  • 400 g white fish fillets
  • 6 anchovy fillets plus oil from the can.
  • A quarter of an onion, diced

  • 400 g tin crushed tomatoes
  • 2 tbsp capers
  • 10 black olives
  • Zest and juice of a lemon
  • 400 g silverbeet, loosely chopped


  • Heat a non-stick frying pan to medium heat, add the anchovies and a splash of the oil from the anchovy tin. 
  • Add the onions, garlic and chilli. Saute until onions are soft, stir with a wooden spoon so the anchovies get crushed up into the onion mixture.
  • Add the tin of tomatoes, and stir, add the capers and olives, stir them through.
  • Turn down the heat and simmer for 10 minutes, occasionally stirring. 
  • While that is cooking, preheat the oven to 180°C/356°F (bake).
  • Place the fish fillets in a deep-sided baking tray. 
  • When the sauce has finished cooking, pour it over the fish, and sprinkle over the lemon zest. Bake in the oven for 15 minutes. 
  • While that is cooking, heat a large frying pan to medium heat. Add the silverbeet and squeeze over the lemon juice, toss the leaves until lightly wilted.
  • Plate up the silverbeet, place the fish on top and add lots of the flavoursome Puttanesca sauce.
