  • 650 g sweet potatoes (3 regular sized potatoes)
  • 3 roasted red peppers, skin removed (from a jar)
  • 4 garlic cloves
  • 1 onon
  • 1 teaspoon garam masala
  • 200 ml coconut milk
  • 500 ml vegetable stock (or water + stock cube)
  • ½ teaspoon salt


  • 1 teaspoon sriracha or chili powder (if you want the soup to be spicy)


  • Preheat your oven to 200°C / 180°C fan oven / 395°F.
  • Dice the sweet potatoes and place them on a baking tray. Spray some one calorie cooking spray over them, and add a sprinkle of salt. Bake until they are soft enough to push a fork through them, about 20 minutes.
  • Meanwhile, in a large pot, heat some one calorie cooking spray and add finely diced onion and garlic. Saute until the onion is soft and translucent (5 minutes).
  • Place 3 jarred roasted peppers, and pat them dry with a paper towel. Dice them roughly, and add them to the pot with the onions and garam masala. Leave it to saute until the peppers have warmed up, about 2 minutes.
  • Then, add coconut milk, vegetable stock and salt. Bring it to a boil, and leave it to cook for a few minutes.
  • Add the roasted sweet potatoes, and let the soup simmer for about 10 minutes.
  • Blend the soup smooth using an immersion blender or a regular blender.
  • Finally, add seasoning to taste and serve.


Can you freeze sweet potato and red pepper soup? Absolutely, this soup is perfect for freezing for up to 3 months. Allow the soup to cool completely before transfering it to airtight containers and placing it in the freezer.
Can you roast your own peppers? For simplicity, I use ready roasted red peppers from a jar in this recipe. To roast your own peppers, you can try this recipe. Keep in mind that this will add 30 minutes to the total cooking time.
How to store leftovers – Allow leftover soup to cool down completely, then store it in airtight containers in the fridge for up to 5 days.

Tips and tricks

  • Pat dry the roasted peppers to remove most of the oil. This doesn’t affect the flavour or texture, but leaves the dish with fewer calories.
  • Don’t rush the cooking time. This dish needs time for all the flavours to merge, or it will come out tasting like pure coconut milk.
  • Add seasoning to taste at the end. Add sriracha or chili powder if you want some spice, or some salt if you would prefer more. You could also try curry powder, smoked paprika or Moroccan seasoning. Your preferences might be different to mine!
  • If you choose to roast your own peppers, make sure to remove the skin and seeds, or your soup might have a strange texture with chewy bits.
