This slow-cooked tomato tartine recipe is adapted from Cook Slow: Light and Healthy by Dean Edwards. Dean says, ‘Slow-cooked tomatoes (spiked with a few herbs and garlic) are a favourite of mine. I love the creaminess of the burrata, which is similar to fresh mozzarella, but if you can’t find it then you could use soft cheese or even some smashed avocado.’



  • plum tomatoes 6 large and ripe, halved
  • garlic 1 clove, crushed
  • thyme 2-3 sprigs, leaves picked, plus extra to serve
  • olive oil 1 tbsp
  • burrata 1 ball
  • sourdough 4 thin slices, toasted
  • rose harissa or regular harissa 2 tbsp


  • Step 1

    Heat the oven to 160C/fan 140C/gas 3 and line a baking tray with baking paper.

  • Step 2

    Put the tomato halves in a bowl with the garlic, thyme and olive oil, then season – toss to make sure the tomatoes are well coated. Scatter over the lined tray, cut-side up, and roast in the oven for 45 minutes-1 hour.

  • Step 3

    To serve, spread the burrata on the toast, then spoon on some of the harissa. Top with the roasted tomatoes, then sprinkle over a little more thyme to serve.

Slow cooker instructions
