Lentil and Tomato Soup with Pasta

This is the soup you make when you want something that actually fills you up rather than just warming your hands. Red lentils and tiny pasta cook right in the tomato broth, thickening it into something that sits between a soup and a stew. At 33p a portion it is one of the cheapest proper meals you can make. The lentils provide protein and the pasta provides carbohydrates, so it is genuinely balanced rather than just cheap. The pasta releases starch as it cooks which gives the soup a silky, slightly creamy texture without any actual cream. Stir it often once the pasta goes in or it will stick to the bottom.

Total cost: £1.30 (£0.33 per portion) – Serves 4 people. Prep: 5 mins | Cook: 25 mins

Lentil and Tomato Soup with Pasta

A hearty Italian-style soup that eats like a meal. Red lentils and tiny pasta cook in a tomato broth for a thick, filling bowl that costs under 35p per portion.
Prep Time 5 minutes
Cook Time 25 minutes
Servings: 4 people
Course: Soup
Cuisine: Italian

Ingredients
  

  • 100g red lentils
  • 1 tin (400g) chopped tomatoes
  • 80g small pasta (ditalini, orzo or broken spaghetti)
  • 1 onion, diced
  • 2 cloves garlic, minced
  • 1 tsp dried oregano
  • 1 tsp dried basil
  • 750ml vegetable stock
  • 1 tbsp olive oil
  • salt and pepper
  • parmesan or hard cheese to serve (optional)

Method
 

  1. Heat the olive oil in a large saucepan. Add the onion and cook for 5 minutes until soft.
  2. Add the garlic, oregano and basil. Cook for 1 minute until fragrant.
  3. Pour in the chopped tomatoes, red lentils and stock. Stir well and bring to the boil.
  4. Reduce the heat and simmer for 15 minutes until the lentils are starting to break down.
  5. Add the small pasta and cook for another 8-10 minutes, stirring frequently, until the pasta is tender and the soup has thickened.
  6. Season with salt and pepper. Serve in warm bowls with grated cheese if you have it.

Tips and Variations

Stir frequently once the pasta is added – it loves to stick. The soup thickens as it sits so add water when reheating. Any small pasta works – break spaghetti into small pieces if that is what you have. A dollop of pesto stirred in at the end is an excellent upgrade. This freezes well but the pasta absorbs liquid as it thaws, so add extra stock or water.
