Why You'll Love This Recipe
- Uses everyday ingredients you probably already have.
- Naturally creamy without adding any cream.
- Family-friendly and easy to adjust for taste.
- Ready in under 40 minutes.
- Perfect for make-ahead meals or freezing.
Ingredients
- 2 tablespoons extra-virgin olive oil
- 3 large leeks, white and light green parts only, sliced
- 2 garlic cloves, minced
- 4 cups vegetable broth, plus more for a thinner texture
- 2 pounds Yukon Gold potatoes, peeled and diced into ½-inch pieces
- 1 teaspoon kosher salt
- 1 bay leaf
- 2 fresh thyme sprigs
- Freshly chopped chives and black pepper for serving
Ingredient Notes & Substitutions
- Yukon Gold potatoes give a naturally creamy texture, but russet potatoes work if that's what you have.
- Vegetable broth keeps the flavor delicate, though chicken broth adds a richer base.
- If your leeks seem sandy, soak them briefly in a bowl of cool water. The grit will sink.
- Fresh thyme brings soft herbal notes, but dried thyme can be used in a pinch. Start with ½ teaspoon.
Instructions
- Prep the leeks. Slice off the tough stems and green leaves so you're left with the pale parts. Cut them in half lengthwise, then slice across.
- Clean them well. Leeks love to hide dirt. Wash the chopped pieces in a colander under cool running water until completely clean.
- Cook the leeks. Warm the olive oil in a large pot over medium heat. Add the leeks and cook for 8 to 10 minutes until soft and fragrant. They should look glossy, not browned. Stir in the garlic for one minute.
- Add potatoes and broth. Pour in the vegetable broth and add the potatoes, salt, bay leaf, and thyme. Bring the pot to a gentle boil, then lower the heat, cover, and simmer 15 to 20 minutes until the potatoes are tender.
- Blend the soup. Remove the bay leaf and thyme. Use an immersion blender to puree until smooth or leave a little texture if you like a rustic feel. A blender works too; just blend in batches.
- Serve. Ladle the warm soup into bowls and top with chives and black pepper. A swirl of olive oil adds a lovely finish.
Pro Tips for Success
Top Tip
- Wash leeks thoroughly. Even a little grit can distract from the silky texture.
- If the soup thickens as it cools, thin it with a splash of broth when reheating.
- For a richer flavor, let the leeks cook low and slow until soft and sweet.
- If blending in a regular blender, vent the lid and cover with a towel for safety.
Storage and Reheating
- Refrigerate for up to 3 days in an airtight container.
- Reheat gently on the stovetop over low heat.
- Freeze up to 3 months. Thaw overnight before reheating.
Make Ahead & Freezing
This soup is perfect for making ahead. Prepare it fully, cool completely, and freeze in smaller portions. The texture stays beautifully smooth once reheated.
Tips and Variations
- Add a splash of white wine to the leeks as they sauté for brightness.
- Stir in a spoonful of sour cream for extra richness.
- Add spinach or kale during blending for a green twist.
- Top with crispy bacon or roasted chickpeas for crunch.
- Serve with warm crusty bread for a heartier meal.

Description
There is nothing quite like a bowl of warm, silky Potato Leek Soup on a chilly day. The leeks melt into sweetness, the potatoes turn velvety and tender, and the whole pot fills your kitchen with a soft, savory aroma that feels like comfort itself. This is my favorite version-gentle, earthy, and deeply soothing.
Ingredients
- 2 tablespoons extra-virgin olive oil
- 3 large leeks, white and light green parts only, sliced
- 2 garlic cloves, minced
- 4 cups vegetable broth, plus more for a thinner texture
- 2 pounds Yukon Gold potatoes, peeled and diced into ½-inch pieces
- 1 teaspoon kosher salt
- 1 bay leaf
- 2 fresh thyme sprigs
- Freshly chopped chives and black pepper for serving
Instructions
- Prep the leeks by slicing off the tough stems and green leaves, leaving the pale parts. Cut in half lengthwise, then slice across.
- Wash the chopped leeks thoroughly in a colander under cool running water to remove any dirt.
- Warm olive oil in a large pot over medium heat. Add the leeks and cook for 8 to 10 minutes until soft and glossy. Stir in the garlic and cook for 1 more minute.
- Pour in the vegetable broth, then add the potatoes, salt, bay leaf, and thyme. Bring to a gentle boil, reduce heat, cover, and simmer for 15 to 20 minutes until the potatoes are tender.
- Remove bay leaf and thyme. Blend the soup using an immersion blender until smooth, or leave some texture for a rustic feel. A regular blender works too-blend in batches.
- Ladle into bowls and top with chives and black pepper. A swirl of olive oil makes a nice finishing touch.
Notes
Wash leeks thoroughly-grit can ruin the silky texture. If the soup thickens, add broth when reheating. For richer flavor, cook the leeks low and slow. Vent the blender lid and use a towel for safety when blending hot soup. Refrigerate up to 3 days or freeze up to 3 months. Add white wine while sautéing, stir in sour cream, or blend in greens like spinach. Try topping with crispy bacon or roasted chickpeas, and serve with crusty bread for a full meal.
