2. Ingredients Breakdown
Leeks
The star of the soup. Their mild, sweet onion flavor becomes the foundation. Clean thoroughly to remove sand.
Potatoes
Yukon Gold or Russet potatoes provide creaminess and body. Yukon Gold yields a naturally buttery texture.
Butter
Used to sauté leeks and add richness. Can substitute with olive oil for a lighter version.
Vegetable or Chicken Stock
Forms the liquid base; vegetable stock keeps it vegetarian.
Heavy Cream or Milk (Optional)
Adds richness and smooth texture; adjust according to preference.
Salt and Pepper
Enhances natural flavors.
Fresh Herbs (Optional)
Chives, thyme, or parsley can brighten the soup.
Substitutions
- For dairy-free: use olive oil and coconut milk.
- Use leeks only if potatoes are too starchy, but the combination balances flavors beautifully.
- Add garlic for additional flavor if desired.
- For a thicker soup, partially mash potatoes or blend fully.
3. Step-by-Step Instructions
1. Clean and Slice Leeks
Trim root ends and dark green tops, leaving only white and light green parts. Slice thinly and rinse thoroughly in a bowl of cold water to remove any grit.
2. Sauté Leeks
In a large pot, melt butter over medium heat. Add leeks and sauté until soft and fragrant, about 5–7 minutes. Do not brown; the goal is gentle caramelization.
3. Add Potatoes and Stock
Peel and dice potatoes, then add them to the pot. Pour in stock until vegetables are just covered. Bring to a simmer and cook for 20 minutes, or until potatoes are tender.
4. Blend the Soup
Use an immersion blender to puree until smooth. For a chunkier texture, blend partially or leave some potatoes whole.
5. Add Cream and Season
Stir in heavy cream or milk. Season with salt and pepper to taste. Heat gently without boiling.
6. Finish with Herbs
Add fresh chopped chives, parsley, or thyme for brightness and aroma.
7. Serve
Ladle into bowls and garnish with a swirl of cream, a sprinkle of herbs, or crispy croutons. Serve with crusty bread.
