Ingredients

Scale
  • 2 lbs ripe tomatoes, halved
  • 1 large yellow onion, quartered
  • 4 cloves garlic, unpeeled
  • 2 tablespoons olive oil
  • 1 teaspoon dried oregano
  • 1/2 teaspoon salt
  • 1/4 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 teaspoon sugar
  • 1/4 teaspoon baking soda
  • 1/2 cup heavy cream

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit. Toss the halved tomatoes, onion quarters, and unpeeled garlic cloves with olive oil, oregano, salt, and pepper on a baking sheet.
  2. Roast for 25 to 30 minutes, until the tomatoes are slightly softened and beginning to caramelize.
  3. Remove the garlic skins once cool enough to handle. Place the roasted tomatoes, onions, and garlic into a large pot or Dutch oven.
  4. Add the vegetable broth and the can of fire-roasted diced tomatoes. Bring the mixture to a simmer over medium heat. Cook for 10 minutes to let the flavors combine.
  5. Remove the pot from the heat. Stir in the fresh basil, sugar, and baking soda. The baking soda helps neutralize acidity for a smoother taste.
  6. Carefully transfer the soup mixture to a blender in batches, or use an immersion blender directly in the pot. Blend until completely smooth and silky.
  7. Return the pureed soup to the pot over low heat. Stir in the heavy cream until fully incorporated and the bisque is heated through. Do not boil after adding the cream.
  8. Serve your velvety tomato bisque immediately, perhaps with grilled cheese for dipping.

Notes

  • For an even richer flavor, substitute half the vegetable broth with chicken broth.
  • If you prefer a less sweet soup, reduce the added sugar to 1/2 teaspoon.
  • This recipe makes a fantastic base for a vegetarian comfort meal.
