'Tis the season for squash and soup! This is the kind of soup that I love to order at restaurants, smooth and delicious, highlightling the crops of the season.
The good news is that it is easy enough to make at home; save your restaurant bucks for the Christmas shopping budget 🙂
Roasting squash and sweet potatoes take little effort and it can be done ahead of time to save time on soup day. I prefer roasting to steaming or boiling because it concentrates and deepens the flavor of the vegetables.
Oven-Roasted Butternut Squash Soup
This vegetarian soup pairs savory winter squash and sweet apples to create a creamy soup that is sure to please everyone at the table. This fall classic is perfect on its own or served alongside a grilled cheese sandwich.
1 medium butternut squash
1 sweet potato, about 1 lb.
2 Tbsp. butter or olive oil
1 medium onion finely chopped
1 celery stalk, finely chopped
1 carrot, peeled and finely chopped
1 large apple, peeled and chopped
1 tsp. kosher salt
1/2 tsp. ground coriander
1/4 tsp. ground allspice
1/4 tsp. ground black pepper
1/4 tsp. ground cinnamon
1/4 tsp. paprika
pinch of cayenne
5 cups vegetable broth, divided
2 Tbsp. honey, agave or brown sugar
2 Tbsp. molasses
2 tsp. cider vinegar or 1 Tbsp. lemon juice
1/4 cup heavy cream (optional)
finely chopped fresh cilantro or fresh parsley
Preheat oven to 350°F. Cut squash in half lengthwise with a strong knife and a strong arm. Scoop out the seeds with a spoon and discard. Prick the sweet potato with a fork. Place the sweet potato and squash, skin side up, onto a baking sheet.
Roast for 1 hour or until very tender, depending on the size of the squash, it make take 15-20 minutes more. When cool enough to touch, scoop cooked squash out of the skin and transfer to a food processor.
Slice the sweet potato lengthwise and scoop the sweet potato away from the skin. Add it to the food processor with 1 cup of broth and puree until very smooth. This step can be done one day ahead and puree can be refrigerated until needed to prepare the soup.
While the squash roasts, you can prepare the soup base. Add the butter to large pot over medium heat. When melted, add the next 11 ingredients to the pot (onion through cayenne).
Cook and stir until onions begin to soften, about 5 minutes. Add 1 cup of broth to the vegetables and stir well. Cover and simmer until carrots and celery are tender, about 10 minutes.
Use a slotted spoon to transfer the vegetables to a food processor. Add 1 cup of broth to the processor and puree until smooth. Add it back to the pot along with the pureed squash and whisk until smooth. Alternatively, process the soup with a hand held blender.
Stir in the remaining 3 cups of broth, honey, molasses and cider vinegar. Bring to a gentle simmer over medium heat. Reduce heat to low, stir in the cream, if using, and cook for 10 minutes uncovered. Garnish each bowl with a sprinkling of cilantro or parsley.
