Make this creamy roasted tomato basil soup for a comforting, rich meal. Roasting the tomatoes deepens the flavor, resulting in a velvety texture that rivals your favorite restaurant. This easy recipe fits a busy schedule.

Ingredients

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

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit.
  2. Toss the halved tomatoes, onion quarters, and unpeeled garlic cloves with 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. Add the vegetable broth.
  6. Bring the mixture to a simmer over medium heat. Cook for 10 minutes to allow flavors to meld.
  7. Remove the pot from the heat. Stir in the fresh basil leaves and the sugar, if using.
  8. 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, returning it to the pot.
  9. Stir in the heavy cream until fully incorporated. Heat gently, but do not boil after adding the cream.
  10. Taste and adjust salt and pepper as needed. Serve hot, perhaps with grilled cheese for the ultimate pairing.

Notes

  • For a thicker, velvety texture without dairy, substitute the heavy cream with 1/2 cup of soaked and blended raw cashews.
  • If you do not have fresh basil, you can use 1 tablespoon of dried basil, but add it during the simmering step, not at the end.
  • This soup freezes well. Cool completely before transferring to airtight containers.
