  • 2 kg approximately 4lb ripe tomatoes (I use a mixture and like to roast them with the vines)
  • 2-3 tablespoons olive oil
  • 4-6 garlic cloves
  • 2 sprigs fresh rosemary
  • small handful fresh thyme leaves
  • ½ teaspoon chilli flakes/red pepper flakes
  • 1 teaspoon salt
  • black pepper to taste

for the sauce

  • 2 red onions finely chopped
  • 2-3 garlic cloves thinly sliced
  • 2 teaspoons Italian herbs
  • 1-2 teaspoons smoked paprika to taste
  • salt & pepper to taste
  • 1-2 teaspoons sugar optional
  • ½-1 cup vegetable stock


  • Pre-heat the oven to 200ºC.
  • Place the tomatoes in a roasting tray then add the olive oil and flavourings.
  • Mix to combine.
  • Place in the oven and allow to roast for 30-45 minutes or until the tomatoes are soft and starting to char.
  • Remove and set aside.
  • Heat a splash of oil in a deep pot then add the onion and allow to soften for a few minutes.
  • Add the garlic and allow to saute for a minute before adding the herbs, spices and roasted tomatoes.
  • Add the sugar (if using) then pour in the stock.
  • Turn the heat down and allow to cook for 15-20 minutes until the sauce has thickened slightly.
  • At this point you can keep the sauce rustic and chunky and freeze in ziploc bags or keep in the fridge in an airtight container for up to a week.
  • Alternatively, blend until as smooth as you prefer and then freeze/keep in the fridge.
