This has become my favorite tuna mornay recipe. It is slightly fiddly but worth it! Great when the orange tree is covered in fruit. Reduced fat ingredients can be used.

  • 3 slices white bread, torn
  • 1 tablespoon finely grated orange rind
  • 1 cup chopped fresh flat leaf parsley
  • 1/2 cup coarsely grated parmesan cheese
  • 1/2 pound dry macaroni pasta
  • 1/4 cup cornflour
  • 1 cup chicken stock
  • 1/2 cup white wine
  • 1/3 cup fresh orange juice
  • 1 tablespoon olive oil
  • 1 leek, ends trimmed, thinly sliced
  • 1 pound tuna in water, drained and flaked

White sauce

  • 1/4 cup oil
  • 1/4 cup plain flour
  • 2 cups milk
  • 1/2 cup natural yoghurt
  • 1/2 cup coarsely grated cheddar cheese


  1. Preheat oven to 350 F (180 C).
  2. Place the bread, orange rind, half the parsley and half the parmesan in a food processor and process until finely chopped.
  3. Cook the pasta and drain.
  4. Meanwhile, cook the white sauce by heating the oil in a saucepan. Add the flour and cook, stirring for about a minute. Gradually add the milk, whisking until combined.
