Recommended Products for This Recipe
I’ve tested countless kitchen tools over the years, and these are the ones that genuinely make a difference when preparing this soup.
1. Le Creuset Enameled Cast Iron Dutch Oven
This pot distributes heat so evenly that your soup cooks perfectly without any hot spots or scorching.
The heavy lid traps moisture and flavor, and the enamel coating makes cleanup incredibly easy. I’ve had mine for over a decade, and it still looks and performs like new.
2. KitchenAid Immersion Blender
This immersion blender saves you from transferring hot soup to a regular blender, which can be messy and dangerous.
You can blend the soup right in the pot to your desired consistency, and it’s powerful enough to create a silky smooth texture in seconds.
3. Organic Fresh Thyme
Fresh herbs make such a difference in this soup compared to dried ones. The aromatic quality of fresh thyme adds depth and brightness that dried herbs simply can’t match.
It’s worth keeping a small pot on your windowsill year-round.
4. High-Quality Chicken Broth
The broth is the foundation of your soup’s flavor, so using a quality one matters. Look for low-sodium options so you can control the seasoning yourself, and choose organic when possible for the cleanest, most authentic taste.
Step-by-Step Instructions: How to Make Potato Leek Soup
Follow these detailed steps for perfect potato leek soup every time. I’ve broken down each step so even beginners can achieve restaurant-quality results.
1. Clean and Prepare the Leeks
- Trim off the dark green tops and root ends of the leeks
- Cut each leek in half lengthwise
- Rinse thoroughly under cold running water, separating the layers to remove any dirt or sand trapped between them
- Slice the cleaned leeks into thin half-moons, about 1/4 inch thick
- Pat them dry with a clean kitchen towel
2. Sauté the Aromatics
- Heat the butter in your Dutch oven over medium heat until it melts and starts to foam
- Add the sliced leeks and a pinch of salt
- Cook for 8 to 10 minutes, stirring occasionally, until the leeks soften and become translucent
- Add the minced garlic and cook for another minute until fragrant
- Don’t let the garlic brown, as it can turn bitter
3. Add the Potatoes and Broth
- Add the diced potatoes to the pot and stir to coat them with the butter and leeks
- Pour in the chicken or vegetable broth
- Drop in the bay leaf and sprinkle in the fresh thyme leaves
- Increase the heat to high and bring the mixture to a boil
- Once boiling, reduce the heat to medium-low and let it simmer
4. Simmer Until Tender
- Cover the pot partially with a lid
- Simmer for 20 to 25 minutes, or until the potatoes are completely tender when pierced with a fork
- The potatoes should break apart easily when pressed against the side of the pot
- Remove and discard the bay leaf
5. Blend the Soup
- Use an immersion blender to puree the soup directly in the pot until smooth
- If using a regular blender, work in batches and fill the blender only halfway to prevent hot liquid from splashing
- For a chunkier texture, blend only half the soup and leave the rest as is
- Return blended soup to the pot if using a regular blender
6. Add the Cream and Season
- Stir in the heavy cream until fully incorporated
- Taste the soup and season with salt and pepper as needed
- Heat gently for another 2 to 3 minutes without boiling
- Adjust the consistency by adding more broth if too thick or simmering longer if too thin
7. Serve and Garnish
- Ladle the hot soup into bowls
- Sprinkle each serving with chopped fresh chives
- Add a drizzle of extra cream or a pat of butter if desired
- Serve immediately with crusty bread on the side

FAQs About Potato Leek Soup
1. Can I make this soup dairy-free?
Yes, you can easily make this soup dairy-free by using plant-based alternatives. Replace the butter with olive oil or vegan butter, and swap the heavy cream for coconut cream or cashew cream.
The soup will still be rich and creamy, though the flavor will be slightly different.
2. Why did my soup turn out watery?
Watery soup usually happens when too much liquid is added or the soup isn’t simmered long enough.
Try simmering uncovered for a few extra minutes to reduce the liquid and concentrate the flavors. You can also add an extra potato or two to help thicken it naturally.
3. Can I use other types of potatoes?
While Yukon Gold potatoes work best because of their creamy texture, you can use russet potatoes for a fluffier consistency or red potatoes for a firmer texture.
Avoid waxy potatoes like fingerlings, as they don’t break down as well when blended.
4. How do I fix soup that’s too thick?
Simply thin it out by adding more broth or cream, a quarter cup at a time, until you reach your desired consistency.
Heat gently while stirring to incorporate the liquid evenly throughout the soup.
5. Can I use the green parts of the leeks?
The dark green tops are quite tough and fibrous, so they’re not ideal for this creamy soup.
However, you can save them to make homemade vegetable broth instead of throwing them away.

Notes
- Clean leeks thoroughly: Leeks trap dirt between their layers — always split them lengthwise and rinse well under running water before slicing.
- Use Yukon Gold potatoes: Their naturally buttery flavor and creamy texture make them ideal for this soup. Russets work but yield a fluffier result.
- Don’t rush the leeks: Slow-cooking them for 8–10 minutes brings out their natural sweetness, which is key to the soup’s flavor.
- Add cream at the end: Stirring in cream off-heat or over low heat prevents curdling and keeps the soup silky smooth.
- Don’t boil after adding cream: High heat can cause the cream to separate and ruin the texture.
- Make it dairy-free: Substitute olive oil for butter and coconut cream or cashew cream for the heavy cream.
- Serve chilled as Vichyssoise: Chill the blended soup completely and serve cold with extra chives for an elegant French classic.
- Storage: Refrigerate in an airtight container for up to 4 days, or freeze (without cream) for up to 3 months. Reheat gently on the stovetop with a splash of broth.
- Reheating tip: If the soup has thickened in the fridge, stir in a splash of broth or cream while reheating over medium-low heat.
- Use leek tops for broth: Save the dark green tops — they’re perfect for homemade vegetable stock.
