Ingredients
              3 tablespoons olive oil,
              divided
              1 medium butternut squash, halved lengthwise, seeds discarded,
              washed, and reserved
              Salt and freshly ground black pepper
              1 medium onion, chopped
              2 stalks celery, chopped
              2 carrots, chopped
              2 garlic cloves, minced
              6 cups chicken broth, divided
              2 teaspoons minced canned chipotle chiles in adobo
              Chipotle Cream:
              1 teaspoon minced canned
              chipotle chiles in adobo
              1/2 cup sour cream
              Salt and freshly ground black pepper
              Directions
              Preheat the oven to 400
              degrees F.
              Using 1 tablespoon of
              the olive oil, grease the sliced surface of the squash and season
              with salt and pepper, to taste. Arrange on a baking sheet and
              roast until very tender, about 45 minutes. Remove from the oven
              and let cool.
              In a large heavy pot
              over medium-high heat, add the remaining olive oil, onion, celery,
              and carrot, then season with a pinch of salt. Saute until just
              tender, about 10 minutes. Add the garlic and saute for 2 minutes.
              Scoop the butternut squash flesh into the pot and stir. Add 4
              cups of the chicken broth and bring to a boil. Reduce the heat
              to low, cover the pot, and simmer until the vegetables are very
              tender, about 30 minutes.
              Turn off the heat and
              using an immersion blender, carefully puree the soup until very
              smooth. If necessary, add more of the remaining stock to create
              desired consistency. Mix in 2 teaspoons of the chipotle into
              the soup, and season with salt and pepper, to taste.
              In a small bowl, mix
              together 1 teaspoon of chipotle and the sour cream. Season the
              chipotle cream with salt and pepper, to taste. Transfer the soup
              to bowls. Top each with a dollop of chipotle cream and serve.
