Ingredients Needed to Make Easy Potato Leek Soup
- 2 tablespoons butter (unsalted is best for controlling flavor)
- 3 large leeks (use only the clean white and pale green parts, sliced)
- 1/2 cup diced white onion (provides a foundational savory base)
- 5 cups low-sodium chicken broth (or vegetable broth for a strictly vegetarian version)
- 3 medium russet potatoes (peeled and diced for thickening)
- 1 1/4 teaspoons salt (adjust to personal preference)
- 1/2 teaspoon garlic powder
- 2 bay leaves (removed before blending)
- 1/2 teaspoon dried thyme
- 1/2 teaspoon black pepper
- 1/2 cup plain Greek yogurt (plus 1/4 cup warm water to temper it)
- Fresh chives and extra thyme (for a vibrant, herbal garnish)
Instructions to Make Easy Potato Leek Soup – Step by Step
Step 1: Start by melting your butter in a large pot over medium heat until it begins to froth slightly. Add your prepped leeks and diced onions, stirring them frequently so they soften without browning. This gentle sweat releases their natural sweetness.
Step 2: Carefully pour in the chicken broth and stir in your cubed potatoes, salt, garlic powder, bay leaves, thyme, and pepper. Bring the mixture to a gentle simmer, letting the potatoes soften until they are fork-tender, which usually takes about 15 minutes.
Step 3: Once the potatoes are soft, remove the pot from the heat and discard the bay leaves. Use an immersion blender directly in the pot, or transfer the mixture to a standard blender, to process the soup until it reaches a perfectly silky, uniform consistency.
Step 4: Take your Greek yogurt and whisk it with the warm water in a small bowl until smooth. Slowly incorporate this mixture into your blended soup, which helps temper the yogurt and prevents curdling, while adding a beautiful, light tang and a protein boost.
Step 5: Give the soup a final stir, taste it to see if it needs an extra pinch of salt or pepper, and serve it warm. Ladle into your favorite bowls and top with plenty of fresh chives and a sprig of thyme for a bright, aromatic finish.
Chef’s Tips for a Perfect Result
- Clean your leeks thoroughly by slicing them lengthwise and running them under water to remove trapped grit.
- Use russet potatoes rather than waxy varieties, as their high starch content is essential for a naturally creamy texture.
- Temper your yogurt with warm water before adding it to the hot soup to ensure a smooth, professional consistency.
- Blend until completely smooth, but try not to over-process as it can sometimes make the potato starch turn gummy.
Variations and Substitutions
- Vegan Option: Swap the butter for extra virgin olive oil and replace the Greek yogurt with coconut cream or a plant-based unsweetened yogurt alternative.
- Gluten-Free Alternative: This recipe is naturally gluten-free, provided you ensure your broth choice is certified gluten-free.
- Budget Swap: If fresh herbs aren’t available, rely on dried chives; the base flavor of the leeks and potatoes carries the dish beautifully on its own.
How to Serve and Pair
Serve this soup in deep, warmed bowls to maintain its comforting temperature throughout the meal. It pairs beautifully with a slice of crusty sourdough bread or a side of simple garlic-rubbed toast for dipping.
For a complete lunch, add a light green salad tossed in a lemon vinaigrette to balance the richness of the soup. This menu works wonderfully for casual Sunday lunches or quick weeknight dinners where you want to focus on wellness and clarity.
Storage and Reheating
Refrigerator: Once cool, store the soup in an airtight glass container to preserve the freshness for up to 3 to 4 days.
Freezer: Place the cooled soup in a freezer-safe bag or container; it can be stored for up to 3 months, though it is best enjoyed sooner.
Reheating: Reheat slowly on the stovetop over medium-low heat, stirring occasionally to prevent the bottom from scorching. If it has thickened too much in the fridge, feel free to add a splash of broth or water to bring it back to your desired consistency.

Frequently Asked Questions (FAQ)
Can I use milk instead of yogurt?
You can use whole milk or heavy cream if you prefer a richer flavor profile, though yogurt adds a unique tang and extra protein. Simply stir in the dairy at the very end to prevent it from curdling.
How do I know the potatoes are cooked enough?
The potatoes are done when they break apart easily with the gentle pressure of a fork. They should be soft enough to blend into a smooth puree without leaving any chunks behind.
Why is my soup bland?
Your soup likely needs a final adjustment of salt to bring out the earthy notes of the leeks. Always taste your soup one last time before serving, as the potato starch absorbs salt during the cooking process.
Can I make this soup the night before?
This soup is actually a wonderful make-ahead recipe, as the flavors continue to develop and meld while sitting in the refrigerator overnight. Just store it in an airtight container and reheat gently the next day.
What is the best way to garnish this bowl?
Fresh chives provide the best contrast in color and a subtle onion bite that accentuates the leek profile. You can also add toasted pumpkin seeds or a drizzle of olive oil for added texture and visual appeal.
