Sweet potato and bean soup

Autumn is definitely here.  Crisp mornings with air that tingles the end of your nose, leaves turning an array of colours before they drop to the ground in a pile ready to be jump in. Or, more sadly, stormy grey days with enough rain to send you into the back of the cupboard to hunt out the wellies. But whatever the weather, autumn is also time for thick, soul-soothing soup.

Now you many say “But Karen, you say soup is for any time of the year”, and you would be right, I do. But there are particular autumn soups that truly warm the cockles of my heart, reminding me of hot summers days – the orange ones, made with my favourite veggies pumpkins, sweet potatoes and carrots.

  • all in season
  • all dazzling orange
  • all packed with wonderful betacartene and other phytonutrients that support the immune system.
  • And all ‘souper’ tasty!

Soup is a great way of packing more veggies and fibre into your daily diet. We have a portion most days of the week. Home-made soup is the best as you control what goes in it, especially if you’re following a special diet or don’t eat certain things due to food intolerances or health challenges. Soup is a perfect way of eating plant-based, whole-food and gluten free if that’s what you need.

If you read the label of a shop-bought soup it suddenly doesn’t seem quite as healthy as you would like it to be. The salt content is often way off the scale for a start, but refined oils and sugar have a habit of being sneaked in as well as a range of additives and other chemicals that no-one really knows what they are. Making soup at home needn’t be laborious or expensive, and if you make a big batch, you can freeze portions to take to work or grab out of the freezer when you’re short on time (just remember to label them otherwise it’s lucky dip!).

This soup is so easy to make and is packed full of fibre from the beans and the sweet potato that your microbiome will enjoy it just as much as you. I’ve used cannellini beans, but butter beans or any white bean will do.

So batten down the hatches and grab a big pan and whip up a batch of this delicious soup. Then close your eyes and think of warm summer days rather than the rain lashing at the window! And don’t forget to let me know how you get on. Enjoy!
