixture in a blender. Remove center piece of blender lid (to allow steam to escape); secure blender lid on blender. Place a clean towel over opening in blender lid (to avoid splatters). Blend until smooth. Pour into a large bowl. Repeat the procedure with remaining parsnip mixture. Stir in salt and pepper. Ladle about 3/4 cup soup into each of 8 bowls; top each serving with 1 teaspoon crème fraîche.
