This recipe delivers a rich, velvety tomato bisque using roasted tomatoes and garlic for deep flavor. It is a comforting homemade soup, perfect for pairing with grilled cheese sandwiches.

Ingredients

Scale
  • 3 lbs ripe tomatoes, halved
  • 4 whole garlic cloves, unpeeled
  • 2 tablespoons olive oil
  • 1 teaspoon salt, divided
  • 1/2 teaspoon black pepper, divided
  • 1 medium yellow onion, chopped
  • 4 cups vegetable broth
  • 1/2 cup fresh basil leaves, packed
  • 1/2 cup heavy cream
  • 1 teaspoon sugar

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit. Toss the halved tomatoes and whole garlic cloves with olive oil, 1/2 teaspoon salt, and 1/4 teaspoon pepper on a baking sheet.
  2. Roast for 25 to 30 minutes, until the tomatoes are slightly softened and beginning to caramelize. Squeeze the roasted garlic from its skin once cool enough to handle.
  3. In a large pot, heat a small amount of oil over medium heat. Add the chopped onion and cook until soft, about 5 minutes.
  4. Add the roasted tomatoes, roasted garlic, vegetable broth, sugar, remaining 1/2 teaspoon salt, and remaining 1/4 teaspoon pepper to the pot. Bring the mixture to a simmer.
  5. Reduce the heat to low, cover, and cook for 10 minutes to let the flavors combine.
  6. Carefully transfer the soup mixture to a blender, or use an immersion blender directly in the pot. Blend until completely smooth and velvety. For the silkiest texture, strain the soup through a fine-mesh sieve.
  7. Return the smooth soup to the pot over low heat. Stir in the fresh basil leaves and heavy cream. Heat through gently, but do not boil.
  8. Serve your creamy tomato bisque hot, perhaps with a classic grilled cheese pairing.

Notes

  • For an even richer flavor, roast the tomatoes for 10 minutes longer until they show more browning.
  • If you prefer a less sweet soup, reduce the sugar to 1/2 teaspoon or omit it.
  • This soup freezes well before adding the heavy cream. Thaw and reheat gently before adding the cream.
