Creamy Potato Leek Soup

There's something about a steaming bowl of potato leek soup that stops time. I was standing in my kitchen on a gray November afternoon, and my neighbor had just dropped off a bunch of leeks from her garden—long, elegant stalks I'd never quite known what to do with. That day, I decided to build something around them, layering in potatoes and cream until the whole pot turned into liquid velvet. The turkey bacon on top? That was my version of a happy accident, a salty crunch that made everyone at the table pause mid-spoon and ask what made it taste so good.

My sister came home from college that first time I made this, and I remember her walking into the kitchen, stopping dead, and saying, "Wait, did you make soup?" She sat at the counter with a bowl before I even finished plating, and that single moment—her pure contentment—made me understand why I love cooking this particular dish. It's become our thing now, something she requests before every visit.

Ingredients

• Large leeks: The heart of this soup—clean them thoroughly between the layers where dirt hides, and use only the white and light green parts for a sweeter, more delicate flavor.
• Yukon Gold potatoes: They break down into creamy silk, thickening the soup naturally without cream alone doing the work.
• Turkey bacon: A lighter alternative that still delivers that essential savory depth and textural contrast.
• Chicken or vegetable broth: Good broth is half the battle; taste it before you buy, because it's the backbone of everything else.
• Whole milk or half-and-half: Add it at the end so it doesn't break or curdle from prolonged heat.
• Olive oil: Just enough to build flavor without making the soup feel heavy.
• Kosher salt, black pepper, thyme, nutmeg: These seasonings whisper rather than shout—start conservative and taste your way forward.
• Fresh chives or parsley: The final garnish that brings brightness and reminds you that this soup is alive, not heavy.

Instructions

Render the turkey bacon first:

Heat a tablespoon of olive oil in your pot and let the bacon cook slowly until every edge is crispy. You'll know it's done when it smells irresistible and looks deep golden, about 5 to 7 minutes.

Build your flavor base with leeks and onion:

In that same pot (all those bacon drippings are your secret), add the remaining oil and let the leeks and onion soften into something almost translucent. This takes patience—about 5 to 6 minutes over medium heat—and it's when the real flavor foundation happens.

Add potatoes and spices, then pour in the broth:

Stir everything together, let it cook for just 2 minutes so the spices wake up, then add your broth. Bring it to a boil, then dial it down to a gentle simmer, cover, and let time do the work for about 18 to 20 minutes until the potatoes surrender completely.

Blend until silky:

An immersion blender right in the pot is the easiest path—work it through until the soup turns smooth and velvety. If you prefer more texture, leave some chunks; if you like it restaurant-style, blend longer.

Finish with cream and gentle heat:

Stir in your milk or half-and-half and warm it through over low heat, never letting it boil or the cream might separate. Taste and adjust the salt, pepper, and spices to your preference.

Serve with all the toppings:

Ladle into bowls, crown each with crumbled turkey bacon, and finish with a scatter of fresh chives or parsley for color and brightness.

Pin It

What surprised me most about this soup is how it became a bridge between seasons—something I make in the crisp first weeks of fall, but also something that feels right on a bitter January night. It's humble food that tastes anything but, and that's the sweetest thing a home cook can offer.

The Leek Story

Leeks often get overlooked in favor of their louder cousins—onions and garlic—but they're the quiet sophisticate of the allium family. When cooked slowly, they soften into something almost buttery, sweet without being cloying, and they're the reason this soup tastes like comfort instead of just vegetables and broth. They're also incredibly forgiving; unlike onions, they won't burn or turn harsh, they'll just get sweeter the longer you let them cook.

Why the Potatoes Matter

Yukon Gold potatoes are waxy and naturally buttery, which means they release starch slowly as they break down, giving the soup that silky, almost creamy texture without needing to add cream until the very end. If you use russets, which are starchier, you'll get something thicker and more paste-like; if you use red potatoes, they'll hold their shape longer and the soup will be brothier. Understanding which potato does what gives you control over texture—and that control is where cooking becomes fun instead of guesswork.

Making It Your Own

The beauty of this soup is that it's a foundation, not a rulebook. Some nights I add a bay leaf, other times a splash of white wine or even a pinch of cayenne for heat. I've experimented with roasting the leeks and onions first to deepen the flavor, and I've made it entirely dairy-free for friends who needed that. The turkey bacon can become pancetta if you're feeling fancy, or skip it entirely if you want it vegetarian. What matters is that you make it until it tastes like home to you.

• Consider adding a splash of white wine before the broth for subtle depth.
• Roasting the vegetables first will intensify flavors if you have extra time.
• Freeze leftovers without the cream, then thaw and finish when you're ready to eat.

There's a reason this soup shows up on tables across seasons and reasons—it's honest food that doesn't ask for much but gives so much back. Make it once, and it becomes part of your rotation forever.

Recipe Questions

→ What potatoes work best for this soup?

Yukon Gold potatoes provide a creamy texture when cooked and blended, but russet potatoes can be used for a slightly lighter consistency.

→ Can I use a different type of bacon?

Turkey bacon offers a leaner option, but you can substitute with pork bacon or omit entirely for a lighter finish.

→ How can I make this soup dairy-free?

Replace the milk or half-and-half with unsweetened oat milk or coconut milk to maintain creaminess without dairy.

→ What herbs enhance this soup’s flavor?

Fresh chives or parsley add a fresh note, while dried thyme and a pinch of nutmeg bring subtle warmth and depth.

→ Is blending necessary for texture?

Blending creates a smooth, creamy base, but leaving it slightly chunky offers a rustic feel depending on preference.

→ How to avoid over-salting the soup?

Start with a teaspoon of kosher salt and adjust after blending to suit your taste, keeping in mind the bacon adds some saltiness.
