This comforting potato leek soup is perfect for a cozy night in. The creamy texture and rich flavors make it a delightful starter or a satisfying main course. With simple ingredients and straightforward steps, this recipe is a must-try for anyone looking to enjoy a warm, homemade soup.
While most of the ingredients for this potato leek soup are common, you might need to pay special attention to leeks. They are not as commonly found in every household as potatoes or butter. When shopping, look for fresh, firm leeks with bright green tops and white bottoms. Make sure to clean them thoroughly to remove any dirt or grit.

Ingredients for Potato Leek Soup
Potatoes: These form the base of the soup, providing a creamy and hearty texture.
Leeks: These add a subtle onion-like flavor that complements the potatoes perfectly.
Chicken broth: This serves as the liquid base, adding depth and richness to the soup.
Heavy cream: This ingredient adds a luxurious creaminess to the soup, making it rich and smooth.
Butter: Used for sautéing the leeks, it adds a rich, buttery flavor to the soup.
Salt: Essential for seasoning and enhancing the flavors of the soup.
Pepper: Adds a bit of heat and complexity to the flavor profile.
Technique Tip for This Recipe
When preparing leeks, make sure to clean them thoroughly. Leeks can trap a lot of dirt and sand between their layers. Slice them lengthwise and rinse under cold running water, separating the layers to remove any hidden grit. This ensures your soup remains smooth and free from any unwanted texture.

How To Store / Freeze This Soup
Allow the potato leek soup to cool completely before storing. This helps to 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 to keep track of freshness. This is especially useful if you plan to store the soup for an extended period.
Store the soup in the refrigerator if you plan to consume it within 3-4 days. The heavy cream in the soup can spoil if left for too long.
For longer storage, place the airtight containers in the freezer. The soup can be frozen for up to 3 months without losing its flavor and texture.
When ready to enjoy, thaw the frozen soup in the refrigerator overnight. This gradual thawing helps maintain the soup's creamy consistency.
Reheat the soup gently on the stovetop over medium heat, stirring occasionally to prevent scorching. Avoid boiling, as this can cause the heavy cream to separate.
If the soup appears too thick after reheating, add a splash of chicken broth or water to reach the desired consistency.
Taste and adjust the seasoning with salt and pepper before serving, as freezing can sometimes dull the flavors.
Garnish with fresh herbs like chives or parsley for a burst of color and added flavor.
