Potato Leek Soup Recipe (1)

Creamy Potato Leek Soup

This potato leek soup is the kind of soup that is so simple to make yet tastes like you really know your way around the kitchen. I grew up loving this classic soup as a kid, and eating it always brings me back to a happy place. Because I grew up with my parents cooking soup from scratch, I have a ton of soup recipes!

Potato Leek Soup Recipe (2)

I always think of my childhood when I eat a bowl of potato leek soup. Since my parents made soup for dinner as a starter or main dish almost daily, I certainly had my fair share of soup. The soups I enjoyed most as a kid, were the purees, as I was pretty picky. On nights we had potato leek soup, I never complained though, and still to this day crave this soup when the weather gets cold.

Potato Soup Ingredients

  • Onions and Leeks: Use 4 medium leeks with dark green stems removed and 1/2 large white onion, chopped
  • Potatoes: Use 2 medium russet or Yukon gold potatoes, peeled and cut into cubes
  • Roux: 1 tablespoon all purpose flour or use gluten free flour such as Cup4Cup and salted butter
  • Broth: Use 4 cups chicken broth, or use vegetable broth for vegetarians
  • Milk: 1/2 cup 2% milk or dairy-free milk of choice
  • Fresh Chives, optional for garnish
  • Salt and fresh pepper, to taste

How To Make Potato Leek Soup

Once you clean the leeks, making potato leek soup is easy!

  1. Roughly chop the leeks.
  2. Add butter and flour to a heavy pot or Dutch oven to make a roux.
  3. Then add leeks, onion, chicken stock and potatoes and simmer until the potatoes are tender.
  4. Then blend the soup with an immersion blender or if you wish, a regular blender in batches until smooth.

Tips and Variations

Potato leek soup is simple to make, the mild flavors of leeks and the potatoes compliment each other so well. Although I like mine pureed, if you prefer yours with a chunky texture you can use a potato masher instead of an immersion blender to give you bigger chunks.

  • Gluten Free –Use an all purpose gluten-free flour mix in place of wheat such as Bobs Redmill or Cup4Cup.
  • Dairy Free – If you wish to make it dairy free, simply leave the milk out and add more broth.
  • Cheese: Add some shredded cheddar cheese on top
  • Vegan: Swap milk for dairy-free milk and use vegetable broth
  • Add herbs: Use bay leaves or thyme sprigs to the pot while cooking for extra flavor
  • Storage –Refrigerate in an airtight container for up to 4 days or in the freezer for up to 3 months. To reheat, thaw overnight in the refrigerator then reheat on the stove or in the microwave.

How To Clean Leeks

The most important thing to know about making this soup is how to clean the leeks. They’re sandy and dirty, and hide it pretty well, so be sure to wash them well.

  1. First step is cutting off and discarding the root ends and thick dark green parts.
  2. Then cut the leeks in half lengthwise and rinse each half under cold water, pulling apart the layers to remove any grit that’s tucked inside.
  3. Once clean, you can proceed to chop them.

Potato Leek Soup Recipe (2024)

FAQs

What was Julia Child's favorite soup? ›

Soup was one of Julia Child's favorite things to eat, and reportedly, her absolute favorite was vichyssoise. Leek and potato soup, known as potage parmentier in French, is a classic base soup recipe. What sets vichyssoise apart is the addition of cream—and the fact that it is traditionally served chilled.

Why is my potato leek soup gluey? ›

If the potatoes are pulverized too thoroughly, they will leach gelatinized starch into the broth. This starch will bond with the broth, causing the body of the soup to become slimy.

Why is leek and potato soup good for you? ›

Allicin, one of these sulfur compounds, neutralizes free radicals. Hence, it makes leeks a potent anti-inflammatory food. Allicin also protects us against viruses and cancer and supports heart health. Leeks are high in inulin, a soluble fiber that benefits our colon health.

What goes good with leek and potato soup? ›

Potato Leek Soup Serving Suggestions

Jack and I often enjoy this potato and leek soup on its own, with good crusty bread, homemade focaccia, or dinner rolls on the side. If you're craving a larger meal, I recommend pairing it with a salad.

What is Julia Child's most famous dish? ›

Child's Boeuf Bourguignon recipe was featured in one of the earliest episodes of The French Chef and has become a classic among the many Child enthusiasts at GBH. In fact, GBH News host Henry Santoro concludes there's no better recipe for the dish.

What is Julia Child's favorite meal? ›

Vichyssoise. Well-known as one of Julia Child's favorite dishes, this chilled leek and potato soup is startling in its simplicity. Aside from the leek, potato, and water, Child's version of the soup calls for barely any additional ingredients.

Why does my leek and potato soup taste bitter? ›

Add the leeks to the pot, lowering the heat if necessary and saute for 10-15 minutes , or until soft and translucent. Be careful not to burn the leeks, as they will impart a bitter taste to the soup. The excess liquid from cleaning the leeks should help prevent any burning.

Why has my leek and potato soup gone brown? ›

It looks as though some of your potatoes might have got a bit scorched. Did you fry them off before adding the liquid? The colour from the browned potatoes could be what is turning it brown.

Should I cook potatoes before adding to soup? ›

There's no correct way but some methods provide difference outcomes. I normally dice my potatoes quite small, boil them on their own and add to the soup at the end. That way they are perfectly cooked. On the other hand you can add them with other vegetables and the potatoes will begin to crumble once they are cooked.

Is it OK to eat leeks everyday? ›

Leeks are a healthy food and, like most foods, can be eaten in moderation as part of a balanced diet. Eating large amounts of leeks, however, can have some negative effects. First, leeks are high in fiber and can cause digestive discomfort, bloating, and gas if consumed in large amounts.

Are leeks better than onions in soup? ›

Leeks have a more subtle, slightly sweeter flavor than onions. So you would use them when you want some onion flavor, but don't want it to fight with the rest of the ingredients. One of my favorite examples of this is soup made with leeks, potatoes and cod, in fish stock, finished with cream or half and half.

Are leeks anti-inflammatory? ›

Leeks have a variety of biological active effects, such as anti-cancer, anti-inflammation, anti-obesity, anti-oxidation and anti-bacteria, but the action mechanisms of these biological effects are still unclear.

How can I thicken my leek and potato soup? ›

Add flour or cornflour

Put a tablespoon of either into a small bowl and stir in 2-3 tbsp of the soup until you have a smooth mixture. Stir this back into the soup and bring it to a simmer. Cook for a few minutes to allow the starch granules to burst to thicken, and to cook out any flour flavour.

Can you leave potato and leek soup out overnight? ›

It's really not a good idea to leave it out at room temperature. I've left stock on the stove overnight at a simmer with the lid on. This keeps it hot enough that microbes won't grow but traps evaporation so it can't go dry. It is ok to put the soup in the refrigerator in a fresh room temperature container, covered.

Is it OK to reheat leek and potato soup? ›

Reheat the soup to a gentle simmer (add some extra stock at this point if the soup is too thick for your liking), then pour into warmed bowls. Drizzle the remaining cream over each serving, top with a little pile of buttered leeks and a scattering of chives and black pepper and serve at once.

Boeuf Bourguignon

This hearty beef stew from the pages of "Mastering the Art of French Cooking" is, hands down, Child's most infamous dish. (Click here for Food.com's rendtition of boeuf bourguignon.)

What was Julia Child's favorite cake? ›

By Nigella Lawson. Julia Child wrote that the Gateau Reine de Saba was the first French cake she ever ate. My version is a bit simpler to make than hers. I melt the chocolate with liquid, and I use all ground almonds rather than the traditional mixture of flour and almonds.

What food did Julia eat for the first time? ›
