When the weather cools, a bowl of hot soup is a lunch or dinner favorite. Fall and winter bring delicious squashes and hearty root vegetables in abundance. You can make a particularly tasty soup by roasting your vegetables and pureeing them with some broth to achieve the consistency you like. The quantities of the vegetables can be adjusted and even the choice of vegetables can vary. In the base recipe here, I have used butternut squash, sweet potatoes, and a yellow onion, but you can change up the taste a bit by adding garlic, carrots, other squashes, or even something more exotic such as a small beet. If you use vegetable broth and leave out the sour cream garnish, this recipe will meet the guidelines for being vegan.
  • 6 cups butternut squash cut into ~1 inch dice
  • 4 cups orange yams or sweet potatoes cut into ~1 inch dice
  • 1 large onion cut into ~1 inch dice
  • 2 to 3 tablespoons of olive oil
  • 2 14.5 ounce cans of vegetable or chicken broth
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon freshly ground nutmeg (a microplane works well for this)
  • Salt and freshly ground black pepper to taste
  • Diced red pepper for garnish (optional)
  • Celery leaves or parsley leaves for garnish (optional)
  • Light sour cream thinned with a bit of milk or water for garnish (optional)
  1. Pre-heat the oven to 450 degrees F. Line a 1/4 sheet pan or a large baking pan with aluminum foil. Place the vegetables in a large bowl and stir to mix. Drizzle with the olive oil, sprinkle with ~1 teaspoon of salt, and mix to coat all of the vegetables evenly. Pour into the lined baking pan and distribute the vegetables into an even layer. Roast in the oven for 30-40 minutes or until the vegetables are tender and are beginning to brown at the edges. Remove from the oven. At this point you can use a standard blender to puree batches of the vegetable mixture with the broth and spices or you can use an immersion blender. In either case, you transfer the mixture to a sauce pan (3 quarts or larger) so that you can heat it to serving temperature. If you would like a thinner consistency, add additional broth or water. Taste and adjust the seasoning. Pour into serving bowls and garnish with a sprig of parsley or celery leaves, diced red pepper or some sour cream. An especially attractive way to use the sour cream is to use a small spoon to distribute dots of thinned cream in a circle. Use a toothpick to drag a line connecting through the middle of all the dots to make a pretty pattern.
