Let’s Get Started
Preheat the oven. Set your oven to 425°F (220°C). Line a large baking sheet with parchment paper.
Prepare the tomatoes. Place the halved tomatoes cut-side up on the baking sheet. Add the garlic cloves and chopped onion. Drizzle with 2 tablespoons of olive oil and season generously with salt and pepper.
Roast for flavor. Roast the vegetables for 30–40 minutes, or until the tomatoes are softened, slightly caramelized, and fragrant.
Sauté for depth. In a large pot, heat the remaining 1 tablespoon of olive oil over medium heat. Add red pepper flakes if using.
Blend the base. Transfer the roasted vegetables to the pot. Pour in the broth and allow it to simmer for 10 minutes to blend the flavors.
Add basil. Stir in the fresh basil leaves.
Blend until smooth. Use an immersion blender directly in the pot or transfer to a blender in batches. Blend until the soup reaches your preferred consistency—smooth or slightly textured.
Adjust and enrich. Taste and adjust seasoning. Add optional sugar if needed. Stir in heavy cream or coconut milk for a richer finish.
Serve warm. Ladle into bowls and top with croutons, a drizzle of olive oil, or extra basil.
