Step-by-Step Cooking Instructions
1. Prepare and Roast the Vegetables
- Preheat your oven to 425°F (220°C).
- Slice the tomatoes in half and place them cut-side up on a baking sheet.
- Cut the tops off the garlic bulbs and drizzle them with a little olive oil. Wrap each bulb in foil and add them to the sheet pan.
- Drizzle the tomatoes with olive oil, sprinkle salt and pepper, and roast for 35–40 minutes, or until the tomatoes are softened and slightly caramelized.
2. Sauté the Aromatics
- In a large pot, heat 1 tablespoon of olive oil over medium heat.
- Add the chopped onion and cook until soft and fragrant, about 5–7 minutes.
3. Blend the Soup Base
- Squeeze the roasted garlic cloves out of their skins.
- Add the roasted tomatoes, garlic, sautéed onion, and fresh basil to a blender.
- Pour in the vegetable broth and blend until smooth.
You may need to work in batches depending on blender size.
4. Simmer the Soup
- Pour the blended mixture back into the pot.
- Bring the soup to a gentle simmer and cook for 10–15 minutes to deepen the flavors.
- Taste and adjust seasoning with salt and pepper.
- Stir in heavy cream if you want a richer, silkier soup.
5. Serve and Enjoy
Ladle the hot soup into bowls, garnish with basil or a drizzle of cream, and enjoy the warm, comforting aroma.
Tips for Customizing the Recipe
- Add spice: A pinch of red pepper flakes or a chopped jalapeño enhances heat.
- Make it creamy without dairy: Substitute coconut milk or cashew cream for heavy cream.
- Boost the vegetables: Add roasted carrots, bell peppers, or celery for added depth.
- Thicken the texture: Mix in a small handful of cooked rice or a slice of stale bread before blending.
- Enhance umami: A splash of balsamic vinegar or a spoonful of tomato paste brings more richness.

Notes
- Roasting the garlic and tomatoes enhances the natural sweetness and depth of flavor—don’t skip this step.
Soup can be made ahead of time and stored in the fridge for 3–4 days; flavors often improve the next day.
FAQs
1. Can I use canned tomatoes instead of fresh?
Yes! If fresh tomatoes aren’t available, canned whole or crushed tomatoes work well. Choose high-quality canned tomatoes for the best flavor, and reduce the roasting time since they’re already cooked.
2. How long does roasted garlic tomato soup last in the fridge?
The soup keeps well for 3–4 days when stored in an airtight container. The flavors often deepen, making it even more delicious the next day.
3. Can this soup be frozen?
Absolutely. Freeze the soup (without cream added) for up to 3 months. Add cream after reheating to maintain a smooth texture.
4. How can I make the soup thicker?
For a thicker consistency, blend in a small piece of stale bread, a handful of cooked rice, or roast an extra tomato. Simmering a bit longer also naturally reduces and thickens the soup.
5. What can I use instead of vegetable broth?
Chicken broth is a great alternative and adds a savory depth. Water can work in a pinch—but add extra seasoning to enhance flavor.
Conclusion
Roasted garlic tomato soup brings together simplicity, warmth, and bold flavors in a way that feels both comforting and impressive. The roasting process transforms everyday ingredients into a vibrant, aromatic dish that stands beautifully on its own or pairs perfectly with your favorite sides.
