Creamy Potato Leek Chives

There's something about leeks that made me fall in love with French cooking. Years ago, I burned through a whole bunch trying to make this soup too aggressively, and that's when I learned the magic word: patience. The way they soften into sweet, tender strands when you give them time over medium heat changed everything for me. Now, whenever I make this creamy potato leek soup, I'm reminded that the best dishes aren't rushed—they're built layer by layer, moment by moment.

I made this for my neighbor last winter when she was recovering from the flu, and I'll never forget how she teared up at the first taste. Something about a warm bowl of this soup on a gray afternoon just says 'I'm rooting for you.' Since then, it's become my go-to comfort gift, and honestly, it's taught me that cooking for someone isn't about impressing them—it's about showing up.

Ingredients

• Unsalted butter (2 tablespoons): This is your flavor foundation, so don't skip it or swap it for oil—it creates that rich, golden base.
• Leeks (2 large, white and light green parts): Clean them thoroughly by slicing lengthwise and rinsing between layers to catch any hidden dirt.
• Yellow onion (1 medium, chopped): Sweet and mellow when cooked low and slow, it plays backup to the stars of the show.
• Yukon Gold or Russet potatoes (700 g): Yukon Golds are naturally buttery, but Russets work beautifully too and make the soup even more velvety.
• Garlic (2 cloves, minced): One minute is all it needs—any longer and it turns bitter and grumpy.
• Vegetable stock (1 liter): Use a good quality one or homemade if you have it; it really does make a difference in the final flavor.
• Whole milk or cream (250 ml): I learned the hard way that heavy cream can be overwhelming—whole milk gives richness without dominating.
• Bay leaf (1): A gentle flavor whisper that you'll remove before blending.
• Salt and pepper: Taste as you go and season at the end when you can actually judge the seasoning properly.
• Nutmeg (pinch, optional): A tiny fleck brings out the sweetness of the potatoes in a way that feels subtle and sophisticated.
• Fresh chives (2 tablespoons): Snip them just before serving to keep their bright, oniony punch alive.

Instructions

Melt butter and soften the aromatics:

In a large pot over medium heat, let the butter get foamy and golden, then add your sliced leeks and chopped onion. Listen for that gentle sizzle—you want a soft, patient sauté here, about 6 to 8 minutes, until they're tender and translucent.

Wake up the garlic:

Add your minced garlic and let it bloom for just a minute, stirring constantly so it perfumes the whole pot without catching and turning bitter.

Build your soup base:

Toss in the diced potatoes, bay leaf, salt, pepper, and that optional pinch of nutmeg. Stir everything together to coat it in the buttery leek mixture.

Simmer until tender:

Pour in the vegetable stock and turn the heat up until it reaches a gentle boil, then lower it back down, cover the pot, and let it bubble quietly for 20 to 25 minutes. The potatoes should be so tender they practically dissolve when you press them with a spoon.

Blend into creaminess:

Fish out that bay leaf, then use an immersion blender to puree the soup directly in the pot until it's completely smooth and velvety. If using a regular blender, work in batches and be careful with the hot liquid.

Finish with cream and reheat gently:

Stir in the whole milk or cream and warm everything through over low heat—never let it come to a boil or the cream can split. Taste and adjust your salt and pepper.

Serve with grace:

Ladle into bowls and crown each one with a generous handful of fresh chives and a whisper of cream if you're feeling luxurious.

My sister once told me that the best soups are the ones that make you feel held, and that's exactly what this bowl does. There's no fanciness required—just honest ingredients and the time to let them become something greater together.

Choosing Your Potatoes

I've tested this with everything in my pantry, and the potato choice really does matter. Yukon Golds are my first choice because they're naturally waxy and buttery, almost like they were born to be soup. Russets are the reliable backup—they're starchier, so they break down into an even creamier texture that some people actually prefer. Waxy potatoes like reds will leave you with a thinner soup, so save those for a different dish. The magic is in knowing your potato and trusting it to do what it does best.

The Blending Question

Here's where I used to get stuck: should you blend it smooth or leave it chunky? I've gone both ways depending on my mood. An immersion blender lets you control exactly how smooth you go—you can keep it a little rustic if you like texture, or go completely velvety if you want restaurant-style elegance. A regular blender makes it silkier overall, but you have to work in batches and be incredibly careful with the hot liquid. I once rushed this step and got a face full of hot potato soup, which was humbling and also taught me the value of caution.

Variations and Flavor Boosters

This soup is a blank canvas in the best way. I've added crispy bacon bits, roasted garlic for sweetness, a handful of fresh tarragon, or even a swirl of truffle oil when I'm trying to impress someone. Last month I threw in some steamed broccoli at the end, and it became something entirely new. The base is so solid that you can play with it freely.

• For a vegan version, swap butter for olive oil and use oat or cashew milk instead of dairy for that same creamy texture.
• A knob of extra butter stirred in just before serving adds an almost embarrassing amount of richness.
• Croutons or crispy sage leaves on top transform this from comfort food to something you'd serve at a dinner party.
