How to Make Celery Leek Soup
This Celery Leek Soup is your new go-to for a quick, satisfying, and incredibly flavorful meal. Its beauty lies in its simplicity, requiring minimal effort for maximum taste and a luxuriously smooth texture. With just a 15-minute prep time and 30 minutes of cooking, you can enjoy a bowl of pure comfort in under an hour.
Step-by-Step Instructions
- Sauté the Aromatics: In a large pot or Dutch oven, heat the olive oil and butter over medium heat. Once the butter has melted and is shimmering, add the sliced leeks, chopped celery, and chopped onion. Cook, stirring occasionally, until the vegetables have softened, which should take about 8-10 minutes. Be careful not to brown them too much; we’re aiming for tender and translucent.
- Add the Garlic and Thyme: Stir in the minced garlic and fresh thyme leaves (if using dried, you can add it later with the broth). Cook for another minute until the garlic is fragrant. This step awakens the aromatic qualities of the ingredients.
- Simmer the Soup: Pour in the vegetable broth and bring the mixture to a boil. Once boiling, reduce the heat to low, cover the pot, and let it simmer gently for about 15-20 minutes, or until the celery is very tender. This simmering time allows the flavors to meld beautifully.
- Blend to Creamy Perfection: Carefully transfer the soup, in batches if necessary, to a blender or use an immersion blender directly in the pot. Blend until the soup is completely smooth and creamy. If using a standard blender, be cautious when blending hot liquids, and do not overfill the blender jar.
- Incorporate the Cream and Season: Return the blended soup to the pot (if you used a standard blender). Stir in the heavy cream (or milk). Heat the soup gently over low heat, but do not let it boil. This is also the time to add dried thyme if you didn’t use fresh earlier.
- Season and Serve: Season the Celery Leek Soup generously with salt and freshly ground black pepper to taste. Adjust seasoning as needed. Ladle the warm soup into bowls and garnish with fresh chives, croutons, or a swirl of cream or olive oil, if desired.

Storing and Reheating Tips
Proper storage will ensure your delicious Celery Leek Soup remains a delightful treat for days to come.
- Refrigeration: Allow the soup to cool to room temperature before transferring it to an airtight container. Refrigerated, the soup will stay fresh for up to 3-4 days.
- Freezing: For longer storage, freeze the soup in freezer-safe containers or heavy-duty freezer bags. Ensure it is completely cooled before freezing. Frozen Celery Leek Soup can be kept for up to 2-3 months. It’s best to freeze it before adding the cream, if possible, as cream can sometimes separate slightly upon thawing and reheating. If you freeze it with the cream, it will still be delicious, but a quick stir might be needed.
- Reheating: To reheat refrigerated soup, gently warm it in a saucepan over low to medium heat, stirring occasionally, until heated through. Do not boil. If reheating from frozen, thaw the soup overnight in the refrigerator and then reheat as above. Alternatively, you can reheat frozen portions in a microwave-safe dish on a lower power setting, stirring every so often, until fully heated. Be patient to retain the creamy texture.
