A leek is a vegetable that looks like a really huge green onion. It is related to garlic, onions and shallots, which makes sense because it tastes like a very mild onion. It is the perfect addition to a Potato Soup! You can find them in just about any grocery store.
To learn more about leeks, you can pop over to this article All About Leeks from Spruce Eats.
Leeks are grown in very sandy soil so they have a tendency to be sandy and dirty through all their layers. To prepare, trim the root end and the dark green stems and discard. Split the remaining white and light green part of the leek in half lengthwise and run under water splitting the layers open with your fingers.
How to Make Potato Leek Soup
- Sauté Leeks
- Add seasonings and potatoes
- Add liquid and simmer.
Start with your pot over medium heat and melt the butter. Add the sliced leeks and saute until they are wilted, about 5 minutes.
Add the garlic and saute another 2 minutes.
Stir in the season salt, pepper, dried basil, bay leaves, chicken base and chopped potatoes.
Pour in the chicken broth and water. Increase the heat to medium high and simmer for 20 minutes. If it starts to boil turn the heat back to medium.
Once the potatoes are fork tender lower the heat back to low. Remove the bay leaves and discard.
This next part is completely up to personal preference…. do you want your soup silky, chunky, semi chunky?
With a slotted spoon remove as much of the potatoes and leeks as you can, place in a blender or food processor. Add enough liquid from the soup so that the solids will process smooth. Add the puree back to the soup and stir.
Tip: Be careful when you blend hot food, leave room in the blender do not fill it to the top and vent the blender or processor.
This is usually how I make my soup…
Take a hand held potato masher and mash all the large chunks right in the pot. You will basically be making smaller chunks… so a mix of chunky and silky.
Using a wooden spoon lightly mash about half of the potatoes right in the pot and stir the mash into the soup.
Finishing the Soup
To finish the soup stir in the cream, sour cream, and parmesan cheese until it is completely melted in and incorporated.
Let it cool for a few minutes, taste for seasonings, and serve!
To make a white swirl garnish like in the photos thin a little sour cream with milk or cream, until it is a drizzle consistency.
This Potato Leek Soup will thicken in the fridge. So when you are reheating you may need to add a little milk or broth to reconstitute the soup.
Make It A Meal
This Potato Leek Soup is pretty filling on its own, so it really just needs a dipper. Some warm crusty bread will do nicely!
