Creamy Leek Potato Soup

I was rummaging through the vegetable drawer on a rainy afternoon when I found three forgotten leeks tucked in the back, their green tops still crisp. A few potatoes sat nearby, and suddenly the idea of something warm and silky felt urgent. I chopped everything without much ceremony, let the butter melt, and within the hour my kitchen smelled like a quiet bistro I'd wandered into once in Lyon.

The first time I made this for friends, I added too much nutmeg and worried the whole pot was ruined. But when I ladled it into mismatched bowls and set them on the table with torn bread, everyone went quiet in that way people do when food surprises them. One friend asked for the recipe twice before she left.

Ingredients

• Leeks: Use only the white and pale green parts, they turn sweet and tender when simmered, slice them thin and rinse well because sand hides between the layers.
• Yukon Gold Potatoes: These break down into creaminess without turning gluey, peel them or leave the skins on if you want a more rustic texture.
• Onion: It builds a quiet sweetness in the background, dice it small so it disappears into the broth.
• Garlic: Just two cloves are enough to add warmth without shouting, mince them finely and don't let them brown.
• Vegetable Broth: This is the backbone of the soup, use a good quality one or homemade if you have it, the flavor really shows.
• Milk or Cream: A single cup makes everything silky, whole milk works beautifully but heavy cream feels like a special occasion, plant-based milk keeps it light.
• Butter: It coats the leeks as they soften and adds richness you can taste, swap it for olive oil if you want to keep things vegan.
• Seasonings: Salt, pepper, and a pinch of nutmeg bring everything together, the nutmeg is subtle but it makes people wonder what the secret is.
• Chives or Parsley: A small handful on top adds color and a fresh bite that cuts through the creaminess.

Instructions

Soften the Aromatics:

Melt the butter over medium heat and add the leeks and onion, stirring often for 6 to 8 minutes until they turn glossy and soft but not browned. The smell alone will make you want to skip ahead.

Add the Garlic:

Toss in the minced garlic and cook for just a minute, stirring constantly so it doesn't stick or burn.

Stir in the Potatoes and Spices:

Add the diced potatoes, salt, pepper, and nutmeg, then cook for 2 minutes to let the flavors mingle. You'll notice the nutmeg smells warm and almost sweet.

Simmer in Broth:

Pour in the vegetable broth and bring everything to a boil, then lower the heat and let it simmer uncovered for 20 minutes. The potatoes should be so tender they fall apart when you press them with a spoon.

Blend Until Smooth:

Remove the pot from the heat and use an immersion blender to puree everything until it's completely smooth, or carefully transfer it in batches to a countertop blender. Be patient, the creamier the better.

Finish with Dairy:

Stir in the milk or cream and reheat gently without letting it boil, then taste and adjust the seasoning. Sometimes I add a tiny pinch more salt or a crack of pepper.

Serve and Garnish:

Ladle the soup into bowls and scatter fresh chives or parsley on top. A drizzle of good olive oil doesn't hurt either.

I started making this soup on Sunday nights when the week ahead felt heavy. There's something about stirring a pot of something simple and watching it transform that makes everything else feel manageable. It became a ritual I didn't plan but couldn't imagine giving up.

How to Store and Reheat

This soup keeps beautifully in the fridge for up to four days in an airtight container. When you reheat it, do it gently over low heat and stir often, adding a splash of broth or milk if it's thickened too much. I've also frozen it in portions, though the texture can separate slightly when thawed, a quick whisk or blend brings it back together.

Ways to Make It Your Own

I've stirred in a handful of spinach at the end for color, swapped half the potatoes for cauliflower when I wanted something lighter, and once added a spoonful of miso paste instead of salt which gave it a deep, almost meaty richness. A squeeze of lemon juice right before serving brightens the whole bowl, and crispy bacon or roasted chickpeas on top turn it into something heartier.

Serving Suggestions

This soup feels complete on its own, but I almost always serve it with crusty bread for dipping, the kind with a hard crust and soft middle. A simple green salad with vinaigrette balances the richness, and if I'm feeling fancy, I'll toast some sourdough with garlic butter and float a piece on top of each bowl.

• Pair it with a crisp white wine like Sauvignon Blanc or a light lager if you want something cold alongside.
• Top with crispy shallots or toasted pine nuts for texture and a bit of crunch.
• Serve it in wide, shallow bowls so the garnish looks beautiful and you get a little in every spoonful.

This soup has become the thing I make when I want to feel grounded, when I need something that smells like comfort and tastes like care. I hope it does the same for you.
