02 - 1 medium onion, diced
03 - 2 cloves garlic, minced
04 - 1 medium potato (about 5.3 oz), peeled and diced

05 - 3.75 cups vegetable broth

→ Hazelnut Crumble

11 - 2.1 oz whole hazelnuts
12 - 1 tbsp unsalted butter or olive oil for vegan
13 - 1 tbsp fresh parsley, finely chopped
14 - Pinch of sea salt

# How To Make:

01 - Preheat oven to 400°F. Spread diced celeriac on a baking sheet, drizzle with 1 tbsp olive oil, and toss to coat. Roast for 25–30 minutes, turning once, until golden and tender.
02 - Heat 1 tbsp olive oil in a large pot over medium heat. Add onion and garlic, sauté for 3–4 minutes until softened.
03 - Add roasted celeriac and diced potato to the pot. Pour in vegetable broth and bring to a boil. Reduce heat and simmer for 15–20 minutes until vegetables are very soft.
04 - Roughly chop hazelnuts. Heat butter in a small skillet over medium heat, add hazelnuts, and toast for 2–3 minutes until golden and fragrant. Stir in parsley and a pinch of salt, then remove from heat.
05 - Use an immersion blender to puree soup until completely smooth, or transfer to a blender in batches.
06 - Stir in cream if using, nutmeg, salt, and pepper. Reheat gently if needed.
07 - Ladle soup into bowls and sprinkle generously with hazelnut crumble. Serve hot.

# Expert Advice:

01 -
  • The roasted celeriac develops this incredible depth that feels almost meaty despite being completely vegetarian
  • That hazelnut crumble creates the most perfect crunch against the silky smooth soup texture
02 -
  • Roasting the celeriac instead of boiling it creates a caramelized depth that completely transforms the final flavor
  • The hazelnuts can burn quickly so keep a close eye and stir constantly during those final minutes
03 -
  • Let the soup cool slightly before blending to avoid hot splatters and dangerous pressure buildup
  • A splash of sherry vinegar added right before serving brightens everything beautifully
