Instructions

1. Roast the Tomatoes:
   • Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper.
   • Arrange the halved tomatoes and garlic cloves on the baking sheet. Drizzle with olive oil and season generously with salt and pepper.
   • Roast for 40-45 minutes until the tomatoes are soft and slightly caramelized.
2. Caramelize the Onions:
   • While the tomatoes are roasting, heat olive oil in a large pot over medium heat. Add the thinly sliced onions, stirring to coat them evenly in oil.
   • Cook the onions, stirring occasionally, until they are golden and fully caramelized. This process takes about 20 minutes.
3. Blend the Soup Base:
   • Once the roasted tomatoes and garlic have cooled slightly, transfer them to a food processor or blender. Blend until smooth.
   • Add the caramelized onions and basil leaves, then blend again until fully combined. Alternatively, you can use an immersion blender directly in the pot.
4. Simmer the Soup:
   • Pour the blended mixture back into the pot. Stir in oregano and vegetable broth or water. Adjust the liquid to reach your preferred consistency.
   • Season with salt and pepper to taste. Add any optional ingredients, such as coconut milk, cream, or Parmesan cheese, to enhance the flavor.
   • Simmer over medium-low heat for 10 minutes to allow the flavors to meld.
5. Serve:
   • Ladle the soup into bowls, garnish with Parmesan cheese if desired, and pair with warm grilled cheese for the perfect comforting meal. Serves 4.
