Roast Tomato Basil Soup

Tomato and Basil SoupThis Roast tomato basil soup is so tasty and healthy. By roasting the tomatoes they become way more intense and sharp making the soup really tangy. Deseeding the tomatoes helps them to roast better but I saved the seeds and strained them to make up the stock just to save every drop of tomato flavour. This is totally optional though.

While there is a little oil and butter in this soup, this recipe makes a really large quantity and the rest of the ingredients are really healthy and low-calorie so this is perfect for January if you’ve made some ambitious new years resolutions.

If you’d like to serve this as a starter for a dinner party it will definitely go down well but you may need to tart it up a bit because it’s not the prettiest thing I’ve ever seen. Some croutons here would be perfect!
