Make this restaurant-quality creamy roasted tomato basil soup at home. Roasting the tomatoes deepens the flavor, creating a comforting, velvety texture perfect for pairing with grilled cheese.

Ingredients

Scale
  • 3 lbs ripe tomatoes, halved
  • 1 large yellow onion, quartered
  • 4 cloves garlic, unpeeled
  • 3 tablespoons olive oil
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 4 cups vegetable broth
  • 1/2 cup heavy cream
  • 1/2 cup fresh basil leaves, packed
  • 1 teaspoon sugar (optional, to balance acidity)

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius).
  2. Toss the halved tomatoes, onion quarters, and unpeeled garlic cloves with the olive oil, salt, and pepper on a large baking sheet.
  3. Roast for 30 to 35 minutes, until the tomatoes are slightly caramelized and soft.
  4. Remove the garlic skins once cool enough to handle.
  5. Transfer the roasted vegetables and any pan juices to a large pot or Dutch oven.
  6. Add the vegetable broth to the pot. Bring the mixture to a simmer over medium heat.
  7. Remove the pot from the heat. Use an immersion blender to blend the soup until completely smooth and velvety. Alternatively, carefully transfer the soup in batches to a standard blender and blend until smooth, then return it to the pot.
  8. Stir in the heavy cream and the fresh basil leaves. Heat gently for 2 minutes, but do not boil after adding the cream.
  9. Taste the soup and add the optional sugar if the tomatoes are too acidic.
  10. Serve this cozy soup hot, perhaps with grilled cheese soldiers for dipping.

Notes

  • For an even richer flavor, substitute half the vegetable broth with chicken broth.
  • If you do not have fresh basil, you can use 1 tablespoon of dried basil, but add it during the simmering stage before blending.
  • To achieve a truly restaurant-quality texture, press the blended soup through a fine-mesh sieve before adding the cream.
