Celeriac With Hazelnut Crumble (Printable)

Velvety roasted celeriac blended to silky smoothness, finished with crunchy toasted hazelnut topping for added texture.

# What You’ll Need:

→ Vegetables

01 - 1 large celeriac (about 1.5 lbs), peeled and diced
02 - 1 medium onion, diced
03 - 2 cloves garlic, minced
04 - 1 medium potato (about 5.3 oz), peeled and diced

→ Liquids

05 - 3.75 cups vegetable broth
06 - 2 tbsp olive oil
07 - 3.4 fl oz heavy cream (optional, or use plant-based cream for vegan)

→ Seasonings

08 - 1 tsp sea salt, or to taste
09 - 1/2 tsp black pepper, freshly ground
10 - 1/4 tsp ground nutmeg

→ 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

# Directions:

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 diced onion and minced 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 chopped parsley and a pinch of salt, then remove from heat.
05 - Use an immersion blender to puree soup until completely smooth. Alternatively, transfer to a stand blender in batches and blend until smooth.
06 - Stir in heavy cream (if using), ground nutmeg, salt, and black pepper. Reheat gently over low heat if needed.
07 - Ladle soup into bowls and sprinkle generously with hazelnut crumble. Serve hot.

# Expert Tips:

01 -
  • The roasting process brings out a subtle sweetness in the celeriac that you simply cant achieve by boiling alone.
  • That moment when the hazelnut crumble hits the creamy soup creates this beautiful temperature and texture contrast that makes each spoonful an adventure.
02 -
  • I once skipped roasting the celeriac to save time and ended up with a completely different soup lacking that deep, caramelized complexity.
  • The soup will thicken considerably as it sits, so dont worry if it seems a bit thin right after blending.
03 -
  • Let the soup cool slightly before blending to prevent steam pressure from causing hot splashes, a lesson I learned the hard way with a kitchen ceiling that never quite recovered.
  • Reserve a few tablespoons of the roasted celeriac before blending and add them back as a garnish for textural contrast that hints at whats to come.
