This warming Irish soup features tender leeks and diced potatoes gently simmered in vegetable stock until soft. A touch of cream is stirred in to create a rich, velvety texture. Aromatics like onion, garlic, and bay leaf enhance the depth of flavor, while fresh herbs add a final bright note. Easy to prepare, it’s perfect for chilly days or light meals, delivering a smooth, satisfying experience with every spoonful.

The first time I made this soup was during a particularly relentless March rain that would not quit. I had bought leeks on impulse without any plan, and something about their mild onion sweetness felt right for a gray afternoon. My kitchen filled with that gentle buttery aroma that makes you want to put on soft socks and stay inside. This is the soup that taught me simple ingredients, treated with patience, create the most honest kind of comfort.

I served this to my sister when she was recovering from surgery, too tired to chew anything demanding. She kept asking what secret ingredient I had used, certain there was something complicated hiding in the bowl. The look on her face when I listed only leeks, potatoes, cream, and butter was pure delight. Sometimes the most nourishing food is just honest ingredients treated with respect and time.

Ingredients

  • 2 large leeks: Use only the white and light green parts, dark greens can be tough and bitter in smooth soups
  • 500 g potatoes: Yukon Gold or russet work beautifully, avoid waxy varieties that resist breaking down
  • 1 medium onion: Provides a subtle foundation that complements without competing with the leeks
  • 2 cloves garlic: Minced fresh, add it with the leeks so it mellows into sweetness
  • 1 L vegetable stock: Good quality stock makes a difference, homemade or low sodium store bought
  • 200 ml heavy cream: Stirred in at the end, do not boil after adding or it may separate
  • 2 tbsp unsalted butter: The base for sautéing your vegetables, builds rich flavor from the start
  • 1 bay leaf: Adds subtle depth while simmering, remove before blending
  • Salt and black pepper: Season gradually and taste often, cream mutes seasoning so adjust accordingly

Instructions

Build Your Flavor Base:
Melt the butter in a large saucepan over medium heat, add the sliced leeks, chopped onion, and minced garlic. Cook gently for 6 to 8 minutes until softened and fragrant, stirring occasionally to prevent browning.
Add the Potatoes:
Stir in the diced potatoes and bay leaf, coating everything well with the buttery vegetable mixture. Let them cook for just a couple of minutes to start absorbing those flavors.
Simmer to Tenderness:
Pour in the vegetable stock and bring to a gentle boil, then reduce heat and simmer uncovered for about 20 minutes. The potatoes should be very tender when pierced with a fork.
Create Your Texture:
Remove and discard the bay leaf, then use a stick blender to purée the soup until completely smooth. You can also leave it slightly chunky if you prefer some texture.
Finish with Cream:
Stir in the heavy cream and season generously with salt and freshly ground black pepper. Reheat gently if needed, but never let it boil after the cream joins the party.
Serve and Garnish:
Ladle the warm soup into bowls and sprinkle with chopped fresh chives or parsley if you like. A piece of crusty bread on the side never hurts either.

This recipe became my go to comfort soup during a lonely winter when work kept me away from family. Something about stirring the pot, watching steam rise, and smelling that gentle leek sweetness made even the hardest days feel manageable. Food has this quiet way of holding us together when we need it most.

Making It Your Own

I have made countless variations of this soup over the years, sometimes swapping half the cream for whole milk when I want something lighter. A pinch of nutmeg stirred in at the end adds a whisper of warmth that people notice but cannot quite identify. Fresh thyme sprigs simmered with the potatoes and removed before blending bring an herbal brightness.

Texture Choices

Some days I crave this soup completely smooth and silken, other times I purposefully leave small potato chunks for heartiness. A stick blender gives you control to stop exactly where you want, while a regular blender requires working in batches and being careful with hot liquid. Both methods work, but the stick blender lets you taste and adjust as you go.

Serving Suggestions

This soup shines as a starter but also stands alone as a light dinner with good bread and a simple green salad. I have served it in everything from rustic earthenware bowls to delicate porcelain cups at parties. The versatility is part of why I return to it again and again.

  • Crusty sourdough toasted with garlic butter makes each spoonful feel like an event
  • A dollop of crème fraîche and extra chives turns it into something dinner party worthy
  • Leftovers taste even better the next day as flavors have more time to marry
