# What You'll Need:

→ Vegetables

01 - 1 large celeriac (about 1.5 lbs), peeled and cubed
02 - 1 medium onion, chopped
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

→ Dairy

07 - 3.4 fl oz heavy cream or plant-based alternative

→ Spices & Seasoning

08 - 0.5 tsp ground white pepper
09 - Salt, to taste

→ Hazelnut Crumble

10 - 2.5 oz whole hazelnuts, roughly chopped
11 - 1 tbsp unsalted butter or plant-based margarine
12 - 0.25 tsp sea salt
13 - 1 tbsp fresh parsley, finely chopped (optional garnish)

# Directions:

01 - Preheat the oven to 390°F.
02 - Toss celeriac cubes with 1 tbsp olive oil, salt, and pepper. Spread on a baking tray and roast for 25-30 minutes, turning halfway through, until soft and golden.
03 - While celeriac roasts, heat 1 tbsp olive oil in a large pot over medium heat. Sauté onion for 4 minutes until translucent. Add garlic and potato; cook for another 2 minutes.
04 - Transfer roasted celeriac to the pot. Add vegetable broth and bring to a gentle boil. Simmer for 15-20 minutes until vegetables are very soft.
05 - Toast hazelnuts in a dry skillet over medium heat for 3-4 minutes until fragrant. Add butter and sea salt, stirring until nuts are golden and coated. Remove from heat and cool slightly.
06 - Use an immersion blender to purée the soup until silky smooth. Stir in cream if using. Taste and adjust seasoning with salt and pepper.
07 - Ladle soup into bowls. Top generously with hazelnut crumble and chopped parsley.

# Expert Tips:

01 -
  • The roasting process creates a rich, complex flavor profile that boiling alone cannot achieve.
  • It is naturally gluten-free and easily made vegan with simple substitutions.
  • The hazelnut crumble adds a gourmet touch and satisfying crunch.
02 -
  • Always roast the celeriac until golden; those caramelized edges are where the deep flavor lives.
  • When using a countertop blender for hot liquids, never fill it more than halfway and hold the lid down with a kitchen towel.
  • Toast the hazelnuts carefully as they can go from golden to burnt very quickly.
