This tomato soup is healthy but I didn’t make it deliberately healthier, it’s just how I make my tomato soup! It’s low in calories even so I added a good amount of cream because that’s how I like it. But you could also add less cream and this recipe would make a delicious soup too!
I promise after you tried this recipe with roasted tomatoes you don’t want to eat normal tomato soup anymore!
How to make Tomato Soup with Roasted Tomatoes
- You need a large enough pot that’s oven safe and fits most of the halved tomatoes cut side down. You could also use a sheet pan for roasting the tomatoes and then transfer them to a stock pot before adding the stock and blending.
- The flavor of the soup depends on the quality of the tomatoes you use. I recommend using ripe organic tomatoes, these taste best in my opinion.
- Add only as much cream as you like, this soup tastes great even without cream but I love a little bit of cream in it because it enhances the flavor and doesn’t add too many calories – this soup only got 182 calories for a big bowl!
To make the soup start with preparing the tomatoes – LOTS of them. You’ll need 3.5lbs (1.6 kg) fresh tomatoes for this recipe. Cut them in half and slice off any hard cores while you saute the chopped onions and garlic. Place the tomatoes cut side down into the pan, sprinkle with sugar and drizzle a little bit balsamic vinegar over them. The tomatoes will start to caramelize which adds so much flavor.
Don’t worry if you can’t fit all tomatoes cut side down into your pan. I always have to leave out a few halves which I add before I transfer the pan to the hot oven.
Going the extra step and roasting the tomatoes in the oven makes them cook in their own juices which makes them soft and sweet. This will be the best tomato soup you’ve ever tasted, well worth making it from scratch!
Once the tomatoes are cooked and soft, transfer the pan back to the stove, add the chicken or vegetable stock and the cream, and use a stick blender to whizz until smooth.
The taste of the freshly roasted tomatoes is incomparable! This soup is creamy and full of flavor.

Tools used for making this roasted tomato soup recipe
Immersion Blender: I love my hand blender! It’s great for making soups. You can blend right in the pot and it’s easy to clean and doesn’t need much space in my kitchen.

Stockpot: You need a large enough stock pot for this recipe. I like to use a pot like this one because you don’t make a mess when you puree the soup with the immersion blender in the pot.
