What is Easy Potato Leek Soup?
Easy Potato Leek Soup is a classic, velvety-smooth potage that relies on the mild, sweet flavor of leeks combined with the heartiness of russet potatoes. Unlike heavy cream-based soups, this version uses yogurt to achieve that signature silkiness without weighing you down. Its roots trace back to traditional farmhouse cooking, where root vegetables were always readily available and perfect for filling, warming soups.
The magic happens when the leeks are sautéed slowly in butter until they are tender and sweet. By blending the potatoes once they are soft, the starch creates a naturally thick and creamy consistency that feels indulgent. It is a humble, refined dish that proves you can create something memorable with just a few pantry staples.

Ingredients Needed to Make Easy Potato Leek Soup
- 2 tablespoons unsalted butter
- 3 large leeks, white and pale green parts only, thoroughly washed and chopped
- 1/2 cup white onion, diced into small pieces
- 5 cups low-sodium chicken broth
- 3 medium russet potatoes, peeled and cut into uniform 1-inch cubes
- 1 1/4 teaspoons kosher salt
- 1/2 teaspoon garlic powder
- 2 whole bay leaves
- 1/2 teaspoon dried thyme
- 1/2 teaspoon black pepper
- 1/2 cup plain Greek yogurt mixed with 1/4 cup warm water
- Fresh chives and extra thyme for garnish
Instructions to Make Easy Potato Leek Soup – Step by Step
Step 1: Start by placing your favorite large soup pot over medium heat. Add the butter and let it melt until it begins to froth slightly. Toss in your prepared leeks and diced onions, using a wooden spoon to stir them as they soften. You want to cook these for about 10 minutes until they are translucent and fragrant, but be sure not to let them brown as we want that gentle, sweet flavor to shine through.
Step 2: Carefully pour in your chicken broth and add the peeled, cubed potatoes to the pot. Stir in the salt, garlic powder, bay leaves, dried thyme, and black pepper. Bring the mixture to a gentle boil, then lower the heat slightly and let it simmer uncovered for around 15 minutes. You will know it is ready when the potatoes are fork-tender and begin to break apart slightly when pressed.
Step 3: Remove the pot from the heat and discard the two bay leaves, as they have done their job of infusing the broth. Using an immersion blender directly in the pot or a standard countertop blender, process the soup until it is completely smooth and creamy. If you use a standard blender, keep a kitchen towel over the lid to prevent any hot splashes, especially if your children are hovering around the kitchen.
Step 4: In a small bowl, whisk together the plain Greek yogurt and the warm water until smooth. This tempering step prevents the yogurt from curdling when it hits the hot liquid. Gradually stir this mixture into your blended soup, whisking constantly to create a perfectly velvet consistency. Taste the soup and add a pinch more salt or pepper if your personal palate calls for it.
Step 5: Ladle the warm soup into bowls and garnish generously with fresh chopped chives and a few leaves of thyme. Serve this alongside some rustic bread or crunchy croutons to round out the meal. The warmth of the soup and the brightness of the fresh herbs make every bowl feel like home.
Chef’s Tips for a Perfect Result
- Always clean your leeks thoroughly as dirt hides between the layers: slice them in half lengthwise and rinse under cold water.
- Use an immersion blender to save on cleanup time and keep the soup in one pot throughout the process.
- Temper your Greek yogurt with a bit of warm water or broth before adding it to the pot to ensure a smooth, curd-free finish.
- If you want a thicker soup, mash a few of the potatoes with a fork before blending to release extra natural starch.
Variations and Substitutions
- Vegan Option: Swap the butter for a high-quality olive oil and replace the chicken broth with a rich vegetable stock. Use a plant-based unsweetened yogurt alternative to keep the creamy texture.
- Gluten-Free Alternative: This recipe is naturally gluten-free as long as you confirm your chicken broth does not contain hidden wheat-based thickeners.
- Low-Carb Version: Replace the russet potatoes with cauliflower florets. You will get a similar creamy texture with a significant reduction in total carbohydrates.
- Budget Swap: If you do not have leeks, you can increase the amount of yellow onion and add a leek-flavored bouillon base to capture that distinct flavor profile.
How to Serve and Pair
This soup shines when served in wide, shallow bowls that show off a garnish of fresh chives and thyme. It pairs beautifully with a side of crusty sourdough bread, which is perfect for dunking into the creamy broth. For an elegant dinner touch, add a handful of homemade parmesan croutons for a nice textural contrast against the velvet soup.
Storage and Reheating
Refrigerator: Allow the soup to cool completely to room temperature before placing it in an airtight container. It will keep for 3 to 4 days and often tastes even better the next day as the flavors develop.
Freezer: Transfer cooled soup into freezer-safe bags or containers, leaving a little room for expansion. It can be frozen for up to 3 months.
Reheating: Reheat on the stovetop over medium-low heat, stirring frequently. If the soup has thickened too much in the fridge, whisk in an extra splash of broth or water to return it to your desired consistency. When using a microwave, reheat in 2-minute bursts, stirring in between to ensure even heating.

Frequently Asked Questions (FAQ)
Can I use milk instead of Greek yogurt?
You can use heavy cream or whole milk instead of Greek yogurt for a richer flavor, though you will lose the extra protein boost. If choosing milk, let the soup simmer for a few minutes after adding it to ensure it incorporates fully without separating.
How do I know when the potato leek soup is done?
The soup is ready to blend once the russet potatoes are fork-tender and begin to mash easily against the side of the pot. Ensure the potatoes are soft enough that they disintegrate with minimal pressure to achieve that signature silky mouthfeel.
Why is my soup too thin?
If your soup is thinner than you like, continue to simmer it uncovered for a few extra minutes to allow some moisture to evaporate. Alternatively, you can stir in a small amount of extra yogurt or blend in one additional cooked potato to naturally thicken the base.
Can I prep the ingredients in advance?
You can absolutely prep the leeks and potatoes up to 24 hours in advance to save time on your busy weeknight. Store the chopped leeks in a sealed bag and keep the cubed potatoes submerged in a bowl of cold water in the fridge to prevent them from turning brown.
What are the best toppings for this soup?
While fresh chives and thyme are classic, you can customize your bowl with toasted pumpkin seeds, a swirl of olive oil, or crispy shallots. These toppings add a necessary crunch that balances the creamy nature of the soup perfectly.
