The Secret Ingredient That Makes All the Difference
I’ve tested countless variations, and this one addition is a game-changer. It’s the key to that luxurious mouthfeel.
The secret is raw cashews. You’ll blend them right into the soup. They give a natural creaminess and body that coconut milk can’t match. It’s a neutral base that lets the potato and leek flavors shine through.
Why This Method is Better (My Pro-Tips)
My method focuses on building a deep flavor foundation. This is what separates a good soup from a great one.
We start by sautéing the leeks low and slow. This sweats them, drawing out their natural sweetness without any browning. That sweet, mellow base is everything. Then, we add a splash of white wine for a bright, acidic kick that balances the richness.

The “Upgraded” Ingredient List
Using high-quality, simple ingredients is crucial. Here’s everything you’ll need for this creamy soup.
- 2 large leeks, white and light green parts only, thoroughly washed and sliced
- 3 cloves garlic, minced
- 2 tbsp olive oil
- 1.5 lbs Yukon Gold potatoes, peeled and diced
- 1/2 cup dry white wine (like Sauvignon Blanc)
- 4 cups vegetable broth
- 1/2 cup raw cashews, soaked in hot water for 15 minutes
- 1 tsp fresh thyme leaves
- 1/2 tsp smoked paprika
- Salt and black pepper to taste
- Fresh chives, for garnish
PREPARATION
Follow these steps closely. The order of operations is designed to build flavor at every stage.
- Heat the olive oil in a large pot over medium-low heat. Add the sliced leeks and a pinch of salt. Cook for 10-12 minutes, stirring often, until they are very soft and sweet. Do not let them brown.
- Add the minced garlic and cook for one more minute until fragrant.
- Pour in the white wine to deglaze the pot, scraping up any bits from the bottom. Let it simmer for 2 minutes until the sharp alcohol smell cooks off.
- Add the diced potatoes, vegetable broth, and fresh thyme. Bring to a boil, then reduce heat and simmer for 15-20 minutes, until the potatoes are fork-tender.
- While the soup simmers, drain the soaked cashews. Add them to a blender with about 1 cup of the hot broth from the pot. Blend on high until completely smooth and creamy.
- Carefully ladle the rest of the soup into the blender with the cashew cream. You may need to do this in two batches. Blend until velvety smooth.
- Return the blended soup to the pot. Stir in the smoked paprika, and season with salt and pepper to taste. Warm through over low heat.
- Serve immediately, garnished with fresh chives and an extra crack of black pepper.
Common Mistakes & How to Fix Them
Even experienced cooks can run into these issues. Here’s how to avoid them and make sure your soup is perfect.
Gritty Leeks: The most common mistake is not washing leeks well. They trap sand between their layers. After slicing, submerge them in a bowl of water and swish them around. The grit will sink to the bottom.
Watery Soup: If your soup is too thin after blending, don’t just add more potatoes. Simmer it for a bit longer to reduce and concentrate the flavors. The starch from the potatoes will naturally thicken it as it cooks down.
Variations for the Adventurous Cook
Once you’ve mastered the base recipe, try these pro-level swaps to keep things interesting.
For a smoky twist, add two teaspoons of miso paste when you add the broth. It adds a deep, savory note. You can also roast the potatoes first for a richer, nuttier flavor profile. Just toss them in oil and roast at 400°F until golden before adding to the pot.

Your Pro-Level Questions Answered
I get a lot of great questions about this recipe. Here are the answers to the most common ones.
Can I make this soup ahead of time?
Absolutely. This soup tastes even better the next day. Let it cool completely before storing it in an airtight container in the fridge for up to 4 days. Reheat gently on the stovetop.
My blender isn’t very powerful. Will that be a problem?
Not at all. Just make sure you soak your cashews for the full 15 minutes in very hot water. This softens them up and makes them much easier to blend into a smooth cream, even with a standard blender.
What can I use instead of white wine?
You can simply omit it. For a similar acidic brightness, add a tablespoon of fresh lemon juice at the very end, right before serving. It will give you that same pop of flavor.
A Few Final Secrets
You now have all the tools to make an incredible pot of soup. Remember, cooking is about confidence and a little bit of know-how.
The real secret is patience. Taking your time with the leeks and building the flavors step-by-step is what creates a truly memorable dish. This method will power up all your other creamy soup recipes, too.
