Step 1

Heat olive oil in a pot over low heat and cook onion until soft and translucent. Add garlic and cook until fragrant, about 1 minute. Increase heat to medium, add all tomatoes, and cook until they start to break down, about 5 minutes. Stir occasionally. Add vegetable broth, bay leaves, and 1 sprig of basil. Bring to a boil, reduce heat, and simmer until tomatoes have broken down and soup starts to thicken, about 30 minutes.

Step 2

Remove soup from heat and cool slightly. Remove bay leaves and basil.

Step 3

Puree tomato soup with an immersion blender until smooth. Reheat soup before serving and garnish with basil leaves.
