Equipment

Ingredients

  • 2 large kohlrabi bulbs peeled and chopped
  • 3 medium parsnips peeled and sliced
  • 2 medium turnips peeled and chopped
  • 4 cloves garlic whole
  • 2 tablespoons olive oil for roasting and sautéing
  • 4 cups vegetable broth preferably low sodium
  • 1 teaspoon fresh thyme chopped
  • to taste salt and pepper
  • 1/4 cup heavy cream optional, for richness

Instructions

  • Preheat your oven to 400°F (200°C). Spread peeled and chopped root vegetables and whole garlic cloves on a baking sheet. Drizzle with olive oil, toss to coat, and roast in the oven for about 30-40 minutes until tender and caramelized, filling your kitchen with a warm, earthy aroma.
  • While the vegetables roast, heat a tablespoon of olive oil in a large pot over medium heat. Add chopped thyme and sauté for about 30 seconds until fragrant, then remove from heat.
  • Once the roasted vegetables are cool enough to handle, transfer them to the pot. Pour in the vegetable broth and bring to a gentle simmer over medium heat, allowing the flavors to meld for about 10 minutes.
  • Use an immersion blender or transfer the soup in batches to a blender. Puree until smooth and creamy, creating a velvety texture that coats the back of a spoon.
  • Return the pureed soup to the pot if needed, and stir in a splash of heavy cream for extra richness. Season with salt and freshly ground pepper to taste. Warm through for another few minutes until heated evenly.
  • Taste the soup and adjust seasoning if necessary. Ladle into bowls, garnish with a sprig of thyme if desired, and serve hot for a cozy, comforting meal.

Notes

For an extra velvety texture, pass the soup through a fine sieve after blending. Feel free to top with toasted breadcrumbs or a drizzle of olive oil for added presentation.
