Ingredients You’ll Need

The magic behind this creamy potato leek soup starts with fresh leeks and Yukon gold potatoes, which give the perfect balance of flavor and texture. Plus, making the leek top broth elevates the taste substantially, so if you have time, go for it!

• Leeks (white and light green parts only): These have a sweet, mild onion flavor; make sure to clean them thoroughly since dirt can hide within the layers.
• Unsalted butter: Adds richness and a lovely silky mouthfeel to your soup—feel free to swap with olive oil if you prefer.
• Sea salt: Essential for bringing out all those wonderful flavors; always taste as you go for balance.
• Freshly ground black pepper: Adds a gentle heat and depth to the soup without overpowering it.
• Yukon gold potatoes: Their waxy texture helps create that creamy consistency without needing tons of cream.
• Garlic cloves (grated): Gives a subtle warmth and pleasant aroma, just enough to complement but not dominate.
• Leek top broth or vegetable broth: Using homemade leek broth intensifies the leek flavor unparalleled by store-bought versions.
• Fresh thyme sprigs: Adds a herbal freshness—don’t skip this little detail, it makes a big difference.
• Milk or heavy cream: I usually opt for milk to keep this lighter, but cream makes it ultra indulgent.
• Fresh lemon juice (optional): A splash brightens the final soup and balances the creaminess.
• Chopped fresh chives (for garnish): These tiny green rings add a subtle onion crunch and beautiful color on top.
• Leek tops for broth: Don’t throw these away; use them to make the broth for a fuller, deeper leek flavor.
• Water: Base for your broth; keep it clean and fresh.
• Black peppercorns: Simmered in the broth for nuanced spice without harsh intensity.

Variations

One of the best things about this Creamy Potato Leek Soup Recipe is how flexible it is. I often tweak it depending on the season or who’s coming for dinner—it comes out delicious every time.

• Swap the cream for coconut milk: I tried this once for a dairy-free version, and it added a subtle sweetness that was lovely without losing the creamy texture.
• Add crispy bacon or smoked salmon: It gives a smoky contrast that my family adores especially on chilly nights.
• Use sweet potatoes or cauliflower: For a different twist and nutrient boost, these veggies blend beautifully and still yield that velvety finish.
• Make it vegan: Just replace the butter with olive oil and use a plant-based milk; it’s still hearty and flavorful.

How to Make Creamy Potato Leek Soup Recipe

Step 1: Make the Leek Top Broth (Optional but Worth It!)

If you want to take your soup to the next level, start by making the leek top broth. Grab the dark green parts of your leeks, wash them well (they can be gritty), then toss them into a large pot with water, thyme sprigs, smashed garlic cloves, sea salt, and black peppercorns. Bring it all to a boil, then simmer gently for about 30 minutes. Strain it, measure 6 cups, and save. I usually freeze whatever is leftover to use later in risottos or stews. Trust me, this step turns ordinary vegetable broth into something special that boosts the flavor beautifully.

Step 2: Cook the Leeks Until Soft and Sweet

Next, finely chop the white and light green parts of your leeks. Clean them well so no hidden dirt remains. Heat the butter in a large pot or Dutch oven over medium heat. Add the leeks, sprinkle the sea salt, and grind in some black pepper. Cook gently for about 8 to 10 minutes. You’re aiming for softness, not browning, so if they start to color too quickly, turn down the heat. The smell at this point is so inviting—I always sneak a little taste.

Step 3: Simmer Potatoes, Garlic, and Broth

Once your leeks are soft and fragrant, toss in the chopped Yukon gold potatoes and grated garlic. Pour in your leek broth or vegetable broth, then add the fresh thyme sprigs. Bring everything to a gentle simmer and let it cook for about 20 minutes until the potatoes are super tender. This is key—the softer the potatoes, the creamier your soup will become. Don’t rush this step!

Step 4: Blend and Add Cream

Remove the thyme sprigs, then use an immersion blender right in the pot to puree the soup until silky smooth. If you don’t have an immersion blender, careful transfers to a blender work just as well—just watch out for hot splashes! Once smooth, stir in the milk or cream and season to taste. I like to add a splash of fresh lemon juice at this point; it really perks up the flavors and cuts some of the richness beautifully. Give it a final taste and add salt or pepper if needed.

Step 5: Garnish and Serve

The final flourish is chopped fresh chives scattered over each bowl. Not only do they lend a pretty touch of green, but they add a gentle onion crunch that contrasts perfectly with the creamy texture. Serve this soup hot, and enjoy the comfort and flavor in every spoonful.

Garnishes

I love topping this soup with freshly chopped chives to bring a pop of color and a mild, oniony crunch. Sometimes I add a drizzle of good olive oil, or if I’m feeling indulgent, a dollop of crème fraîche or sour cream adds an extra dreamy texture.

Side Dishes

My favorite pairing includes crusty bread or buttery toasted baguette slices to soak up every last drop. A simple green salad with a bright vinaigrette balances the creamy soup nicely, making for a comforting yet well-rounded meal.

Creative Ways to Present

For special dinner guests, I like serving the soup in little ramekins as an appetizer, garnished with microgreens or tiny herb sprigs. Another fun idea is to swirl in a bit of pesto or chili oil on top for a swirl of color and a flavor twist.

Make Ahead and Storage

Storing Leftovers

This soup stores beautifully in an airtight container in the refrigerator for up to 4 days. When I make a big batch, I label it so I don’t forget, and it’s always great to have for quick lunches or cozy evenings.

Freezing

I’ve frozen this soup several times with excellent results. Just let it cool completely, transfer to freezer-safe containers, and use within 3 months. When thawed, it may thicken slightly, so just add a splash of broth or water while reheating to bring it back to perfect pourability.

Reheating

The best way to reheat is gently on the stovetop over low heat, stirring occasionally to prevent scorching. If the soup has thickened too much, add a little milk or broth to loosen it up. Microwave works in a pinch too, but go slow and stir often for even heating.
