Let’s Talk Leeks! (Cleaning and Prep Tips)
Okay, friend, before we dive into the nitty-gritty of soup-making, let’s address the elephant in the room: leeks. These lovely, onion-y vegetables can be a bit… sandy. They grow in sandy soil, and that sand LOVES to hide between their layers. Don’t skip this step – properly cleaned leeks are essential for a delightful Potato Leek Soup experience! Here’s my foolproof method:
1. Slice it up: Cut off the dark green, tough tops of the leeks (save these for making stock!). Then, slice the white and light green parts lengthwise, all the way to the root end, but don’t cut through the root. This will allow you to fan out the layers.
2. Submerge and Swish: Place the sliced leeks in a large bowl filled with cold water. Use your hands to swish them around vigorously, separating the layers and dislodging any dirt or sand.
3. Lift and Rinse: Let the leeks sit for a minute or two, allowing the sand to settle at the bottom of the bowl. Then, carefully lift the leeks out of the water, leaving the sandy water behind. Rinse the leeks under cold running water, paying attention to each layer.
4. Repeat if Necessary: If you see any remaining grit, repeat the process until the leeks are squeaky clean.
5. Slice and Dice: Once cleaned, thinly slice the leeks crosswise. Now they are ready to add to your soup.
Step-by-Step Instructions
Alright, are you ready to make some magic? This Potato Leek Soup recipe is truly simple, and I’m here to guide you through every step. Don’t worry; even if you’re a beginner cook, you’ve got this!Sauté the Aromatics
- Heat the olive oil in a large pot or Dutch oven over medium heat.
- Add the sliced leeks, garlic, thyme, salt, and pepper. Cook, stirring occasionally, until the leeks are softened and translucent, about 8-10 minutes. Be careful not to brown them – you want them to be sweet and mild!
Simmer the Soup
- Pour in the vegetable broth (or chicken broth) and add the cubed potatoes. Bring to a boil, then reduce heat and simmer until the potatoes are tender, about 15-20 minutes. You should easily be able to pierce a potato cube with a fork.
Blend to Creamy Perfection
- This is where the magic happens! Carefully transfer the soup to a blender in batches (don’t overfill the blender – hot liquids can expand and cause a mess!). Alternatively, use an immersion blender to blend the soup directly in the pot.
- Blend until smooth and creamy. Be careful when blending hot liquids! Start on a low speed and gradually increase to high. If using a regular blender, vent the lid slightly to allow steam to escape.
Finish and Serve
- Return the blended soup to the pot. Stir in the heavy cream (or half-and-half) and heat through gently. Do not boil!
- Taste and adjust seasoning as needed. Add more salt and pepper to your liking.
- Ladle the soup into bowls and garnish with your favorite toppings, such as fresh chives, crispy bacon crumbles, a dollop of sour cream or Greek yogurt, croutons, or a drizzle of olive oil.
- Serve immediately and enjoy your homemade Potato Leek Soup!
Troubleshooting and Expert Tips
Okay, let’s be real. Sometimes things don’t go exactly as planned in the kitchen. But don’t worry, I’m here to help you troubleshoot any potential issues and share some insider tips for the best possible Potato Leek Soup:- Soup Too Thick? If your soup is too thick, simply add a little more broth until you reach your desired consistency.
- Soup Too Thin? If your soup is too thin, you can either simmer it uncovered for a bit longer to allow some of the liquid to evaporate, or you can mix a tablespoon of cornstarch with a tablespoon of cold water to form a slurry, then whisk it into the soup and simmer for a few minutes until it thickens.
- Leeks Browning? If your leeks start to brown while sautéing, reduce the heat slightly and add a tablespoon of water or broth to the pot. This will help to prevent them from burning.
- Don’t Overcook the Potatoes: Overcooked potatoes can make your soup gummy. Cook them just until they are tender.
- Immersion Blender Tip: When using an immersion blender, start with the blender submerged in the soup before turning it on. This will prevent splattering.
- Make it Vegan: To make this soup vegan, use vegetable broth and substitute the heavy cream with full-fat coconut milk or cashew cream.
- Spice it Up: For a little extra flavor, add a pinch of red pepper flakes or a dash of hot sauce to the soup.
Variations to Make it Your Own
The beauty of soup is that it’s so adaptable! Feel free to experiment and make this Potato Leek Soup your own. Here are a few ideas to get you started:- Add Some Protein: Stir in some cooked chicken, sausage, or ham for a heartier soup. You could even add some chickpeas or white beans for a vegetarian protein boost.
- Roast the Vegetables: Roasting the leeks and potatoes before adding them to the soup will deepen their flavor and add a touch of caramelized sweetness.
- Add Different Herbs: Experiment with different herbs, such as rosemary, sage, or parsley.
- Make it Cheesy: Add a cup of shredded cheddar cheese or Gruyere cheese to the soup after blending for a cheesy twist.
- Add a Swirl of Pesto: A swirl of pesto adds a burst of fresh, herby flavor to the soup.
- Garlic Lovers Unite: If you are a garlic lover, you might enjoy my French Garlic Soup! The flavors are very unique.

- Reheating: Reheat the soup in a saucepan over medium heat, stirring occasionally, until heated through. You can also reheat it in the microwave in 1-2 minute intervals, stirring in between.
