Ingredients

- Tomato- Fresh Tomatoes work best.
- Garlic
- Olive Oil
- Salt & Black Pepper
- Basil.
- Lemon Juice
- Water- I have used plain water for thinning the soup. You may use vegetable broth as well.
- Coriander Leaves (Cilantro)
- Bread or croutons (Optional)

How To Make Roasted Tomato Garlic Soup
Step 1. Roast the Tomatoes and Garlic
While you prep tomatoes and garlic, preheat your oven to 190°C for about 10 min.
Line the baking tray with a greased baking sheet (I have greased it without the sheet) and place the roughly chopped tomatoes and garlic on it evenly. Drizzle with salt, black pepper, and olive oil.
Pls Note If you are using garlic heads, cut off the top of the garlic head to expose the cloves, drizzle with olive oil, and then place.
It will take about 10-15 min in an OTG (I have used an old one) for roasting. In the oven, it may take about 20-25 min. An air fryer would take 15 min depending upon the number of tomatoes you use. You may have to batch roast for more quantities. Roast until they become soft and start to caramelize.



Step 2 Cool and Blend The Ingredients
Cool off the baked tomatoes and garlic in a food processor or use an immersion blender.
If you have used garlic head, squeeze out the roasted garlic and discard the peel.

Step 3 Temper The Smooth Tomato Paste
In a large pot, heat 1 tablespoon of olive oil over medium heat. Add the blended tomato garlic paste. If you wish to add any vegetables, add them at this step.
Pour in the water to adjust consistency. (You may use vegetable stock as well) and salt, and pepper to taste. Let the mixture boil, then reduce the heat and let it simmer for about 10 minutes, allowing the flavors to meld together. Add lemon juice.




Step 4. Serve
Garnish with coriander and basil leaves. Add a drizzle of cream and serve the homemade Roasted Tomato Garlic Soup with your choice of bread for a comforting meal.

Expert Tips
- Use fresh and ripe tomatoes as they have the natural sweetness.
- Roast the garlic until it's soft and golden and don't over-roast or it might taste bitter. I recommend roasting everything together for the best blending of flavors.
- You may roast the tomatoes and garlic in an oven, stove-top, direct flame, or using an air fryer. All these methods might vary in the roasting times and in the flavor a bit. I have used an old OTG and it does a quick job of roasting. While oven would take about 20-25 min, air fryer might take just 15 min to roast.
Recipe FAQs
Well, usually the thickener in soup is heavy cream or cornstarch. This soup makes fresh tomato puree of the roasted tomatoes and doesn't sieve it, and that's how the soup is naturally thick. You may add potatoes and carrots as well to make this soup thick.
In a large pot, sauté onions and garlic in olive oil until translucent. Add carrots, celery, canned whole and crushed tomatoes, vegetable stock, and sugar.
Simmer until vegetables are tender, then blend until smooth. Season to taste, garnish with basil leaves and serve with a dollop of heavy cream if desired.
