  • 2 tablespoons olive oil
  • 1 large onion sliced
  • 3 cloves garlic crushed or grated
  • 300 g fusilli pasta (or your favourite shape)
  • 350 ml passata
  • 650 ml water (use the empty passata jar to measure)
  • Salt and pepper to taste
  • 250 g mascarpone
  • 120 g tinned tuna drained
  • 150 g tinned sweetcorn drained (or use frozen)
  • 200 g broccoli chopped into very small florets
  • 150 g cheddar cheese grated
  • 50 g panko breadcrumbs (or normal breadcrumbs)
  • Green salad to serve optional


  • Put the oil in a wide ovenproof pan and add the sliced onion. Fry for 3 minutes over a low heat, with the lid on, or until softened. Add the garlic and cook for a further 2 minutes, with the lid off.
  • Put the pasta, passata and water into the pan, together with the salt and pepper, and bring to the boil. Cover with a lid and cook for 10 minutes, stirring once or twice until the pasta is nearly al dente. Meanwhile preheat your oven to 220C / 200C fan / gas mark 7 / 425F.
  • Remove the lid and add in the mascarpone, tuna, sweetcorn and broccoli. Stir to mix everything together thoroughly. Bring to a gentle simmer and then turn off. Mix the cheddar and breadcrumbs and sprinkle over the top of the pasta bake.
  • Cook the pasta bake uncovered in the preheated oven for 10-15 minutes until the cheese is melted and bubbling, and the pasta is cooked to your liking.
  • Serve with a green salad.


In order to make this dish truly a one pot dish you need to cook it in a wide, fairly deep pan that is both suitable to go on the stove and in the oven. I use my much loved Le Creuset style sauté pan for this. But anything will do so long as it can be used on the hob and in the oven. If you don’t have anything suitable, then you will need to transfer the dish from a saucepan to an oven dish for the final step.
