Ingredients

  • 30 ml (2 tablespoon) olive oil
  • 4 red peppers, halved and deseeded
  • 1 red onion, roughly chopped
  • 6 cloves garlic, peeled and whole
  • Leaves from 4 sprigs thyme
  • Leaves from 2 sprigs rosemary, chopped
  • 15 g (1 ¼ tablespoon) light brown sugar, optional
  • Juice of ½ lemon
  • 1 vegetable stock cube dissolved in 500 ml (1 cup) boiling water
  • ½ bunch basil

For Serving (Optional)

  • Fresh mozzarella, torn into quarters
  • 50 ml ( cups) olive oil with chopped basil leaves stirred through

Instructions

  • Preheat your oven to 190-200ºC.
  • Place the halved and deseeded red peppers cut side up on a roasting tray. Sprinkle with the chopped rosemary and thyme leaves. Drizzle with olive oil and toss with the roughly chopped onion and peeled garlic cloves. If using, sprinkle the light brown sugar over the top.
  • Roast in the preheated oven for about 15 minutes, until the peppers are soft and charred on the edges.
  • Once roasted, transfer the peppers, onions, and garlic to a medium saucepan. Add the 500 ml vegetable stock.
  • Using an immersion blender, blend the soup until thick and smooth. Add the basil leaves and blend again until the basil is fully incorporated. Taste and adjust seasoning as necessary, keeping in mind that the stock cube is already salty.
  • Stir in the lemon juice to brighten the flavors.

Notes

  • Roasting Tray: Use a large enough tray so the peppers are not overcrowded; this ensures they roast properly and do not steam.
  • Customization: For a spicy kick, add some chilli flakes before roasting.
  • Serving Suggestion: Garnish with torn fresh mozzarella and a drizzle of olive oil infused with chopped basil for added richness and flavour.
