# 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. Roast for 25 to 30 minutes, turning once, until golden and tender.
02 - Heat 1 tablespoon olive oil in a large pot over medium heat. Add diced onion and minced garlic, sauté 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. Reduce heat and simmer for 15 to 20 minutes until vegetables are very soft.
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 parsley and a pinch of salt, then remove from heat.
05 - Use an immersion blender to purée soup until completely smooth, or transfer to a blender in batches and blend until silky.
06 - Stir in cream if using, ground nutmeg, salt, and pepper. Reheat gently if needed over low heat.
07 - Ladle soup into bowls and sprinkle generously with hazelnut crumble. Serve hot.
