  • 2 lbs (1 kg) Roma tomatoes, halved
  • 1 large onion, finely chopped
  • 4 garlic cloves, minced
  • 3 tablespoons olive oil, divided
  • Salt and pepper, to taste
  • 4 cups (1 liter) chicken or vegetable broth
  • 1/4 cup (6 g) fresh basil leaves, chopped
  • 1 teaspoon sugar (optional)
  • 1/2 teaspoon baking soda (optional, to reduce acidity)
  • 1/2 cup (125 ml) heavy cream (optional, for creaminess)
  • Fresh basil leaves, for garnish

Instructions

  • Roasting the Tomatoes:
    • Preheat the oven to 400°F (200°C).
    • Place the halved Roma tomatoes on a baking sheet, cut side up.
    • Drizzle with 2 tablespoons of olive oil and season with salt and pepper.
    • Roast for 25-30 minutes, or until the tomatoes are soft and slightly caramelized.
  • Cooking the Soup:
    • In a large pot, heat the remaining 1 tablespoon of olive oil over medium heat.
    • Add the finely chopped onion and cook for 5-7 minutes until soft and translucent.
    • Stir in the minced garlic and cook for another minute, until fragrant.
  • Blending the Soup:
    • Once the tomatoes are done roasting, add them to the pot along with any juices from the baking sheet.
    • Pour in the chicken or vegetable broth, and add the chopped basil leaves.
    • Bring the mixture to a simmer and cook for about 10 minutes to blend the flavors.
  • Optional Additions:
    • If you prefer a slightly sweeter soup, add 1 teaspoon of sugar.
    • To reduce the acidity, stir in ½ teaspoon of baking soda.
    • For a creamier texture, stir in the heavy cream and cook for an additional 5 minutes.
  • Blending:
    • Using an immersion blender (or carefully transferring the soup to a blender in batches), blend until smooth.
    • Adjust seasoning with salt and pepper to taste.
  • Serving:
    • Ladle the soup into bowls and garnish with fresh basil leaves.
    • Serve with crusty bread or a grilled cheese sandwich for the ultimate comfort meal.
