Palsternackssoppa med Brynt Smör

Palsternackssoppa is a refined yet simple Swedish winter soup that celebrates the parsnip — a root vegetable long beloved in Scandinavian cooking. Finished with nutty brown butter and crushed hazelnuts, this silky potage transforms an overlooked vegetable into an elegant dinner-party first course.

Serves: 4

Ingredients

• 3 tbsp (45ml) unsalted butter, divided
• 1 large onion, roughly chopped
• 2 cloves garlic, sliced
• 700g (1.5 lb) parsnips, peeled and roughly chopped
• 150g (5 oz) floury potato (e.g. King Edward), peeled and cubed
• 900ml (3¾ cups) vegetable stock
• 100ml (scant ½ cup) single cream
• 1 tsp (5ml) fine salt
• ½ tsp (2ml) white pepper
• ¼ tsp (1ml) ground nutmeg
• 1 tsp (5ml) fresh thyme leaves

Brown butter garnish:

• 40g (1.5 oz) unsalted butter
• 40g (1.5 oz) blanched hazelnuts, roughly crushed
• Fresh thyme sprigs

Instructions

1. Melt 2 tbsp butter in a large saucepan over medium heat. Add onion and cook, stirring occasionally, for 7–8 minutes until golden and soft. Add garlic and thyme and cook 1 minute more.
2. Add parsnips and potato. Pour in the stock and season with salt, pepper, and nutmeg. Bring to a boil, then reduce heat and simmer, partially covered, for 20 minutes until vegetables are completely tender.
3. Blend with a stick blender until completely smooth. Pass through a fine sieve for extra silkiness if desired. Stir in cream. Return to low heat and keep warm.
4. For the brown butter, place butter in a small light-coloured saucepan over medium heat. Cook, swirling often, for 4–5 minutes until the milk solids turn golden brown and smell nutty. Add crushed hazelnuts and fry 1 minute.
5. Ladle soup into warm bowls. Drizzle generously with the hazelnut brown butter. Garnish with fresh thyme and serve immediately.

Cook's Notes: The potato adds body and helps the soup blend to a silkier consistency than parsnip alone. Brown butter goes from perfect to burnt quickly — use a light-coloured pan and never walk away. This soup is equally good served the next day; thin with a little stock when reheating.
