Description

This Roasted Tomato Basil Soup features ripe tomatoes, garlic, and onions oven-roasted to deepen their flavors, blended with fresh basil and vegetable broth to create a smooth, comforting soup. It’s a perfect vegetarian and gluten-free dish that’s easy to prepare and customizable with optional creaminess or spice additions.


Ingredients

Scale

Vegetables

  • 2 ½ pounds ripe tomatoes, halved
  • 1 medium yellow onion, quartered
  • 6 cloves garlic, peeled

Other Ingredients

  • 2 tablespoons olive oil
  • Salt and black pepper to taste
  • 1 cup fresh basil leaves, packed
  • 2 cups vegetable broth
  • 1 teaspoon sugar (optional)
  • ½ cup heavy cream or coconut milk (optional for creaminess)


Instructions

  1. Preheat Oven and Prepare Vegetables: Preheat your oven to 425°F (220°C). Arrange the halved tomatoes, quartered onions, and peeled garlic cloves on a baking sheet. Drizzle them evenly with olive oil and season with salt and black pepper to enhance their natural flavors.
  2. Roast the Vegetables: Place the baking sheet in the oven and roast the vegetables for 35 to 40 minutes. Roast them until the tomatoes are soft, juicy, and slightly charred, adding a rich depth of flavor to the soup. Once done, remove from the oven and allow them to cool slightly.
  3. Blend the Soup Base: Transfer the roasted vegetables along with their juices to a blender or food processor. Add the fresh basil leaves and blend everything together until smooth, creating a vibrant and fragrant soup base.
  4. Simmer the Soup: Pour the blended mixture into a large pot and set over medium heat. Stir in the vegetable broth and bring to a gentle simmer. Taste the soup and adjust the seasoning; add sugar if the soup tastes too acidic.
  5. Add Creaminess and Final Simmer: For a creamy texture, stir in heavy cream or coconut milk at this stage. Let the soup simmer for an additional 5 to 10 minutes to allow all the flavors to meld beautifully before serving warm.

Notes

  • For a chunkier texture, blend only half of the roasted mixture and mix it with the remaining unblended vegetables.
  • Use canned tomatoes if fresh tomatoes are out of season for convenience and consistent flavor.
  • Add a pinch of red pepper flakes during simmering for a spicy kick.
