History and Background
Tomato soup gained popularity in America during the early 1900s when Campbell first introduced their condensed version, but the practice of roasting tomatoes for soup dates back centuries to Mediterranean cooking traditions. Italian cooks discovered that fire-roasting tomatoes over open flames concentrated flavors and created a richer base for soups and sauces.
The addition of basil to tomato-based dishes represents a classic pairing that originated in Southern Italy, where both ingredients grew abundantly. This combination became so fundamental to Italian cuisine that it inspired the colors of the Italian flag. Modern roasted tomato basil soup represents an evolution of these traditional techniques, using oven-roasting to achieve the same flavor concentration that ancient cooks accomplished over wood fires.
Ingredients
- 3 pounds Roma tomatoes halved lengthwise
- 1 large yellow onion quartered
- 6 cloves garlic peeled
- 3 tablespoons olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 4 cups vegetable broth
- 1/2 cup heavy cream
- 1/4 cup fresh basil leaves
- 2 tablespoons fresh basil chopped
- 1 tablespoon sugar
- 1/2 teaspoon dried oregano
How to Make It
- Step 1: Preheat oven to 425°F. Line a large rimmed baking sheet with parchment paper.
- Step 2: Arrange halved tomatoes cut-side up on prepared baking sheet along with quartered onion and whole garlic cloves. Drizzle with olive oil and season with salt and pepper. Toss to coat evenly.
- Step 3: Roast for 35-40 minutes until tomato edges are caramelized and onions are golden brown. Remove from oven and let cool for 10 minutes.
- Step 4: Transfer roasted vegetables to a large pot. Add vegetable broth, sugar, and oregano. Bring to a boil, then reduce heat and simmer for 15 minutes.
- Step 5: Remove from heat and stir in fresh basil leaves. Using an immersion blender, puree soup until smooth. Alternatively, carefully transfer to a regular blender in batches.
- Step 6: Return soup to pot if using regular blender. Stir in heavy cream and chopped fresh basil. Taste and adjust seasoning with additional salt and pepper as needed.
- Step 7: Serve immediately in bowls, garnished with additional fresh basil leaves and a drizzle of cream if desired.
Pro Tips
- Choose Roma or plum tomatoes for best results as they have less water content and more concentrated flavor when roasted
- Do not skip the roasting step as this is what creates the deep, caramelized flavor that sets this soup apart from stovetop versions
- For a lighter version, substitute half-and-half or whole milk for heavy cream, though the texture will be less rich and velvety

Frequently Asked Questions
Can I make this roasted tomato basil soup recipe ahead of time?
Yes, this soup actually improves in flavor when made ahead. Store covered in refrigerator for up to 3 days or freeze for up to 3 months. Reheat gently and stir in fresh basil before serving.
What type of tomatoes work best for roasting?
Roma or plum tomatoes work best because they have lower water content and more flesh, which concentrates better during roasting. Avoid very juicy varieties like beefsteak tomatoes.
Can I make this soup dairy-free?
Absolutely! Simply omit the heavy cream or substitute with coconut cream for richness. The roasted tomato flavor will still be delicious and the texture creamy from the blended vegetables.
