What is Watercress Soup?
Watercress soup is a velvety blend of watercress, potatoes, and onions, simmered until tender and pureed to create a smooth texture.
The soup is not merely a combination of ingredients; it tells a story of fresh, seasonal produce and simple cooking methods that yield extraordinary flavors. Originating from European cuisine, it can be a standalone dish or a lovely starter.
What is the Flavor Profile of This Dish?
The flavor profile of watercress soup can be described as bright, fresh, and slightly peppery. The watercress contributes a vibrant, leafy taste, while the potatoes add creaminess. The onions bring sweetness and depth, while a hint of nutmeg warms the dish up, grounding it in comfort.
If you decide to finish it with a dollop of sour cream, that tang adds a delicious contrast, making each spoonful a delightful experience.
What Makes This Recipe Different from Other Watercress Soup Recipes?
What sets my watercress soup apart from others is a distinct balance of flavors and textures. Many recipes may lean heavily on cream, making them overly rich. In my version, the natural creaminess comes from the potatoes, while a bit of white wine adds acidity and depth.
The focus remains on the freshness of the watercress, allowing its unique flavor to shine through. Trust me; this is a soup that makes you feel good while tasting extraordinary.
Ingredients You’ll Need
To create this delightful watercress soup, gather the following ingredients:
- 6 cups filtered water – for the base of your soup
- 1 pound peeled potatoes, cut into chunks – for creaminess
- 2 cups chopped white or yellow onions – for sweetness and depth
- 1 cup dry white wine, chicken broth, or vegetable broth – pick wine or vegetable broth for a vegetarian option
- 3 tablespoons unsalted butter – for richness
- 6 cups chopped fresh watercress (about 1/2 pound), including stems – the star ingredient!
- 1/2 teaspoon lemon zest – for brightening the flavors
- 1/4 teaspoon nutmeg – for warmth
- Salt, to taste
- 1/2 teaspoon freshly ground black pepper – for spice
- About 6 tablespoons sour cream, stirred in or used as garnish – for a creamy finish

Step-by-Step Directions
Step 1: Prepare the Base
Start by heating the unsalted butter in a large pot over medium heat. Add the chopped onions and cook until they are soft and translucent; this should take around 5-7 minutes. Stir occasionally to avoid browning.
Step 2: Add Potatoes and Broth
Next, toss in the potato chunks. Stir them into the onions, allowing them to mingle for a couple of minutes. Pour in the white wine or your choice of broth. Bring the mixture to a boil, then reduce it to a gentle simmer. Cook until the potatoes are fork-tender, roughly 15-20 minutes.
Step 3: Incorporate the Watercress
Once the potatoes are soft, add the watercress, lemon zest, nutmeg, salt, and black pepper. Allow everything to simmer together for about 5-7 minutes. The watercress will wilt down but retain its vibrant green color.
Step 4: Blending to Perfection
Now comes the fun part! Using an immersion blender, puree the soup until it’s smooth and silky. If you don’t have one, you can carefully transfer the soup in batches to a standard blender but be cautious with the heat.
Step 5: Final Touches
Once blended, taste for seasoning. Adjust salt and pepper as needed. If desired, you can also stir in the sour cream for creaminess or serve it as a garnish on top of the soup.

- Adjusting Thickness: If the soup is too thick, add more broth or water until you reach your desired consistency.
- Serve with Flair: Garnish with a sprinkle of fresh herbs or a drizzle of olive oil for a gourmet touch.

- Broth: If you lack broth or wine, water can work in a pinch, but you may need to add more seasoning to compensate.
