1/4 cup fresh basil leaves, chopped, plus extra for garnish
1 teaspoon sugar (optional, to balance acidity)
1 tablespoon fresh orange juice (optional, for brightness)
Instructions
Preheat your oven to 400°F (200°C).
Pour the canned tomatoes (with their juice) onto a baking sheet. Add the chopped onion and unpeeled garlic cloves to the sheet. Drizzle everything with olive oil, salt, and pepper.
Roast for 25 to 30 minutes, until the tomatoes are slightly blistered and the onions are soft.
Remove the garlic skins. Place the roasted tomatoes, onions, and any pan juices into a large pot or Dutch oven. Add the broth.
Bring the mixture to a simmer over medium heat. Cook for 10 minutes to allow flavors to combine.
Carefully transfer the soup mixture to a blender (or use an immersion blender directly in the pot). Blend until completely smooth and velvety. Work in batches if using a standard blender, ensuring the lid is vented to allow steam to escape.
Return the smooth soup to the pot over low heat. Stir in the heavy cream, butter, sugar (if using), and orange juice (if using). Heat gently until the butter melts and the soup is warmed through. Do not boil after adding cream.
Stir in the chopped fresh basil during the last minute of heating.
Taste and adjust salt and pepper as needed. Serve hot, garnished with extra fresh basil.
Notes
For the smoothest texture, strain the blended soup through a fine-mesh sieve before adding the cream.
This bisque pairs perfectly with a classic grilled cheese sandwich for dipping.
If you prefer a richer flavor, substitute half the broth with chicken stock.
