  • 4-6 garlic cloves, sliced
  • 1 28oz can crushed tomatoes or tomato sauce
  • 1/4 cup fresh parsley, chopped
  • 2 tsp oregano
  • 1/2 tsp red chilli flakes
  • 1/2 tsp sugar (optional)
  • 1/2 cup white wine
  • 1/2 cup kalamata olives
  • 1/4 tsp black pepper
  • Salt, to taste
  • 1/2 cup olive oil

For the garnish:

  • Drizzle of extra virgin olive oil
  • 2 Tbsp fresh parsley, chopped
  • 1/4 cup feta cheese (optional)


  1. Pre-heat the oven to 375°F
  2. Marinate the fish with salt, pepper, oregano and lemon juice for 30 minutes, or while you prepare the sauce.
  3. Heat the olive oil in a braiser pan on medium high heat.
  4. Add the onions and sauté until they get golden brown in colour (about 10 minutes).
  5. Add in the garlic and sauté for a couple of minutes.
  6. Add in the tomatoes and stir in salt, pepper, oregano, sugar, red chilli flakes, parsley and cook for a couple of minutes.
  7. Stir in the wine and simmer the sauce for 15 minutes.
  8. If you are using an oven proof dish, place the fish in the sauce such that there is a little sauce at the bottom and spoon the sauce generously over the fish.
  9. If using a separate baking dish, pour half the sauce in the bottom, place the fish and cover the fish with remaining sauce.
  10. Throw in the kalamata olives.
  11. Bake on the middle rack of the oven for 35 minutes, or until the fish is flaky.
  12. Drizzle extra virgin olive oil, garnish with parsley, feta and lemon slices if desired.
