Creamy Potato Leek Chives

There's something about leeks that stops me mid-chop—their pale layers like concentric rings of sweetness. A friend once brought a pot of this soup to my apartment on a gray November afternoon, and I watched the kitchen fill with steam as she stirred, the butter and leeks creating something almost golden. I've been making it ever since, usually on nights when the world feels a bit too loud and I need something honest and warm to come home to.

I made this for a dinner party once when I was nervous about cooking for people I wanted to impress. The soup turned silky and pale green-gold, and someone said it tasted like I'd been making it my whole life. That's when I realized good cooking isn't about technique alone—it's about caring enough to let simple ingredients speak for themselves.

Ingredients

• Leeks (3 large, white and light green parts): These are gentler and sweeter than onions—the soul of the soup really—so take time to rinse them well between layers where soil hides.
• Yukon Gold potatoes (4 medium, peeled and diced): They have a waxy texture that breaks down into creaminess without turning grainy, but russets work if that's what you have.
• Onion (1 medium, diced): Just a supporting player to deepen the flavor without overpowering the leeks' delicate sweetness.
• Garlic (2 cloves, minced): Added after the leeks soften so it doesn't burn and turn bitter—timing matters here.
• Vegetable broth (4 cups): Use something you'd actually drink on its own; a good broth lifts the whole soup.
• Whole milk or heavy cream (1 cup): Heavy cream gives richness, but milk keeps it lighter—either creates that velvety finish.
• Unsalted butter (2 tablespoons): The foundation that lets everything bloom together in the pot.
• Salt and black pepper: Taste as you go; the broth's saltiness varies, so you'll likely need less than the full teaspoon.
• Bay leaf (1): A quiet flavor builder that should come out before blending so no one bites into it.
• Fresh chives (2 tablespoons, finely chopped): The final whisper of freshness that reminds you this soup is alive.

Instructions

Melt and soften:

Melt butter over medium heat and add your sliced leeks and diced onion. Stir occasionally for about 5 minutes—you want them soft and translucent, not golden or crispy, so listen for a gentle sizzle and watch the color deepen.

Awaken the garlic:

Add minced garlic and cook for just 1 minute until the smell fills your kitchen—that's your signal it's fragrant but not burned. If you wait too long it will taste acrid.

Build the base:

Add diced potatoes, salt, pepper, and the bay leaf, stirring everything together so the potatoes get coated in the buttery leek mixture. This takes less than a minute.

Simmer to tenderness:

Pour in your broth, bring it to a boil, then lower the heat and let it bubble gently for 20 to 25 minutes until the potatoes break apart when you press them with a spoon. You'll know it's ready when there's no resistance.

Remove and blend:

Fish out the bay leaf carefully, then use an immersion blender to puree until the soup is completely smooth—this is deeply satisfying, watching the chunks disappear into velvet. If you don't have an immersion blender, work in batches with a standard blender, letting it cool slightly first.

Finish with cream:

Stir in your milk or cream and warm it through gently over medium-low heat so nothing breaks or curdles. Taste and adjust salt and pepper now—the final seasoning always tastes different than when you started.

Serve and garnish:

Ladle into bowls and scatter the fresh chives across the top, letting them float on the surface. The green against the cream is beautiful, and it tastes like the very moment the soup is ready to eat.

Pin It

I remember my mother ladling this into bowls for us when my sister came home after a long semester away. No one talked much, but the spoons clinked softly, and there was something about the warmth and simplicity that said everything that needed saying. Food like this belongs in moments when presence matters more than perfection.

Choosing Your Potatoes

Yukon Gold potatoes are the gold standard here because their buttery flavor and waxy structure dissolve into the soup without becoming mealy or starchy. They're also beautiful—pale and yielding—which means your finished soup has an almost pale jade color that feels refined. That said, I've made this with russets when that's what was in the pantry, and it worked; the soup was just slightly less creamy and a touch more earthy, which some people actually prefer.

Making It Your Own

This recipe is forgiving enough to adapt without losing its soul. If you want earthiness, add fresh thyme to the pot while simmering. If you like a hint of smoke, finish with a whisper of smoked paprika. Some people add a splash of white wine before the broth, which adds brightness, or swap the chives for crispy sage if you're in a different mood entirely. The base—leeks, potatoes, butter, cream—that's the promise the soup makes, and everything else is just conversation around it.

Storage, Reheating, and Serving Ideas

This soup keeps for up to three days in the fridge and actually tastes better the next day once flavors have merged overnight. Reheat gently on the stove over low heat, stirring occasionally, and add a splash of broth or milk if it's thickened too much. It also freezes beautifully for up to two months—just leave out the cream, freeze the base, and stir it in after reheating. Serve it as a first course before roasted fish or chicken, alongside crusty bread and good butter, or as a light dinner with a simple green salad dressed in bright vinaigrette.

• For a richer version, drizzle each bowl with truffle oil or finish with crispy bacon bits and sharp cheddar.
• If you're making this vegan, use olive oil instead of butter and oat or cashew cream instead of dairy—it's equally luxurious.
• Leftover soup is perfect poured over baked potatoes or stirred into grain bowls for unexpected depth.

Pin It

This soup has become the recipe I return to when I want to cook something that feels both simple and nourishing, like I'm taking care of myself or someone I love. It's proof that elegance doesn't require complexity—just good ingredients and enough attention to let them become something greater together.
