Spicy Tomato and Lentil Soup
Serves 4
  • ¾ cup (175ml) of uncooked red lentils, rinsed
  • 1 onion, finely chopped
  • 2 cloves of garlic crushed
  • 1 stick of celery, finely chopped
  • 1 leek, finely chopped
  • 300g (10.5oz) of sweet potato, chopped
  • some freshly ginger grated
  • 1 tsp of ground cumin
  • 1 splash of tabasco sauce
  • 2 teaspoons of paprika
  • ½ teaspoon of cayenne pepper
  • 500g (17.5oz) of ripe tomatoes, skinned and chopped finely (or use a tinned chopped)
  • 2 litres (8 cups) of vegetable stock
  • 2 tbsp of tomato puree
  • salt and black pepper to season
  • Spray oil
  • finely chopped parsley or coriander
  • optional: yoghurt
  1. Spray a large saucepan over a medium high heat with spray oil.
  2. Add the onion, leek, celery and fry until softened.
  3. Add the lentils, sweet potato, garlic, ginger, cumin, paprika, cayenne and tomato paste and stir to evenly mix.
  4. Add the stock, tomatoes and tabasco sauce.
  5. Bring to a boil, then lower the heat and simmer for about 40mins until lentils are soft.
  6. Season to taste with salt and pepper.
  7. If you prefer a smoother soup, then you can blend it to your liking. I prefer to leave this soup as it is.
  8. Serve topped with a sprinkle of freshly chopped parsley or coriander.
  9. Optional: add a dollop of yoghurt.

    Hi, What measurement is one “serving”? I see it apparently serves four, but I ended up with atleast enough soup for 8! Is the calorie-count per bowl?

  • slimadmin

    One serving is a 1/4 of the entire recipe, so the calorie count is for the same 🙂

  • Dawn

    Just an idea for a variation: It seemed to be begging for Indian spices, so I reduced the stock, and added 2 tsp. each of garam masala and Madras curry powder, plus 1/2 tsp. of turmeric. Quite spicy.
