Creating a bowl of Tomato Basil Soup is straightforward. Follow these steps for delicious results:

1. Sauté Onion and Garlic: In a large pot over medium heat, add olive oil. Once heated, sauté the chopped onion until it becomes translucent, about 5 minutes. Add the minced garlic and cook for an additional 1-2 minutes until fragrant.
2. Add Tomatoes: Stir in the chopped fresh tomatoes (or canned tomatoes) and sugar, if using. Let it simmer for about 10 minutes, stirring occasionally.
3. Add Broth: Pour in the vegetable broth. Bring the mixture to a boil, then reduce heat and let it simmer for another 10 minutes.
4. Blend the Soup: Remove the pot from heat. Using an immersion blender, carefully blend the soup until smooth. Alternatively, transfer the mixture in batches to a countertop blender.
5. Stir in Basil: Return the blended soup to low heat. Add the fresh basil leaves and let it simmer for another 5 minutes, allowing the flavors to meld.
6. Optional Cream Addition: If you prefer a creamy texture, stir in the heavy cream at this stage. Warm through but do not boil.
7. Season: Taste the soup and season with salt and pepper as desired.
8. Serve: Ladle the soup into bowls and garnish with grated Parmesan cheese if desired.

Following these steps will ensure a perfect Tomato Basil Soup that is both comforting and full of flavor!
