# What You'll Need:
→ Vegetables
01 - 1 large celeriac (approximately 1.5 lbs), peeled and diced
02 - 1 medium onion, diced
03 - 2 cloves garlic, minced
04 - 1 medium potato (approximately 5.3 oz), peeled and diced
→ Liquids
05 - 3.75 cups vegetable broth
06 - 2 tablespoons olive oil
07 - 3.4 fl oz heavy cream, optional, or plant-based cream for vegan
→ Seasonings
08 - 1 teaspoon sea salt, or to taste
09 - 0.5 teaspoon black pepper, freshly ground
10 - 0.25 teaspoon ground nutmeg
→ Hazelnut Crumble
11 - 2.1 oz whole hazelnuts
12 - 1 tablespoon unsalted butter, or olive oil for vegan
13 - 1 tablespoon fresh parsley, finely chopped
14 - Pinch of sea salt
# How To Make It:
01 - Preheat oven to 400°F. Spread diced celeriac on a baking sheet, drizzle with 1 tablespoon olive oil, and toss to coat evenly. Roast for 25 to 30 minutes, turning once halfway through, until golden and tender.
02 - While celeriac roasts, heat 1 tablespoon olive oil in a large pot over medium heat. Add diced onion and minced garlic, sautéing for 3 to 4 minutes until softened and fragrant.
03 - Add roasted celeriac and diced potato to the pot. Pour in vegetable broth and bring to a boil over high heat. Reduce heat to medium-low and simmer for 15 to 20 minutes until vegetables are very soft and easily pierced with a fork.
04 - While soup simmers, roughly chop hazelnuts. Heat butter in a small skillet over medium heat, add hazelnuts, and toast for 2 to 3 minutes until golden and fragrant. Stir in finely chopped parsley and a pinch of salt, then remove from heat.
05 - Once vegetables are completely tender, use an immersion blender to purée soup until completely smooth. Alternatively, carefully transfer soup in batches to a stand blender and blend until silky.
06 - Stir in cream if using, ground nutmeg, sea salt, and black pepper. Reheat gently over medium-low heat until steaming, stirring occasionally to ensure even seasoning.
07 - Ladle soup into serving bowls and sprinkle generously with toasted hazelnut crumble. Serve immediately while hot.
