Turn those root veggies into a powerhouse soup.
1. Slice leeks into 1-inch pieces and rinse several times under cold water, making sure grit is washed out.
2. Cook bacon with olive oil over medium heat in a soup pot. Once crisp, remove bacon; set aside. Add leeks and parsnips. Cook until soft, about 5 minutes. Add white wine, chicken broth, potatoes, bay leaves, and salt. Bring liquid to a boil, reduce heat, and simmer until potatoes are very soft, about 30 minutes.
3. Remove bay leaves. Working in small batches, process soup until it is a smooth puree. Return soup to pot and add cream; heat through.
4. Process sour cream and Blue cheese into a smooth cream. Serve soup in cups or bowls, and swirl in a tablespoon of Blue-cream mixture. Sprinkle bacon and chives on top.
