Ingredients

  • 1 3-1/2 pound butternut, cut lengthwise with seeds removed
  • 2 large onions peeled and quartered
  • 1 whole garlic bulb 1/4 top cut off
  • 2 tablespoon olive oil
  • 4 cups chicken broth
  • 1 teaspoon salt
  • 1/2 teaspoon freshly ground black pepper
  • 1 cup heavy cream
  • 1 large sprig of fresh sage
  • Crunchy croutons for garnish
  • Sliced sage leaves for garnish

Instructions

  • Preheat the oven to 425°F and line a baking sheet with parchment paper.  
  • Place butternut squash on the baking sheet, cut side up, with quartered onions.  Cut 1/2-inch off the garlic, drizzle with oil wrap with foil and place on the baking sheet.  
  • Brush the squash and the onions with with olive oil, sprinkle with salt and pepper.  Transfer to the oven and roast until the vegetables are tender, about 45-50 minutes, then remove from the oven and allow to cool.
  • When the vegetables are cool enough to handle, scoop the squash into a blender and add the onion.  Unwrap the garlic and pick the cloves out with a small fork, and place into the blender.  
  • Add 2 cups of the chicken broth to the blender.  Turn the blender on to low and gradually increase the speed.  Process the vegetables to a smooth mixture, adding additional chicken broth as needed.  
  • Transfer the processed vegetables to a large soup pot or Dutch oven.  Stir in any remaining chicken broth, salt and pepper. 
  • Heat the soup on medium-high, stirring to keep from spattering and when it begins to boil, reduce the heat to low, add the cream and chopped sage, simmer for 5 minutes; then remove from the heat and ladle into soup bowls.  
  • Garnish each serving of soup with croutons and additional sliced sage leaves.    

Notes

  • It is ok for the onions and squash to have some charing as it adds a delicious smokey flavor to the soup.
  • Remove the foil packet of garlic after 30 minutes to check for doneness. If it is tender and can be removed easily with a fork it is done, if not, re-wrap and return it to the oven.
  • Do not fill the blender container past the maximum fill line. Process the soup in batches if necessary.
  • Store cooled soup in a covered container in the refrigerator for 3-4 days.  It will keep in the freezer for up to 3 months. 
  • Reheat soup on medium-low, stirring occasionally until hot.
