Ingredients

For the Soup:

  • 200 g watercress
  • 4 small new potatoes, peeled and diced
  • 3 cups 750ml vegetable stock
  • 2 stalks of celery, chopped
  • 2 cloves garlic, minced
  • 1 small onion, chopped
  • 1 sprig of thyme
  • 1 lemon, juice only

For Garnish:

  • Small potato, diced and pan-fried
  • Croutons
  • Lemon pepper vegan yogurt
  • Olive oil

Instructions

  • Heat 1 tablespoon of olive oil in a medium-sized pot over medium heat.
  • Add the onion and garlic to the pot. Sauté until they become fragrant and translucent.
  • Stir in the celery and thyme, and cook for an additional minute.
  • Pour in the vegetable stock and bring the mixture to a boil.
  • Once boiling, add the diced potatoes and cook until they are tender, about 15 minutes.
  • Add the watercress to the pot and boil for 2 more minutes.
  • Carefully transfer the soup mixture to a blender. Blend until it becomes a smooth and creamy soup. *You can leave the soup in the pot and use an immersion/ stick blender to blend the soup.
    Taste and adjust the seasoning and add in the lemon juice. *Start with the juice from ½ the lemon and add more if desired.
  • In a separate pan, fry the diced potato for garnish until golden and cooked through. *This is optional.
  • Serve the soup in bowls, topped with fried potato dices, croutons, and a dollop of lemon pepper vegan yogurt. Drizzle with a bit of olive oil for an extra touch.

Notes

  • For a smoother soup, strain it through a sieve after blending.
  • If you prefer a thinner consistency, adjust by adding a bit more vegetable stock.
  • Always be cautious when blending hot liquids; start at a low speed and increase gradually.
  • The lemon pepper vegan yogurt adds a zesty twist, but you can substitute it with plain vegan yogurt if preferred.
