Spiced Carrot and Lentil Soup
Equipment
- Blender or immersion blender.
Ingredients
- 1 tablespoon olive oil
- 1 onion, peeled and sliced
- 2 garlic cloves, peeled and sliced
- 1 tablespoon curry powder
- 1 teaspoon ground cumin
- 600 g carrots, cut into rounds
- 140 g dried red lentils
- 1 litre vegetable stock, low sodium, note 1
Toppings (optional)
- 1 teaspoon chilli flakes
- a few sprigs of parsley
Instructions
- Heat the olive oil in a large pan over medium heat. Add the onion and garlic and saute for 5 minutes until soft. Add the curry powder and cumin and stir for 30 seconds (this helps release the spices).
- Stir in the carrots and red lentils, followed by the vegetable stock. Bring the vegetables to a boil, then reduce the heat to low. Let it simmer gently for 15-20 minutes, uncovered, until the lentils are tender and the carrots are soft. If needed, extend the cooking time by a few minutes until both are fully cooked.
- Allow the carrot lentil mixture to cool, then transfer it to a blender and blend until smooth. Depending on the size of your blender, you may need to do this in batches. Alternatively, you could use an immersion blender.
- Return the soup to the pan and heat it thoroughly before serving. Taste test for seasoning. Ladle into bowls and serve with warm, crusty bread and optional toppings like parsley and chilli flakes.
