I don’t have many words today (that’s a surprise) but this soup was actually made way back in March and I’ve been wanting to share it would you ever since. Since we grow tomatoes we’re always looking for new ways to use it, and this was such an easy and delicious way to share it.

The weather has been weird – hot during the day, and now the nights are getting pretty cold. Now that it’s getting into soup weather, and the fact that I’ve already had soup quite a lot already, it seemed prime time to share this soup recipe. This was definitely my favourite tomato soup to date, and it hits all the notes on creaminess, taste, texture and flavour. I’m tempted to compare to to a bisque because it’s also a nicely thick soup.

I’ve always been a fan of grilled cheese sandwiches and although I’ve had quite a lot less in the past few months, it’s the perfect addition to tomato soup if you ask me. I thought it would be great to serve the grilled cheese as croutons which taste magnificent on top of the tomato soup, already soaking up the flavour for you and still having it’s crispness.

If you’re not yet ready for soup weather, save this recipe for when you are – I guarantee you’ll love it!

    I tried this with the last of my fresh tomatoes and the recipe is wonderful – froze some of the soup for this winter.
    Your recipes are great, thanks.

  7. I absolutely love the idea of grilled cheese croutons and can’t believe they aren’t popular everywhere. I think they would be great in a salad too. I will definitely be making some of these babies. Thanks for the inspiration.
