Ingredients Equipment Method Notes

Ingredients
  

  • 2 large kohlrabi peeled and chopped
  • 2 large parsnips peeled and chopped
  • 1 large sweet potato peeled and chopped
  • 2 tablespoons olive oil
  • 1 cup apple cider for finishing
  • 8 leaves sage fresh, for crispy leaves
  • 2 cloves garlic minced
  • 1 small onion chopped
  • 4 cups vegetable broth
  • salt to taste
  • pepper to taste

Equipment

  • Baking sheet
  • Blender
  • Large pot
  • Sauté pan

Method
 

  1. Preheat the oven to 400°F (200°C). Spread chopped kohlrabi, parsnips, and sweet potato on a baking sheet. Drizzle with olive oil and toss to coat evenly.
  2. Roast the vegetables in the oven for about 35-40 minutes, until they are deeply browned and caramelized around the edges, filling the kitchen with a sweet aroma.
  3. While the vegetables roast, add a splash of olive oil to a large pot over medium heat. Sauté chopped onion and minced garlic until fragrant and translucent, about 5 minutes.
  4. Add the roasted vegetables to the pot and pour in the vegetable broth. Bring the mixture to a simmer and cook for another 10 minutes to meld the flavors.
  5. Use an immersion blender or transfer the mixture to a blender and puree until smooth and velvety.
  6. Pour the soup back into the pot, stir in the apple cider, and season with salt and pepper to taste. Warm gently over low heat for a few minutes.
  7. Meanwhile, crisp the sage leaves in a small sauté pan over medium heat until they turn dark green and become fragrant, about 1-2 minutes. Remove and set aside.
  8. Once the soup is heated through, ladle it into bowls and garnish with the crispy sage leaves for added texture and flavor.
  9. Serve the soup hot, enjoying the smooth, roasted flavors accented by the crispy sage and a splash of apple cider for brightness.

Notes

You can prepare the roasted vegetables a day ahead to save time. For an extra depth of flavor, add a splash of cream or a swirl of olive oil just before serving.
