Potato leek soup, or vichyssoise when served cold, is French simplicity at its finest. Tender leeks and potatoes simmer together until soft, then blend into an impossibly smooth puree that tastes far more refined than its humble ingredients suggest.
This is a soup that celebrates restraint — just a few ingredients, handled well, produce something truly elegant. A swirl of cream and a sprinkle of chives are all the adornment it needs.
French cooking teaches us that mastering a few fundamental techniques transforms ordinary ingredients into extraordinary meals. Potato Leek Soup draws on that tradition, using precise methods to develop deep, complex flavors from accessible ingredients. The result is a dish that feels special without being fussy.
The key to nailing this dish is proper heat management and timing. Start with your protein at room temperature, season generously at every stage, and resist the urge to rush. Let each component develop its flavor fully before moving to the next step — patience here pays off enormously in the final result.
Ingredients
- 3 large leeks, white and light green parts, sliced
- 4 medium Yukon Gold potatoes, peeled and cubed
- 5 cups vegetable or chicken broth
- 1/2 cup heavy cream
- 3 tbsp butter
- Fresh chives for garnish
Instructions
- 1
Melt butter in a large pot over medium-low heat. Add sliced leeks and cook gently until very soft, about 10 minutes, without browning.
- 2
Add cubed potatoes and broth. Bring to a boil, then reduce heat and simmer until potatoes are very tender, about 20 minutes.
- 3
Blend until completely smooth using an immersion blender or in batches in a countertop blender.
- 4
Stir in heavy cream and season with salt and white pepper. Warm through gently.
- 5
Serve hot garnished with snipped chives, or chill thoroughly and serve cold as vichyssoise.

Tips & Storage
Pro Tips
Wash leeks thoroughly — soil hides between the layers. Slice, then soak in water to rinse.
Use white pepper instead of black for a cleaner look.
For a lighter version, skip the cream and add a drizzle of truffle oil instead.
Let meat rest for at least 5 minutes after cooking. This allows the juices to redistribute evenly for maximum tenderness.
Storage
Store leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze individual portions in freezer-safe containers for up to 3 months. Label with the date and recipe name.
Reheating
Reheat gently on the stovetop. Add broth to adjust consistency.

Editor's Note
Editor's note: We tested this with both bone-in and boneless cuts and both work well. Bone-in takes a bit longer but rewards you with richer, more flavorful results.

Frequently Asked Questions
- What is vichyssoise?
- Vichyssoise is simply potato leek soup served cold, typically with extra cream.
- Can I use russet potatoes?
- Yes, though they yield a starchier, less silky result. Yukon Gold is preferred.
- Can I make this ahead of time?
- Yes — prepare up to the final cooking step, refrigerate, then finish cooking when ready to serve. Most dishes actually benefit from a rest in the fridge as the flavors have time to meld.
- How do I know when it is done?
- The most reliable method is an instant-read thermometer. For chicken, look for 165°F internal. For beef, 130°F for medium-rare, 140°F for medium. For pork, 145°F. Visual cues include clear juices and firm-to-the-touch texture.
