Creamy vegan roasted red pepper and tomato soup made with oven-roasted bell peppers, Roma tomatoes, garlic, fresh basil, and vegan heavy cream. Roasting the vegetables gives this easy soup a rich and deep flavor. The red wine vinegar balances their natural sweetness of the tomatoes and peppers.
Prepare the vegetables: Preheat the oven to 425°F. Place the red bell peppers, tomatoes, and onion on a large baking sheet. Drizzle with 1 and 1/2 tablespoons of olive oil, season with salt and pepper, and toss to evenly coat the vegetables (I do this with my hands).
Prepare the garlic: Slice the top of the garlic head, exposing the cloves. Drizzle the remaining 1/2 tablespoon of olive oil on top, loosely wrap the bulb in foil, and place it on the sheet pan with the other vegetables.
Oven-roast: Place the sheet pan on the oven’s middle rack and roast for 35 to 45 minutes, stirring once halfway through. Roast until the peppers and tomatoes are soft and just starting to char around their edges.
Build the Soup: Heat a large pot over medium heat. Add 1 teaspoon of olive oil and tomato paste. Stir frequently for 1 to 2 minutes or until the color starts to darken. Add the roasted peppers, tomatoes, and onion to the pot. Squeeze in the roasted garlic cloves. Add 2 cups of vegetable broth, oregano, and red pepper flakes. Simmer for 10 to 15 minutes, allowing the flavors to marry.
Blend: Tear the basil leaves and add them to the soup. Using an immersion blender, blend all the ingredients. Reduce the heat to a simmer. Add the vegan cream and 1 teaspoon of red wine vinegar. If you want a thinner soup, you can add more vegetable broth at this step.
Taste and serve: Taste the soup and adjust to your preferences by adding additional salt, pepper, or vinegar. Serve in a bowl with a decorative drizzle of cream or olive oil and torn basil leaves.
Notes
You can use a blender in place of an immersion blender. First, reduce the heat to low and allow the temperature to drop. Then gently transfer the ingredients to a blender. Use caution, as the ingredients are hot and can splatter.
