This One Pot Leek and Potato Soup is warm and creamy, making it perfect for chilly days. With just leeks, potatoes, and a few seasonings, it’s a simple hug in a bowl!
I love how easy it is to make! Just chop everything, sauté, and let it simmer. Plus, I can enjoy it with some crusty bread. What’s better than that? 😊
Key Ingredients & Substitutions
Leeks: Use the white and light green parts for a milder flavor. If you can’t find leeks, green onions or scallions can work in a pinch, but keep in mind they’ll have a stronger taste.
Potatoes: The recipe calls for medium potatoes, which provide a nice texture. If you’re short on potatoes, try using frozen hash browns for a quicker option!
Broth: You can use vegetable or chicken broth here. Homemade broth is great, but store-bought works just as well! For a low-sodium option, choose reduced-salt broth.
Heavy Cream: This adds richness to the soup, but you can use milk for a lighter version. If you’re dairy-free, coconut milk or almond milk are good substitutes, adding a unique flavor twist.
How Do I Get the Best Flavor from My Soup Base?
Getting the best flavor out of your soup starts with the right sauté. Using medium heat, cook the onions and garlic first to enhance their sweetness and aroma. Don’t rush this step—3-4 minutes is perfect for softening without browning. After that, add the leeks, cooking them until soft, about 5-7 minutes, stirring occasionally.
- Heat the pot before adding butter or oil to prevent sticking.
- Stir gently to avoid browning the vegetables; we want them tender, not caramelized.

How Much Time Will You Need?
This delicious soup takes about 10 minutes to prep and around 30 minutes to cook, making a total of about 40 minutes from start to finish. A perfect cozy dish for any day of the week!
Step-by-Step Instructions:
1. Sauté the Base:
In a large pot, heat the butter or olive oil over medium heat. Once it’s warm, add the chopped onions and minced garlic. Sauté them for about 3-4 minutes until they’re softened and fragrant, creating a nice base for your soup.
2. Cook the Leeks:
Add the sliced leeks to the pot. Stir them in and cook for another 5-7 minutes, stirring occasionally. The goal is to soften the leeks without browning them, which helps keep the soup’s flavor smooth.
3. Add Potatoes and Broth:
Next, add the diced potatoes and pour in the broth. Bring the mixture to a boil, then reduce the heat to a simmer. Let it cook for about 20 minutes or until the potatoes are tender. This is when all those lovely flavors blend together!
4. Blend Until Smooth:
Once the potatoes are tender, you have two options: use an immersion blender right in the pot to puree the soup until it’s smooth, or carefully transfer the soup in batches to a blender. If you choose the latter, blend until smooth and then return it to the pot.
5. Add Cream and Season:
Stir in the heavy cream or milk. Let the soup heat gently on low for about 5 minutes without bringing it to a boil. Season with salt and freshly ground black pepper to taste, bringing out all the wonderful flavors.
6. Serve and Enjoy:
Serve the soup hot! Garnish with chopped fresh chives or green onions, a sprinkle of croutons, a dusting of black pepper, and a drizzle of olive oil if you like. Enjoy your cozy, creamy One Pot Leek and Potato Soup!
Can I Use Different Types of Potatoes for This Soup?
Absolutely! While the recipe calls for medium potatoes, you can use Yukon Gold or even red potatoes. Just keep in mind that waxy potatoes may give the soup a slightly different texture compared to starchy ones.
What Should I Do If My Soup is Too Thick?
If your soup turns out thicker than you’d like, simply add a little more broth or water until you reach your desired consistency. Heat it through after adding so everything mixes well!
Can I Freeze Leftover Soup?
Yes, you can freeze leftover soup! Let it cool completely, then transfer it to airtight containers or freezer bags. It can be stored in the freezer for up to 3 months. When you’re ready to eat it, thaw it overnight in the fridge and reheat on the stove.
How Can I Make This Soup Vegan?
To make this soup vegan, substitute the heavy cream with coconut cream or a plant-based cream alternative, and use vegetable broth. You can also replace the butter with olive oil for sautéing.
