Ingredients

  • 2 tablespoon olive oil
  • 1 carrot small, diced (50g)
  • 2 celery stalks diced (80g) ¾ cup chopped
  • 1 small onion diced (70g)
  • 2 garlic cloves minced
  • 14 oz canned chopped tomatoes 1 tin of 400g
  • 2 cups cherry tomatoes 300g
  • 5 cups chicken broth 1.2 litre
  • ¼ cup fresh basil leaves chopped (12g)
  • Salt + pepper to taste

Optional Basil Oil

  • ¼ cup fresh basil leaves chopped (12g)
  • ¼ cup olive oil 60ml
  • pinch of salt

Instructions

  • Heat the oil in a large pan over a medium heat. Add the chopped carrot, celery and onion and sauté on a medium heat for 3 - 4 mins until soft. Add the garlic for 1 more minute until fragrant.
  • Add fresh and tinned tomatoes, chicken broth, salt and pepper. Stir and bring to the boil, then reduce to a simmer for 10 - 15 minutes with the lid on slightly ajar.
  • Stir though the chopped basil.
  • Place in a blender and blend until smooth. Option to use a hand blender, making sure the soup doesn’t splatter and burn you. Adjust seasoning to taste.

Optional Basil Oil

  • Add basil, oil and pinch of salt to a small blender. I used an electric spice grinder. Blitz until smooth and drizzle over the soup.
