Ingredients

Scale
  • 3 lbs ripe tomatoes, halved
  • 1 large yellow onion, quartered
  • 4 cloves garlic, unpeeled
  • 3 tablespoons olive oil
  • 1 teaspoon dried oregano
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 4 cups vegetable broth
  • 1 (14.5 ounce) can fire-roasted diced tomatoes, undrained
  • 1/2 cup fresh basil leaves, packed
  • 1/4 cup heavy cream
  • 1 teaspoon baking soda (optional, for smoothness)

Instructions

  1. Preheat your oven to 400°F (200°C).
  2. Toss the halved tomatoes, onion quarters, and unpeeled garlic cloves with olive oil, oregano, salt, and pepper on a large baking sheet.
  3. Roast for 30 to 35 minutes, until the tomatoes are slightly charred and softened.
  4. Remove the garlic skins once cool enough to handle.
  5. Transfer the roasted vegetables (including any pan juices) to a large pot or Dutch oven. Add the vegetable broth and the canned fire-roasted diced tomatoes.
  6. Bring the mixture to a simmer over medium heat. Cook for 10 minutes to allow the flavors to meld.
  7. Remove the pot from the heat. Stir in the fresh basil leaves.
  8. Carefully transfer the soup mixture in batches to a high-powered blender. Blend until completely smooth and velvety. Alternatively, use an immersion blender directly in the pot until silky smooth.
  9. Return the pureed soup to the pot over low heat. Stir in the heavy cream. If you want an extra silky texture, whisk in the baking soda now; it will foam briefly.
  10. Heat through gently without boiling. Taste and adjust salt and pepper as needed before serving hot with grilled cheese dippers.

Notes

  • For the best flavor, use ripe, in-season tomatoes.
  • If you do not have fresh basil, substitute with 1 teaspoon of dried basil, added during the simmering step.
  • To make this a complete meal, serve with homemade grilled cheese sandwiches for dipping.
