  • 2 cups diced butternut squash 1/2 inch dice
  • 3 pointed red peppers roughly chopped
  • 1/4 teaspoon chilli flakes
  • 2 tablespoons olive oil divided
  • 1 onion finely diced
  • 2 garlic cloves crushed
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon ground cumin
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon dried thyme
  • 1/2 cup red lentils
  • 3 cups chicken or vegetable stock (750ml)
  • salt and pepper to taste
  • Greek yoghurt for garnish
  • fresh thyme leaves for garnish


  • Preheat oven to 200°C/400°F. Line a baking sheet with parchment paper.
  • Add the diced butternut squash and the chopped red peppers to the baking sheet. Sprinkle with the chilli flakes, drizzle with 1 tablespoon of the oil and add a good pinch of salt and pepper. Toss with your hands to coat. Roast in the preheated oven for 25-30 minutes until everything is tender and a little charred at the edges.
  • Whilst the vegetables are roasting, heat the remaining tablespoon of olive oil in a large saucepan over medium high heat. Once hot, add in the onion and saute for 5 minutes or until softened.
  • Add the garlic and spices and continue to cook, stirring, for 30 seconds.
  • Add the red lentils to the pot and give them a good stir to coat in the onions and spices. Next, pour in the stock and bring to the boil.
  • Reduce the heat to a simmer and add the roasted vegetables. Continue to simmer for 15 minutes until the lentils are soft.
  • Carefully transfer everything into a blender and blend until smooth. Take care to cover the top of the blender with a tea towel to avoid any splashes and start blending slowly, gradually increasing the speed until smooth.
  • Season to taste and serve topped with a little yoghurt and thyme leaves, if liked. See notes section below for suggested instructions on how to make some tasty little cheesy toasts for dipping.


  • Use your favourite variety of squash - red kuri, acorn and kabocha all work well. Some varieties of squash cook a little quicker, so start checking at 20 minutes. 
  • If you can't get hold of red pointed peppers, use red bell peppers instead.
  • If you don't have an upright blender, you can use a hand-held stick blender.
  • This recipe makes about 1.2 litres or 5 cups of soup, which equates to about 3 full servings or 4 smaller ones. 
  • Delicious served with some smoky cheesy toasts - lightly toast some slices of baguette and top with grated cheddar cheese, a sprinkle of smoked paprika and a few thyme leaves. Place under the grill/broiler for a minute or two until melted and golden.
