Velvety sweet potatoes and salty bacon combine to make this immensely flavourful roast sweet potato soup.

The key to this roasted sweet potato soup is cooking the sweet potato in two parts. The roasting stage concentrates the flavour, slightly caramelising the outside of the vegetable and bringing out its sweetness. Meanwhile, the bacon is cooked in the same pan as the soup, so none of that fried saltiness is lost. We like a thick soup that still has a bit of chunkiness to it, so we've only blended half the soup here. However, if you prefer it fully smooth blend the whole thing. Or if you like chunks, go natural. When sweet potatoes are in season, from October to March, they are cheap and plentiful and this is a great budget meal - one of our best cheap family meals.


  • 3 medium sweet potatoes, peeled and cut into chunks
  • 3 tbsp olive oil
  • 8 rashers bacon, diced
  • 2 cloves garlic
  • 2 tsp paprika
  • 1 onion, finely chopped
  • 1 litre chicken or vegetable stock
  • Sea salt and black pepper




  1. Pre-heat the oven to 200ºC/400ºC/Gas 6.
  2. Toss the sweet potato with 2 tbsp olive oil, season and roast in the oven for 15 mins or until golden brown and soft.
  3. Meanwhile, heat the remaining oil in a large saucepan. Add the bacon and cook for 5 mins, stirring, until brown and crispy.
  4. Add the garlic and paprika and cook for 30 secs. Stir in the onion and cook gently for 10 mins, until softened but not browned.
  5. Pour in the stock and bring to the boil. Reduce to a simmer and gently add the roasted sweet potatoes, cook for 5 mins.
  6. Remove half of the onion and potato mixture with a slotted spoon. Then carefully blend the remaining soup, until smooth. Return the onion and potato mixture to the pan.
  7. Squeeze in the lemon juice and season to taste.

Top tips for making roast sweet potato soup

Smoked or unsmoked bacon is really a matter of personal choice, but smoked does go especially well in this recipe. The extra depth of flavour really complements the earthiness of the sweet potato. 

Swirl a little cream or Greek yoghurt in the top of the soup and toss over a few croutons to fancy this soup up a little.
