For 4 servings
Prepare your ingredients: Wash the watercress thoroughly, remove any thick, tough stems, and roughly chop the leaves and tender stems. Peel and dice the potato into 1/2-inch pieces. Chop the onion.
In a large pot or Dutch oven, heat the olive oil over medium heat. Add the chopped onion and sauté for 5-7 minutes, stirring occasionally, until softened and translucent.
Add the diced potato and vegetable broth to the pot. Bring the mixture to a boil, then reduce the heat to low, cover, and simmer for 10-15 minutes, or until the potato pieces are fork-tender.
Stir in the chopped watercress. Cook for just 1-2 minutes, or until the watercress has wilted and turned a vibrant green. Do not overcook, as this can dull the color and flavor.
Carefully transfer the soup to a blender, or use an immersion blender directly in the pot. Blend until completely smooth and creamy. If using a regular blender, work in batches and ensure the lid is vented to release steam, covering with a kitchen towel.
Return the blended soup to the pot (if using a regular blender). Season with salt and black pepper to taste. Reheat gently if necessary, but do not boil.
Ladle the hot soup into bowls. Garnish with a sprinkle of fresh chives or a drizzle of olive oil, if desired, and serve immediately.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1To maintain the vibrant green color and peppery flavor, add the watercress at the very end of the cooking process and blend immediately after it wilts.
- 2An immersion blender makes blending incredibly easy and mess-free, allowing you to blend directly in the pot.
- 3If your soup is too thick, you can thin it out with a little extra vegetable broth or water until it reaches your desired consistency.
- 4For an extra layer of flavor, consider adding a pinch of nutmeg or a bay leaf to the broth while the potatoes are simmering, removing the bay leaf before blending.
