Equipment

  • 1 large baking sheet
  • 1 kitchen scale
  • 1 measuring spoons
  • 1 Lodge Dutch oven
  • 1 Rubber spatula
  • 1 Sharp knife

Ingredients

  • 2-3 tablespoon olive oil
  • 4 medium tomatoes (around 1 lbs/450 grams) (cut in halves)
  • 2 red romano peppers or large capsicum
  • 4 cloves garlic
  • 4-5 sprigs fresh thyme
  • 1 medium onion (cut in chunky dices)
  • 2 bay leaves
  • 1 teaspoon salt
  • ½ teaspoon freshly ground black pepper
  • ½ teaspoon paprika
  • 4 cups vegetable stock or water

Instructions

  • Preheat the oven to 220° C (430° F).
  • Place the tomatoes, red peppers, onion, garlic, and thyme on a baking tray, and drizzle 2 tablespoons of olive oil on top.
  • Roast the vegetables in the preheated oven for 20 to 25 minutes or until the skin of the peppers is charred.
  • Remove the tray from the oven and set it aside for 10 minutes until the vegetables have cooled enough.
  • When the veggies are cooled down enough for you to handle them, peel the tomatoes and garlic, and peel and deseed the peppers.
  • Place them in a heavy-based pan along with the onions, salt, freshly ground black pepper, paprika, bay leaves, and vegetable stock or water. 
  • Give them a good stir and gently simmer for 20 to 25 minutes on low to medium heat with a lid on.
  • Remove the bay leaves, transfer the soup to a food processor or with a hand-held blender, and blitz until smooth. Add extra stock if too thick or boil the soup further if too thin.
  • Garnish with grated parmesan, sour cream, or a drizzle of olive oil.

Notes

  • Red Pepper and Tomato Soup taste better when made at the end of summer when ripe and sweet tomatoes and peppers are in season.
  • You can make this soup with tinned tomatoes. Make sure you add a pinch of sugar to balance the acidity!
  • Roasting the vegetables gives this soup a rich&deep flavor and is strongly advised! However, if you are short of time, you can skip this step. You will still have a delicious soup but will taste lighter!
  • Roast your vegetables in a big roasting pan or baking sheet to avoid overcrowding them. This way, you will have single-layered vegetables, so they will nicely roast. 
  • Add extra stock if your soup is too thick or boil the soup further if too thin.
  • This delicious soup will stay fresh for up to 5 days in the fridge to up to 5 months in the freezer.
