Save to Pinterest I stumbled upon this combination on a particularly gloomy Tuesday when the grocery store felt too far away. My pantry offered only a few wrinkly potatoes and a bundle of leeks that had seen better days. As the butter started to foam in the pot the kitchen transformed into a cozy sanctuary. It reminded me that you do not need a long list of ingredients to make something that feels special. This soup has since become my go to remedy for long days and chilly evenings.
The first time I served this to my family I forgot to strain the leeks properly and we found a bit of garden soil at the bottom. We all just laughed and used the crusty bread to scoop up every last creamy drop anyway. It was one of those rare moments where the conversation mattered more than the perfection of the meal. Now I always think of that laughter whenever I start slicing into a fresh leek. It is a dish that seems to encourage people to slow down and stay a while.

Ingredients
- Unsalted Butter: This creates a silky fat base that helps the vegetables release their natural sugars without sticking.
- Olive Oil: Adding a splash of oil prevents the butter from browning too quickly while you are softening the aromatics.
- Leeks: These provide a sophisticated and gentle sweetness that is much lighter than a standard onion.
- Yellow Onion: I use this to add a foundational savory note that rounds out the flavor profile.
- Garlic Cloves: Mincing these fresh ensures a punchy aroma that mellows beautifully during the long simmer.
- Yukon Gold Potatoes: Their natural starchiness acts as a built in thickener which gives the soup a luxurious body.
- Celery Stalks: This adds an earthy depth that keeps the soup from tasting one dimensional.
- Vegetable Broth: Using a light broth allows the delicate flavor of the leeks to really shine through.
- Whole Milk: A splash of milk at the end provides a creamy finish without masking the vegetable flavors.
- Bay Leaf: This single leaf infuses the liquid with a subtle herbal note that makes the soup taste professional.
- Fresh Thyme: The bright and woody scent of thyme is the perfect companion for earthy potatoes.
- Black Pepper: A generous crack of pepper provides a tiny bit of heat to balance the rich creaminess.
- Kosher Salt: Salt is essential here because potatoes require a good amount of seasoning to wake them up.

Instructions
- Soften the base:
- Begin by melting the butter and oil together before adding your sliced leeks and onions to the pot. Let them cook gently until they are translucent and soft but be careful not to let them take on any brown color.
- Add aromatics:
- Toss in the garlic and celery and stir them for a few minutes until the fragrance fills your kitchen. This quick step helps to toast the garlic slightly and softens the crunch of the celery.
- Simmer the vegetables:
- Stir in the diced potatoes and herbs before pouring in the broth to cover everything completely. Bring the pot to a boil then lower the heat and cover it until the potatoes are tender enough to mash with a spoon.
- Puree the soup:
- Remove the bay leaf and use an immersion blender to process the mixture until it is completely smooth and silky. You can leave a few small chunks of potato if you prefer a more rustic and homemade texture.
- Incorporate the dairy:
- Stir in the milk and let the soup return to a gentle simmer so all the flavors can meld together. Taste a spoonful and add more salt or pepper if you think it needs a bit more pop.
- Garnish and serve:
- Ladle the hot soup into bowls and top with your choice of crispy bacon or fresh chives for a beautiful presentation. If you are adding seafood just fold it in at the very end until it is warmed through.

I remember one rainy autumn evening when the power went out right as I finished blending the soup. We lit every candle in the house and ate by the flickering light while the rain drummed on the roof. The soup stayed warm in the heavy pot and it felt like the most luxurious meal we had ever eaten. It proved to me that some recipes are meant for the quietest moments of life.
The Best Potato Choice
While you can use Russets I highly recommend sticking with Yukon Golds for their creamy texture and buttery flavor. They blend much more smoothly and do not get as grainy as other varieties when they are pureed.
Enhancing the Flavor
If you want a deeper flavor you can try roasting the garlic before adding it to the pot. This adds a caramelized sweetness that pairs perfectly with the mildness of the leeks and cream.
Storage and Reheating
This soup stores incredibly well in the fridge for up to three days and the flavor actually improves over time.
- Add a splash of water or broth when reheating because the potatoes will continue to absorb liquid as they sit.
- Avoid freezing this soup if possible as the dairy and potatoes can sometimes change texture once thawed.
- Reheat it slowly on the stove rather than the microwave to maintain that perfectly smooth and velvet consistency.

Recipe FAQs
- → Can I make this ahead of time?
Absolutely. This soup actually develops deeper flavors when made a day ahead. Store in the refrigerator and reheat gently, adding a splash more liquid if needed.
- → What's the best way to clean leeks?
Slice the leeks lengthwise, then chop. Place in a bowl of cold water and swish around to let grit settle to the bottom. Lift out the clean leeks and discard the sandy water.
- → Can I freeze this?
Yes, freeze for up to 3 months. Thaw overnight in the refrigerator. Note that the texture may change slightly upon reheating—whisk in a little extra milk or cream to restore smoothness.
- → What potatoes work best?
Yukon Gold or other waxy potatoes are ideal as they hold their shape during cooking and blend into a naturally creamy texture without becoming gluey.
- → How do I make it dairy-free?
Replace the butter with additional olive oil and use coconut milk, almond milk, or cashew cream instead of dairy milk. The result remains velvety and delicious.
- → What protein additions work well?
Cooked shrimp, scallops, or white fish transform this into a seafood chowder. Crispy bacon, pancetta, or even shredded chicken also pair beautifully with the creamy base.
