Roasted Tomato Soup with Pesto Cheese Toasties


Roasted Tomato Soup with Pesto Cheese Toasties

Roasted Tomato Soup

As the crisp air settles in and winter hues paint the landscape, naturally I start to crave the comfort of warm and hearty dishes, like my take on the classic tomato soup. 

Everyone has their own way of making it, and I have to say I very rarely make this the exact same way each time. Sometimes I roast the veg, and other times when I’m in a hurry, I’ll just throw it all into a pot for the boil. But if I had to choose the ultimate version it would be this!

This isn’t the tomato soup you remember from your childhood; it’s a next-level creation, bursting with rich, roasted flavours and aromatic herbs. Ripe tomatoes, shallots, garlic, red capsicums, and carrots are caramelised to perfection in the oven, then blended into a velvety, savoury soup, finished with fresh basil and a dollop of creamy Greek yoghurt. Paired with crispy sourdough toasties, filled with melty, stretchy mozzarella and homemade basil pesto, this dish is the epitome of winter comfort. Each bite of the crunchy, cheesy toastie dipped in the flavourful soup will warm you from the inside out, making it the perfect meal for a chilly winter day.

This also pairs perfectly with my Cheesy Garlic Bread (linked here)

  • Brush the outside of each sandwich with olive oil and sprinkle with grated Parmesan cheese.
  • Fry the sandwiches in a pan with a bit of olive oil until crispy, toasted, and golden brown on both sides.
