- prep · ~5 min
Clean and slice the leeks.
Trim the dark green tops and root ends from the leeks. Slice the white and light green parts in half lengthwise, rinse thoroughly under running water to remove all grit between layers, then slice into thin half-moons.
TIPLeeks hide dirt between layers — fan out the slices in a bowl of water, swish, then lift them out so grit settles to the bottom. - saute · ~11 min
Sauté the leeks and garlic in butter.
1.Melt the butter in a large pot over medium heat.2.Add the sliced leeks and cook gently, stirring occasionally, until softened but not browned (8-10 min).3.Add the minced garlic and cook until fragrant (1 min).TIPKeep the heat medium-low — you want the leeks to sweat and release their sweetness without taking on any color. - boil · ~25 min
Add potatoes and water, then simmer.
1.Add the cubed potatoes to the pot.2.Pour in the water and add the salt.3.Bring to a boil, then reduce heat to low, cover, and simmer until potatoes are fork-tender (20-25 min).TIPCut potatoes into even, bite-sized cubes so they cook uniformly and blend smoothly. - mix · ~2 min
Blend the soup until silky smooth.
Remove the pot from heat. Use an immersion blender directly in the pot and purée until completely smooth and velvety. If using a countertop blender, work in batches and vent the lid slightly to release steam.
TIPFor the silkiest texture, blend a full minute longer than you think — it transforms the soup from good to restaurant-quality. - mix · ~1 min
Adjust seasoning and consistency.
If the soup is too thick, stir in a splash of water until it reaches your desired consistency. Taste and add the black pepper, adjusting salt if needed.

Ladle into bowls and finish with cream, chives, and a crack of black pepper.
Serve hot. Drizzle each bowl with cream, scatter fresh chives on top, and finish with a grind of black pepper.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Leeks trap grit between layers—after slicing, soak them in a bowl of water and lift out gently so dirt sinks to the bottom.
- 2Sweat the leeks on medium-low heat until fully tender but not browned; this draws out their natural sweetness without bitterness.
- 3Cut potatoes into uniform 1-inch cubes so they cook evenly and blend into a perfectly smooth puree.
- 4Blend the soup for at least a full minute after it looks smooth to achieve a velvety, restaurant-style texture.
- 5This soup thickens as it sits—thin it with a splash of water or broth when reheating to restore the desired consistency.
- 6For make-ahead, cool completely and refrigerate up to 3 days; reheat gently on the stove, stirring often.
Adapt it for your goals.
