Follow our tasty step by step recipe for a Slow Cooked Tomato Salad, created by Roundhouse home economist, Amy Knight.


Serves 3-4

  • 500g mixed tomatoes – we used heirloom
  • a good drizzle of extra-virgin olive oil
  • sea salt flakes and freshly ground black pepper
  • a few sprigs fresh oregano, leaves only, chopped – or a few pinches of dried


  1. Begin by turning on the warming drawer to the highest setting (which is around 85°C), and allowing it to preheat whilst you prepare the tomatoes.
  2. Halve the smaller tomatoes, and quarter the large ones if you are using mixed sizes. Arrange, cut-sides up, on to a large baking tray.
  3. Drizzle generously with olive oil, then season well and scatter over the fresh or dried oregano.
  4. Place in the warming drawer for 4-6 hours, depending on how well ‘shrivelled’ you want the tomatoes to turn out!
  5. Arrange on to a serving platter, scatter over torn fresh basil leaves and drizzle over a little dressing. Delicious served with burrata and some crusty bread, or as an accompaniment to grilled meat or fish.
