History and Background
Tomato soup has been a beloved comfort food since the late 1800s, but the technique of roasting tomatoes before making soup is rooted in Mediterranean cooking traditions. Italian and French cooks have long understood that roasting vegetables concentrates their flavors and creates depth that cannot be achieved through other cooking methods.
The combination of tomatoes and basil is quintessentially Italian, celebrating the classic pairing that forms the foundation of countless Mediterranean dishes. This roasted version elevates the traditional tomato basil soup by incorporating techniques used in professional kitchens, where roasting vegetables is a standard practice for building complex flavor profiles in soups and sauces.
Ingredients
- 3 pounds fresh Roma tomatoes halved lengthwise
- 1 large yellow onion quartered
- 6 cloves garlic peeled
- 3 tablespoons olive oil
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 2 cups low-sodium vegetable broth
- 1/4 cup fresh basil leaves
- 2 tablespoons heavy cream
- 1 tablespoon balsamic vinegar
- 1/2 teaspoon sugar if needed
How to Make It
- Step 1: Preheat your oven to 425 degrees Fahrenheit. Line a large baking sheet with parchment paper and arrange the halved tomatoes cut-side up. Add the quartered onion and whole garlic cloves to the same pan.
- Step 2: Drizzle the olive oil over all vegetables and season with kosher salt and black pepper. Toss gently to coat everything evenly. Roast for 35-40 minutes until the tomatoes are caramelized and slightly charred at the edges.
- Step 3: Transfer all roasted vegetables to a large pot or Dutch oven. Add the vegetable broth and bring to a simmer over medium heat. Let it simmer for 10 minutes to allow flavors to meld together.
- Step 4: Remove from heat and add the fresh basil leaves. Using an immersion blender, blend the soup until smooth and creamy. Alternatively, transfer to a regular blender in batches, being careful with the hot liquid.
- Step 5: Stir in the heavy cream and balsamic vinegar. Taste and adjust seasoning with salt, pepper, or a pinch of sugar if the tomatoes are too acidic. Serve immediately garnished with fresh basil leaves and a drizzle of cream if desired.
Pro Tips
- Choose Roma tomatoes for the best flavor and texture as they have fewer seeds and more flesh than other varieties
- Do not skip the roasting step as it concentrates the tomato flavors and creates the signature caramelized taste
- For a dairy-free version, substitute the heavy cream with coconut cream or cashew cream for the same richness
