Creamy Potato Leek Soup with Chives

There is something incredibly grounding about the smell of leeks softening in butter on a rainy afternoon. It turns the kitchen into a cozy sanctuary before the soup even begins to bubble. This creamy potato leek soup has become my go to comfort meal when the weather turns gray. It is simple, elegant, and feels like a warm hug in a bowl.

I made a huge batch of this last winter when a friend was recovering from a bad cold. She took one sip and looked at me with genuine relief, saying it was exactly what her body needed. We sat by the window watching the snow fall while nursing our bowls. It reminded me that sometimes the simplest food is the most healing.

Ingredients

• 2 large leeks: The white and light green parts provide the sweetest flavor and must be cleaned well.
• 1 medium onion: This builds a solid aromatic foundation for the soup base.
• 3 medium potatoes: Russet or Yukon Gold potatoes break down beautifully for a thick texture.
• 2 cloves garlic: Minced fresh garlic adds a punch of aromatic depth.
• 4 cups vegetable stock: A high quality stock ensures the final flavor is robust.
• 1 cup milk: Whole milk adds body without making the soup too heavy.
• 1/2 cup heavy cream: This creates that velvety restaurant style finish.
• 2 tbsp unsalted butter: Butter is essential for sweating the vegetables properly.
• 1 bay leaf: It infuses a subtle herbal note while the soup simmers.
• 1/2 tsp black pepper: Freshly ground pepper makes all the difference in seasoning.
• 1 tsp salt: Adjust this to your personal preference at the end.
• 2 tbsp fresh chives: These add a pop of color and mild onion flavor.

Instructions

Sauté the aromatics:

Melt the butter in a large pot over medium heat before adding the leeks and onion. Cook them gently for about eight minutes until they are soft and translucent.

Add the garlic:

Toss in the minced garlic and stir constantly for one minute so it does not burn. This step releases the aromatic oils into the fat.

Simmer the base:

Add the diced potatoes, salt, pepper, bay leaf, and vegetable stock to the pot. Bring everything to a boil then lower the heat to let it simmer for twenty minutes.

Blend the soup:

Fish out the bay leaf and use an immersion blender to puree the soup until it is completely smooth. Take care with hot liquids if you use a standard blender.

Add the cream:

Pour in the milk and heavy cream and stir to combine everything well. Warm the soup gently over low heat until it is heated through.

Serve the dish:

Ladle the hot soup into bowls and finish with a generous sprinkle of fresh chives. A swirl of extra cream on top makes for a beautiful presentation.

Pin it

This soup became a staple during a particularly busy month when I barely had time to breathe. I realized I could throw it together in minutes and let it simmer while I caught up on chores. It taught me that good food does not require hours of active labor to be satisfying. Now it is my rainy day ritual without fail.

Dairy Free Options

You can easily swap the butter and dairy for plant based alternatives without losing the creamy texture. Coconut milk works surprisingly well here if you want a richer flavor profile.

Texture Secrets

The secret to the velvety consistency is using starchy potatoes like Russets. They naturally thicken the broth as they break down during the simmering process.

Serving Suggestions

This soup pairs wonderfully with a crusty baguette to soak up every last drop. A light side salad adds some crunch to balance the smooth texture.

• Toast some crusty sourdough for dipping.
• Add a dollop of sour cream on top.
• Sprinkle with crispy bacon bits if you eat meat.

I hope this soup brings as much comfort to your table as it has to mine. Enjoy every spoonful of this simple pleasure.

Recipe FAQ

→ Can I make this soup ahead of time?

Yes, this soup actually improves in flavor when made ahead. Prepare it completely, then refrigerate for up to 3 days. Reheat gently over low heat, stirring occasionally. You may need to add a splash of milk or stock when reheating if it thickens too much.

→ What potatoes work best for creamy texture?

Russet or Yukon Gold potatoes are ideal. Russets break down easily for a smoother purée, while Yukon Golds offer a naturally buttery flavor. Avoid waxy potatoes like red or new potatoes, as they won't break down as well during blending.

→ How do I clean leeks properly?

Leeks often hide dirt between their layers. Slice them first, then place in a bowl of cold water. Swish around vigorously—dirt will sink to the bottom. Lift the leeks out carefully, leaving the sediment behind. Repeat until the water remains clear.

→ Can I freeze this soup?

Yes, though the texture may change slightly. Cool completely before transferring to airtight containers, leaving space for expansion. Freeze for up to 3 months. Thaw overnight in the refrigerator and reheat gently, whisking to recombine. For best results, add cream after thawing and reheating.

→ What can I serve with this soup?

Crusty bread, baguette slices, or garlic crostini are classic accompaniments. A simple green salad with vinaigrette balances the richness. For heartier meals, pair with a quiche or grilled cheese sandwich. The soup also works well as a first course for a multi-course dinner.

→ How do I adjust the thickness?

If too thick, add more stock or milk, 1⁄4 cup at a time, until desired consistency. If too thin, simmer longer to reduce, or mash additional cooked potatoes into the soup. Remember it will thicken slightly as it cools.
