  • Stir in the cheese till mixed in and serve.

Notes

Tips 
  • When you first open there will be a bit more liquid, but if you mix and let stand for a bit the liquid will be absorbed.
  • And if you like your spaghetti with lots of sauce, add an extra half a cup of stock or cream.
  • Double or (even triple) the ingredients in this recipe to feed a crowd without having to adjust the cook time!
  • Feel free to sprinkle in even more Parmesan cheese, or add some grated mozzarella for extra cheesy goodness.
  • No spaghetti on hand? You can swap in the pasta noodles of your choice.
