Ingredients:
- 1 tablespoon olive oil
- 1 medium onion, finely diced (about 1 cup diced) (Approximately 150g)
- 1 medium leek, sliced thinly (white and light green parts only, about 1 cup sliced) (Approximately 100g)
- 3 medium carrots, sliced (no need to peel) (Approximately 200g)
- 2 sticks celery, sliced (Approximately 100g)
- 1 small parsnip, peeled and sliced (Approximately 75g)
- 1 medium potato, peeled and chopped into 1cm / ½ inch cubes (Approximately 200g)
- 500 ml (2 cups) vegetable stock (made with a cube is fine, good quality stock recommended)
- Salt and freshly ground black pepper, to taste
Instructions:
- Heat the olive oil in the saucepan over low heat. Add the diced onion and sliced leek. Cover and cook, stirring occasionally, until softened (about 5 minutes). Don't let them brown!
- Add the sliced carrots, celery, parsnip, and chopped potato to the saucepan. Stir well to combine.
- Pour in the vegetable stock. Season with salt and pepper to taste. Bring the mixture to a boil, then reduce heat to low. Cover and simmer for 15 minutes, or until all the vegetables are completely tender and easily pierced with a fork.
- Remove the saucepan from the heat. Use an immersion blender to blitz the soup until smooth. If using a regular blender, carefully transfer the hot soup in batches to the blender and blend until smooth (be careful of steam!).
- If the soup is too thick, add a little extra boiling water from a kettle until it reaches your desired consistency. Taste the soup and add more salt and/or pepper, if needed.
- Ladle the soup into bowls and serve immediately.
