  • Baking Dish roughly 20cmx30cm
  • Pasta Pot


  • 350 grams pasta ideally fusilli, penne or rigatoni
  • 2 tins of tuna in springwater or brine drained and flaked
  • 2 leeks trimmed and sliced
  • 150 grams mature or sharp cheddar cheese grated
  • 200 ml double cream heavy cream
  • 1 tbsp fresh chopped parsley plus extra to garnish if desired
  • ½ tsp ground black pepper
  • ¼ tsp garlic powder
  • pinch salt to taste


  • Preheat your oven to 180°c/160 fan/350f and put a large pot of salted water on to boil.
  • Add the pasta to the pot and cook for 2 minutes less than recommenced on the packet instructions. Add the leeks to the pot for the final 2 minutes of cooking.*
  • Scoop out ¼ cup (4 tablespoons) of the cooking water from the pasta, then drain it.
  • In the same (warm) pot you used to cook the pasta, add the cream, the reserved pasta water, two thirds of the cheese (100g) plus the pepper, garlic powder and salt.
  • Mix well, then add in the tuna, pasta and parsley and stir again.
  • Transfer everything into a baking dish, give it another stir to make sure all the ingredients are evenly distributed, then sprinkle with the remaining cheese.
  • Bake in the oven for 15-20 minutes, until the cheese on top is golden brown.
  • Sprinkle with some extra chopped parsley and serve.


*for example, if the pasta packet recommends cooking for 10-12 minutes, you should cook the pasta for 6 minutes then add the leeks and cook for a further 2 minutes, 8 minutes in total.
