Ingredients
Method
Preheat oven to 375°F (190°C).
Prepare the vegetables: Cut the tomatoes and onion into similar-sized pieces. Trim the top of the garlic head, drizzle with olive oil, wrap in foil, and place alongside the tomatoes and onion on a sheet pan.
Roast the vegetables: Roast in the preheated oven for 40-45 minutes until tomatoes and onions are soft and slightly caramelized, and the garlic is tender.
Prepare the soup base: In a large pot, warm 3 tablespoons of olive oil over medium heat. Add 1 tablespoon of tomato paste and cook for 1-3 minutes, stirring occasionally until the paste darkens.
Add the roasted vegetables: Once the vegetables are done, transfer them to the pot along with all the juices from the sheet pan. Add the chicken or vegetable broth.
Blend the soup: Use an immersion blender or transfer the mixture to a blender. Blend until smooth and silky.
Simmer for depth: Add the Parmigiano Reggiano rind (if using), and simmer for 10-15 minutes. Remove the rind before serving.
Finish the soup: Taste and adjust seasoning with salt and pepper. Optionally, stir in cream for extra richness.
Serve: Ladle the soup into bowls and garnish with fresh basil leaves and grated Parmesan if desired.
Notes
- You can substitute Parmigiano Reggiano rind with a vegetarian hard cheese rind for a meat-free version.
- Use fire-roasted canned tomatoes if fresh tomatoes aren't available.
- If the soup tastes too acidic, add a pinch of sugar or a small knob of butter to balance the flavors.
