Make this ultra-creamy roasted tomato basil bisque from scratch for a velvety, satisfying comfort food experience. Roasting the tomatoes and garlic adds deep flavor, making this homemade soup superior to canned options. It is ready quickly, perfect for cozy dinners.

Ingredients

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

Instructions

  1. Preheat your oven to 400°F (200°C).
  2. Toss the halved tomatoes, onion quarters, and unpeeled garlic cloves with olive oil, salt, and pepper on a baking sheet.
  3. Roast for 25 to 30 minutes, until the tomatoes are slightly charred and softened.
  4. Remove the garlic from its skin 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.
  6. Bring the mixture to a simmer over medium heat and cook for 10 minutes to allow flavors to meld.
  7. Remove the pot from the heat. Stir in the fresh basil leaves.
  8. Use an immersion blender to blend the soup until it is completely silky smooth. Alternatively, carefully transfer the soup in batches to a standard blender and blend until smooth, then return it to the pot.
  9. Stir in the heavy cream and the optional sugar. Heat gently until warmed through; do not boil after adding cream.
  10. Taste and adjust salt and pepper as needed before serving.

Notes

  • For the ultimate pairing, serve this velvety tomato soup with a classic grilled cheese sandwich for dipping.
  • If you prefer a smokier flavor, use fire-roasted tomatoes instead of fresh ones.
  • To achieve an extra-smooth texture, strain the finished bisque through a fine-mesh sieve before adding the cream.
