Potato–Leek Soup Recipe
My mother-in-law was French… as in she was a French citizen before she moved to the United States and became a US Citizen. The French are wonderful cooks, and my MIL was no exception to that rule. Hubby definitely inherited that gene from her!
Potato-leek soup is a traditional French soup made with fresh leeks. It is an inexpensive soup, full of rich flavors, creamy texture, and it is oh so good; French comfort food at its finest. If you have never tried potato-leek soup, or if the potato-leek soup is one of your favorites, try this version; you will be glad you did.
This is a good soup recipe to make if it is you are a first-time soup maker. Do not let the number of ingredients put you off; this is a simple homemade soup that is easy to make.
How to Make Potato-Leek Soup
1. Cook Leeks – In an 8-quart pot or larger, melt the butter and add in the leeks to cook until they are soft.
2. Add More Ingredients – Once the leeks are soft, add in the milk, potatoes, seasonings, herbs, and chicken stock. Stir and cover for about an hour until potatoes are soft.
3. Add Cornstarch – In a small bowl, mix together the cornstarch and water. Add to soup and stir. Cook for ten more minutes.
4. Blend and Enjoy – Using an immersion blender, blend the soup before adding the cream to the mixture. Garnish with chives if desired, and enjoy!
Tips and variations for Making Potato–Leek Soup Recipe
● Instead of buying chicken stock, make your own sodium-free chicken stock. You can also buy sodium-free chicken bouillon and make your chicken stock according to those directions. It isn’t quite the same, but it will do in a pinch and helps if you prefer vegetarian. I do suggest you make your own though – it is pretty easy. Or, if you prefer, make your own no sodium vegetable stock and use that instead.
● You can substitute vegetable broth for chicken broth; just realize it will change the taste of the soup.
● Yukon gold potatoes lend a very pretty yellow color to this soup. Use them if you can find them.
● You may want to read about Hubby’s Waring Immersion Blender. This is one of his favorite kitchen tools and very handy to have when making soups.
● For a chunkier soup, you can skip the blending step, although the resulting soup may be a little thinner than you would expect for this type of recipe.
● Make it spicy – If you want to make it spicy, you can add some crushed red pepper flakes or even slice a fresh jalapeno and add it to the soup with the rest of the vegetables.
● Add a little hot sauce when serving if you would like a little heat.
● Thicken the soup – If the texture of the soup doesn’t seem thick enough, you can simmer it a little longer in order to cook off some of the extra liquid. You can also add a bit more cornstarch dissolved in water if need be, or some instant potato flakes. Make sure and allow the soup to cool more before attempting to thicken it as it does thicken as it cools. The next day may be a better choice on deciding to thin or thicken this soup recipe.
● Thin the soup – if you like soup with a thinner consistency you can add some more chicken stock to thin it out.
● This potato-leek soup recipe freezes beautifully. Just make certain you use freezer grade containers. Hubby buys them in giant packs, and we keep the extras down the basement. Our freezer sometimes looks like a frozen soup factory exploded in it. We freeze soup, stews, leftovers, garden vegetables, etc for later use all year long!
● Storage – This potato leek soup freezes really well. Simply store it in an airtight container for up to 3 months. It can also be stored in the fridge in an airtight container for up to 5 days.
Common Questions about Potato-Leek Soup
What Kind of Potatoes Do You Use for Soup?
Starchier potatoes such as russet potatoes are usually the best for this type of soup because they soften and break apart well. This makes it easier to blend the ingredients and makes the soup thicker as well as make it easier to consume. Waxier potatoes like Yukon gold don’t “fall apart” as easily, although they still make for a delicious soup. If possible, go with the starchier-style potatoes, but if you don’t have a choice, the soup will still be delicious regardless.
Can You Freeze Mason Jars with Soup?
Yes, you definitely can freeze soup in mason jars. I usually like to use the wide-mouth mason jars. It’s best to let the soup cool before spooning it into the jars as this could cause the lid to loosen once it cooled, causing it to freezer burn or go bad. Mason jars are also great for storing one to two servings, at a time, of the soup in order to make reheating quite a bit easier. That way, you don’t have to pull out all of the soup that’s leftover in order to just get one serving. Keeps it fresher longer. On another note, be careful not to tightly pack the jars as this could cause breaking in the freezing process. This means, don’t stack them too close to each other and don’t overfill them.

Gail says
I think I’ll make this and put it in my crock pot so we’ll have something to eat when we finish our Christmas Eve service just in case anyone is hungry. Thanks for that reminder. Love this soup.
Ann says
Yeah this is a good one, Gail! I was shocked I liked it so much, as leeks aren’t really one of my favorite foods. I am so glad you enjoy it too!
