Servings 4


  • 1 kg tomatoes halved or quartered if plump
  • 2 carrots peeled and roughly chopped
  • 2 large red onions roughly chopped
  • 2 plump garlic cloves
  • 4 tbsp olive oil
  • salt and pepper
  • 750 ml vegetable stock (or up to 1 litre if you prefer a watery texture)
  • 2 tbsp Sacla' free from tomato pesto optional
  • pinch of sugar
  • fresh basil leaves to garnish

For the pesto croutons

  • 3-4 slices bread
  • 1/2 jar Sacla' classic basil pesto
  • flaked sea salt


  • Preheat the oven to 180°C (fan)/200°C/gas mark 6.
  • Tip the tomatoes, carrots, red onions and garlic into a roasting tray. Toss with the oil and season with salt and pepper. Roast for 45 minutes until soft and golden.
  • While they're roasting, whip up the croutons. Tear the bread into rough bite-sized pieces, spread them out onto a baking tray and mix thoroughly with the pesto and oil and a generous pinch of salt.
  • Put them in the oven, on the shelf above the veg, and cook for 8-10 minutes, stirring once, until crisp and toasty (timings may vary depending on what type of bread you use). Remove from the oven and set aside. 
  • When the vegetables are soft and golden, scrape them all into a large saucepan along with any lovely caramelised sticky bits from the bottom of the roasting tray. 
  • Add the hot stock and heat gently over a medium heat. Simmer for 15 minutes then, using a stick blender, purée the soup, adding a little extra stock if needed until you get the consistency you like. 
  • Stir through the tomato pesto and season to taste with salt, pepper, and a pinch of sugar.
  • Stir well then serve with a handful of crunchy pesto croutons and a few basil leaves.
