Harvest Tomato Sauce

Prep time: 15 mins
Cook time: 2 hours
Makes: approx 3 cups



  1. Preheat oven to 160°C. Prepare the tomatoes, capsicums and onion and place them in a large roasting dish lined with baking paper. They need to be in a single layer so they roast and caramelise rather than stew, so use two roasting dishes if necessary.
  2. Add the garlic, rosemary leaves and chilli, if using. In a small bowl mix together the tomato paste, sugar, olive oil, salt and pepper. Spoon this mixture over the vegetables and stir through them to coat evenly.
  3. Bake for about 2 hours or until the vegetables are starting to caramelise and shrivel a little.
  4. Allow the vegetables to cool then purée in a food processor or blender. The sauce will keep in the fridge for up to a week or can be frozen. Alternatively, bring the puréed sauce to a boil and while it is very hot, pour it into sterilised jars. Cover then seal. Sealed jars will keep for months in the pantry.
