I included this soup in a post last October that contained three recipes. I made this again today and tweaked it just a little. This soup is also so good I thought it deserved its own post. You can easily make this a vegetarian soup by substituting vegetable broth for the chicken broth.
Here it is:
Roasted Butternut Squash Chipotle Soup
Approximately 4 pounds of roasted butternut squash (instructions below)
Two stalks celery
One small to medium sized onions
Several cloves of garlic
4 cups chicken or vegetable broth
Olive oil (for sautéing)
Walnut oil (for roasting squash; you may use olive oil instead)
1 cup heavy cream
One canned Chipotle peppers plus a little of the adobe sauce
Roasting the Butternut Squash
Preheat oven to 375° F. Slice squash length wise in half and scoop out seeds. Rub walnut oil over cut side of squash and place face up on baking sheet. Season with kosher salt, fresh ground pepper, and fresh ground nutmeg. Roast until squash is fork tender, approximately 45-60 minutes. Remove from oven and let cool.
Making the soup
Heat two tablespoons of olive oil in large pot. Add onion, carrots, celery, garlic, and salt and sauté until soften, about 10 minutes. Scoop flesh from roasted butternut squash into pot. Add chicken broth and diced Chipotle peppers along with some adobe sauce from peppers. Bring to boil and then reduce heat and simmer for about 30 minutes stirring occasionally. Working in small batches, transfer soup to blender or food processor and purée until smooth. Return to pot, stir in cream, and serve.
