This is the kind of soup that feels calm from the first step.
Leeks cook slowly until they soften into something naturally sweet, the base stays light, and the toppings bring contrast right at the end. It’s simple, but very intentional.

Ingredients
Why This Stays Light
From experience, leek soup becomes heavy only when rushed.
Slow cooking draws out their natural sweetness without needing extra ingredients. The cream softens the texture, but the real balance comes from the toppings — smoked salmon and lovage oil keep it fresh and layered.
Instructions
- Start with the leeks.
- Slice them lengthwise, then into half-moons, and rinse well to remove any grit.
- Warm the olive oil and butter in a wide pot.
- Add the chopped onion and cook gently until soft, not coloured.
- Add the leeks and garlic.
- Season lightly with salt and let everything cook slowly, stirring from time to time, until the leeks collapse and turn glossy.
- Pour in the stock.
- Bring to a gentle simmer and cook for about 20 minutes, until the leeks are completely tender.
- Blend the soup until smooth.
- Stir in the cream, taste, and adjust seasoning with salt and pepper. Keep warm.
- Make the lovage oil.
- Blend the lovage leaves with the olive oil until bright green and aromatic. Set aside.
- Slice the smoked salmon into small ribbons.
- Crumble the curd cheese loosely with your fingers.
- Serve the soup hot.
- Top each bowl with salmon, curd cheese, and a few drops of lovage oil.
Texture & Flavor Notes
The soup should be smooth and silky, not heavy.
Leeks bring gentle sweetness, while smoked salmon adds saltiness and depth. The curd cheese softens everything, and lovage oil adds a fresh, herbal lift.
Pairing Ideas
- dark rye bread for a deeper flavor contrast
- sourdough for something lighter
- soft-boiled egg on the side for a more filling meal
Tips for Best Results
- Wash leeks thoroughly — grit can ruin the texture
- Cook leeks slowly for better sweetness
- Blend longer for a smoother finish
- Add toppings just before serving
Small detail that helps: if the soup feels too thick, add a splash of warm stock to loosen it without diluting flavor.
Storage & Reheating
- Store the soup (without toppings) in the fridge for up to 3 days
- Reheat gently over low heat — avoid boiling
- Add toppings fresh when serving
From experience, the soup base improves slightly the next day as flavors settle.
Common Mistakes to Avoid
- Not washing leeks properly → gritty texture
- Cooking on too high heat → dull flavor
- Overboiling after adding cream → less smooth texture
- Adding toppings too early → loss of contrast
FAQ
Can I make this soup without cream?
Yes, but it will be lighter and less silky. You can add a bit more stock or a splash of milk instead.
What can I use instead of lovage?
Parsley or dill works well, though the flavor will be slightly different.
Can I freeze this soup?
Yes, but freeze without cream for best results. Add it after reheating.
Is smoked salmon necessary?
No, but it adds depth. You can skip it or replace with something mild like cooked fish or keep it vegetarian.
