Follow these simple steps to make Gordon Ramsay Roasted Tomato Soup:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C).
2. Prepare the Tomatoes: Wash the tomatoes and cut them in half. Place them cut side up on a baking sheet.
3. Add Olive Oil & Seasoning: Drizzle the tomatoes with olive oil. Sprinkle with salt, pepper, and sugar, ensuring even coverage.
4. Roast the Tomatoes: Roast the tomatoes in the preheated oven for about 25-30 minutes until they are caramelized and tender.
5. Sauté the Onion and Garlic: In a large pot over medium heat, add a tablespoon of olive oil. Sauté the diced onion until translucent, about 5 minutes. Add the minced garlic and cook for an additional minute, being careful not to burn it.
6. Combine Ingredients: Once the tomatoes are done roasting, add them, including any juices, to the pot with the onions and garlic.
7. Add Broth and Basil: Pour in the vegetable broth and add the fresh basil leaves. Stir to combine.
8. Simmer: Bring the mixture to a boil, then reduce the heat and let it simmer for about 10 minutes, allowing the flavors to meld.
9. Blend the Soup: Use an immersion blender to puree the soup until smooth. Alternatively, transfer the mixture to a blender in batches, then return it to the pot.
10. Finish with Cream: If desired, stir in the heavy cream for added richness. Adjust seasoning with salt and pepper.
11. Serve Hot: Ladle the soup into bowls and garnish with fresh basil leaves for a beautiful presentation.
