What Ingredients are in Creamy Potato Leek Soup?
Here’s everything you’ll need to make this cozy, comforting bowl of creamy potato leek soup that’ll warm you from the inside out.
- 4 leeks (white and light green parts only), sliced and thoroughly rinsed
- 2 tablespoons unsalted butter
- 2 pounds Yukon Gold potatoes, peeled and chopped
- 4 cups vegetable or chicken broth
- 1 bay leaf
- Salt and pepper to taste
- 1/2 cup heavy cream (optional)
Feel free to customize with additional garnishes like fresh chives, crispy bacon bits, or a swirl of good olive oil—and don’t worry if you’re watching your dairy intake, as the heavy cream is completely optional and the soup is still wonderfully silky without it.
How to Make this Creamy Potato Leek Soup
Step 1: Prepare the Leeks
Thoroughly slice 4 leeks, using only the white and light green parts, then rinse them well under cold water.
Leeks can hide dirt between their layers, so don’t skip this essential cleaning step—nobody wants gritty soup!
Step 2: Sauté the Leeks
Melt 2 tablespoons of unsalted butter in a large pot over medium heat, then add your cleaned leeks.
Cook them gently until they’re soft and translucent, about 7 minutes, stirring occasionally to prevent any browning.
Step 3: Add Potatoes and Liquid
Add 2 pounds of peeled and chopped Yukon Gold potatoes to the pot with the softened leeks.
Pour in 4 cups of vegetable or chicken broth, depending on your preference, then drop in 1 bay leaf for that subtle herbal note.
Step 4: Season the Soup
Sprinkle in salt and freshly ground black pepper to taste.
The amount really depends on the saltiness of your broth and your personal preference, but starting with about 1/2 teaspoon of each is a good rule of thumb.
Step 5: Simmer Until Tender
Bring the mixture to a gentle boil, then reduce the heat and let everything simmer until the potatoes are completely tender, approximately 15-20 minutes.
You’ll know they’re done when a fork slides easily through them.
Step 6: Remove Bay Leaf and Purée
Fish out the bay leaf—it’s done its job and nobody wants to bite into it!
Then, using an immersion blender, purée the soup until smooth and velvety. If you don’t have an immersion blender, you can transfer batches to a regular blender (just be careful with the hot liquid).
For perfect silky results every time, consider investing in an essential food processor and blender set that can handle both chunky preparations and smooth puréeing tasks.
Step 7: Add the Finishing Touch
For extra richness, stir in 1/2 cup of heavy cream if using.
This step is completely optional—the soup is already quite silky from the potatoes, but the cream adds a luxurious touch that’s hard to resist on a cold day.
Step 8: Serve and Garnish
Ladle the hot soup into bowls and garnish with freshly snipped chives, a drizzle of good olive oil, or even some crispy bacon bits if you’re feeling indulgent.
Sometimes I even add a tiny swirl of truffle oil when company’s coming—talk about fancy with minimal effort!
What to Serve with Creamy Potato Leek Soup
This velvety soup makes a perfect lunch or light dinner, especially when paired with something to round out the meal. A crusty baguette or grilled cheese sandwich is practically mandatory—there’s nothing better for sopping up those last precious spoonfuls.
For something fresher, try a crisp green salad with a tangy vinaigrette that cuts through the soup’s richness. On chillier evenings, a glass of buttery Chardonnay or crisp apple cider complements the soup’s earthy flavors beautifully.
Want to make it more substantial? Top each bowl with crumbled bacon or homemade croutons tossed with herbs. Trust me, these simple pairings transform this humble soup into a complete meal worth lingering over.

Leftovers and Storage for this Creamy Potato Leek Soup
This soup actually tastes even better the next day when the flavors have had time to meld together—one of those magical recipes that improves with a little patience!
- Refrigerator storage: Transfer cooled soup to airtight containers and refrigerate for up to 4 days.
- Freezer option: For longer storage, freeze portions in freezer-safe containers for up to 3 months. Just leave a bit of headspace for expansion.
- Reheating tips: Warm gently on the stovetop over medium-low heat, stirring occasionally. The soup may thicken when chilled—simply add a splash of broth or water to reach your desired consistency.
