This tomato basil soup brings together the deep, naturally sweet flavor of roasted Roma tomatoes, aromatic basil, tender vegetables, and a touch of balsamic vinegar for a beautifully balanced bowl.
Roasting the tomatoes first concentrates their flavor while allowing their centers to remain juicy, creating a richer foundation for the soup.
Fresh garlic, yellow onion, and carrots add savory depth, while vegetable broth gives the mixture a smooth, spoonable consistency.
Once the roasted tomatoes are combined with the softened vegetables, broth, vinegar, and thyme, everything simmers together so the flavors can develop.
Fresh basil is added after blending, preserving its bright herbal character and giving the finished soup a fresh, fragrant quality.
The texture is wonderfully smooth after blending, while the roasted tomatoes provide a deeper flavor than a simple stovetop tomato soup.
A drizzle of extra-virgin olive oil, fresh basil, and a final seasoning of salt and freshly ground black pepper complete the bowl.
The soup is especially appealing when served warm alongside a grilled cheese sandwich or plenty of crusty bread for dipping.
Its combination of rich roasted tomato flavor, delicate herbs, and gentle acidity makes it comforting without feeling overly heavy.
Whether served as a cozy lunch or as part of a simple dinner, this soup offers an inviting way to enjoy fresh tomatoes and basil in a polished, flavorful dish.

Roasted Tomato Basil Soup
Ingredients
Equipment
Method
- Roast the Tomatoes: Preheat the oven to 350°F and line a large baking sheet with parchment paper. Arrange the halved Roma tomatoes cut side up, drizzle them with 2 tablespoons of the olive oil, then season with sea salt and freshly ground black pepper. Roast for 1 hour, until the edges just begin to shrivel while the centers remain juicy.
- Soften the Vegetables: Pour the remaining 2 tablespoons of olive oil into a large pot and warm it over medium heat. Add the chopped onion, carrots, garlic, and ½ teaspoon salt. Cook for about 8 minutes, stirring as needed, until the vegetables become soft.
- Simmer the Soup: Add the roasted tomatoes to the pot along with the vegetable broth, balsamic vinegar, and fresh thyme leaves. Stir to combine, then let the mixture simmer for 20 minutes so the flavors come together.
- Blend Until Smooth: Allow the soup to cool slightly before transferring it to a blender. Work in batches if necessary and blend until the soup is smooth.
- Add the Basil: Add the loosely packed fresh basil leaves to the blended soup and pulse until the basil is incorporated.
- Season the Soup: Taste the blended soup and adjust the seasoning with salt and freshly ground black pepper as needed.
- Serve the Soup: Ladle the finished tomato basil soup into bowls and garnish each serving with fresh basil leaves.
Notes
- Roast the tomatoes cut side up so their juices remain inside while the edges develop a slightly shriveled, concentrated texture.
- Keep the roasted tomato centers juicy; the source specifically calls for roasting until the edges just begin to shrivel.
- Divide the olive oil between roasting the tomatoes and softening the vegetables for the intended cooking method.
- Let the soup cool slightly before blending, and work in batches if needed.
- Add the fresh basil after blending and pulse it into the soup to retain its fresh herbal character.
- Taste the soup at the end and adjust the salt and freshly ground black pepper to your preference.
- Garnish each bowl with additional fresh basil leaves for a simple finishing touch.
Chef’s Secret
The most useful step for developing this soup’s flavor is giving the Roma tomatoes their full roasting time.
Arrange them cut side up and roast at 350°F until the edges just start to shrivel while the centers are still juicy.
This concentrates the tomatoes without drying them out, creating a deeper tomato flavor that carries through the blended soup.
Avoid roasting them beyond the point described in the recipe, since the juicy centers are part of the desired result.
When blending, work in batches if necessary rather than overfilling the blender.
Adding the fresh basil only after the soup has been blended also keeps its flavor fresh and noticeable instead of blending it for an extended time.
Serving Suggestions
Serve this tomato basil soup warm with a grilled cheese sandwich for a classic pairing that adds crisp, toasted texture and richness.
Crusty bread is another practical choice for dipping into the smooth soup.
For a simple presentation, garnish each bowl with fresh basil leaves just before serving.
The soup can also be served as a comforting starter before a larger meal, with the basil garnish providing a fresh visual and herbal finish.
Conclusion
This tomato basil soup transforms fresh Roma tomatoes into a smooth, deeply savory bowl through roasting, simmering, and blending.
The combination of basil, thyme, garlic, vegetables, vegetable broth, and balsamic vinegar creates balanced flavor with a fresh herbal finish.
Served with grilled cheese or crusty bread, it makes a comforting meal that highlights the natural character of roasted tomatoes.
