    🥘 A Cozy & Comforting Soup

    With just six ingredients, you cannot go wrong on a cool fall or winter day with this simple yet delectable soup.

    This potato and leek soup recipe adds texture with the simple to make frizzled leeks and a chicken broth adds depth of flavor to this veggie heavy dish.

    It's a great way to warm your home and keep everyone full and coming back for seconds. As with most homemade soup recipes, it is easy to prepare, then keep warm until you are ready to serve.

    I also make these hot soups that I think you'll love: red lentil and dill soup, mango soup and homemade roasted tomato soup.

    🥔 Ingredients

    Leek potato soup ingredients labeled.
    • large leeks - As seen in the picture above, leeks have a long, cylindrical shape with a white base and green, leafy tops. They have a mild, sweet, and onion-like flavor, but they are less pungent than onions.
    • canola oil - To fry the leek topping.
    • yellow onions - The flavor of onions deepens as they cook, adding a rich, comforting base to the potato soup.
    • garlic cloves - Garlic blends well with the soup and adds rich, aromatic flavor that complements the potatoes.
    • chicken broth - Looking for a vegetarian or vegan option? There is no cream in this recipe so it can easily be modified with a vegetable based broth to make it vegan-friendly.
    • Yukon Gold potatoes - (Also known as yellow potatoes.) Yukon Gold potatoes have a thin skin and so peeling them is optional. You can try using different types of potatoes to vary the soup from one batch to another. I personally like the yellow (Yukon Gold) potato variety and use it in most of my recipes (such as this potato galette). Russets are an easy choice for this soup as well.

    🔪 How to Make Leek and Potato Soup

    For the Soup

    Sliced leeks in bowl of cold water.

    Step 1. Prep the Leeks. Remove the roots, outer leaves, and tops from the leeks. Thinly slice the white and light green parts of the leek. Rinse in a bowl of cold water and then drain.

    Step 2. Cook Leeks. Heat oil in a large saucepan over medium heat. Add the leeks, onions and garlic. Mix them around in the oil and then lower the heat to medium-low. Partially cover, and cook for 15 minutes, stirring occasionally.

    For the Frizzled Leeks

    Sliced, cleaned leeks in colander.

    Step 1. Clean Leeks. Remove the roots, outer leaves, and top from the leek. Cut it in half lengthwise and then into slices. Rinse them in a bowl of water to remove any dirt. Drain and pat dry.

    Step 2. Fry the Leeks. In a small non-stick frying pan, heat the canola oil over medium-high heat. Add the leeks to the oil. Fry the leeks, stirring constantly, until the leeks are golden brown (about 5 to 7 minutes).

    Chef's Note: For the frizzled leeks, instead of slicing them width-wise, you can also choose to slice them into 3" long strips.

    Step 3. Remove Oil. Remove the frizzled leaks to a bowl with paper towel to remove excess oil. Use them as a topping for the soup.

    ✔️ Joss' Tips

    • This soup also makes for great leftovers and reheats well. If you ended up freezing your soup, thaw it in the fridge overnight before you reheat it on the stove.
    • Make sure you clean the leeks very well so that you aren't left with a gritty soup from the dirt that ends up caught between the layers.
    • The frizzled leeks add a full-bodied flavor to the puréed soup; just consider making a fresh batch of frizzled leeks when preparing on day two or three. They can also make a great topping for salads.

    🍞 Side Suggestions

    Here is a list of some great side dish options for your soup.

    • Bread: Toast points, crusty bread, garlic bread, bread sticks, pretzel rolls etc.
    • Salads: Green salad, Caesar salad, hemp seed salad and spinach salad.
    • Sandwiches: Kimchi grilled cheese sandwiches, blackened chicken sandwich, turkey or ham sandwiches and paninis.
    • Proteins: Roasted chicken or bacon bits.
    • Drinks: White wine such as sauvignon blanc, herbal tea or sparkling water.

    ❓ Recipe FAQs

    How long do leftovers last in the fridge?

    The soup can be stored in the fridge in an airtight container for up to 5 days.

    Can you freezer leftover potato and leek soup?

    Yes! It can be stored in the freezer for up to 6 months, but make sure it cools down first.

    Why does my leek and potato soup taste bitter?

    Leeks can develop bitterness if they are overcooked or exposed to high temperatures. Also, using the green sections of the leek, which are tougher and more intense in flavor, can also cause some bitterness.

    Why is my potato leek soup gummy?

    Potatoes, if over-mashed or over-blended, release their starches and this results in a sticky, gluey texture. Blend until they are just so smooth, then stop to avoid a gloopy mess.

    What if my leek and potato soup is too thick?

    If it's too thick after you've puréed it, simply add some more broth until it's the right consistency for you and let it reheat.
