Ingredients
- 3 lbs ripe tomatoes, halved
- 1 large yellow onion, cut into wedges
- 6 cloves garlic, peeled
- 3 tbsp olive oil
- Salt and pepper, to taste
- 3 cups vegetable or chicken broth
- 1 cup fresh basil leaves

- 1/4–1/2 cup heavy cream (optional for creaminess)

How to Make Roasted Tomato Basil Soup
Follow these straightforward but flavor-building steps for the perfect tomato basil soup.
1. Roast the vegetables
Preheat your oven to 425°F (220°C). Spread tomatoes, onion wedges, and garlic cloves on a lined baking sheet. Drizzle olive oil on top and season generously with salt and pepper. Roast for 25–35 minutes, or until tomatoes have softened, edges are blistered, and the garlic is golden.
2. Transfer to a pot
Carefully move the roasted vegetables and accumulated juices into a large pot. This is where the soup begins to take shape.
3. Add broth and basil
Pour the vegetable or chicken broth into the pot. Add fresh basil leaves; their fragrance will start to bloom immediately.
4. Simmer and blend
Bring the mixture to a gentle simmer for 10 minutes to meld the flavors. Then remove from heat and blend using an immersion blender. Alternatively, blend in batches using a high-speed blender (careful with the heat!).
5. Adjust consistency
Too thick? Add more broth. Too thin? Continue simmering until reduced to your preference.
6. Add optional cream
For a silky, luxurious feel, stir in heavy cream. You can also leave it dairy-free if preferred.
7. Taste and season
Adjust salt, pepper, and optional sugar to balance acidity. Add red pepper flakes for heat.
8. Serve hot
Top with more fresh basil, cracked black pepper, or a swirl of cream. Add croutons or grilled cheese for the ultimate pairing.
Tips for the Best Roasted Tomato Basil Soup
Use ripe tomatoes
The sweeter the tomato, the better your soup. Roasting intensifies their natural flavors, but starting with high-quality produce is key.
Don’t skip roasting
It’s the heart of this recipe — caramelization equals flavor.
Blend until silky
Use a high-powered blender for the smoothest result. If you prefer a rustic soup, blend partially for light texture.
Add cream cautiously
Start with a small amount and increase until your preferred richness is reached.
Balance the acidity
Depending on your tomatoes, a teaspoon of sugar can transform the final flavor.
Variations
Creamy Tomato Basil Soup
Add ½ cup heavy cream or coconut milk for silky smoothness.
Spicy Tomato Soup
Add red pepper flakes, cayenne, or a roasted jalapeño before blending.
Smoky Roasted Tomato Soup
Include smoked paprika or roast a red bell pepper along with the tomatoes.
High-Protein Version
Stir in cooked white beans before blending.
Vegan Tomato Basil Soup
Use vegetable broth and skip cream — or swap with coconut cream for richness.
