How to Prepare Roasted Tomato Soup

  1. Tomato Preparation: Start by preheating your oven to 400 degrees F and lining a large baking sheet with parchment paper. Arrange the halved tomatoes and garlic cloves on the sheet. Drizzle them with olive oil and season generously with salt and pepper. Roast for 40-45 minutes until they’re beautifully roasted.
  2. Caramelized Onions: While the tomatoes are in the oven, prepare the caramelized onions. Heat a half tablespoon of olive oil in a large pot over medium heat. Add thinly sliced onions, stirring to coat them in the oil. Cook, stirring occasionally, until they turn golden and caramelize, about 20 minutes.
  3. Blend the Base: After the tomatoes and garlic have roasted and cooled slightly, blend them in a food processor or high-powered blender until smooth. Incorporate the basil leaves and caramelized onions into the blend for an aromatic touch.
  4. Simmer the Soup: Transfer the blended mixture back to the pot. Stir in dried oregano and slowly add water or vegetarian broth to achieve your desired soup consistency. Season with salt and pepper to taste. Let the soup simmer on medium-low heat for about 10 minutes to meld the flavors together.
  5. Serve and Enjoy: Ladle the soup into bowls, garnishing with parmesan cheese if desired. This soup pairs wonderfully with a crispy grilled cheese sandwich for a classic, comforting meal.
