I love making this potato leek soup because it feels like a warm hug on a chilly day. It’s simple but so comforting, and the creamy texture always makes me smile. I hope you enjoy making it as much as I do!
Leeks might be a new ingredient for some, but they are easy to find in most supermarkets near the onions or green vegetables. Just make sure to clean them well since dirt can hide between the layers. If you don’t have heavy cream, you can use a milder milk or a cream substitute, but the soup will be extra creamy with the real thing.
Ingredients For Potato Leek Soup Recipe
Potatoes: These are the main part of the soup and give it a thick, hearty texture.
Leeks: Mild and slightly sweet, they add a fresh onion-like flavor without being too strong.
Chicken or vegetable broth: This is the liquid base that cooks the potatoes and leeks and adds flavor.
Heavy cream: Adds richness and creaminess to the soup.
Butter: Used to cook the leeks and adds a smooth, buttery taste.
Salt and pepper: Basic seasonings to bring out all the flavors.
Technique Tip for This Recipe
One of the key steps in this Potato Leek Soup Recipe is cooking the leeks until they’re soft before adding the potatoes and broth. Here’s how to do it just right:
- Start by melting the butter in a large pot over medium heat. You want the butter to be melted but not browned or burnt.
- Add the cleaned and sliced leeks to the pot. Spread them out so they cook evenly.
- Stir the leeks gently every minute or so. This helps them cook without sticking or burning.
- Keep cooking the leeks for about 5 minutes until they become soft and a little translucent. They should smell sweet and mild, not sharp or raw.
Cooking the leeks slowly like this is a game changer because it brings out their natural sweetness and makes the soup taste richer. If you rush this step or cook them too fast on high heat, the leeks might burn or taste bitter, which can affect the whole soup.
When I first made this soup, I didn’t cook the leeks long enough and the soup ended up tasting a bit sharp and raw. After I learned to be patient and soften them gently, the flavor became so much better. Also, if you want to save time, you can slice the leeks thinner so they cook faster, but just watch them closely so they don’t burn.
Taking a few extra minutes to cook the leeks well makes the whole soup smoother and yummier. It’s a small step that really pays off!

How to Store or Freeze This Soup
Allow the potato leek soup to cool completely before storing. This helps prevent condensation, which can lead to a watery soup.
Transfer the cooled soup into airtight containers. For easy portioning, consider using individual serving-sized containers.
Label the containers with the date of preparation. This ensures you keep track of freshness and consume the soup within a safe timeframe.
Store the containers in the refrigerator if you plan to consume the soup within 3-4 days. The heavy cream in the soup can spoil if left too long, so timely consumption is key.
For longer storage, place the airtight containers in the freezer. The soup can be frozen for up to 3 months without significant loss of flavor or texture.
When ready to reheat, thaw the soup in the refrigerator overnight if frozen. This gradual thawing helps maintain the soup's creamy consistency.
Reheat the soup on the stove over medium heat, stirring occasionally to prevent scorching. Avoid bringing the soup to a boil, as this can cause the heavy cream to separate.
If the soup appears too thick after reheating, add a splash of chicken broth or vegetable broth to reach the desired consistency.
Garnish with fresh chives or a sprinkle of black pepper before serving to enhance the flavor and presentation.
How to Reheat Leftovers
On the stovetop: Pour the potato leek soup into a saucepan. Heat over medium-low, stirring occasionally, until warmed through. This method helps retain the creamy texture and ensures even heating.
In the microwave: Transfer a portion of the soup to a microwave-safe bowl. Cover with a microwave-safe lid or plastic wrap, leaving a small vent. Heat on medium power in 1-minute intervals, stirring in between, until hot. Be cautious not to overheat, as the cream can curdle.
In a slow cooker: Pour the leftover soup into the slow cooker. Set to low and heat for 1-2 hours, stirring occasionally. This method is perfect for reheating larger quantities without constant attention.
Using a double boiler: Fill the bottom pot of a double boiler with water and bring to a simmer. Place the soup in the top pot and heat, stirring occasionally, until warmed through. This gentle method prevents scorching and maintains the soup's creamy consistency.
Essential Tools for This Recipe
Large pot: A deep pot used for cooking the soup, allowing enough space for all ingredients to simmer together.
Wooden spoon: Ideal for stirring the leeks and other ingredients without scratching the pot.
Blender: Used to puree the soup until smooth, ensuring a creamy texture.
Knife: Essential for peeling and dicing the potatoes and slicing the leeks.
Cutting board: Provides a safe and stable surface for chopping the vegetables.

Measuring spoons: Necessary for measuring the butter and any additional seasonings.
Ladle: Handy for serving the soup into bowls.
Soup bowls: Used to serve the finished soup.
Chive scissors: Optional, but useful for finely chopping chives if you choose to garnish the soup.
Time-Saving Tips for This Recipe
Prep ingredients in advance: Peel and dice potatoes and slice leeks the night before to save time.
Use pre-made broth: Opt for store-bought chicken or vegetable broth to cut down on preparation time.
Immersion blender: Use an immersion blender directly in the pot to puree the soup, avoiding the need to transfer to a blender.
Quick soften leeks: Microwave leeks for a couple of minutes before adding to the pot to speed up the cooking process.
