Ingredients You’ll Need
Gathering the right ingredients is like laying the foundation for a fantastic meal. This recipe keeps it simple yet essential — each ingredient plays a crucial role in delivering creamy texture, comforting warmth, and a beautiful balance of flavors and color.
- Leeks (white and light green parts): Provide the sweet, delicate onion base that makes this soup uniquely flavorful and aromatic.

- Leek Top Broth or vegetable broth: The heart of the soup — the leek top broth infuses an intense, sweet onion flavor unmatched by vegetable broth alone.
- Fresh thyme sprigs: Add an earthy herbal brightness that complements the potatoes and leeks perfectly.
- Milk or heavy cream: For richness and a silky finish that makes the soup truly creamy without being heavy.

How to Make Creamy Potato Leek Soup with Leek Top Broth Recipe
Step 1: Make the Leek Top Broth (Optional but Recommended)
If you really want to elevate this soup, making the leek top broth is worth the extra step. Use the dark green tops of your leeks—they’re usually discarded, but here they give you a rich, sweet broth. Simply simmer these tops with water, thyme, garlic, salt, and peppercorns for about 30 minutes, then strain. This broth is the secret ingredient that intensifies the soup’s natural leek flavor and adds a whole new dimension.
Step 2: Prepare the Soup Base
Start by cleaning and chopping the white and light green parts of your leeks. Cook them gently in butter over medium heat, seasoning with sea salt and black pepper as they soften without browning. This slow cooking unlocks their natural sweetness and creates a mellow, aromatic foundation for the soup.
Step 3: Build Rich Flavors With Potatoes and Broth
Add the chopped Yukon gold potatoes, grated garlic, your leek top broth or vegetable broth, and a bundle of fresh thyme sprigs to the pot. Let everything simmer until the potatoes are tender and ready to be blended. This step melds the flavors together and softens the potatoes to create that creamy texture we all love.
Step 4: Blend to Creamy Perfection
Remove the thyme bundle and blend the soup until smooth using an immersion blender or by carefully transferring it to a regular blender. This is where the magic happens—turning those simple ingredients into a luxuriously velvety soup. Stir in milk or cream for richness, then season to taste. A splash of fresh lemon juice here is optional but highly recommended to brighten the final flavor.
How to Serve Creamy Potato Leek Soup with Leek Top Broth Recipe
Garnishes
Fresh chopped chives are the classic choice for garnishing this soup, providing a subtle fresh onion flavor and a pop of lovely green color. You might also try a swirl of cream, a sprinkle of crispy bacon bits, or even a dash of smoked paprika to add a smoky twist. These small touches elevate the presentation and flavor to make every bowl feel special.
Side Dishes
This soup pairs beautifully with rustic crusty bread or a warm baguette to soak up every creamy drop. A simple mixed green salad with a light vinaigrette can balance the richness, or for extra indulgence, serve alongside garlic-roasted vegetables or a cheesy grilled sandwich. Whichever way you go, these sides create a well-rounded meal perfect for any day of the week.
Creative Ways to Present
For a cozy dinner party, serve your soup in small, elegant cups for easy sipping as an appetizer. For a heartier lunch or dinner, ladle generous portions into deep bowls and add your favorite garnishes right before serving. Using colorful soup bowls or wooden bowls can make your presentation warm and inviting. You could even top the soup with a delicate herb oil drizzle or a crisp herb leaf for extra flair.
Make Ahead and Storage
Storing Leftovers
This soup keeps beautifully in the refrigerator for up to 3 days in an airtight container. Because it’s so creamy, you might notice it thickens when chilled—just stir in a splash of milk or broth when reheating to bring it back to the perfect consistency.
Freezing
This Creamy Potato Leek Soup with Leek Top Broth Recipe also freezes well. Be sure to cool the soup completely before transferring it to freezer-safe containers. Freeze in portions for convenience; frozen soup is best consumed within 2 months for optimal flavor and texture.
Reheating
Reheat gently on the stove over low to medium heat, stirring often to prevent sticking. If the soup is too thick after refrigeration or freezing, add a little broth or milk bit by bit until it reaches your desired creamy consistency. Reheating slowly preserves the soup’s delicate flavors and silky texture.
FAQs
Can I use a different type of potato?
Yes! While Yukon gold potatoes are ideal for their creaminess and buttery flavor, you can substitute russet potatoes if needed. Just keep in mind that russets tend to be more starchy and may produce a slightly different soup texture.
What if I don’t have fresh thyme?
If fresh thyme isn’t on hand, dried thyme works in a pinch—use about one-third the amount of fresh thyme called for. Alternatively, rosemary or a bay leaf can add pleasant earthy notes.
Can I make this soup vegan?
Absolutely! Simply swap the butter for olive oil or vegan margarine, use vegetable broth instead of leek top broth, and substitute the milk or cream with your favorite plant-based milk. The soup will still be creamy and comforting.
Is making leek top broth necessary?
While you can use store-bought vegetable broth, making your own leek top broth significantly enhances the soup’s oniony sweetness and depth. It’s a simple step that transforms this recipe into something truly special.
Can I add other vegetables to this soup?
Yes! Diced celery or carrots can be sautéed with the leeks for extra flavor complexity. Just adjust cooking times slightly to ensure everything becomes tender before blending.

It’s easy to make and can be served garnished with fresh chives for an elegant touch.
Ingredients
For the Soup
- 4 large leeks (white and light green parts only), about 2½ pounds, chopped and washed
- 3 tablespoons unsalted butter
- 1 teaspoon sea salt
- Freshly ground black pepper, to taste
- 2 pounds Yukon gold potatoes or yellow potatoes, chopped
- 3 garlic cloves, grated
- 6 cups Leek Top Broth (see below) or vegetable broth
- 3 fresh thyme sprigs, bundled
- 1 cup milk or heavy cream
- 1 tablespoon fresh lemon juice (optional)
- Chopped fresh chives, for garnish
Optional Leek Top Broth
- 4 large leeks (dark green tops only), about 2½ pounds, washed
- 12 cups water
- 8 fresh thyme sprigs
- 5 garlic cloves, smashed
- 1 tablespoon sea salt
- 1 tablespoon black peppercorns
Instructions
- Make the leek top broth (optional): Cut off the dark green tops from the leeks, wash thoroughly, and add to a large pot with water, thyme sprigs, smashed garlic, salt, and peppercorns. Bring to a boil over high heat, then reduce to a simmer and cook for 30 minutes. Strain the broth, measure out 6 cups for the soup, and store any remaining broth in the refrigerator or freezer for later use.
- Prepare the soup leeks: Chop the white and light green parts of the leeks and wash well to remove any grit.
- Sauté the leeks: Heat the butter in a large pot or Dutch oven over medium heat. Add the chopped leeks, sea salt, and freshly ground black pepper. Cook for 8 to 10 minutes, stirring occasionally, until the leeks are soft and translucent. Reduce the heat if the leeks begin to brown before softening.
- Add potatoes, garlic, broth, and thyme: Stir in the chopped potatoes, grated garlic, 6 cups of leek top broth or vegetable broth, and bundled thyme sprigs. Bring to a simmer and cook for about 20 minutes or until the potatoes are very soft and tender.
- Blend the soup: Remove the thyme sprigs. Use an immersion blender directly in the pot or carefully transfer the soup in batches to a blender to puree until smooth and creamy. Return the blended soup to the pot.
- Finish the soup: Stir in the milk or heavy cream, and season to taste with additional salt, pepper, and optional fresh lemon juice for brightness.
- Serve: Ladle the soup into bowls and garnish with chopped fresh chives. Serve warm.
Notes
- If you don’t have leek tops to make the broth, any good-quality vegetable broth will work well.
- Using Yukon gold potatoes gives a creamy texture without needing to add flour or thickeners.
- The optional lemon juice adds a nice brightness but can be omitted if preferred.
- For a richer soup, use heavy cream; for a lighter version, substitute with milk or a plant-based milk alternative.
- Store leftovers in an airtight container in the refrigerator for up to 3 days or freeze for up to 2 months.
- Before blending, be careful when transferring hot soup to a blender to avoid burns—blend in batches if needed.
