Gluten Free Leek & Butternut Squash Soup
Ingredients
- 4 tablespoons unsalted butter
- ½ medium yellow onion, finely diced
- 2 large leeks, white and light green parts only, thinly sliced
- 1 teaspoon kosher or fine sea salt, plus more to taste
- 4 large garlic cloves, finely minced
- 2 teaspoons finely chopped fresh thyme, 3-4 sprigs
- 2 pounds butternut squash, peeled and chopped
- 4 cups low-sodium chicken or vegetable broth
- 1 teaspoon Champagne vinegar
- 1 teaspoon freshly ground black pepper
- ¼ cup crème fraiche, for garnish
- 2 tablespoons chopped fresh chives, for garnish
Instructions
- Heat the butter in a large soup pot over medium-low heat until it just begins to melt and bubble slightly. Add the onion, leeks, and a pinch of salt. Cover and sauté over medium-low heat for 8 minutes, stirring once, until soft and translucent. Add garlic and thyme, and sauté, uncovered, for another 2 minutes.
- Add butternut squash and sauté for 3-5 minutes. Add chicken broth and bring to a boil. Reduce heat to low and simmer, uncovered, for 20-30 minutes.
- Place an immersion blender in the pan and carefully blend the soup until very smooth (alternatively, you can carefully transfer the soup to a blender and puree until smooth). Once the soup is the right consistency, add the champagne vinegar (this brightens the flavor) and bring back to a simmer for another 10-15 minutes, or until it has thickened slightly. Season with salt and pepper. At this point, you can let the soup cool slightly, then refrigerate for up to 8 hours until ready to reheat and serve.
- Spoon the soup into serving bowls with 1-2 teaspoons of crème fraiche on top and sprinkle with fresh chives.
